The LAP-GPS model is a PtMP AP device that makes use of the latest 802.11ac wireless protocols to achieve excellent throughput, as well as Precise GPS frame synchronisation which enables your co-located LAP-GPS devices to transmit and receive data without interfering with one another, allowing for better frequency reuse and increased network stability. The antenna design allows the LAP-GPS to serve clients within a 90 degree arc with a gain of 17dBi.
