An In-building cellular enhancement system, commonly implemented in conjunction with a distributed antenna system (DAS), is a telecommunications solution which is used to extend and distribute the cellular signal of a given mobile network operator (hereafter abbreviated as an MNO) within a building. In these environments, the in-building cellular enhancement system will connect to the carrier’s signal source which is typically a bi-directional amplifier or a base transceiver station. This signal source transmits (and receives) the mobile network operator’s licensed radio frequency. This frequency is then transported within the building using coaxial cable, optical fiber or Category 5e/Category 6 twisted pair cable. In-building coverage antennas are strategically placed to provide the best overall coverage for users.
