The advantage of licensed handheld walkie talkies compared with the cheaper unlicensed types are ‘power & privacy’.
Licensed walkie talkies typically produce a transmit RF power of 5 watts. This compares to 0.5 watts for cheaper license free walkie talkies. That is 10 times the transmit power, which means greater walkie talkie range for the user.
Also licensed walkie talkies operate on business radio frequencies rather than the free unlicensed frequencies available to the general public. This reduces the chance of interference from other users such as children.
