Did you know this 1940’s sex symbol invented Wi-Fi?

How often do you think ‘Thank God for Wi-Fi’? Well it’s not God you should be thanking, it’s Hollywood bombshell Hedy Lamarr.

Although better known for being the most beautiful woman in the world, you have the brains of Hedy Lamarr to thank every time you use your mobile phone, a Wi-Fi connection or any Bluetooth technology.

Hedy, born Hedwig Eva Maria Kiesler in Vienna in 1913, was keenly interested in science when she was a child, yet ended up being known as a star of Hollywood, featuring in films such as “Samson and Delilah” (1949), “Boom Town” (1940), “The Conspirators” (1944) and the Czechoslovakian film “Ecstasy” (1933).

She lived a life of sex and science, and although a brilliant actress, Lamarr’s greatest achievement and long-term contribution to society was not her role in Hollywood, but as an inventor of the very thing our generation cannot live without.

Along with composer George Antheil, she co-invented early techniques used for spread-spectrum communications and frequency hopping.
These technologies were originally designed and used for military purposes where they aided communication for decades.

Nowadays they form the core of many of today’s most popular wireless devices.

During the 1930’s, Lamarr witnessed first hand the potential dangers that came with the rise of the Nazi party whilst she was married to her first husband, Austrian arms manufacturer Friedrich Mandle. After escaping that marriage and moving to California, she became a Hollywood star and between shots and takes, began her practice of inventing things.

She viewed it as a hobby; she didn’t have to work on ideas, they just came to her naturally. Uninterested in partying or drinking, Hedy created an ‘inventor’s corner’ in her Hollywood home where she would focus on her projects between filming movies. With only a few movies to film a year, each one taking a month to film, Lamarr had plenty of time on her hands to devote to her fondness of science and technology.

Although few of her ideas came to fruition, the sinking of a cruise ship by Nazi U-boats in 1940 inspired her to action. She devised the idea of a radio signal that would hop between radio frequencies, preventing it from being jammed. This allowed airplanes to safely guide nearby torpedoes without being jammed.

After working alongside eachother on their idea for several months, Lamarr and Antheil sent a description of it to the inventors council in December 1940.

2 years later in August 1942, they were granted a patent for their “secret communication system” which they then gave to the U.S. Navy for no cost.

Frustratingly, the military did nothing with the idea or patent and nothing was implemented until the 1960’s, long after the patent had expired.
The military completely underestimated her brains, and instead focused on her body, advising that she’d contribute more to the war effort as a pinup, selling kisses. But she was so much more than that, and their invention has become the core technology behind Wi-Fi networks as well as Code Division Multiple Access (CDMA) cellphones and Bluetooth.

Despite the majority of us thinking multiple times a day ‘What on earth would we do without Wi-Fi?’ hardly anyone knows of the important contribution that Hedy Lamarr gave to this technology that nowadays we couldn’t live without.

Dubbing Lamarr’s innovative creation ‘spread spectrum technology’, The Electronic Frontier Foundation honoured her with its Pioneer Award in 1997, 3 years before her death.

Her invention was inspired by secret communications to win a war, but has given the world so much more.

What’s The Worst Excuse for Bad Wi-Fi You’ve ever Heard?

When you get home from a lovely week away, ready to catch up with emails and get back to work only to find that your internet is out… Nightmare!

We went to Devon for a week, which was lovely. In-keeping with our digital detox from the other week, our beautiful little countryside cottage had awful Wi-Fi which nudged me in the direction of avoiding social media, which turned out to be rather refreshing.

However, once home, I was keen to get back online – Yes to share a few photos, but also to get back in the zone of work before Monday arrived.

So I switched on my laptop, connected to the router, but no web pages were opening. The Slack app wasn’t letting me read my messages on my phone. No online video streaming on the TV to distract the kids!

What was going on?

I sent a text to both my neighbours – One was fine, but the other had had no phone line or broadband earlier in the week either.

Time to contact our broadband provider. After a few text messages, it transpired there was a fault on our line and they would have to send an engineer out. This would hopefully be within 72 hours but could take up to 5 days. Of course, this was Friday afternoon, and of course, the 72 hours doesn’t include the weekend. Time to text the boss.

