Seeing is Believing: Demonstrating 5G and Security/Alarm System Coexistence in the Lower 900 MHz Band
There have been concerns within the security and alarm industries that NextNav’s plan to use the lower 900 MHz band for 5G would interfere with devices like smoke detectors and panic buttons.
Seeing Is Believing: NextNav Demonstrates 5G and RFID Coexistence in the Lower 900 MHz Band
On May 4, 2026, NextNav engineers ascended to the roof of 10 South Almaden Boulevard in San Jose (CA) to conduct a real-world coexistence demonstration using the company’s 5G PNT Network and a standard RFID reader with multiple RFID tags. The goal was straightforward: to put recent claims about RFID interference to the test and use a real-world demonstration to lower the temperature of this discussion. For months, some in the RFID industry have claimed that NextNav’s proposal to enable 5G-powered 3D PNT in the lower 900 MHz band would disrupt RFID devices and impose billions of dollars in c
