The AN-50e is a high-performance, high-speed wireless Ethernet bridge terminal
providing a scalable multi-service platform from a common equipment
infrastructure and management system.
The system operates in the 5.4 GHz to 5.8 GHz band and includes advanced
technologies to address inter-cell interference. The system also delivers enhanced
security through a proprietary, over-the-air encryption scheme.
The AN-50e can be equipped with a narrow beam antenna to provide high
directivity for long-range operations over 80 km in clear line of sight (LOS)
conditions.

The AN-50e system is a Class A digital device for use in a commercial, industrial
or business environment.
The system is equipped with dynamic frequency selection (DFS) to detect
interference from other devices using the same frequency and automatically take a
pre-selected action, such as disable transmission or relocate transmission to
alternative frequency. The system also includes an automatic transmitter power
control (ATPC) function to automatically adjust the Tx level of remote-end
systems to match a selected RSSI value.
The AN-50e system utilizes Redline’s advanced Medium Access Control (MAC)
design to provide efficient transmission of data in both PTP and PMP modes. In
PMP mode, the MAC incorporates a proprietary polling algorithm to support up to
250 individual subscriber stations from a single master end operating in a single
sector. Note that multiple masters can be installed on a single rooftop or tower to
provide multi-sector coverage.