Thankfully the engineer arrived on Monday morning and fixed the issue.

And the problem? Rats! Apparently rats had gnawed through the cables and they had to be replaced.

I work from home most of the time so it’s pretty important that I have a reliable internet connection. Didn’t think I’d be getting back from holiday and straight away having to tell the boss that I couldn’t get online because of rats chewing cables. It’s a bit “The dog ate my homework, miss” isn’t it?!

Anyone else had a rodent related outage? What’s the worst reason for bad Wi-Fi you’ve heard? Or used?? We’d love to hear them.

Here at Geekabit, we can’t control rats getting in to external cabling, but we can do a lot of other things to help improve your Wi-Fi. Check out our website and see what we can do for you and your business.

What lengths would you go to, to improve your Wi-Fi speed?

Here at Geekabit we’ve always had a bit of a soft spot for Wales, and now even more so with the boss recently making his beautiful Welsh lady his wife. So when we came across an article about the residents of Michaelston-y-Fedw digging a 15 mile long trench in order to be able to lay super-fast cables, it really made us smile.

The Welsh residents of this small village just a stones throw from our Cardiff based office, were desperate for faster Wi-Fi (aren’t we all, sometimes?) and took matters into their own hands.

With a population of just 300, it’s probably not at the top of service providers list for super-fast cabling, but that doesn’t mean that these villagers weren’t as exasperated as the rest of us when it comes to slow Wi-Fi.

They described their internet connection as feeble, and so decided to dig the trench needed for fibre broadband cables themselves.
It took thousands of volunteer hours from farmers, teachers and retired people from the tiny Welsh village – A huge community effort, which has resulted in the first households being connected successfully. By the Autumn, 90% of homes in the village should be enjoying a massive improvement in internet speed, having gone from 4Mbps to 1000.

Like so many grand schemes, the original plans were hatched in the local pub. Landlord Ben Longman had recently paid for high speed broadband before realising that it wouldn’t work.

With the whole community seemingly disgruntled with the poor Wi-Fi, they went on to set up a community interest company and secured a Welsh government grant.

It was decided that costs for each household should be kept to an absolute minimum so the villagers rallied together to complete as much of the work as possible themselves. While some of the work was completed by local farm workers who were hired to help with the dig, much of the digging efforts was completed by villagers who excavated trenches from their home perimeter and up to the external wall where the fibre needed to enter their home.

It’s an incredible community achievement, with organisers commenting that they almost couldn’t believe what they had managed to do when they all came together.

It now takes less than a minute to download a film, when it used to take a few days. Imagine settling down to watch a movie, only to have to wait until the following night!

One of the men, and husband to one of the organisers who helped with the project was 71 year old Jum Dunk who had lived in the village for over 4 decades. Taking part in the dig led to him making new friends that he hadn’t met before – It might be a small Welsh village, but the initiative brought together people from all different walks of life that may not have had the opportunity to meet.

And if you’re thinking that fast Wi-Fi isn’t quite enough of a reward for digging a 15 mile trench, you’ll be pleased to know that each household that applied before 30 April were connected free of charge with their first year’s service also free.

Here at Geekabit we are so community minded, and just love hearing of success stories like this where people show what can be achieved when we come together. And even better when it’s in our own field too.

Digital Detox Destinations

Our Director, Steve, has recently got married and has just got back from his honeymoon – A celebration of his nuptials but also a much needed break from the digital demands of his world. While I (and probably his new wife, too) insisted that he switched off whilst he was away, I wouldn’t be surprised if he had the odd sneaky peek at emails just to make sure that we were ticking over okay.

Which got me to thinking… Is there anywhere left in this world that forces you to have a proper digital detox?

As Brits, we have what can only be described as an addiction to the internet. Any moment we stop and sit down like waiting for a train or a bus, you’ll find heads pointed down at brightly lit screens, eyes devouring the media on the screen. A lot of times, they don’t even need to sit down!

We go to the pub to catch up with friends in person, see each other face to face, but still pull out our phones and ask ‘What’s the Wi-Fi password?’

