Borrowing from my smart friend Doug Dawson as he writes about cellular fixed wireless access (FWA) networks. The super quick version is that cellular FWA broadband speeds degrade much like the old DSL technology does. The farther you are from the tower, the greater degradation. The FCC doesn’t reflect the degradation accurately, which could have a unintended consequences when maps are used to distribute federal funding…

The map below shows a lot of speed tests from Verizon tower in a suburban county. The yellow dots on the map are the locations of actual speed tests. The colored circles on the map show the distance from a cell tower – with purple showing locations within a mile of the tower, red showing locations between 1 and 2 miles, blue/greed showing speed tests within 2 and 3 miles, and the surrounding white areas at more than 3 miles. I didn’t cherry-pick this particular tower as the best example – there are more than a dozen other Verizon towers in the same county that show similar speed test results. I must note that speed tests are not a prefect indicator of broadband performance, and there might be explanations behind some of the slower readings. But I have to think that seeing this same speed pattern around multiple tower sites is a good indication that this is how the technology works.

This map demonstrates what the farmer told me to a tee. There are some locations close to the tower getting 300 Mbps. Customers just over a mile from the tower are getting slower speeds, with the highlighted ones around 75 Mbps. By the third mile band, speeds have dropped a lot closer to 25 Mbps download, and outside the three-mile circle, speeds drop significantly. There is no easy way to tell if the customers with slower speeds are buying FWA wireless, which uses the spectrum that Verizon labels as 5G, or the older Verizon hotspots that use traditional LTE spectrum.

On the FCC map in this county, Verizon reports two speeds – 300 Mbps or 50 Mbps. It’s not easy to understand how Verizon makes the distinction, but it seems like locations for a fairly good distance around towers are claimed at 300 Mbps.

Somebody who doesn’t understand the FCC mapping rules might think that Verizon is breaking the rules by reporting 300 Mbps speeds in places where actual speeds are a lot lower. But the FCC allows ISPs to report marketing speeds for the FCC maps as long as Verizon is advertising the claimed speeds. But that doesn’t mean that the Verizon FCC reporting is ethical. Customers who might refer to the FCC map when looking for an ISP, or customers that see Verizon advertising are hoping to get something close to the 300 Mbps speed – and many will not.

I have some major concerns about cellular FWA technology related to the upcoming BEAD grants. First, any state broadband grant offices that accept the claimed Verizon speeds in the FCC mapping might not award any grants where a fast FWA speed is claimed. That would be a travesty if folks who can’t get speeds of at least 100/20 Mbps with FWA are denied another broadband option.
