The Cel-Fi’s QUATRA networked smart booster applies Cel-Fi smart signal booster technology to applications within larger venues by allowing up to four (4) CUs to operate with a single NU. By synchronizing the outputs from multiple CUs, the coverage areas of each CU are stitched together to form one large cell that can cover an entire building, up to 50,000 sq-ft. per system. Cel-Fi QUATRA may use either an (a) off-air or (b) small cell donor input, depending on the specific coverage and capacity needs at the site. Once the system is mounted appropriately, standard CAT 5e (or better) cable is used to connect the NU with each CU. When powered-on, all network and system optimizations are performed automatically.brbrThis is a consumer device.brbrBefore use, you must register this device with your wireless provider and have your provider’s consent.
