Do all walkie-talkies use the same frequency?

Firstly, the radios need to be ones that use the same basic frequency band . Most “business” or “consumer” walkie-talkies will work on either the UHF band (400 – 470MHz) or the VHF band (136 – 174MHz).

Two-way radio works between the frequencies of 30 MHz (Megahertz) and 1000 MHz, also known as 1 GHz (Gigahertz) . This range of two-way frequencies is divided into two categories: Very High Frequency (VHF) – Range between 30 MHz and 300 MHz. Ultra-High Frequency (UHF) – Range between 300 MHz and 1 GHz.

VHF walkie talkies The VHF radios operate at 136-174 MHz and operate over large distances with less power consumption. With VHF walkie talkies, the signal waves can travel a further distance. With optimum conditions (clear view – for example, without buildings and mountains), the range is at its best.

Two-way radios (or walkie-talkies) generally operate in the 136 MHz to 900 MHz frequency range, as defined by the FCC.
