Overview of ePMP
This section introduces the key features, typical uses, product variants and components of the
ePMP.
PURPOSE
Cambium ePMP Series products are designed for Ethernet bridging over point-to-multipoint
microwave links in the unlicensed 5 GHz and 2.4 GHz bands. Users must ensure that the ePMP
Series complies with local operating regulations.
The ePMP Series acts as a transparent bridge between two segments of the operator and
customers’ networks. In this sense, it can be treated as a virtual wired connection between the
Access Point and the Subscriber Module. The ePMP Series forwards 802.3 Ethernet packets
destined for the other part of the network and filters packets it does not need to forward.
KEY FEATURES
The ePMP system is a high performance wireless bridge for Ethernet traffic with a maximum UDP
throughput of 200+ Mbps (40 MHz Channel Bandwidth). It is capable of operating in line-of-sight
(LOS) and near-LOS conditions. Its maximum LOS range is 13 mi (20 MHz channel bandwidth) or 9
mi (40 MHz channel bandwidth).
Utilizing GPS sync, the ePMP is an ideal fit for networks that require capacity and reliability for
superior QoS in remote and underserved areas. The integrated PTP and PMP solution features an
efficient GPS synchronized operational mode that permits highly scalable frequency reuse.
ePMP operates in the unlicensed 5 GHz and 2.4 GHz bands and supports a channel bandwidth of
up to 40 MHz. It is available with an integrated antenna or in connectorized version for use with an
external antenna.
The wireless link is primarily TDD based. System Release 1.2.3 added a Flexible Frame Ratio
option which provides improved latency and throughput under unsynchronized operational mode.
From a network point-of-view, the ePMP wireless link is a transparent Layer 2 bridge. It offers
limited switching capability in order to support a primary and a secondary (future release) Ethernet
port on the Subscriber Module.
ePMP supports quality of service (QoS) classification capability and supports three traffic priorities.
Management of the unit is conducted via the same interface as the bridged traffic (in-band
Management).
System Release 1.3.4 adds support for RADIUS EAP-TTLS authentication and VSA support for MIR.
When deployed with a sector antenna, the ePMP 1000 GPS Sync Radio can be configured as a GPS
synchronized Access Point serving ePMP Integrated Radios configured as Subscriber Modules.
When deployed with a high gain point to point antenna, the ePMP GPS Sync Radio can be
configured to be a GPS Synchronized Backhaul Master, forming a PTP link with another ePMP
Radio module.
Powered by Hypure™ technology, ePMP 2000 features Smart Beamforming. This powerful
addition to your network creates narrow, targeted beams to each subscriber, rather than relying on
a traditional wide beam, blocking out multiple sources of interference to keep performance high.
ePMP 2000 also includes Intelligent Filtering, working automatically to clean up the signals
received by the access point as well as keep its owns transmissions clean. This helps not just that
single access point reach optimum performance, but the whole tower too.