A staggering 99% of young Brits (16 to 35 years old) use the internet (who are the other 1%? What do they do with their time?). What’s even more staggering is that these internet users are consuming media online for 10 hours per day, with the majority being viewed through a smartphone or tablet.

So it would seem that Britain really could be in need of a Digital Detox, and somewhere where it’s not left merely to willpower alone. With an internet addiction like this, there really is no other way than Cold Turkey (not one of the destinations, I’m afraid…)

Akamai, content delivery network and cloud services provider, have compiled a list of countries that would fit the bill.

Due to a lack of infrastructure, these 35 countries have a user penetration rate of less than 20% – This means that only 1 in 5 of the residents of these countries can access the internet.

1. Guatemala
2. Honduras
3. Nicaragua
4. El Salvador
5. Senegal
6. Burkina Faso
7. Mali
8. Ghana
9. Cote d’Ivoire
10. Benin
11. Algeria
12. Libya
13. Sudan
14. Eritrea
15. Ethiopia
16. Cameroon
17. Uganda
18. Rwanda
19. D.R. Congo
20. Malawi
21. Zimbabwe
22. Zambia
23. Namibia
24. Madagascar
25. Mozambique
26. Angola
27. Yemen
28. Pakistan
29. Turkmenistan
30. Nepal
31. India
32. Bangladesh
33. Sri Lanka
34. Myanmar
35. Indonesia

Obviously, there are some countries on this list that it’s not possible to visit due to the foreign office advising against travel to certain places because of civil unrest, war and poverty. Obviously these reasons also impact why internet usage is so low.

However, there are countries on this list that are the perfect retreat for a bit of solitude and well worth a trip. Telegraph Travel pinpointed some of them earlier this year, including a beach holiday in Nicaragua, a walking holiday through the Himalayan foothills of Ladakh, India, and a three-day trek from Kalaw to Inle Lake in Myanmar.

You could also do some lemur spotting in Madagascar, hop between islands in Indonesia, visit the rock-hewn churches of Ethipoa, track down the breathtaking sight of mountain gorillas in the DRC, or explore the utterly desolate coastline and desert of Namibia. They might be the most photogenic of opportunities, but you won’t be posting those pictures on Instagram until your feet are back on British soil.

There are plenty more incredible travel destinations on this list too like Guatemala, Senegal, Malawi, Mozambique, Turkmenistan, Sri Lanka and Nepal.

This list is of course not definitive, and there will be other internet-free places just as worthy of a holiday to satisfy the needs of a detox from digital life. You might want to scream from the top of the Facebook mountains about meeting Kazakh eagle hunters but you’ll be far from towns, roads and mobile reception in the real-life Altai Mountains. (The reason this one didn’t make the list is due to most of the population living in Ulaanbaatar which has excellent connectivity).

Other areas off the beaten track and away from the pulls of digital media could be Russia’s far east where you’re more likely to meet a bear than a person, Chilean Patagonia, the USA’s largest protected area Wrangell-St Elias National Park in Alaska, and The Yukon in Canada which is 80 per cent Wi-Fi-free.

Shockingly, Steve didn’t choose any of these destinations for his honeymoon… I can’t think why?

Should Venues Provide Free Wi-Fi?

Should UK venues offer free Wi-Fi to delegates and visitors? The debate is a fierce one and not showing any signs of diminishing. ESSA (Event Supplier Services Association) and ABPCO (Association of British Professional Conference Organisers) have widely campaigned the issue with differing views.

Below you’ll find a ‘Question Time’ style discussion between the Chairs of both associations – John Robson for ESSA and Michael Foreman for ABPCO. Or skip to the end for a conclusion of their points.

 

Just how important do you see the provision of Wi- Fi to be within a venue, to ensure the success of an event, be that a conference, show or exhibition?

Robson: It is absolutely essential these days. We are becoming increasingly dependent upon connectivity to run our personal and business lives and this does not stop when we enter an event or venue.

Foreman: A recent ABPCO debate with venues, conference organisers and suppliers highlighted that Wi-Fi is increasingly becoming the lifeblood of events. Provision of Wi-Fi has moved from becoming a “luxury” item to a fundamental utility, in a similar way to light and heating – this is where the venues need to review their provision. Not only do delegates need to access basic communications such as emails and social media, but increasingly Wi-Fi is required for delegates to participate in the conference content, such as voting, Twitter Q&A and downloading applications.

