9. The personal walkie-talkie has become popular also because of the U.S. Family Radio Service (FRS) and similar license-free services (such as Europe’s PMR446 and Australia’s UHF CB) in other countries. So, while FRS walkie-talkies are also sometimes used as toys .because mass-production makes them low cost. They have proper superheterodyne receivers and are a useful communication tool for both business and personal use, for example, FRS and GMRS overlap in the United States, resulting in substantial pirate use of the GMRS frequencies. Use of the GMRS frequencies (USA) requires a license; however, most users either disregard this requirement or are unaware. Canada reallocated frequencies for license-free use due to heavy interference from US GMRS users. The European PMR446 channels fall in the middle of a United States UHF amateur allocation, and the US FRS channels interfere with public safety communications in the United Kingdom.

15. The spread-spectrum scheme used in eXRS radios allows up to 10 billion virtual “channels” and ensures private communications between two or more units.
