Warning To prevent loss of life or physical injury, observe the safety guidelines in this
section.
Safety and regulatory information
This section describes important safety and regulatory guidelines that must be observed by
personnel installing or operating ePMP equipment.
Important safety information
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
ePMP devices and mounting structures must be properly grounded to protect against lightning. It is
follow Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 (USA). In Canada, follow
Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures for
grounding the outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and
connection requirements for grounding electrodes. Other regulations may apply in different
countries and therefore it is recommended that installation be contracted to a professional installer.
Powering down before servicing
Always power down and unplug the equipment before servicing.
Primary disconnect device
The ePMP power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that will be
exposed to the outdoor environment.
RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on.
Always turn off the power to the ePMP device before undertaking maintenance activities in front of
the antenna.
Minimum separation distances
Install the ePMP device so as to provide and maintain the minimum separation distances from all
persons.
The minimum separation distances for each frequency variant are specified in Calculated distances
and power compliance margins on page 6-73.
PAGE 1
Important Regulatory Information
The ePMP product is certified as an unlicensed device in frequency bands where it is not allowed to
cause interference to licensed services (called primary users of the bands).
Radar avoidance
In countries where radar systems are the primary band users, the regulators have mandated special
requirements to protect these systems from interference caused by unlicensed devices. Unlicensed
devices must detect and avoid co-channel operation with radar systems.
The ePMP provides detect and avoid functionality for countries and frequency bands requiring
protection for radar systems.
Installers and users must meet all local regulatory requirements for radar detection. To meet these
requirements, users must set the correct country code during commissioning of the ePMP
equipment. If this is not done, installers and users may be liable to civil and criminal penalties.
Contact the Cambium helpdesk if more guidance is required.
Specific expertise and training required for professional installers
To ensure that the ePMP is installed and configured in compliance with the requirements of Industry
Canada and the FCC, installers must have the radio engineering skills and training described in this
section. This is particularly important when installing and configuring an ePMP system for operation
in the 5 GHz band (5150 5250 MHz FCC only, 5250 5350 MHz, 5470 5725 MHz and 5725
5850 MHz).
Ethernet networking skills
The installer must have the ability to configure IP addressing on a PC and to set up and control
products using a web browser interface.
Lightning protection
To protect outdoor radio installations from the impact of lightning strikes, the installer must be
familiar with the normal procedures for site selection, bonding and grounding. Installation guidelines
for the ePMP can be found in section Site planning on page 2-3.
Training
The installer needs to have basic competence in radio and IP network installation. The specific
requirements applicable to the ePMP must be gained by reading this user guide and by performing
sample setups at base workshop before live installations.

OVERVIEW OF EPMP
Overview of ePMP
This section introduces the key features, typical uses, product variants and components of the ePMP
portfolio as a whole (802.11n and 802.11ac products).
Purpose – ePMP Portfolio
Cambium ePMP Series products are designed for Ethernet bridging over point- to-point microwave
links in the unlicensed 2.4 GHz, 2.5 GHz (Brazil only), and 5 GHz bands. Users must
ensure that the ePMP Series complies with local operating regulations.
ePMP devices support point-to-point microwave links in the unlicensed 5 GHz band.
The ePMP Series acts as a transparent bridge between two segments of
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.
ePMP 3000 Key Features
ePMP 3000 Access Point
ePMP 3000 is a rugged high-capacity outdoor point-to-point link wireless
device in the unlicensed 5 GHz frequency bands with amaximum UDP sector
throughput of 1+ Gbps (when operating with 80 MHzchannel bandwidth). It is
capable of operating in line-of-sight (LOS) and
near-LOS conditions. It is available as a connectorized unit for use with a
separate 4x4 MU-MIMO sector antenna and optional Smart Antenna (for
uplink beam steering).
ePMP 3000 supports backward and forward compatibility with ePMP 802.11n
devices to provide an immediate sector upgrade to 802.11ac Wave 2
performance, and also to support future upgrades of networks operating
ePMP 1000/2000 Access Points.
ePMP 3000 is based on highly-integrated wireless semiconductor
components designed to meet the IEEE 802.11ac standard, however the ePMP
3000 device has a proprietary air interface for the main
point-to-point link.
ePMP 3000 is powered by standard power-over-Ethernet to a 1000Base-T
port.
Management of the unit is conducted via the same interface as the bridged
traffic (in-band Management).
A summary of the main ePMP 3000 characteristics is listed under Table 1.

