3GPP Band 7, frequently identified as the IMT-E (Extended) band, was a prominent 3G UMTS frequency band, utilised across Europe, Asia, and other regions. It operates under the Frequency Division Duplex (FDD) scheme, facilitating two-way communication with cell towers transmitting to mobile devices on frequencies 2620 to 2690 MHz, and receiving from mobile devices on frequencies 2500 to 2570 MHz.
Band 7 (2600 MHz) gained traction following global regulatory decisions to allocate this spectrum for advanced wireless services. Positioned at the higher end of the cellular frequency range, Band 7 offers substantial bandwidth, enabling high data throughput, which is particularly advantageous in densely populated urban areas. Its coverage radius typically ranges between 2 to 5 kilometres, influenced by urban density and infrastructural elements.
B7's higher frequency is adept at supporting large volumes of data traffic through frequency reuse and cell densification, making it ideal for cities and highly populated areas where demand for data services is intense. However, its higher frequency results in relatively limited coverage and reduced building penetration compared to lower frequency bands.
