Carefully Considering Wi-Fi 6E Versus Private Cellular

This post was originally published on Network Computing

When it comes to expanding the network, organizations have a range of new and compelling options to consider. Two of the most highly hyped options are private cellular (4G/5G) and Wi-Fi 6E.

Wi-Fi 6E is effectively an extension of the existing Wi-Fi 6 (or 802.11ax) standard (which operates in the 2.4 GHz & 5 GHz bands), which is known to improve the overall network performance using technologies such as OFDMA, BSS coloring, target wait times, etc. Thus a big benefit of Wi-Fi 6E is using 6 GHz, which offers 1200 MHz worth of spectrum in the U.S. (Europe is 500 MHz).

This results in 14 – 80 MHz wide channels (or 7 – 160 MHz wide channels). This is more than double what is available in 5 GHz (6 – 80 MHz wide channels). Practically though, most 5 GHz deployments use a maximum of 40 MHz wide channels (12 such channels are possible).

Deploying 6GHz Wi-Fi

Although the density of 6 GHz APs won’t increase as much as when transitioning from 2.4 to 5 GHz, it will still increase due to challenges with signal propagation. To take advantage of the high data rates supported by 6 GHz, you will
