Can My Christmas Lights Affect My Wi-Fi?

The 1st December means we can officially start talking about Christmas! December 1st also happens to be National Christmas Lights Day which coincides with many people choosing to put up their Christmas tree (if they haven’t already done so!).

So you fight the knot of Christmas lights that you’ve fetched from the loft, stick on the ‘Christmas is Coming’ playlist on Spotify (thank us later) and flick the switch for the moment of truth – And Bublé buffers as soon as the tree lights up. What’s going on?

There tends to be articles that circulate this time of year about how Christmas lights could be interfering with your Wi-Fi. But is it really the Christmas tree lights that’s causing Mariah to falter on that high note?

If you haven’t put your tree up yet, and you’re a bit of a Wi-Fi geek (like us) then why not do a little experiment to see exactly how much your Christmas tree lights affect your Wi-Fi? Test your internet and download speeds before and after putting up the Christmas tree with the lights turned on.

 

Will my Wi-Fi be affected by my Christmas tree lights?

Let’s face it, no one wants to choose between functioning Wi-Fi and a Christmassy home. People need that bit of festive cheer more than ever this year, but we also need to know we can rely on our Wi-Fi to keep us connected with our loved ones over the festive period (and stream all the Christmas movies…).

There are potential Wi-Fi issues that can arise with Christmas tree lights so we thought it was worth running through a few do’s and don’ts to help avoid any internet interference from happening in your home. But first – what’s the reason Christmas lights could cause internet issues?

 

How can Christmas tree lights interfere with Wi-FI?

Christmas lights emit a very weak electromagnetic field which can theoretically interfere with the radio waves being transmitted from your router, thus affecting your Wi-Fi speed. If the lights were to transmit electromagnetic radiation at or around the same frequency, then it is possible that they could slow down your Wi-Fi.

Between the LED or lamp being completely on or off, it can exhibit negative resistance which in turn causes radio energy. This happens less with modern day lights than older ones though (see below for more info on this).

Is your tree lit up to give a soft glow, or does it look like something fresh out of Blackpool illuminations? The more lights you have, the stronger the electromagnetic field will be.

And the closer the router is to the lights, the higher the chance of interference.

So what can you do to ensure that your beautifully decorated Christmas tree doesn’t knock off your Netflix binge of Christmas movies?

 

Geekabit’s Top Tips to Prevent Wi-Fi Interference this Festive Season

 

Rule #1 – Don’t place things on top of your router

Just don’t do it. This doesn’t just go for decorations, but in general. We can’t stress this enough – Don’t put anything on top of your router.

This includes Christmas lights – No matter how festive they look! Don’t put Christmas lights or anything else directly on top of, or too close to, your router.

Whilst it has been reported that routers that were placed too close to Christmas tree lights could be negatively affected by signal interference, if they’re not directly next to each other or on top of each other, it should be fine.

 

Rule #2 – Use a main plug socket

We get it – Christmas is one of those times of year when you’re struggling for socket space and digging out all the extension cables you can find to be able to power Christmas tree lights and all kinds of other lit decorations.

But don’t be tempted to unplug the router and plug it into the extension cable. It will work a lot better, and faster, if it’s plugged into a main socket.

 

Rule #3 – The more modern the lights, the better

There are generally 2 types of light whose qualities have the potential to cause interference.

Older types of Christmas lights that are arranged in a string of low voltage lamps in series with each other and are designed to blink can cause radio interference which can lead to dips in Wi-Fi speed.

More modern Christmas lights use solid-state LED’s and have an external control for flashing which don’t create radio noise. However, it’s worth noting that some LED’s have a chip inside the bulb to control the blink and these devices can also cause interference.

On the whole though, modern lights are definitely less likely to cause you a Wi-Fi problem, so maybe save yourself the annual horror of trying to untangle your 10 year old string of lights and treat yourself to some new ones.

 

Rule #4 – Don’t put your router in ‘high traffic’ areas

Tis the season for family gatherings, friend get-togethers and all sorts of festive shenanigans. Not to mention the big man in red tumbling down the chimney! Humans are great signal absorbers, so put the router in a place where it won’t get blocked by partying people or round bellies that shake like jelly.

 

Did you do the Wi-Fi speed test before and after? We’re pretty sure the results will be rather negligible but we’d love to hear your results!

 

Could Pesky Pigeons be Interfering with your Satellite Broadband?

