B2 (1900 MHz)

3GPP Band 2, commonly referred to as the PCS band, is a significant 3G UMTS3G UMTS: UMTS is an umbrella term for the third generation radio technologies developed by the 3GPP. UMTS specifies a complete network system, for which the radio access component, known as UTRAN, uses WCDMA technology to offer greater spectral efficiency and bandwidth to mobile network… frequency band, particularly in the Americas. Operating as a Frequency Division Duplex (FDDFDD: A communication technology that uses separate frequency bands for transmitting and receiving operations. This technique enables simultaneous bi-directional communication by allocating one frequency band for upstream (transmission from the user equipment to the base station) and another distinct…) band, it facilitates communication between the cellular network and mobile devices over distinct frequencies: it transmits from the cell tower to the mobile device on frequencies 1930 to 1990 MHz and receives from the mobile device on frequencies 1850 to 1910 MHz.

The widespread adoption of Band 2 (1900 MHz) in North and South America can be traced back to regulatory decisions that allocated the 1900 MHz spectrum for PCS (Personal Communications Service) in the 1990s. This band falls in the middle range of cellular frequencies, offering a balanced compromise between coverage and capacity. The coverage area of Band 2 is generally extensive, with a typical cell radius of about 5 to 15 kilometers, influenced by geographical and urban density factors.
