Wi-Fi uses high frequency radio waves that can be more easily blocked than lower frequency mobile phone signals.
Wi-Fi uses radio frequency waves to transit data back and forth from your device to our router. These radio waves are similar to the ones that your mobile phone uses, or FM/DAB radio. However Wi-Fi uses much high frequencies. Getting more technical, it uses the 2.4GHz and 5GHz range of frequencies. These frequency bands allow for much greater bandwidths (speeds), but as they are higher frequencies than your FM/DAB radio uses (around 0.1GHz/0.2GHz) or mobile phones (0.9Ghz-3GHz), the signals can be blocked more easily by obstructions such as walls, ceilings, and other building materials and furnishings.
Giganet's routers are dual-band and operate band steering to offer best performance to your device
Giganet's UltraHub router is a dual band router, which means that it operates on 2GHz and 5GHz at the same time. It can serve devices on each band simultaneously.
The router also has a feature enabled called band-steering. This technology is where the router will attempt to ensure that your Wi-Fi laptop/phone/device connects to the much faster 5GHz band in preference to the 2GHz band, if your device supports 5GHz. It will only attempt to 'steer; your connection to the 5GHz band if you have a suitable high signal strength, as if not, you will end up on the slower but wider coverage 2GHz band.
These features all happen behind the scenes in the default router configuration to try and ensure that your Wi-Fi devices all get the best performance given their signal strength and capabilities.
5GHz Wi-Fi band offers the fastest speed, but doesn't travel as far as the slower 2GHz band
The 5GHz Wi-Fi band is where all the major speed improvements are coming from. There is a lot more spectrum (radio frequency space) that can be used in the 5GHz band, and this permits much larger channel widths to be used. This offers greater bandwidths or speeds over the connection to each device.
The downside however to 5GHz is that the signals are more easily blocked by obstructions such as walls, floors, ceilings, furniture, and other large building materials and furniture.
This results in you being able to get great performance on the 5GHz band if you are near the router, however if you are the other side of the house, then you may not even be able to pick up a 5GHz signal, and may have to rely on the slower 2GHz band which is better at penetrating objects.
Band steering as we have explained above, helps to move your Wi-Fi device onto the 2GHz band if your signal strength is not great enough to benefit from the 5GHz band. This will have the effect of keeping your Wi-Fi device connected to Wi-Fi, but you may notice a drop off in performance.
Best Wi-Fi router positioning
- Please your router at chest height, ideally on a table or window sill.
- Place the router on its stand with the front pointing to the direction where most of your Wi-Fi users will be connecting from.
- Do not place the router on the floor. This is too low down, and much of the WiFi signal performance will be lost into the floor.
- Do not place the Wi-Fi router near any large metal objects such as radiators, TVs, white goods (fridges/ovens/microwaves), and certainly do not place behind the TV!
- Do not place the Wi-Fi router near any sources of potential interference such as microwave ovens, baby monitors, DECT cordless phones.
We appreciate that the exact Wi-Fi router positioning will be limited by the location of where the fibre service comes into your home, including the ONT, and also where you have a power socket for the router.
