The General Mobile Radio Service, or GMRS radios are intended for personal use in general communications. A license is required, but covers an entire family for an entire decade. While it shares some channels with FRS, it offers more power, range and versatility than lower wattage FRS radios, and with fewer limitations. GMRS radios are available in portable handheld models at up to 5 watts and mobile/base station models at up to 50 watts of power. The GMRS also allows the use of external antennas and repeaters for even greater range.
