Frequency Coordination Critical in Licensing Interstitial Channels, says LMCC
Expansion of technology options adds complexity to frequency assignment process
Herndon, VA – In its May 26, 2015, filing before the Federal Communications Commission (FCC), the Land Mobile Communications Council (LMCC) submitted for the FCC’s and the industry’s consumption a matrix specifying derated interference contours for all known combinations of adjacent channel system types to be used by participating 800 Mhz frequency advisory committees when coordinating full power, interstitial 12.5 kHz chanExnels in the 809-817/854-862 MHz band (800 MHz Mid-Band). The matrix and the Reply Comments, filed in response to a Notice of Proposed Rulemaking, emphasize the critical role frequency coordination will play in the licensing of interstitial channels.
“The primary goal of the coordination process described by the LMCC is to protect the operations of existing 25 kHz licensees. At the same time, there is an opportunity for more intensive use of the adjacent interstitial, 12.5 kHz-wide channels. Although LMCC’s proposal will add complexity to the frequency coordination process, the LMCC welcomes this if it means making available more spectrum, a scarce commodity, while protecting current users” said LMCC President Greg Kunkle.
The membership of the LMCC, which includes organizations that represent the majority of the users, providers and manufacturers of land mobile radio systems, spent considerable time creating a technically precise guide for certifying 800 MHz interstitial channels.