What level of guaranteed service do you believe should be available to organisers, delegates, exhibitors and visitors at an event?

Robson: Simply put, if you need a specific level of connectivity then you should plan for it. It could be a basic level that allows all types of user to collect/reply to email as attending an exhibition or conference is no longer seen as a day out of the office but part of a working day and the expectation is that it will be business as usual. However, anyone requiring guaranteed connectivity (e.g. for download/upload, presentations etc.) should plan for and purchase the appropriate level of service, as the very nature of Wi-Fi means that it is subject to interference and packet loss unless delivered appropriately. It’s the same analogy as relying on a 3G connection from a mobile operator in a busy location – you expect it most of the time but you would choose to use an alternative source of Internet connectivity if your life depended on it.

Foreman: With regard to the provision of free Wi-Fi for conference delegates, which is what ABPCO’s Conference Cloud campaign focuses on, participants at our recent debate agreed that there is a need for “basic” free Wi-Fi. What “basic” constitutes will vary slightly for each venue, but they do need to be clear about what the offer is at that basic level (bandwidth and how many users can access simultaneously etc). The suggestion at our debate was that it should provide access to email and social media, also possibly accessing tools like Dropbox, but that it would be acceptable to charge for a more sophisticated and high bandwidth usage, such as video.

Where would you like to see Wi-Fi available at an event – in the lobby, networking area or within the conference/show?

Robson: There is no reason why it should not be available everywhere including within conference areas. The availability should represent the needs of the event. For example, these days many events are interactive and people tweet constantly during and after seminar sessions and keynotes. On the counter side, some organisers would prefer not to have this distraction during the presentations. Often mobile signals are weak or unavailable, so Wi-Fi should be available to enable other communications such as using an event specific app or Twitter.

Foreman: One of the benefits of providing free Wi-Fi at a venue is to avoid delegates disappearing at intervals to somewhere that does offer it (whether outside in the street as I witnessed in the USA or a local Starbucks). The networking element is hugely important in events, so we would anticipate Wi-Fi being available in networking areas in addition to the main auditorium to participate in applications such as live voting.

To ensure fair access, would you be comfortable to have a third party supplier or the venue manage and control access to Wi-Fi and have the ability to shut down any non-authorised access?

Robson: If shutting down unauthorized activity improves the service and makes for a better experience for all, then yes, third party suppliers and venues should have this control. They will have a much better understanding of Wi-Fi than most event organisers and can use this to ensure that the delegates, exhibitors and visitors all have the required level of service. Education is key; it looks simple, but it isn’t and technology alone cannot guarantee connectivity. Control measures are absolutely essential and third party suppliers and venues should have the power to shut down unauthorised access.

Foreman: I don’t think it is relevant as long as the delegate does not have to pay. The way that venues set up their network is up to them. We would like to see a system in place where either basic Wi-Fi is offered free or the organiser has the ability to fund this basic option (through sponsorship or other methods) with an upgrade on demand.

Can the available technology satisfy the demands?

Robson: Yes it can but it’s not enough to simply provide a network. The Wi-Fi provider needs to work closely with the organiser to work out what those demands are and where the pinch points lie, so that additional infrastructure can be deployed if necessary. In addition to active planning, active management needs to be applied to ensure that rogue networks and rogue devices are shutdown to minimize interference and maximise up time. It’s worth noting that the technology is available to provide acceptable levels of Wi-Fi connectivity but don’t be fooled into thinking that because a venue claims to have a good Wi-Fi network that it’s using the latest technologies or that it is adequate for every event. Event organisers must ask specific questions when choosing a venue about how many people they want to connect concurrently and what sort of experience (i.e. bandwidth) each user can expect, especially in areas where large numbers of people will gather e.g. lobby areas, cafés etc.

Foreman: We learned during our debate that there is a lot of legacy infrastructure in situ at many venues that is not currently equipped to deal with the bandwidth demands. This is a big part of the discussion for many venues, as there is a cost to invest in upgrading their systems to offer greater functionality and service levels to professional conference organisers and their clients. What we explored at our debate was a number of initiatives, highlighted by Cisco, which can assist with cost covering through sponsorship and other marketing initiatives.

