Narrowbanding is and FCC required effort to get more communications paths within the existing radio spectrum. This will make the radio spectrum and system more efficient within the existing allocations. Narrowbanding affects al public safety, municipalities, transportation entities, school entities, hospitals, contractors, utility companies, marine terminals, airports, County and State government entities, and others.Traditionally, systems have been employed that operate on channel bandwidths of 25kHz. "Narrowbanding" refers to a requirement by the FCC that by January 1st, 2013, all existing licensees implement equipment designed to operate on channel bandwidths of 12.5kHz or less. What this means is that licensees will need to convert their existing wideband 25kHz system, to narrowband 12.5kHz operation. Any equipment not capable of operating on channels 12.5kHz or less will need to be replaced.
