WASHINGTON-The Land Mobile Communications Council has set up new criteria for monitoring interference in the shared business pools.
“It is something we need to do to make sure the spectrum environment doesn’t get gummed up … You have to be a good spectrum neighbor,” said LMCC Secretary Mark Crosby. Crosby also is president of the Industrial Telecommunications Association.
The new system will implement Level 1 monitoring, which uses the repeater’s receiver to monitor signals coming from a co-channel licensee and would serve to disable the repeater transmitter during the co-channel unit’s transmission. Frequency advisory committees will certify that all new licensees have at least this capability.
Also available is Level 2 monitoring, which combats geographic interference problems. An FAC may require Level 2 monitoring capabilities before certifying an application “within heavily encumbered or unique geographic regions,” said an Oct. 16 LMCC letter signed by Paul B. Najarian.
Two LMCC members, the American Trucking Association and the American Mobile Telecommunications Association did not sign onto the LMCC letter to the Federal Communications Commission about the changes. AMTA President Alan Shark said there was not enough criteria for requiring Level 2 monitoring. “It was too ambiguous as to when you go from Level 1 to Level 2,” he said. ATA did not respond to numerous phone inquiries.
