FRS vs GMRS

GMRS and FRS are the two main "similar" handheld radio types in the United States. If you're trying to choose between GMRS or FRS radios, here we'll show you the differences between them and help you decide which is the better choice for you.

Definition

Family Radio Service (FRS), which is designed for individuals in close proximity, is easy to purchase at a relatively inexpensive price. However, you may find that FRS radios have a very limited range. This is because the FRS system is only allowed to use 0.5 watts of power according to FCC standards.

It was developed primarily for consumer use, thanks in large part to Radio Shack, who saw the need to define and reserve special radio frequencies for consumers that were separate from other bandwidths reserved for other types of communications. While walkie-talkies have become increasingly popular with civilians since World War II, by the 1990s there was also increasing competition for radio frequencies.

GMRS, General Mobile Radio Service, a more powerful type of primary two-way radio in the U.S. GMRS radios use specific frequencies within the same band designated for FRS radios: 462-467 MHz Unlike FRS, GMRS radios have designated channels within those frequencies that are not available to FRS radios GMRS can be modified to 50 watts of power (although generally we only use 1 watt of power). GMRS can be modified to 50 watts of power (although generally we only use 1-5 watt GMRS) and capture stronger, longer range signals.GMRS radios also require a license from the FCC to operate.

Differences between FRS and GMRS

Types

FRS radios are limited to portable handheld models. In addition, mobile station and base station GMRS units are not allowed to transmit on channels 8-14 cycles and can only receive on those channels. As a result, some GMRS radio manufacturers omit these channels altogether on their mobile/base station units.

Power

FRS radios allow a maximum of 2 watts on channels 1-7 and 15-22, while GMRS allows a maximum of 5 watts on channels 1-7 and 50 watts on channels 15-22.

Removable Antenna

FRS radios must have permanently fixed antennas; GMRS radios are allowed to not only have removable antennas, but can also connect to antennas remotely mounted on vehicles, buildings, or towers as long as they are within certain height limits.

Repeater functionality

While both services share the same 22 channels and frequency assignments, GMRS also has 8 additional repeater channels available, for a total of 30 channels. frs does not have these repeater channels and is not permitted to transmit over a repeater system.

FCC Certification

In order to be considered an FRS or GMRS radio, it must be of a Part 95 type accepted by the FCC for that particular service. If its type meets the requirements of Part 95B, it is an FRS radio. If its type is accepted under Part 95E, it is a GMRS radio.

How do I choose?

Both FRS and GMRS radios use FM instead of AM. GMRS radios will sound louder and clearer than FRS radios. This won't be a problem for most people because quality FRS radios already have great sound due to the excellent build and FM input. If you're picky about sound quality, the GMRS will provide you with extra crispness and clarity. This is because GMRS has more power to support its modulation frequencies, which means less interference.

For those who plan to occasionally use two-way radios in close quarters or less technical outdoor scenarios, FRS radios will suffice.FRS two-way radios have a power coverage range of up to a mile or two (depending on the terrain) and will keep you in touch with your team in case of an emergency.

If you plan to use your two-way radio more frequently over a wider area or in an area with more competitive signals, you may need the increased flexibility and power offered by GMRS radios. If you want the clearest picture of how to use the radio and the most options at what distance, then GMRS will give you more peace of mind. A casual or new two-way radio user, however, will be fine with a high-quality FRS radio.
