Industry Colleagues:

Following a presentation I made at a recent broadcast conference in Texas, two people from T-Mobile introduced themselves. They told me that they were investigating the level of activity currently in the 600 MHz band in order to gauge specific challenges as they roll out their new generation of mobile phone technology before the upcoming holiday season.

That’s right — the upcoming holiday season.

T-Mobile will be energizing various counties throughout the continental US (all of the areas in the last T-Mobile email) before the end of this year.  Once they begin testing, wireless operators must cease operation of any device in the affected spectrum.  Radio Active Designs is in communications with T-Mobile Spectrum engineers and will be posting test sites on our web site along with the specific counties throughout the US.

Following is a map that our friends at Professional Wireless Systems have put together that provides details on the counties across the United States that T-Mobile plans on lighting up November 1.

Stay tuned for more information as it becomes available….

Industry Collegues:

As you are aware, there is a 39-month transition period allowed for the 600MHz re-allocation, which began in April. However, wireless microphone and intercom operators should be aware that T-Mobile is pursuing an aggressive rollout plan across the country, with the goal of having several markets offering service before the end of the year.

Just as importantly, T-Mobile is already demonstrating their 600MHz services on a small-scale basis (micro-cells) at press events and trade shows. Recently, at one such recent event, they deployed a low power micro-cell for demonstration (without prior notice) and caused significant interference to wireless microphones and related equipment.

Please look at a recent article that was written by Phil Kurt and appeared in TVNewsTech. In the article he interviews Karl Voss, Chief Frequency Coordinator for every Super Bowl since 1996. The article is enlightening.

Karl has been a long-time advocate of proper frequency coordination. During the interview he notes that even television broadcasters are ill prepared. Needless to say, those of us in the professional audio community have good reason to be concerned about our lack of readiness as well.

Wireless operators should be prepared to vacate the 600 MHz band with the exception of the Duplex Gap and Guard bands immediately. Radio Active Designs is making every effort to obtain T-Mobile roll out information for each region of the country so that wireless operators may prepare. You can find this information on our website, and it is being updated regularly.

Phil Kurt’s full article with Karl Voss is available here.
