Point-to-Multipoint (PMP)

Cambium Networks Point-to-Multipoint

Freedom is connecting people. Options for everyone from small business to enterprises.

Cambium Networks’ ePMP product line has set the standard for high performance, scalability and reliability in harsh interference environments all at a compelling price.

With a worldwide deployment record a decade strong, our Point-to-Multipoint (PMP) and ePMP™ fixed wireless Internet solutions connect millions of people across the world. With frequency reuse enabled by GPS Synchronization and supported by PMP software, your wireless broadband network can avoid the spectrum crunch and grow with your client base.

Point-to-Multipoint distribution and access solutions enable network operators to provide high-speed wireless internet service to business and residential customers. Applications supported include data and file transfer, voice, streaming video, and video surveillance. These PMP wireless broadband networks scale from small deployments to connect remote areas to community-wide deployments with thousands of subscribers.

ePMP Overview

The ePMP™ 3000 access point and subscriber portfolio delivers high performance with interference tolerance at an affordable price. Built on the combined feature set of the ePMP 1000 and 2000, ePMP 3000 adds industry-leading throughput. Featuring a 4X4 access point and sector antenna, ePMP 3000 combines self-interference mitigating GPS synchronization with interference mitigation and combines it with Multi-User MIMO technology. Supporting an auxiliary SFP port, 80 MHz channel bandwidth and 256QAM modulation ePMP 3000 can provide up to 5x the performance as compared to the first generation of products. Proven to perform in harsh field conditions, ePMP 3000 also comes with a 3 year warranty.

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-to-back 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.
