Key Differences
FRS (Family Radio Service)
- Designed for casual, short-range communication — the “disposable” walkie-talkie service.
- No license, no exam, no paperwork. Buy a pair of radios and start talking.
- Power is limited to 2 watts, and you cannot replace or upgrade the antenna — it must be the fixed antenna that came with the radio.
- Range is severely limited by these restrictions — realistic range is about 0.5–2 miles in typical terrain.
GMRS (General Mobile Radio Service)
- A step up from FRS — more power, better antennas, and repeater access.
- Requires an FCC license ($35, valid for 10 years, covers your entire immediate family, no exam).
- Up to 50 watts of power on some channels, and you can use external antennas mounted on vehicles or elevated locations.
- Repeater access dramatically extends range — a GMRS repeater on a hilltop can give you 25+ miles of coverage.

How They Differ from CB
CB operates on completely different frequencies (HF band near 27 MHz), uses different modulation (AM or SSB), and has a distinct culture rooted in trucking and rural communication. CB has no license requirement but is limited to 4 watts AM.
How They Differ from Amateur Radio
Amateur radio offers vastly more power, frequencies, modes, and capabilities — but requires passing an examination and obtaining an individual license. Hams can experiment, build equipment, and communicate worldwide. FRS and GMRS are appliance-level services — you use them as-is without modification.
