Ultimately, it’s the FCC that has the final say-so on what parts of the spectrum band a wireless carrier can use. Obviously, wireless carriers want as much as they can get to serve as many customers as posisble.
The FCC has officially allowed AT&T to use a portion of the 2.3GHz spectrum.
Some of you may be thinking, “Gee.. that’s awful close to 2.4GHz. Will this affect my Wi-Fi router?” No. The application of the spectrum is totally different compared to your Wi-Fi router, so that’s nothing you need to worry about.
The entire reason why it’s taken this long for AT&T to get approved to use part of the 2.3GHz spectrum is directly because of Sirius XM satellite radio. AT&T had to work closely with Sirius to make sure neither service would interrupt each other. They were able to hammer out and agreement about what could and could not be used, and now wireless broadband can coexist along with Sirium XM radio on the 2.3GHz band.
Yes, this is progress.
