Wireless Networks are the preferred choice for IoT connectivity

When it comes to IoT (internet of things) applications, wired connections once held dominance. But it is becoming increasingly evident that the preferred choice for IoT connectivity is wireless networking. 

The wireless connectivity market is expected to continue to grow at a compound annual growth rate of 12.8% in the next 3 years, solidifying the trend of networking solutions becoming increasingly dependent on Wi-Fi or mobile networks. 

Due to the versatility and convenience offered by wireless connectivity, this doesn’t come as much of a surprise. 

Without the limitations of wiring, network devices can be configured, monitored and managed remotely – Even if they’re in a different city, country or continent. 

The benefits of using a wireless connection are indisputable.

What are the primary connectivity options? 

There are 2 primary choices when it comes to wireless connectivity: Wi-Fi and mobile technology. 

Wi-Fi 

  • Operates on the IEEE 802.11 standard
  • Supports multiple protocols including 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac (determining the connection’s speed and range)

Mobile Technologies

  • Have evolved from 3G to 4G to 5G
  • Each defines the connection’s speed and capacity available to users and end devices

RSSI and RSRP

Whether your network device operates on Wi-Fi or mobile technologies, if you’re checking out your network then you’ll likely come across RSSI and RSRP metrics. These metrics are vital for displaying the strength and power of your connection. 

What is RSSI, what does it do and how is it measured? 

  • RSSI stands for Received Signal Strength Indicator. 
  • At the moment radio frequency power and quality reaches the receiver, it’s measured by RSSI. For example, a network device or antenna. 
  • RSSI can be used to gauge the strength of the signal in any wireless system, it’s not exclusive to any one type of wireless technology. 
  • Whether you’re using Wi-Fi or mobile technologies, RSSI can provide signal strength data across different types of radio frequency communications. 
  • This means that RSSI can be a good indicator of whether your network devices have robust connectivity.
  • RSSI signal strength is measured in negative values, with stronger, higher quality signal values being closest to zero.
  • NOTE: RSSI values are not standardised across industries, so bear this in mind when interpreting network data for devices manufactured by different companies. 

What is RSRP? 

  • RSRP stands for Reference Signal Received Power and is measured in negative values.
  • RSRP is particularly relevant for mobile technology network solutions like 4G and 5G.
  • It is a type of RSSI measurement, but used to measure the power of mobile signals spread over full bandwidth and narrowband.
  • RSRP measurements can help you to see your network’s overall signal coverage and capacity across all frequencies used for your networking solutions by measuring across the full bandwidth.
  • The quality of your connection in specific frequency ranges can be assessed by measuring RSRP over a narrowband. This can be used to troubleshoot specific issues that could affect signal quality as well as optimising network performance.
  • By using the RSRP signal strength, you can determine a more precise measurement of the cellular connectivity that your network receiver obtains. Having this information can enable you to make informed decision about your network infrastructure as well as Quality of Service Assessments and further improvements.
  • NOTE: Just as with RSSI, the RSRP signal strength can differ by manufacturer.

Connections Boosted by VMO2 5G Drones for Search and Rescue Missions

Here at Geekabit we talk a lot about the problems that rural areas face when it comes to connectivity – Whether it’s mobile or broadband. 

Mostly we’re talking about businesses and homes that struggle with more traditional forms of broadband internet connectivity as well as mobile broadband options. 

But what about organisations that rely on connectivity outside the normal 4 walls of business premises?

For Search and Rescue teams, staying connected couldn’t be more vital. Yet, they’re often plunged into rural and remote locations trying to find someone missing and potentially hurt. 

So how can we make sure that these Search and Rescue teams stay connected with their base and are able to utilise location data? 

Virgin Media O2 (VMO2) has come up with just the solution. They’ve recently developed a 5G-connected drone that is specifically designed to bolster the communication that is so vital to Search and Rescue teams. 

Who is trialling this 5G drone for Search and Rescue teams? 

The first Search and Rescue team to trial VMO2’s 5G drone is Warwickshire Search and Rescue team.

As we said above, communication in remote and vast terrains is absolutely vital but can be a challenge for Search and Rescue teams. As the work of these teams is so time critical, it’s essential that their effectiveness is unhindered by communication and connectivity problems. 

