"Refarming" is the informal name of a notice and comment rule-making proceeding (PR Docket No. 92-235 http://apps.fcc.gov/ecfs/comment/view?id=107799) opened in 1992 to develop an overall strategy for using the spectrum in the private land mobile radio (PLMR) allocations more efficiently to meet future communications requirements. In June 1995, the Commission adopted a new narrowband channel plan in the PLMR bands below 800 MHz http://apps.fcc.gov/ecfs/comment/view?id=146897.  In February 1997, the Commission adopted a Second Report and Order http://apps.fcc.gov/ecfs/comment/view?id=180426 which did away with 20 discrete radio services and replaced them with two frequency pools: the Public Safety Pool and the Industrial/Business Pool. In May 2001, the Commission adopted the Sixth Memorandum Opinion and Order which resolved all outstanding issues and terminated the proceeding.

 

The rules adopted in the refarming proceeding are applicable to the Private Land Mobile bands below 800 MHz. Specifically, the technical rules adopted affect the licensing and use of radios in the following bands:

 

Figure 4 150-174 MHz VHF high band

 

Figure 5 421-430 MHz available only in Detroit, Buffalo and Cleveland

 

Figure 6 450-470 MHz available nationwide

 

Figure 7 shared with UHF-TV available only in 11 cities
