I can tell you we were getting 56kbps 17 years ago and testing 64kps on 25khz ch. I did bandwidth testing with very watchful eyes from govt IT and police officers who wanted to make sure they were getting what they were paying for as /\/\oto was telling them it was vaporware and not physically possible. I left several sites with very impressed customers. Especially after we did the drive tests. On Thu, Sep 7, 2017 at 11:13 AM, John D.
