Developed specifically for M2M installations, the WilsonPro Pro Signal 4G direct-connect amplifier system is based on the same time-tested, market-proven technologies powering our entire line of commercial cellular signal boosters. The Pro Signal 4G is ready to integrate with cellular modems, providing reliable signal that ensures successful data transfer. This booster kit works with all U.S. cellular networks. The Pro Signal 4G's compact form factor makes it an ideal component for installations in weak signal environments. The Pro Signal 4G kit includes the Wilson 4 in mini magnet cellular antenna for maximum system gain to overcome weak signals. The Pro Signal 4G is FCC certified. The Pro Signal 4G allows OEMs to source a compact, powerful and highly compatible signal booster that is ready to deploy. Integrators can more easily custom design M2M communication systems that fit in tightly constrained spaces. In locations where cellular signals are weak due to distance from the cell site, terrain features, or building materials like concrete and steel, the Pro Signal 4G provides a strong, reliable signal.brbr Direct connect amplifier connects directly to data modem. Improves transmissions speeds while reducing resending of data. Configurable to fit virtually any M2M (machine to machine) install. Boosts 4G, 3G, and 2G for all carriers. Bidirectional amplified signals to and from the cell tower. Auto-power control ensures maximum output. Now with passive RF bypass failover. If the Pro Signal 4G loses power, the amplifier is "bypassed" so that the external antenna maintains connection to the modem.