WIRELESS OPERATION
Wireless operation
This section describes how the ePMP wireless link is operated, including modulation modes, power
control and security.
MU-MIMO
The ePMP 3000 MU-MIMO access point features an array of antennas. When multiple subscriber
modules wish to communicate, the array is divided such that some antennas are used to communicate
with one subscriber, while other antennas are used to communicate with another subscriber
simultaneously.
This is contrast to a traditional wireless system, where two subscribers cannot communicate on the
same channel to the same access point at the same time without causing significant self-interference
and degrading the overall wireless network performance.
MIMO
Multiple-Input Multiple-Output (MIMO) technique provides protection against fading and increases the
probability of a received decoded signal to be usable.
Smart Beamforming (ePMP 2000/3000 series)
ePMP 2000/3000 Smart Beamforming drastically reduces 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, delivering performance gains never before seen.
Smart Antenna Key Advantages:
Eliminate Uplink Interference: Smart Beamforming delivers dramatic performance improvements
when dealing with strong co-channel uplink interference, maximizing network performance.
Consistent Performance in High Interference: By mitigating significant sources of interference,
packet loss and retransmissions are kept to a minimum, keeping your network applications working
at their best.
Improvement in Uplink and Downlink Performance: By eliminating packet loss and retransmissions
resulting from co-channel uplink interference, TCP retransmissions are greatly reduced. Other
applications also show significant performance benefits.

WIRELESS OPERATION
Time division duplexing
TDD cycle
ePMP links operate using Time Division Duplexing (TDD). The links employ a TDD cycle in which the
Access Point determines which Subscriber Modules may transmit and when based on the configured
downlink/uplink ratio (duty cycle). Three fixed Downlink/Uplink frame ratios are available 75/25,
50/50 and 30/70.
OFDM and channel bandwidth
ePMP 3000 transmits using Orthogonal Frequency Division Multiplexing (OFDM). This wideband signal
consists of many equally spaced sub-carriers. Although each sub carrier is modulated at a low rate using
conventional modulation schemes, the resultant data rate from all the sub-carriers is high.
The channel bandwidth of the OFDM signal is 20 MHz, 40 MHz or 80 MHz, based on operator
configuration.
Each channel is offset in center frequency from its neighboring channel by 5 MHz.
Adaptive modulation
ePMP 3000 can transport data over the wireless link using a number of different modulation modes
ranging from 256-QAM to QPSK. For a given channel bandwidth and TDD frame structure, each
modulation mode transports data at a fixed rate. Also, the receiver requires a given signal to noise ratio
in order to successfully demodulate a given modulation mode. Although the more complex modulations
such as 256-QAM will transport data at a much higher rate than the less complex modulation modes, the
receiver requires a much higher signal to noise ratio.
ePMP 3000 provides an adaptive modulation scheme where the receiver constantly monitors the
quality of the received signal and notifies the far end of the link of the optimum modulation mode with
which to transmit. In this way, optimum capacity is achieved at all times.

WIRELESS OPERATION
Note When operating in a region which requires DFS, ensure that the AP is configured
with alternate frequencies and that the SM is configured to scan for these frequencies
to avoid long outages.
Radar avoidance
In regions where protection of radars is part of the local regulations, ePMP must detect interference
from radar-like systems and avoid co-channel operation with these systems.
To meet this requirement, ePMP implements the following features:
The equipment can only transmit on available channels, of which there are none at initial power up.
The radar detection algorithm will always scan a usable channel for 60 seconds for radar
interference before making the channel an available channel.
This compulsory channel scan will mean that there is at least 60 seconds service outage every time
radar is detected and that the installation time is extended by at least 60 seconds even if there is
found to be no radar on the channel
There is a secondary requirement for bands requiring radar avoidance. Regulators have mandated that
products provide a uniform loading of the spectrum across all devices. In general, this prevents
operation with fixed frequency allocations. However:
ETSI regulations do allow frequency planning of networks (as that has the same effect of spreading
the load across the spectrum).
The FCC does allow channels to be avoided if there is actually interference on them.
Encryption
ePMP supports optional encryption for data transmitted over the wireless link. The encryption algorithm
used is the Advanced Encryption Standard (AES) with 128-bit key size. AES is a symmetric encryption
algorithm approved by U.S. Government organizations (and others) to protect sensitive information.
Country codes
Some aspects of wireless operation are controlled, enforced or restricted according to a country code.
ePMP country codes represent individual countries (for example Denmark) or regulatory regions (for
example FCC or ETSI).
Country codes affect the following aspects of wireless operation:
Maximum transmit power
Radar avoidance (future release)
Frequency range

