Cambium Networks ePMP Beam-forming Product line has set the standard for high performance, scalability and reliability in harsh interference environments all at a compelling price. The ePMP 2000/3000 is the next generation Access Point that brings Interference Tolerance to a whole new level with Cambium’s unique Hypure Technology which combines Intelligent Filtering and Smart Beam-forming. The ePMP 2000 Access Point System consists of a high performance, GPS Synchronised Access Point Radio with Intelligent Filtering, a new compact high performance Access Point Antenna and an optional Smart Beam-forming Antenna.

The Intelligent Filtering of the Access Point works for both receive and transmit. It protects any channel from noise from off-channel interferers with a filter that dynamically moves around the channel. On the transmit side, it protects the RF environment by reducing off-channel transmission noise.
- The Smart Beam-forming capability works to mitigate the effects of on-channel interference. The System learns the locations of each served Subscriber Module and forms a narrow beam towards the desired Subscriber Module while that radio is transmitting in the uplink. This reduces the gain on the uplink for on-channel interferers that are transmitting at an azimuth angle different than the Subscriber Module. Detailed information on beam forming is on the Cambium web site.
Features:
-
Beam-forming algorithms maximise the Received Signal Strength Indication (RSSI) and Error Vector Magnitude (EVM) of the radio uplink
-
By mitigating the effects of uplink interference, packet retransmissions are kept to a minimum which allows for high throughputs and avoids the extra latency of retransmissions
-
An increase in throughput and reduction in retransmissions on the uplink can also increase downlink throughputs for TCP traffic which relies on efficient transmission of acknowledgements for optimal performance
