Migration to Narrowband 12.5 kHz channels has become a reality in the federal government and is now being mandated for FCC licensees by 2013.
Federal Radio has migration plans to support the conversion of your
existing radio systems to be compliant with the NTIA and FCC regulations. Legacy radio repeaters and related mobile/portable
equipment currently operate on 25 kHz wide analog frequencies. The new rules mandate that all government and commercial radio systems in VHF and UHF be
migrated to 12.5kHz narrowband frequencies.
Traditional conversion
is to simply replace the repeater and all off the radios
with narrowband analog equipment. The unfortunate consequence of this
choice is to end up with a radio system with mediocre audio performance
and a nearly 30% reduction in usable voice communications range. This
is due to the fact that voice signal to noise ratio on analog 12.5 kHz
narrowband channels is much worse than experienced on 25 kHz channels. Its a good choice for budget minded low power system operators.
Thankfully the radio
industry has finally addressed this problem with the recent introduction
of digital transmission technology for land mobile radios.
Two technologies have
risen to the forefront.
1) Digital Mobile Radio (DMR) which provides a 2x increase in
capacity at a single site.
2) NXDN Next Generation Digital Network which
provides a 6.25 kHz channel bandwidth allowing two sites to serve the
area. Particularly well suited for urban areas where radio spectrum is
scarce.
Both
digital technologies greatly improve usable range and integrate digital
services.
You have to hear the difference and see the features to fully grasp how this technology will improve your ability to communicate and manage voice and data messages with your workforce.
