System Overview
The RDL-2000 is a high-performance, high-speed wireless Ethernet bridge for use in a
commercial, industrial, business, or government environment. The system includes a 5.4
- 5.8 GHz radio using a time division duplexing (TDD) RF transceiver to transmit and
receive on the same channel.

The all-outdoor radio is housed in a weatherproof aluminum alloy case and can be used
with external flat panel or parabolic antennas. When equipped with a narrow beam
antenna the RDL-2000 supports long-range operations in clear line of sight (LOS)
conditions. An indoor PoE power adapter provides operational power for the RDL-2000
and connectivity to the local Ethernet network using a standard outdoor approved
Ethernet cable.
For each PTP link, one RDL-2000 is configured as Master Unit (MU) and controls the
wireless link. This function is transparent to all Ethernet operations. The Master uses a
scheduled request/grant mechanism to arbitrate bandwidth requests from the remote
Slave Unit (SU) to provide non contention based traffic with predictable transmission
characteristics. A unique identifier (MU ID) can be specified to ensure wireless links are
established only between designated pairs of RDL-2000 units. Encryption can be
enabled for secure data transmission over the air.