As a Lowland Rescue Unit, the Warwickshire Search and Rescue team play a vital role in locating vulnerable missing persons alongside the police. 

With a 45% increase in callouts between 2020 and 2022, the demand for their services continues to surge with 65 callouts in 2023 – That’s more than 1 per week. 

How does VMO2’s 5G drone work?

The 5G Technical Trials Team over at VMO2 saw this need for critical connectivity and devised a portable solution that uses a network of low earth orbit (LEO) satellites. The portability and compactness of the tech means that it’s small enough to be integrated into a drone. Ideal for vast, remote spaces. 

This easy-to-deploy drone acts like a flying mobile phone mast, enabling Search and Rescue teams to stay connected via seamless 5G connectivity regardless of their location.

What do VMO2 have to say?

Here at Geekabit we love to see how innovative thinking and technological advancements combine to create fresh ideas and impactful solutions to a whole range of problems. 

Head of Technical Trials for Virgin Media O2, David Owens, says:

“This project is a further example of how fresh-thinking and 5G technologies can be combined to provide real societal benefits.

“The solution has the potential to transform how search and rescue teams operate and respond to life-threatening situations, enabling them to make faster and more decisive decisions. We’re enormously proud that our connectivity will be able to help these teams to save lives.”

What do Warwickshire Search and Rescue make of the 5G drone?

Trustee and Search Technician at Warwickshire Search and Rescue, Steve Brown says: 

“With more and more callouts each year, this drone with mobile connectivity is a powerful tool for our team to understand and assess a situation immediately, saving crucial time in life-threatening situations.

“It means we will always be connected, ensuring seamless communication and efficient coordination throughout our missions. As a result of this, we will connect the unreachable, save lives, and inspire a new era of technological possibilities.”

There’s no doubt that this innovative use of 5G mobile connectivity is a fantastic example of how technology can be used in even the most hard-to-reach places. 

In the UK, someone is reported missing every 90 seconds. The more swiftly that person can be located, the better the outcome. For those that have gone missing in a remote area, a Search and Rescue team that can stay reliably connected will be a huge advantage. 

As Portfolio Holder for Fire & Rescue and Community Safety at Warwickshire County Council, Councillor Andy Crump said: 

“The Warwickshire Search and Rescue team do such vital work for our local community by assisting the police in searching for missing people. 

“This new solution from Virgin Media O2 will help the team on these missions and ultimately save many lives. It is further evidence of the positive impact improved connectivity can have upon our society.”

We’re looking forward to seeing how 5G drones and satellite broadband technology can be accessed in more remote areas and rural locations.

Do You Need a Media Converter for Your Network?

 Networking and Media Converters have gone hand in hand right from the start. They play a vital role when it comes to solving interconnection problems in networks. 

If you oversee a business network (or one in a large home) then you probably already use this handy device. But are you using the media converter correctly? 

What is a media converter?

A media converter is a networking device that allows you to connect one type of communication protocol cable to another different type of cable. For example, connecting a twisted pair to fibre optic cable. 

By connecting two different media, like Ethernet copper and Ethernet fibre, they can typically connect devices that are beyond 100 metres from the nearest available switch. 

The reach of the copper port can be extended with a copper to fibre converter by connecting a copper port on an Ethernet switch to the fibre that connects the device in the remote location.

The ability to do this provides great flexibility when building and connecting networks, easily connecting fibre and copper cables.

A media converter is usually a two-port device equipped with a copper interface on one side and a fibre interface on the other side.

Another key building block within a network are Switches. They enable you to connect multiple devices, such as computers, wireless access points, printers, and servers;  All on the same network within a building or campus. A switch enables connected devices to share information and talk to each other.

Switches are mostly made up of LAN ports which are usually copper Ethernet with a few fibre-based uplink ports. They are also often SFP-based (small form-factor pluggable used for data communication). The copper ports are used to connect devices within a short-range (up to 100 metres) while the SFP uplinks can connect devices that are further away (which would be useful for other switches and/or servers).

The goal for any well-designed network is to use all the available uplinks. This maximises throughput. Oftentimes, spare LAN ports are kept in order to be able to easily connect new devices in the future. However this only works well if the device is within 100 metres from the switch. It can also cause problems if it is in a ‘noisy’ environment – A copper cable can be susceptible to electromagnetic interference. 

