B14 (700 MHz)

The B14 (700 MHz) band is a part of the radio spectrum that is specifically used in the United States, often referred to as the "Upper D Band". This band operates in the 700 MHz frequency range, which is known for its excellent propagation characteristics, allowing signals to travel further and penetrate buildings more effectively than higher frequency bands. This band is particularly significant as it is used by FirstNet, a nationwide wireless broadband network dedicated to public safety. The objective of this network is to provide a reliable, secure and resilient communication system for first responders and public safety personnel in the United States.
