It's not normally wise for me to comment on public safety spectrum policy issues as they usually generate plenty of heat without my input.  But there is a serious, high stakes policy debate at the moment, and I can't resist.  At the center of that debate is what the country should do with the 10 MHz of 700 MHz spectrum, labeled the D Block that happens to sit right next to another 10 MHz of spectrum that has already been allocated to public safety for broadband purposes.   We also need to remember that this spectrum is particularly well-suited for wireless broadband services, as its propagation characteristics are superior to higher bands such as 1.9 GHz.  Everyone active in the debate recognizes that 700 MHz is beach front spectrum property in a wireless world that is embracing data applications at an unprecedented pace.  MORE
