PART 90—PRIVATE LAND MOBILE RADIO SERVICES
Technical Summary
Part 90 covers land mobile radio systems used for mission-critical communication in public safety, business, and industrial sectors. It specifies technical standards for frequency bands like VHF (30–300 MHz), UHF (300–3000 MHz), and 700/800 MHz, setting power limits and emission requirements to avoid interference. Frequency coordination is essential for new systems to prevent conflicts, while rules govern modulation, antenna usage, and co-channel separation.
Legal Details
Kama Thuo, PLLC Wireless Telecommunications Law Firm has compiled legal details on FCC Part 90 (PLMRS).
In 2020, the FCC repurposed the 5895–5925 MHz Dedicated Short-Range Communications Services (DSRCS) band for Cellular Vehicle-to-Everything (C-V2X) technology. The upper portion 5850-5895 MHz was allocated for U-NII-4 (unlicensed Wi-Fi in the 5 GHz band).
C-V2X is used in the US, China, and is expected to be used in Europe in the future. It is an alternative to 802.11p, which is the IEEE standard for V2V communications. C-V2X can function without a network and has a range that's greater than DSRC.
| Band Portion | License Type | License Eligibility |