Be it a permanent or temporary supply of Wi-Fi, if there is a cost to deliver a robust and accessible service within a venue, who should carry the cost – the venue, an event organiser or the visitor?

Robson: This is a commercial arrangement between the organiser and the venues. This is not about whether the Wi-Fi should be free or not. The hardware, the continual upgrading of the hardware to meet the ever increasing demand and the management of the Internet and the Wi-Fi for each event costs a lot of money and has to be funded. If it’s provided free to visitors then one way or another the event organiser will pay for it. This might be a direct cost; a cost bundled within the price for the space, or a sponsorship of the Wi-Fi perhaps via landing page advert or a video that each user sees when they connect to the Wi-Fi network.

Foreman: As consumers we are increasingly benefitting from high-speed Wi-Fi access on multiple devices and our expectations are changing. Wi-Fi is seen as much more of a basic utility than previously and delegates should not see a separate Wi-Fi charge for logging in to basic access (checking emails, social media etc) when they attend a conference. Whether the venue covers the cost for this basic level in its room hire is up to the venue, but the delegates certainly should not pay. What is required is much greater clarification on what can be offered at a basic level and what will be required for more sophisticated, high-bandwidth usage. We are working on a document highlighting the questions that professional conference organisers need to be asking their clients about their Wi-Fi requirements and what venues need to be clear on. That way we will all have greater transparency and understanding about when there is more to pay for a complex requirement.

What do you see as the next step in the process of attaining solid Wi-Fi connectivity at events?

Robson: New infrastructure in venues that can operate on both the 2.4ghz and the 5ghz bands. More devices in the marketplace capable of operating on 5ghz band and an acceptance from the organiser and the venues that the Wi-Fi has to be actively planned and managed pre and during the event. Also, people need to be pro-active and aware and to keep abreast of technological developments and the impacts they may have.

Foreman: Education and understanding between venues, conference organisers and their clients is the key to moving forward. We are working on an outline document, which will provide organisers with some guidance on what questions they need to be asking. We will also be continuing with our Conference Cloud campaign and encouraging venues to sign up and offer free Wi-Fi to delegates. We have over 130 venue sites listed across the UK already and we receive more requests to join each week.

 

Conclusions:

Both associations agree that Wi-Fi is now a crucial part of any type of event. People depend on being able to connect for both personal and business reasons, thus, venues need to be able to provide that connectivity.

Fundamentally, whatever level of connectivity required by an event organiser must be planned for so that the basic level of service meets expectations. The definition of ‘basic’ will differ, so each venue must be transparent about what exactly is being offered. But what, if any service, should be free? Should a ‘basic’ level of service be free, with the opportunity to then purchase a higher level? Or should all levels of service be purchased to meet the event organisers exact needs?

It seems a unanimous agreement that Wi-Fi should be available anywhere and everywhere at an event venue. The pros to having Wi-Fi available to delegates throughout the venue (ability to participate in interactive seminars, live tweeting, avoiding absconding) outweigh the cons (potential distraction during presentations).

It is acceptable for third party suppliers or venues to be able to manage and control Wi-Fi access, including shut downs, as long as it is to ensure excellent service and delegates are not paying for that service.

The technology is there, but careful planning must be carried out when researching venues with detailed questions being asked about the service level required. While there is the technology to meet specifications, it is not a given that venues will have the necessary systems in place.

The provisions that need to be in place in order to provide Wi-Fi cost a lot of money, and continually have to be updated. It seems that it would not be possible for a venue to completely swallow this cost and offer free Wi-Fi for all. The cost is inevitably knitted into overall costs e.g. room hire or day delegate rate or passed down to the end user. The general consensus is that the delegate should not be paying for it, and either the venue organiser needs to be covering the costs, or a sponsor who utilises the landing page for marketing purposes.

The next steps to attain solid Wi-Fi connectivity at events are; venues operating on both 2ghz and 5ghz bands, proactive planning and management before and after the event from planners and venues, technological education so there is clear understanding between parties, and finding a way to offer delegates free Wi-Fi e.g. through ACBPO’s Conference Cloud campaign.

