Service Areas


Prior to the First Report and Order and Eighth Report and Order released December 15, 1995, licenses in the 800 MHz SMR service were issued on a site by site basis. These site-based licenses are referred to as incumbent licenses. Since the introduction of auctions in the service, new licenses are issued on a geographic area basis. Each license consists of a block of frequencies (a group of 800 MHz channels) for a specific geographic area. Geographic area licensees must provide protection to incumbent licensees in accordance with rule 90.683 and rule 90.621(b).
Prior to the Second Report and Order and Second Further Notice of Proposed Rule Making released April 17, 1995, licenses in the 900 MHz SMR service were issued on a site by site basis within Designated Filing Areas (DFA’s) and around DFA’s on a secondary basis (Phase I). Phase I licenses for which applications were filed on or prior to August 9, 1994 are now referred to as incumbent licenses. Since the introduction of auctions in the service, new licenses are issued on a geographic area basis. Each license consists of a block of frequencies (a group of 900 MHz channels) for a specific geographic area. Geographic area licensees must provide protection to incumbent licensees in accordance with rule 90.663 and rule 90.621(b).
 

Incumbent Service Areas

An 800 MHz incumbent licensee’s service area is defined by its originally licensed 40 dBu field strength contour (see rule 90.693). An incumbent licensee may add, remove, or modify transmitter sites within their original 22 dBu filed strength contour (calculated using maximum ERP and actual HAAT) so long as their original 22 dBu field strength contour is not expanded and the station complies with short spacing criteria of rule 90.621(b). Special provisions may apply to some 800 MHz spectrum as discussed in rule 90.693(c).
A 900 MHz incumbent licensee’s service area is defined by its originally licensed 40 dBu field strength contour (see rule 90.667). Incumbent licensees may add, remove or modify facilities within their service areas so long as they do not expand their original 40 dBu field strength contour.
 

800 MHz Basic Economic Areas (BEAs)

To accommodate geographic area licensing and auctions in the 800 MHz SMR services, 175 geographic areas were created. The geographic areas are called Economic Areas (EA’s) and are defined in rule 90.7. These same areas are also referred to as Basic Economic Areas (BEA’s) for licensing purposes. Links to BEA’s are listed below.
