Buyer's Guide - License Free Radios
These two-way radios can be used for either commercial or personal use, but without the hassle of needing an FCC license. Yet they're designed to standards found on commercial-grade business 2-way radios. They use either the 900MHz license-free frequencies or the MURS license-free frequencies. And they come with many of the same features as other professional two-way radios.
The radios listed as "900MHz On-Site" typically provide coverage within an area of between 325,000 - 350,000 sq ft and transmit at 1 watt. 900MHZ radios work well indoors but have limited range outdoors.
The MURS radios (Multi-Use Radio Service) use 5 VHF frequencies and transmit at 2 watts. MURS radios typically provide coverage between 3 and 5 miles outdoors (depending on conditions), and 1½ - 2½ miles in urban conditions. Indoors MURS radios are prone to "dead spots" as all VHF radios are. For more information on MURS radios, frequencies, and rules see MURS Radio.
