In the first part of this series, I talked about how the 2.4 GHz band is not very conducive to reliable Wi-Fi. In this part, I will talk about the 5G WiFi’s interference avoidance benefits.
5G WiFi operates in a much cleaner, wider swathe of radio spectrum. 5G WiFi is therefore devoid of any interference from microwave ovens or cordless phones. Besides, the wider spectrum implies that neighboring Wi-Fi networks need not share the air waves as in the 2.4 GHz band. Clearly, the 2.4 GHz pain-points are addressed by 5G WiFi.
Now, 5G WiFi not only works in a different swathe of spectrum, but is also backward compatible with all your other existing Wi-Fi devices that works in 2.4 GHz. So, if your access point and your TV have 5G WiFi, then you get the benefits of this cleaner, wider spectrum. However, if one of your devices does not support 5G WiFi, don’t worry! That device will still work with other 5G WiFi devices in your network. It will, however, not benefit from the 5G WiFi goodness.
In summary, 5G WiFi elegantly addresses the interference problems with current Wi-Fi networks. It is, at the same time, completely interoperable with existing Wi-Fi devices. So, if you are considering an upgrade of your Wi-Fi access point or buying a PC/laptop in the second half of this year, there is only upside in going for a 5G WiFi device. You get blazing speeds, and the cleaner air results in much better coverage & reliability.
