VHF (150-174 MHz) and UHF (450-512 MHz) bands to be on 12.5 kHz bandwidth by January 1, 2013
In order to achieve more efficiency in the utilization of radio frequency spectrum, the FCC has mandated Narrowbanding. Licensees in the private land mobile VHF and UHF bands traditionally have employed systems that operate on channel bandwidths of 25 kHz. “Narrowbanding” refers to a requirement by the FCC that — on or before January 1, 2013 — all existing licensees implement equipment designed to operate on channel bandwidths of 12.5 kHz or less or that meets a specific efficiency standard.
What this means is that licensees will need to convert their existing wideband (25 kHz) systems to narrowband (12.5 kHz) operation. Any equipment that is not capable of operating on channels of 12.5 kHz or less will need to be replaced.
Narrowbanding is not optional. Licensees cannot simply ignore the FCC’s narrowbanding rules. If you are licensed in the VHF and/or UHF land mobile bands and not currently operating on narrowband (12.5 kHz) equipment, you will be affected. Your existing wideband system will need to be modified or replaced by January 1, 2013, and failure to comply may result in serious consequences.
2013 may seem a long ways away, but if you need to replace your equipment, you have less than two budget cycles remaining. The FCC licensing process is also backlogged due to the massive number of license modifications it is processing. Do not delay and risk losing your FCC license or be subjected to heavy monetary fines. Contact a representative at Action Communications. We are ready to help and will guide you through the narrowbanding process.
