Wireless Communication Systems

For many two-way radio users, one of the most important benefits of digital is that it can make more efficient use of licensed channels. The airwaves are becoming more and more crowded these days, and the old licensed channel structures are no longer adequate enough to carry the increasing broadcast and radio traffic projected in the future for wireless communication systems.

About Wireless Communication Systems from BearCom

U.S. regulatory agencies are responding to an impending crisis in RF congestion by mandating more efficient use of licensed spectrum. The FCC is requiring producers of wireless communication systems to offer, by 2011, only those devices that operate within 12.5 kHz channels. All users will be required to operate in 12.5 kHz by the year 2013.

Additional Information about Wireless Communication Systems

The next logical step in expanding typical wireless communication systems is to further improve the effective capacity of 12.5 kHz channels. It’s only a matter of time before the ability to consolidate two voice paths into a single 12.5 kHz channel, also known as 6.25 kHz equivalent efficiency, becomes a mandated requirement.

But with digital radio being introduced into our wireless communication systems, there’s no need to wait for a mandate. Devices that incorporate Time-Division Multiple Access (TDMA) can achieve 6.25 kHz equivalency today, greatly increasing their capacity.
