3GPP Band 8, also known as the E-GSM (Extended GSM) band, was a fundamental 3G UMTS frequency band, renowned for its widespread use globally, following B1 (2100 MHz) in terms of deployment popularity. Operating as a Frequency Division Duplex (FDD) band, it allows for bidirectional communication, with cell towers transmitting to mobile devices on frequencies 925 to 960 MHz, and receiving from mobile devices on frequencies 880 to 915 MHz.
The global prominence of Band 8 (900 MHz) is largely due to its early adoption for GSM services and subsequent transition to 3G, facilitated by regulatory decisions worldwide. As a lower frequency band, it offers extensive coverage and excellent building penetration, making it particularly effective in rural and suburban areas. The coverage radius can easily span beyond 30 kilometres in regional areas, while in urban areas, the range is influenced by the urban landscape.
Band 8's lower frequency is highly advantageous for broad area coverage and deep indoor signal penetration. This makes it an ideal choice for network operators seeking to provide robust and reliable coverage, especially in regions with challenging topographies or dispersed populations.
