Study Confirms Win-Win for 5G Operations and Unlicensed Technologies in Lower 900 MHz Band
NextNav (Nasdaq: NN) has submitted a comprehensive study to the FCC demonstrating that 5G operations can successfully coexist with unlicensed devices in the Lower 900 MHz band. The 66-page study reveals that 5G deployment would not cause unacceptable interference to Part 15 devices.
Key findings from the study conducted in San Francisco show that:
- 5G would produce lower emissions than NextNav's authorized legacy M-LMS location service
- The Lower 900 MHz band is dominated by intra- and inter-Part 15 contention, with 5G's contribution being negligible
- Indoor unlicensed signals are significantly stronger than 5G operations in most locations
The study analyzed five unlicensed technologies: LoRaWAN, RAIN RFID, Wi-Fi HaLow, Wi-SUN, and Z-Wave. NextNav has also retained a testing firm for joint testing with railroad licensees and is in discussions with toll operators to evaluate coexistence scenarios.

Lo studio di 66 pagine rivela che il dispiegamento del 5G non causerebbe interferenze inaccettabili ai dispositivi di Parte 15.
I risultati chiave dello studio condotto a San Francisco mostrano che:
- Il 5G produrrebbe emissioni inferiori rispetto al servizio di localizzazione M-LMS autorizzato di NextNav
- La banda inferiore dei 900 MHz è dominata da contendenti intra- e inter-Part 15, con il contributo del 5G che risulta trascurabile
- I segnali non autorizzati interni sono significativamente più forti delle operazioni 5G nella maggior parte delle posizioni
Lo studio ha analizzato cinque tecnologie non autorizzate: LoRaWAN, RAIN RFID, Wi-Fi HaLow, Wi-SUN e Z-Wave. NextNav ha anche ingaggiato una società di testing per test congiunti con i titolari di licenze ferroviarie ed è in discussione con gli operatori di pedaggi per valutare scenari di coesistenza.

넥스트내브 (Nasdaq: NN)은 FCC에 5G 운영이 900MHz 하단 대역에서 비면허 장치와 성공적으로 공존할 수 있음을 보여주는 포괄적인 연구를 제출했습니다. 66페이지 분량의 연구는 5G 배치가 15부 장치에 대해 용납할 수 없는 간섭을 일으키지 않을 것임을 밝혔습니다.
샌프란시스코에서 실시된 연구의 주요 결과는 다음과 같습니다:
- 5G는 넥스트내브의 승인된 M-LMS 위치 서비스보다 낮은 배출량을 생성할 것입니다
- 900MHz 하단 대역은 15부 간섭으로 지배되며, 5G의 기여는 미미합니다
- 실내 비면허 신호는 대부분의 위치에서 5G 운영보다 훨씬 강합니다
이 연구는 LoRaWAN, RAIN RFID, Wi-Fi HaLow, Wi-SUN 및 Z-Wave의 다섯 가지 비면허 기술을 분석했습니다. 넥스트내브는 또한 철도 면허자와의 공동 테스트를 위해 테스트 회사를 보유하고 있으며, 공존 시나리오를 평가하기 위해 통행료 운영자와 논의 중입니다.

NextNav (Nasdaq: NN) hat der FCC eine umfassende Studie vorgelegt, die zeigt, dass 5G-Betrieb erfolgreich mit nicht lizenzierten Geräten im unteren 900-MHz-Band koexistieren kann. Die 66-seitige Studie zeigt, dass der Einsatz von 5G keine inakzeptablen Störungen für Geräte der Teil 15 verursachen würde.
Wichtige Ergebnisse aus der in San Francisco durchgeführten Studie zeigen, dass:
- 5G niedrigere Emissionen als der genehmigte M-LMS-Standortdienst von NextNav erzeugen würde
- Das untere 900-MHz-Band wird von intra- und inter-Part-15-Konkurrenz dominiert, wobei der Beitrag von 5G vernachlässigbar ist
- Innere nicht lizenzierte Signale sind an den meisten Standorten deutlich stärker als 5G-Betrieb
Die Studie analysierte fünf nicht lizenzierte Technologien: LoRaWAN, RAIN RFID, Wi-Fi HaLow, Wi-SUN und Z-Wave. NextNav hat auch ein Testunternehmen beauftragt, um gemeinsame Tests mit Eisenbahnlizenznehmern durchzuführen, und ist in Gesprächen mit Mautbetreibern, um Koexistenzszenarien zu bewerten.
- Study confirms 5G operations compatibility with existing technologies
- Lower emissions than current legacy services in San Francisco
- Minimal interference impact on indoor operations
- None.
Extensive Technical Analysis Demonstrates NextNav’s Proposal for 5G-Powered PNT Supports Coexistence With Unlicensed Devices While Advancing Critical Terrestrial Backup and Complement to GPS
RESTON, Va., Feb. 28, 2025 (GLOBE NEWSWIRE) -- NextNav (Nasdaq: NN) 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 that find coexistence is feasible and replacement of legacy operations in the band with 5G would not cause unacceptable interference to Part 15 devices.
“From the outset, NextNav has been committed to ensuring this proceeding is guided by sound, fact-based, and engineering-driven decisions,” said Dr. John Kim, Vice President of Technology Development. “That commitment shaped our detailed examination of how current unlicensed devices operate in the band. Our findings demonstrate that by updating decades-old rules, the FCC can address a major national security and public safety threat without causing unacceptable interference to unlicensed devices.”
Key Findings Include:
- 5G Does Not Materially Change the Emissions Landscape in the 902-928 MHz Band: The 66-page study confirms that unlicensed devices, which already coexist with other unlicensed operations along with licensed services in the Lower 900 MHz band, can continue to do so under the FCC’s adoption of NextNav’s 5G PNT proposal.
- No unacceptable interference with unlicensed devices. The study found that in the San Francisco downtown area 5G would produce lower emissions than NextNav’s already authorized legacy M-LMS location service. It also found that the Lower 900 MHz band is dominated by intra- and inter-Part 15 contention, and 5G’s contribution is negligible in comparison.
- Indoor signal strength confirms minimal impact from 5G deployment: Analysis shows that unlicensed signals indoors are significantly stronger than 5G operations in nearly all locations. The incremental effect of 5G indoor operations will be well within the capacity of unlicensed devices to manage.
Dr. Kim and his coauthors analyzed five key unlicensed technologies: LoRaWAN, RAIN RFID, Wi-Fi HaLow, Wi-SUN, and Z-Wave. Designed to operate in a complex shared spectrum environment, these Part 15 devices are built with resilience and adaptability at their core, enabling coexistence with NextNav’s proposal for terrestrial PNT powered by 5G.
“The Lower 900 MHz band is a spectrum band that was designed to be shared,” said Renee Gregory, Vice President of Regulatory Affairs. “NextNav’s proposed technical rules support coexistence with a variety of users while enabling terrestrial PNT as part of a system-of-systems approach to complement and back up GPS.”
Additionally, NextNav announced that it has retained a testing firm to conduct joint testing with Lower 900 MHz railroad licensees. The company is also in discussions with toll operators to evaluate coexistence scenarios through joint testing. Finally, NextNav retained independent firms to conduct engineering studies to ensure that all primary Federal systems in the band remain protected from harmful interference. These announcements reinforce NextNav’s commitment to protecting co-primary licensed tolling, rail operations, as well as Federal systems in the band.
