Louisiana Asks to Continue Using 12.5-Kilohertz Channels for 700 MHz System (7/20/12)
The FCC requested comment on a petition for waiver filed by the state of Louisiana to operate the Louisiana Wireless Information Network (LWIN) in the 700 MHz narrowband spectrum using the current 12.5-kilohertz channel efficiency through Dec. 31, 2024. Comments are due Aug. 3.
Louisiana developed LWIN to provide an interoperable public-safety network in the state. LWIN uses 700 MHz spectrum designated for narrowband use by public safety. The system consists of 67,162 users, making it the largest statewide radio system in the country, Louisiana officials said.
Louisiana said that, “the purpose of the 6.25-kilohertz channel mandate is to allow for a more efficient use of the 700 MHz spectrum dedicated to public safety. LWIN is fully built and operational across the state of Louisiana and is already using available spectrum to provide mission-critical voice communications to its first responder community. The cost to build new radio systems for the reconfigured 700 MHz spectrum is cost prohibitive and any new system in Louisiana within the last six years has been built to operate in the VHF and UHF spectrum.”
Other agencies around the country have also questioned the 700 MHz public-safety narrowbanding deadline, currently sent for Jan 1, 2017.