A short while ago we blogged about space entrepreneur Elon Musk’s company Starlink – A new satellite broadband service.

In a recent article from the BBC, a cyber-security expert from The University of Surrey talks about the outages he experiences on his satellite broadband – And how he thinks they could be down to pigeons sitting on his dish!

Those who live in rural areas can only dream of fibre broadband – Satellite broadband gives these people a chance for low latency broadband. This particular cyber expert, Professor Woodward, is one the 100,000 beta testers of the LEO (low Earth orbit) satellite broadband system.

And he believes that his satellite dish looks rather like a modern bird bath – That the pigeons have taken a shining to!

It’s definitely not a bird bath though. This fancy little dish sends and receives signals to passing satellites. There is a constellation of 1,700 satellites at a height of approximately 550km (380 miles). You might have seen them in the night sky! They orbit earth about every 90 minutes.

Starlink plan to mobilise tens of thousands more of these satellite to improve their broadband service. However, Space X, the company who operate Starlink, have been slowed down by chip and liquid oxygen fuel shortages.

Whilst it’s not definitive what is actually causing Prof Woodward glitches, expert opinion says that a pigeon sitting on a Starlink antenna could certainly cause a decrease in performance.

Starlink aren’t the only organisation planning to provide satellite broadband. There are quite a few in the pipeline!

  • Project Kuiper from Amazon has a plan to launch 3,236 satellites
  • Canadian company Telesat are planning to put 298 satellites into orbit
  • The EU are making plans for a ‘mega-constellation’
  • China are making plans for their own satellite network
  • OneWeb – Part funded by the UK taxpayer – already have hardware in space like Starlink, with 288 satellites in space

If you’ve not heard of OneWeb, their focus will be on providing internet to businesses, maritime users and the government. They have a deal with BT, which means there is a strong likelihood that they will also provide consumer broadband to rural areas. It could also mean portable 5G cells for hire.

Some people may even be using satellite broadband without realising it! For places where fibre isn’t available, suppliers may run a satellite link. This would feed the local broadband pipe, giving rural homes a connection.

Becoming a beta tester isn’t cheap

If you’re struggling with a rural broadband connection and are sat wondering how much it might cost to become a Starlink beta tester, then read on.

It currently costs about £500 for all of the equipment you will need, plus £89 per month fees.

Thankfully, it’s pretty straightforward to get it all set up. Starlink will provide you with an app that helps identify any potential obstructions when you’re choosing the best spot for your dish.

You’ll want to choose somewhere flat and easy to get to – But worth considering the pigeons too!

Once you connect to the router and the dish is in prime position, you should find yourselves with fast internet.

What are the actual speeds of satellite broadband?

In this example, the average speeds were 150-200 megabits per second (Mbps) download speeds and 10-20Mbps upload. Whilst there may be occasional dropouts, this scenario didn’t experience interruptions in streaming shows.

And for many people struggling for broadband in rural locations, these speeds are a dream come true.

And with Elon Musk hoping to double the top speeds offered to 300Mbps, there seems to be scope for improvement.

What can affect satellite broadband service?

Well, as the blog title implies, pigeons can be a bit of an issue. But there are also other factors that can affect the service that satellite broadband service users receive via LEO satellites.

  • It depends on whether there are a number of other dishes nearby. For this reason, Starlink limits the number of users per coverage area. In a given area, not very many users can have the top speed at the same time. This is because it has a finite capacity it can provide in a given area, so user experience will decrease as the number of nearby users increases.
  • Regulator Ofcom expressed their concerns about how different satellite systems could cause interference. What would you prefer – A slow but reliable connection, or a fast yet intermittent one? For things like Zoom, you’re going to need a continuous connection.

Will the skies become crowded?

Astronomers have actually already started observing how busy the LEO is becoming, and how trails of satellites are interfering with their observations.

The possibility of collisions is also a very real concern. Apparently there have already been reported near misses involving Starlink satellites, with experts warning that the ability to prevent collisions between the many satellite constellations will become increasingly difficult for both humans and algorithms.

This means we may require more technologically advanced solutions in order to keep spacecraft safe in space.

Of course, the number of satellites orbiting earth will depend on the demand for them. There’s not much point sending all these satellites up into space if there isn’t actually a demand for satellite broadband here on earth!

But for those living in rural areas where fibre broadband isn’t possible, satellite broadband could be just the solution.

Just make sure to watch out for the pigeons!