The Farce of Broadband Advertising and better ‘Wi-Fi’ boxes

Recently there has been a massive increase in the TV, Radio and Online advertisements from Broadband providers saying they’ve got the best Wi-Fi.

Indeed, they might have the most strongest signal they’ve ever had, claim to reach further in your house than they previously did or cover an entire mansion. But they are misleading people significantly into thinking that by swapping broadband provider, they will solve the Wi-Fi issues in their house.

We’ve seen this with a number of clients recently, tricked into changing their provider, and lo and behold, they are still suffering the same issues. They go away thinking that by changing provider, often locking themselves into 18 month contracts, that all their problems will be solved by a shiny new box.

Indeed advertising watchdogs have found that companies such as BT shouldn’t be doing this (click here for the link).

What will it do?
For anyone suffering with Wi-Fi issues, changing your broadband provider will mainly only help if the issue is with your broadband.
There’s already enough confusion over whether it’s your broadband or your Wi-Fi that’s the problem, with many users getting confused by both these terms. The advertising for the broadband industry does nothing to help this.

What’s the problem then?
Often the problem has nothing to do with their broadband, it is more likely to do with the wireless environment that the router sits in.
Wrong placement in the house, people not manually setting up the Wi-Fi from the broadband router, expecting it to be like the adverts and to have a great signal around a property the size of Buckingham Place – it just doesn’t happen.

If the true problem is Wi-Fi, I’m afraid the solution is to fix the Wi-Fi issue at hand. Changing a box for another one with a lot of false marketing promises, that won’t do the trick. But by the time you’re signed into another 18 months, that’s when you’ll realise.

What can I do about it?
There’s lots of advice across this site that explains how to make the Wi-Fi better, and we are pleased to be able to offer this as one of our core services. By using technical industry software, we can provide on-site Wi-Fi Site Surveys that help to diagnose your issues.

Please contact our team by emailing [email protected] or by calling one of our offices.

Access Points: New colours and skins | Advantages

Ubiquiti | New Colour Range and Finishes

Back in the days, Access Points (AP) used to be blunt and boring since you were limited to the white colour only. However, you can forget those days as Ubiquity is going to soon release their new range of colours and skins for the new UniFi nanoHD AP.

The Ubiquiti UniFi nanoHD AP features simultaneous, dual-band, 4×4 MU-MIMO technology and convenient 802.3af PoE compatibility. The compact design delivers a cost-effective combination of value and performance.

There are literally hundreds and hundreds of AC certified devices being used today, and all of them can benefit from the deployment of wave 2 AC access points. The nanoHD AP features the latest in Wi-Fi 802.11ac Wave 2 MU-MIMO technology.

Apart from speed, there are 3 main features that separate wave 2 APs from its wave 1 predecessor:

  • MU-MIMO
  • 4 spatial or data streams
  • 160 MHz channels

What does this mean for your business?

With the right design in place, wave 2 access points can offer better performance using fewer APs, which helps boost productivity, efficiency and user satisfaction rates.

We’ve had lots of clients who asked about having an oak coloured access point, and we’ve always felt sorry to let them know it was not possible. But now thanks to Ubiquiti’s new range of colours and skins, they allow the UniFi nanoHD AP to blend into its surroundings.

Access Points | Better for Businesses

While range extenders are great for home Wi-Fi networks, they’re not efficient for modern businesses. This is because they can only support a limited number of devices at one time, usually no more than 20. While range extenders do increase the coverage of a Wi-Fi router, they do not increase its available bandwidth. Depending on the number of devices you have connected simultaneously, a range extender could end up weighing down your connection.

Access points, on the other hand, can handle over 60 simultaneous connections each. By installing access points throughout the office, users can roam freely from room to room without experiencing network interruptions. As they move through the building, their devices shift seamlessly from one access point to the next without dropping the connection—they will not even realize they are switching between networks.

