Narrowband

Technical Summary

The rules governing the 700 MHz Public Safety Band (763-775 and 793-805) can be found under Part 90, Subparts R and AA. The Band is divided into three segments Broadband, Guard Band and Narrowband. The 763-768/793-798 MHz segment is allocated for public safety broadband communications. The 768-769/798-799 MHz segment is reserved as a guard band. The 769-775/799-805 MHz segment is allocated for narrowband operations. In the narrowband segment, the rules allow the licensing of the 700 MHz General Use Narrowband Channels and Narrowband Low Power Channels for assignment to public safety eligibles, subject to Commission approved regional planning committee (RPC) regional plans. The Narrowband Low Power Itinerant Channels are licensed for nationwide itinerant operation and are not subject to regional planning or frequency coordination.

Table 1. 700 MHz Narrowband Channels
Channel Name Description
 
General Use Narrowband All narrowband channels established in the four narrow band segments other than the narrowband interoperability channels, narrowband reserve channels, narrowband low power itinerant channels, and narrowband state channels are considered general use narrowband channels. See Rule 90.531(b)(6)
Narrowband Low Power These narrowband channels are designated for low power use for on-scene incident response purposes using mobiles and portables. See Rule 90.531(b)(3)
Narrowband Low Power Itinerant These narrowband low power itinerant channels are designated for low power use for on-scene incident response purposes using mobiles and portables. See Rule 90.531(b)(4)

The two narrowband segments are 769-775 MHz (Channels 1 960) for base operations and 799-805 MHz (Channels 961-1920) for mobile operations. Each narrowband segment is divided into 960 channels, with each channel having a size of 6.25 kHz.

Applications for the 700 MHz Public Safety General Use channels must be reviewed and approved by the appropriate RPC within the area of proposed operation, prior to submission to a FCC certified public safety frequency coordinator. For more information on how to apply for and obtain RPC approval for 700 MHz General Use spectrum, contact the RPC in your area.