In what sort of situation could we see these issues arise?

  • A computer placed in a remote location
  • An access point in an outdoor area
  • A video surveillance camera
  • An access control system far from the last switch, 

For instances where the LAN must be extended over 100 metres, you will require a network extender, and a media converter would be the ideal solution. 

To extend a network to a distant location, you would use a fibre connection from the switch and a media converter to connect to the device.

The remote device problem is solved with the Ethernet link providing a very long reach thus extending the connection. It also saves you from having to add other switches to the network. 

How Does a Media Converter Work?

Media converters can be split into two main groups. 

The first type of media converter can only convert physical media. For example,copper to fibre, or fibre to copper, without adjusting the speed of the link. This type of device is most commonly used when latency is a critical factor, in other words, when a time delay when transmitting the traffic is unacceptable during conversion. 

The second type of media converters are often called switch converters or rate converters. These are a standard Ethernet switch equipped with two ports. These devices can adjust both the media and the link speed so that it is possible to connect a 10/100/1000T port to a 100FX port. For time-sensitive applications, this type is unsuitable as the switch adds a small amount of latency to the connection.

Do media converters work in both directions?

Yes, they can work in both directions. Media converters work with bidirectional links, so the same model can be used to convert copper to fibre but also fibre to copper. 

If you use these devices in pairs, you can use the same model for both ends since they work both ways.

What Are the Different Types of Media Converters?

There are different types of media converter, including:

  • One that connects fibre and copper cables (the most common)
  • One that can convert Ethernet to VDSL 
  • One that can inject Power over Ethernet (PoE)

Typically, media converters are small standalone unmanaged devices. However, they can also form managed and unmanaged chassis solutions to integrate multiple devices within your network in a 19″ standard rack. For deployments in harsher environments, industrial media converters can be mounted in DIN cabinets to protect the electrical components.  

What is the most common model of media converter? 

As we mentioned above, the most common model of media converter is one which connects copper to fibre with one RJ45 port and one fibre port or SFP bay. To allow another converter or a switch equipped with the appropriate interface to be connected easily, the transport protocol is always Ethernet. 

What about legacy infrastructure?

It’s not always possible to use a fibre link due to legacy infrastructure, for example twisted-pair phone cables or co-ax cables. If these are already in use, replacing with new fibre is not practical. Media converters that convert Ethernet to co-ax or Ethernet to twisted-pair allow the use of legacy infrastructure. 

These devices can reach long distances over legacy cables due to using VDSL (Very high Data rate Subscription Line) technology.

As mentioned above, another type of converter can provide Power over Ethernet (PoE) on the copper Ethernet port to power remote devices. This is particularly useful for things like CCTV cameras or access control gates, and helps to simplify deployment of physical security solutions.

Covering the most commonly used interfaces today, media converter port speeds include Fast Ethernet, Gigabit and 10 Gigabit. Transceivers through an SFP port are able to operate on fibres from just a few metres in length up to 120km, satisfying a wide range of distances and speeds.

Media converters are useful for desktops too

Did you know that media converters can be used on the desktop too? 

The USB to fibre Ethernet media converter acts as a Network Interface Card for your desktop or laptop – Quickly deploying a Fibre To The Desk (FTTD) solution for security-sensitive applications, or those more than 100 metres from the switch.

What Are the Features of a Media Converter?

The majority of media converters are not smart devices, however there are some media converters that have smart features that can help to simplify the management of large networks. 

‘Have you turned it off and then on again?’

We’ve all heard that old IT joke. But actually there’s a reason why IT guru’s and network engineers say those notorious words. One of the most common ways to solve computer-related issues is to ‘power-cycle’ the device – Often, simply turning it off and then on again makes the problem disappear. 

For PoE (Power over Ethernet) powered devices, disconnecting the power on the switch port connected to the device having issues will automatically reset it. 

However, most media converters are not managed remotely and thus any that are on a remote site cannot simply turn the power off. In this case, a network engineer (or other person) would have to physically go to the remote site and disconnect and then reconnect the PoE cable. 

Some configurable PoE Media converters enable PoE power to be reset whenever the fibre connection is turned off and on. This ‘smart’ feature would prevent the need for a physical remote site visit by enabling you to control the PoE power via the fibre connection on the switch, resetting the remote device.
