3GPP Band 14, often known as the "700 PS" (Public Safety) band, is a notable 3G UMTS frequency band primarily allocated in North America for public safety communications. Operating under the Frequency Division Duplex (FDD) regime, it supports two-way communication, with cell towers transmitting to mobile devices on frequencies 758 to 768 MHz, and receiving from mobile devices on frequencies 788 to 798 MHz.
The designation of Band 14 (700 MHz) for public safety use was a strategic decision taken to provide dedicated, reliable communication channels for emergency services and first responders. The 700 MHz frequency was chosen due to its excellent propagation characteristics, which include extensive coverage areas and superior building penetration. This makes it highly effective for use in a wide range of environments, from densely urban to rural areas.
