Multi User MIMO

Achieving higher throughput in the downlink is often solved by achieving higher modulation or wider channels. In both cases, the environment and interference prevents achieving higher modulations or operating in wider channel bandwidths. ePMP 3000 employs Multi User MIMO technology (MUMIMO) to simultaneously transmit to two subscribers in the downlink and thus doubling the throughput in the downlink.

Intelligent Filtering

Noise is always a concern, and as more transmitters are deployed, will continue to be a critical factor in operation. While almost all radios have some type of filtering, many use static filters that block out only noise from outside of the radios total operating spectrum. While this provides a clear channel for operation, these systems with fixed filters still allow noise from neighboring channels to affect system performance. Cambium Networks solutions use dynamic filtering with a static filter to block noise from outside of the operating spectrum but also a dynamic filter to block out interference from adjacent channels. As the system changes to another channel, the system automatically blocks out noise from adjacent channels to improve signal quality.

Frequency Re-Use

Frequency is limited. There will never be any more of it. By re-using frequencies when deployed in back-toback configuration, a network operator can effectively use the same frequency twice to connect users. In large deployments, a network operator can connect thousands of users by re-using the same frequencies across the field service area. This technology maximizes the use of available frequency and can provide access to thousands of users in a small amount of spectrum.

GPS Synchronization

When networks become more dense, self interference becomes an issue. GPS synchronization coordinates the entire network, reduces self interference, and keeps network performance high as more subscribers are added.

Smart Beamforming and Beam Steering

As more emitters are deployed in the service area, it is important to mitigate noise and interference in order to provide reliable high-speed connectivity. The ePMP 3000 Access Point works in conjunction with the optional Beam Steering antenna to create narrow beams in the uplink to improve signal to noise ratio. Placed at the access point on a tower, the smart antenna will create tighter beams to connect with subscribers while nulling out radiation from unwanted emitters in the field.

Air Fairness

ePMP employs a sophisticated priority-based, air fairness, starvation avoidance algorithm for allocating RF resources to SMs. The allocations are based on airtime instead of throughput and so we avoid the situation where SMs in poor RF conditions take up an excessive amount of time and therefore available capacity.

ePMP 3000

Cambium Networks’ ePMP™ product line has set the standard for high performance, scalability and reliability in harsh interference environments all at a compelling price. The ePMP 3000 is the third-generation access point (AP) that carries on the interference tolerance mechanisms from ePMP 2000 but adds the power of Multi-User MIMO (MU-MIMO). The ePMP 3000 is a 4X4 MU-MIMO access point that can double the throughput at the sector level with the same channel bandwidth by serving two subscribers at the same time.

ePMP 3000L Fixed Wireless Access Point

Cambium Networks’ ePMP™ product line has set the standard for high performance, scalability and reliability in harsh interference environments all at a compelling price. The ePMP 3000L is the third-generation access point (AP) that carries on the interference tolerance mechanisms with an emphasis on high-performance in low-density point to multipoint sectors.
