Also, this smells like some bullshit to me:

I wonder how much the cellcos had to pay in let's-not-call-them-bribes over the past few years, to get permission to start shitting all over the 5.8GHz WiFi band?

Almost seems like the cellcos *really* don't like the idea of unlicensed spectrum that anyone can just flow data through. After all, that's *their* job.

Fell down a Wikipedia rabbithole and boy, does this chart make me feel like I've Seen Some Shit, because I remember all of those transitions. (Mostly I remember having to replace my phone waaay more often than I ever wanted to. And so many model-specific phone chargers.)

But that Motorola Razr did feel like the future.

Any #HamRadio, #telcom or other RF-interested folks want to take a guess as to what this signal might be? I can't figure it out.

Starts at 418.360MHz and is about 13.5MHz wide (ends around 431.880MHz), with a soft peak around 428 where it's about 11dB above the noise floor using an indoor 24" whip.

It's too low for LTE Band 31/72/73 or the 450MHz stuff. Super clean edges.

FCC freq DB just says "CDMA 5,450 UPLINK" from 410-446.5 with no other explanation.

I’m no expert on #telcom hardware, but I find it hard to believe that modern phone switches couldn’t automatically infer the area code if someone dials only 7 digits instead of the full 10. Why make *everyone* do 10-dig dialing all the time? Just assume the dest area code is the same as the origin’s if it’s not included.

This seems like a limitation that should have expired with mechanical switching.
