FCC Proposes More Unlicensed Spectrum

The Federal Communications Commission (FCC) just proposed up to 1200 MHz of spectrum for Wi-Fi use by unlicensed devices. These devices would operate in the 6 GHz band, more specifically 5.925-7.125 GHz.

There are incumbent users of the frequency space but Wi-Fi devices utilizing that frequency, used by Broadcast Auxilary Service and Cable Television Relay Service, would only be used indoor at low power.

Having up to 1200 MHz available for Wi-Fi is great news! It provides more spectrum to a finite resource that we’re beginning to see in the 5 GHz spectrum. With 5 GHz, we are now seeing congestion. We’re limited with the amount of non-overlapping channels. And we’re unable to fully utilize 80 MHz and 160 MHz channel widths.

If Wi-Fi received 1200 MHz worth of spectrum, there would be 59 x 20 MHz channels to select from! Even at wider channels, there will be 14 x 80 MHz channels and 7 x 160 MHz channels.

The industry may be able to see the increase in throughput with more non-overlapping channels at the network operators disposal.

This is a big step forward in the right direction. Wi-Fi needs the frequency space for unlicensed devices and for the industry to innovate further.

CTS 001: We Be Wifi Jammin’

To the tune of $750k. That’s how much the FCC fined Smart City for jamming wifi hotspots at Smart City operated convention centers.

I’m not talking about jamming to some wifi waves.

It appears that some wireless operators don’t understand the consequences of containing wifi networks. In this episode, I talk about the subject of sending de-auth packets to hotspots, what this means for the wireless industry, and whether or not you should care.

  • Smart City