Advantages of Using Wireless Access Points

When you have both employees and guests connecting with desktops, laptops, mobile phones, and tablets, 20 devices on a wireless network adds up quickly. At 60 simultaneous connections each, access points give you the freedom to scale the number of devices supported on your network. But that’s only one of the advantages of using these network enhancers—consider these points:

  • Business-grade access points can be installed anywhere you can run an Ethernet cable. Newer models are also compatible with Power over Ethernet Plus, or PoE+ (a combination Ethernet and power cord), so there is no need to run a separate power line or install an outlet near the access point.
  • Additional standard features include Captive Portal and Access Control List (ACL) support, so you can limit guest access without compromising network security, as well as easily manage users within your Wi-Fi network.
  • Select access points include a Clustering feature – a single point from which the IT administrator can view, deploy, configure, and secure a Wi-Fi network as a single entity rather than a series of separate access point configurations.

Is 2.4GHz dying? Will 5GHz become a better option?

Do the terms ‘802.11ac’, ‘Wave 2’ and ‘5GHz’ sound familiar? They are often associated with shiny new phones and Access Points. Conversely, ‘2.4GHz’ may invoke images of old barcode scanners and legacy home routers. Is this a fair perception?

It’s been apparent for a couple of years that the 2.4GHz band of Wi-Fi is getting more crowded. Allowing users to share this spectrum at the same time is the thing that made it so useful, but at the moment, the same feature unfortunately starts to make the spectrum unusable in several situations.

In 2016, Apple and Cisco issued a paper in regards to the best network practices for enterprises where they stated that the use of 2.4GHz band is not considered suitable for business and/or mission critical enterprise applications. They also suggested to businesses to change to 5GHz band and replace the 2.4GHz.

In 2014, the Wi-Fi Alliance analysed the Wi-Fi enabled devices in the world, plus the amount of selling and shipping of sales each year. The results showed that the number of new devices is going to continuously grow at a fast pace. Most of the devices sold today can work with both 2.4GHz and 5GHz spectrum, but they are set to default to use 2.4GHz spectrum. The reason behind devices being set as default to using 2.4GHz is to enable usability of these devices on older Wi-Fi routers. This unfortunately leads to creating an increasing demand in only one part of the spectrum. Hence, there is no doubt the bandwidth can get full.

What is the solution that the market has found?

Wi-Fi/802.11 started off in 1997 and it ran exclusively on 2.4GHz. Two years later, in 1999, 802.11a has launched and 5GHz became an alternative. Between 2009 and 2017, as specified above, most devices have been manufactured with 5GHz support. However, this is set to continue with 5GHz-only devices (802.11ac) which is seeing a rapid adoption rate.

Some of the devices like Amazon Alexa, Apple HomeKit, etc. connect to Wi-Fi by exclusively using 2.4GHz. This might be a sign 2.4GHz is not dying. Sadly, non-Wi-Fi equipment interfere on the 2.4GHz frequency and makes it more congested than ever before. For this reason, Wi-Fi moves towards a 5GHz-only future.

What is the difference between 2.4GHz and 5GHz?

Most of the existent devices rely on 2.4GHz connections even though they have 5GHz support. 2.4GHz connection is a shorter, denser frequency which is better for range and in case there are walls between the router and the user. Having numerous devices using the same frequency impacts the overall quality and result in dropped connection occasionally.

Changing to 5GHZ connection results in less interference and there is a stronger signal, meaning a more reliable and constant connection and faster data transfer. The drawback of 5GHz is its shorter range in comparison to 2.4GHz and has more difficulty penetrating obstacles like walls or windows.

To conclude, 2.4GHz has better range but loads of interference while 5GHz has a shorter range with less interference.

The Future

The explosion of IoT has increased the dependency on 2.4GHz and some devices are still produced to connect to 2.4GHz frequency only. Manufacturers are doing this because chipsets are cheaper and often provide better connectivity range compared to 5GHz.

As devices start to focus on supporting both frequencies (2.4GHz and 5GHz) or 5GHz-only, we could see 5GHz becoming the cheaper alternative.

To answer the question of this article, we can safely say 2.4GHz is not dead but will be soon. However, technology needs to continuously find new solutions as the 5GHz spectrum can end up in the same place 2.4GHz did, meaning that if all devices move to using 5GHz, it may also get overcrowded.

