Many people who use walkie-talkies for the first time will have such confusion. What is the difference between the frequency and channel of FRS and GMRS? This article will introduce you in detail to the difference between FRS and GMRS in frequency and channel.

FRS has 22 channels, GMRS has 30 channels, In terms of the number of channels, GMRS has 8 more channels than FRS.
From the chart, we can see that all 22 channel frequencies of FRS are shared with GMRS, and GMRS has 8 more available frequencies than FRS.
For handheld/portable two way radio walkie talkies, among the first 22 channels shared by FRS and GMRS, the 8th to 14th channels, a total of 7 channels, the power of FRS and GMRS are the same, both are 0.5W, and for the 1st to the 7th, and the 15th to 22nd channels, a total of 15 channels, the FRS power is 2W, and the power of the GMRS is 5W, this means that GMRS can bring you greater distances on these frequencies and channels.
As for the GMRS mobile radio, from the 15th to 30th channels, a total of 16 channels can have a high power of 50W, while FRS does not have mobile radio mode.
Among the first 22 channels shared by FRS and GMRS, The bandwidth of FRS is all narrowband 12.5KHz. However, GMRS except for the 8th to 15th channels which are 12.5KHZ narrowband, the rest are 20KHz wideband. This means that from the 1st to the 7th, and from the 15th to the 22nd channel, the GMRS can receive the FRS information clearly, but the FRS cannot clearly receive the GMRS information. Just like walking, GMRS has a wider road to walk than FRS.
The FCC does not allow the use of a repeater on FRS, but it does allow the use of repeaters on the GMRS. Compared to FRS, GMRS has additional channels 23th to 30th, a total of 8 channels, allowing to connect to repeaters. That means if you use a GMRS radio, you can connect to a GMRS repeater through the last 8 channels to get a longer call distance. In the United States, there are many GMRS repeaters shared. For those who like to travel, it is undoubtedly a great benefit.

From the FRS GMRS Frequency Chart and the analysis below, we can see that GMRS includes FRS, and is superior to FRS. I think this is why the FCC named GMRS a licensed radio and needs to pay a fee of 70 US dollars every 10 years. Because compared to the license free FRS radio, GMRS radio can bring you more operation authority and longer call distance.
