BrandPost: Is 802.11ax the End of Dual 5 -GHz Radio APs?

There are a lot of things that remain to be seen about how 802.11ax will affect wireless network design. An interesting side effect of the addition of OFDMA to the standard may be an end to the dual 5 GHz access point (AP). In a typical campus wireless network, we don’t need as many 2.4 GHz radios as 5 GHz radios. Rather, we are more limited in the number we can use because the 2.4 GHz spectrum has fewer channels and a larger coverage area. This issue is even more pronounced in high-density wireless deployments.

Rather than just disable the 2.4 GHz radio, some APs allow you to switch the unneeded 2.4 GHz radio to a 5 GHz radio in software. This can be useful because there are a lot more available 5 GHz channels, so rather than having a bunch of APs with only one radio you can add 5 GHz capacity to the network with the same number of APs.
