• NextNav issued a clarification disputing claims that its proposed 5G use of the lower 900 MHz band would interfere with unlicensed security and alarm devices.
• A rooftop test in San Jose placed alarm-system gateways about 20 feet from a high-power 5G antenna, exposing them to signal levels described as stronger than expected in typical use.
• NextNav reported that smoke and carbon monoxide alerts transmitted immediately to a monitoring application, while a panic-button alert sent from the 17th floor reached the rooftop gateway without disruption.
• The company argued the 902-928 MHz band already supports coexistence among multiple unlicensed technologies, with Part 15 devices continuing to operate across the full band under its proposal.
• NextNav framed the plan as enabling a terrestrial, 5G-based positioning, navigation, and timing network intended to complement GPS.
