The WilsonPro Enterprise 4300/4300R is a commercial-grade, in-building cellular amplifier that represents the latest in cell signal boosting technology-including a revolutionary industry-first, three outdoor-antenna-port configurations. Depending on cell tower locations, using up to three outdoor antennas (each dedicated to a specific frequency band to collectively amplify signals from multiple towers) helps maximize coverage in commercial spaces up to 100,000 sq.ft. Based on user need or preference, the Enterprise 4300/4300R can also utilize "common mode" as a default; using only a single outdoor (donor) antenna and a single port to receive cell signals. With wired or LTE access (using the built-in cellular modem) to the WilsonPro Cloud for remote functionality, the Enterprise 4300/4300R provides integrators and building managers with the capability to remotely manage, monitor, and adjust their amplifier, as well as receive real-time updates on a smartphone or tablet. Immediate notification of issues, such as system failure, oscillation, or change in signal strength is also provided via text or email. The Enterprise 4300/4300R generates up to 26 dBm in uplink power- enabling it to reach towers at much greater distances. With up to 17 dBm in downlink power, it's also one of the most powerful amplifiers in its price range. With all four indoor-antenna ports equipped with up to 17 dBm downlink power of their own, each of the Enterprise 4300/4300R's four indoor antennas can effectively broadcast signal. The "R" model name signifies its rack-mount option. This amplifier includes a 3-year manufacturer's warranty and a 30-day money-back guarantee.
