NextNav Inc. has submitted a comprehensive study to the Federal Communications Commission (FCC) confirming that 5G operations can successfully coexist with unlicensed devices in the Lower 900 MHz band. The study provides a real-world deployment comparison and in-depth technical assessments. It concludes that replacing legacy operations with 5G would not cause unacceptable interference to Part 15 devices.
The analysis, led by Dr. John Kim, Vice President of Technology Development, examined five key unlicensed technologies: LoRaWAN, RAIN RFID, Wi-Fi HaLow, Wi-SUN, and Z-Wave. These devices are designed for shared spectrum environments and are built with resilience and adaptability. NextNav's proposed technical rules support coexistence with various users while enabling terrestrial PNT.
NextNav also announced it has retained a testing firm to conduct joint testing with Lower 900 MHz railroad licensees. Discussions are underway with toll operators to evaluate coexistence scenarios through joint testing. These actions reinforce NextNav’s commitment to protecting co-primary licensed tolling, rail operations, and Federal systems in the band.
