A signal booster is a device that employs an intelligent enhancement system to lock onto cellular operators' signals while improving both transmitted and received signals, thereby significantly expanding the functional range of all mobile devices within the vehicle or installation location. With stronger connectivity and extended coverage, consumers can reliably make and maintain phone calls, send and receive text messages, enjoy faster and more consistent data and streaming experiences, and utilize these enhancements across all 5G and 4G LTE cellular devices in the vehicle or installation site.