SYSTEM MANAGEMENT
System management
This section introduces the ePMP management system, including the web interface, installation, alerts
and upgrades, configuration and management software.
Management agent
ePMP equipment is managed through an embedded management agent. Management workstations,
network management systems or PCs can be connected to this agent using
SFP port, over the air (Subscriber Module connection via Access Point) or by using the device WiFi
management interface.
The management agent supports the following interfaces:
Hypertext Transfer Protocol (HTTP)
Hypertext Transfer Protocol secure (HTTPs)
Simple Network Management Protocol (SNMP)
Network Time Protocol (NTP)
System logging (Syslog)
-based or On-premises Management System
Dynamic Host Configuration Protocol (DHCP)
Web server
The ePMP management agent contains a web server. The web server supports access via the HTTP and
HTTPs interfaces.
Web-based management offers a convenient way to manage the ePMP equipment from a locally
connected computer or from a network management workstation connected through a management
network, without requiring any special management software. The web-based interfaces are the only
interfaces supported for installation of ePMP, and for the majority of ePMP configuration management
tasks.

SITE PLANNING
Warning Electro-magnetic discharge (lightning) damage is not covered under
warranty. The recommendations in this guide, when followed correctly, give the user
the best protection from the harmful effects of EMD. However 100% protection is
neither implied nor possible.
Note International and national standards take precedence over the requirements in
this guide.
Site planning
Conduct a site survey to ensure that the proposed sites meet the requirements defined in this section.
Site installation
An ePMP site typically consists of a high supporting structure such as a mast, tower or building for the
devices.
Find a location for the device that meets the following requirements:
The equipment is high enough to achieve the best radio path.
People can be kept a safe distance away from the equipment when it is radiating. The safe
separation distances are defined in Calculated distances and power compliance margins on page 6-
73.
The equipment is lower than the top of the supporting structure (tower, mast or building) or its
lightning air terminal.
There is one Ethernet interface, a copper Cat5e connection from the device to the power supply
and network terminating equipment.
Grounding and lightning protection
Structures, equipment and people must be protected against power surges (typically caused by
lightning) by conducting the surge current to ground via a separate preferential solid path. The actual
degree of protection required depends on local conditions and applicable local regulations. To
adequately protect an ePMP installation, both ground bonding and transient voltage surge suppression
are required.
Details of lightning protection methods and requirements can be found in the international standards
IEC 61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984 or section 54 of the
Canadian Electric Code.

Lightning protection zones
Use the rolling sphere method (Figure 3) to determine where it is safe to mount equipment. An
imaginary sphere, typically 50 meters in radius, is rolled over the structure. Where the sphere rests
against the ground and a strike termination device (such as a finial or ground bar), all the space under
the sphere is considered to be in the zone of protection (Zone B). Similarly, where the sphere rests on
two finials, the space under the sphere is considered to be in the zone of protection.
PAGE 2-4
CHAPTER 2: SYSTEM HARDWARE
SITE PLANNING
Assess locations on masts, towers and buildings to determine if the location is in Zone A or Zone B:
Zone A: In this zone a direct lightning strike is possible. Do not mount equipment in this zone.
Zone B: In this zone, direct EMD (lightning) effects are still possible, but mounting in this zone
significantly reduces the possibility of a direct strike. Mount equipment in this zone.

Warning
Do not mount equipment in Zone A which can put the equipment, structures and life at risk.
