Europe uses the 2.4GHz band and the5.0GHz band. The 5.0GHz frequency range used in Europe is known as the European Conference of Postal and Telecommunications (Conferenceof8 Chapter 1 Introduction to Wireless Network ConceptsEuropean Post and Telecommunication) CEPT A, CEPTB, CEPT C, and CEPT C bands. The United States uses the 900MHz, 2.4GHz ISM and 5.0GHz Unlicensed National InformationInfrastructure (UNII) bands. Japan uses 2.4GHz and 5.0GHz as its own bands. The U.S. bands are described in more detail below.2. 900 MHzThe 900 MHz band runs from 902 MHz to 928 MHz. it is likely that you are very familiar with this band because you probably have a cordless phone that operates in this range. This is a good way to understand the wireless channel. Perhaps you have picked up your cordless phone but only hear some silence or even the sound of a neighbor talking on his cordless phone. If this happens, you can press the channel button and switch to a channel without too much interference. When you find an interference-free channel, you're ready to make a call. The channel you are switching to is just a different frequency range. This way, even if your phone and your neighbor's phone both operate in the 900MHz range, you can select a channel in that range and have multiple devices working at the same time.
