WebNov 29, 2024 · The Basics of 900MHz or 33-Centimeter Band. Caption: An antenna on the roof. First, the 900 MHz spectrum goes from 902 to 928MHz in the International Telecommunication Union Region 2. These are amateur radio bands on the UHF spectrum. Furthermore, their primary use is for local communications. Apart from amateur stations, … WebSuper high frequency (SHF) is the ITU designation for radio frequencies (RF) in the range between 3 and 30 gigahertz (GHz). This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres. These frequencies fall within the microwave band, so radio waves with these …
WebThe 2.4-GHz band is widely used by designers who want to build systems that can operate worldwide. In fact, it has become the frequency band of choice for such standards as Bluetooth, WLAN, and ZigBee.The 5.8-GHz band has also attracted some attention—in cordless phones or the 802.11a version of WLAN, for example.
