Connecticut Gets Waiver of 800 MHz Co-Channel Separation Rules
Monday, March 23, 2020 | Comments

The FCC granted a waiver to the state of Connecticut to allow it to operate two 800 MHz base stations at less than the required minimum co-channel separation distance (113 kilometers) from a base station, call sign WNIZ788, licensed to Specialized Mobile Radio (SMR) Inc. in New York City.

Last year, Connecticut said it needs an additional channel to supplement capacity in the area of Litchfield County, Connecticut. The state is upgrading its statewide network to a Project 25 (P25) system and “predicted system loading has shown that additional capacity is required to continue to meet the requirements of the user base,” the order said.

Connecticut said it could not identify a channel that would provide additional capacity for its system and still maintain the required 113-kilometer spacing to another co-channel user. Therefore, it sought a waiver to operate two of its base stations on channel 855.8125 MHz at less than 113 kilometers from the co-channel base station of SMR Inc., call sign WNIZ788.

A contour analysis demonstrated that SMR Inc. will receive interference protection equivalent to that provided by application of the short-spacing table. The commission said the public interest will be served by the waiver because it will allow Connecticut to expand the capacity of its system to adequately provide services to citizens during times of extreme emergency.

The full order is here.