For the future, experts advise to make sure you purchase devices that support 5GHz (802.11ac). Also, SDR can improve the operational efficiency and performance of a wireless network, and can also ease the transition to 5GHz-only frequency, so it may be worth investing in.

Li-Fi has been tested in the real world and it’s 100 times faster than Wi-Fi

In a world where technology evolved so much that almost everything needs an internet connection, you might ask yourself whether there will be enough bandwidth for all these devices. Will the existing system be fast enough for all the data? And most importantly, will the data be secure?

Scientists have the answer to all of these questions, through this upcoming technology called Li-Fi (Light Fidelity). This is believed to be the next generation of internet where light will be the medium for transmitting data. Yes, you read that right. The light you use in your house, with some modifications can be used to transmit data to the devices that require internet connection.

Li-Fi was invented by Harald Haas back in 2011, when he demonstrated for the first time that the light from a single flickering LED could transmit far more data than a cellular tower. Li-Fi was tested in labs and achieved speeds of up to 224 Gbps, giving this technology the potential to change everything about the way we use the Internet.

In 2015, scientists have taken Li-Fi out of the lab for the first time, trialing it in Tallinn, Estonia. The reported data transmission speed was clocked at 1 GB per second said to be 100 times faster than current average Wi-Fi speeds.

Li-Fi has also been tested in India this year. Education and Research Network (ERNET) is an autonomous scientific society under the IT Ministry. ERNET conducted a pilot test with Philips India and IIT-Madras at IIT-Madras campus, to gauge the impact and results of Li-Fi. It seems that the tests were successful, and further research is currently underway to make Li-Fi commercially viable. The pilot test was conducted a few weeks ago in controlled environment, and now, the researchers are collaborating with Indian Institute Of Science for further insights.

The technology uses Visible Light Communication (VLC). A medium that uses VLC between 400 and 800 THz. As said above, small impulses switching ON and OFF, like a torch, can be used to write and transmit data in binary code. However, do not worry about a light flickering all the time in an office or in your house, the speed at which the LEDs are switching is imperceptible to the naked eye.

Why do we need a change in the existing technology?

Since the beginning, we have been using Radio Frequency (RF) medium to transmit data wirelessly. RF uses radio waves which have a couple of drawbacks at the moment:

  • High demand for the internet that could not be met by the current method
  • Demand for higher network speed and, therefore, a need for a bigger bandwidth
  • RF medium is not safe to be used in hospitals, power plants, aeroplanes etc. and these places will also need internet connectivity to match the modern era we are in
  • RF is believed not to be safe, since your data can escape through walls and cannot be contained within a particular area

These couple of drawbacks call for a new technology – Let’s welcome Li-Fi. The benefits of Li-Fi, other than the faster speed, is that light cannot pass through walls, hence it makes it more secure, and with less interference between devices.

How does it work?

As mentioned above, Li-Fi uses light to transmit data through special modified LED lights, unlike the Wi-Fi connection that uses RF. As we know, LED is a semiconductor device and like all semiconductors it has switching properties which can be used to transmit data.

Every LED lamp is powered through a driver, this driver will get information from the Internet server and the data will be encoded in the driver. Based on this encoded data, the LED lamp will flicker at a very high speed that cannot be noticed by the human eye. The Photo Detector on the other end will be able to read all the flickering, decoding it after the Amplification and Processing of data. VLC has a frequency between 400 and 800 THz, while radio waves are just 300 GHz.

How far until we will be able to use Li-Fi?

Scientists say that Li-Fi will probably not completely replace Wi-Fi, but rather the two technologies could be used together to achieve more efficient and secure networks. Furthermore, this is also because replacing the existent Wi-Fi infrastructure with Li-Fi is not feasible. However, research teams around the world are exploring how to retrofit the devices we have at the moment to work with Li-Fi technology.

Li-Fi experts are aiming to start installing Li-Fi technology in hospitals and offer a plug-and-play application for secure wireless internet access, with a capacity of 11.5 MB/second (comparable to the first generation of Wi-Fi).

If applications like these and the trial in Estonia prove successful after further observation, we could achieve what Haas outlined back in 2011, namely the beginning of a new internet era.
