group held a comprehensive, independent trial of location

3 Communications Safety, Reliability and Interoperability Council Trials ( CSRIC ) In 4Q12 the FCC s CSRIC advisory group held a comprehensive, independent trial of location technologies for indoor E911 in the San Francisco / Silicon Valley area. Joint effort by Public Safety, technology vendors and national wireless carriers.

11 In Conclusion Unlicensed devices interfere with each other constantly, but are designed to frequency hop and avoid interference when they see it Progeny uses only a small fraction (4 MHz) of spectrum and designed its network to reduce interference potential by one-way operation and 10-20% duty cycle (FCC waiver to reduce potential interference) FCC has required live field testing for 18 months and two separate public comment periods for consideration. Progeny has successfully co-existed with all manner of unlicensed equipment for over 3 years in Progeny/NextNav s Bay Area network Testing proves Progeny/NextNav s E911 location service does not cause unacceptable interference to unlicensed devices. Vast majority of unlicensed devices never even detect Progeny/NextNav operations. 11
