Wireless 4.9 GHz Band Statements
1. Background Information on the 4.9 GHz Public Safety
Band (PSB)
The Federal Communication Commission (FCC) has allocated 50 megahertz
(MHz) of spectrum in the 4940-4990 MHz band (4.9 GHz band) for fixed and mobile
wireless data communications, designating the band for use in support of public safety
(Public Safety Band, PSB). Specifically, the Commission adopted two emission
masks limiting interference potential for the band, one for low power and one for
high-power operations. These changes will allow public safety licensees to leverage
commercial off-the-shelf (COTS) technologies available for the U-NII and ITS
frequency bands. The FCC action allows for a nationwide focus on homeland
security, and will ensure that all state and federal agencies possess the required
communications resources to adequately protect the public.
This allocation will provide public safety users the additional spectrum required
to support broadband applications such as high-speed data transitions and video over
wireless, which in turn enhances local area networks for incident monitoring and
supervision. The spectrum can also be used to support the dispatch operations
communications as well as safety vehicle communications. Public safety agencies
will be able to implement on-scene wireless networks for streaming video, rapid
Internet and database access, and transfers of large files such as maps, building
layouts, medical files, and missing person images. It also allows these agencies to
establish temporary or permanent links to support surveillance operations. This
allocation gives every jurisdiction in the country access to spectrum for deployable,
interoperable, broadband communications.
