Safety and regulatory information
This section describes important safety and regulatory guidelines that must be observed by personnel installing or
operating PMP 450 equipment.
Important safety information
To prevent loss of life or physical injury, observe the safety guidelines in this section.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
PMP 450 units must be properly grounded to protect against lightning. It is the user’s responsibility to install the
equipment in accordance with national re gu lations. In the USA, follow Section 810 of the Na tional 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 of the outdoor unit be contracted to a
professional installer.
Powering down before servicing
Always power down and unplug the equipment before servicing.
Primary disconnect device
The AP or SM unit’s 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.
iv
pmp-0047 (March 2014)
RF exposure near the antenna
Radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the
power to the PMP 450 uni t before undertaking maintenance activities in front of the a ntenna.
Minimum separation distances
Install the AP/SM 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 3-14.
Important regulatory information
The PMP 450 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.
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 PMP 450. 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.
USA and Canada specific information
The USA Federal Communications Commission (FCC) has asked manufacturers to implement special features to
prevent interference to radar systems that operate in the 5250-5350 and 5470-5725 MHz bands. These features must
be implemented in all products able to operate outdoors in the UNII band. The use of the 5600 – 5650 MHz band is
prohibited, even with detect-and-avoid functionality implemented.
Manufacturers must ensure that such radio products cannot be configured to operate outside of FCC rules;
specifically it must not be possible to disable or modify the radar protection functions that have b e e n d emonstrated
to the FCC.
In order to comply with these FCC requirements, Cambium supplies variants of the PMP 450 for operation in the
USA or Canada. These variants are only allowed to operate with Country Codes that comply with FCC/IC rule.

Security advice
Cambium Networks systems and equipment provide security parameters that can be configured by the operator
based on their particular operating environment. Cambium recommends setting and using these parameters
following industry recognized security practices. Security aspects to be considered are protecting the
confidentiality, integrity, and availability of information and assets. Assets include the ability to communicate,
information about the nature of the communications, and information about the parties involved.
In certain instances Cambium makes specific recommendations regarding security practices, however the
implementation of these recommendations and final responsibility for the security of t he system lies with the
operator of the system.

PMP 450 Planning Guide
Overview of PMP 450
This section introduces the key features, typical uses, product variants and components of the PMP 450.
Purpose
Cambium PMP 450 Series networks are designed for wireless point-to-multipoint links i n the unlicensed 2.4 GHz,
3.5GHz, 5.4 GHz and 5.8 GHz bands. Users must ensure that the PMP 450 Series complies with local operating
regulations.
The PMP 450 Series adds dramatically increased network throughput and capacity. The PMP 450 Series enables
network operators to grow their business by offering more capacity for data, voice and video applications.
Key features
The Cambium PMP 450 Series offers the following benefits:
• Cambium’s highest performing point-to-multipoint solution, with up to 90 Mbps usable throughput
• State-of-the-art MIMO (Multi-In Multi-Out) technology
• Better spectral efficiency than other MIMO alternatives
• Efficient GPS synchronized, scheduled TDD operation for easy Access Point site deployment and performance
that is consistent regardless of subscriber lo a ding
• A range of cost-effective subscriber device solutions to meet the business case of any network application
• MIMO Matrix B: This technique provides for the ability to double the throughput of a radio transmission under
proper RF conditions. Different data streams are transmitted simultaneously on two different anten nas.
nLOS benefits and limitations
In addition to providing LOS (Line-Of-Sight) connectivity, use of OFDM technology can provide nLOS (near LineOf-Sight) connectivity and somet imes NLOS (Non-Line-Of-Sight) conne ctivity:
• LOS: the installer can see the AP from the SM and the first Fresnel zone is clear.
• nLOS: the installer can see the AP from the SM, but a portion of the first Fresnel zone is blocked.
• NLOS: the installer cannot see the AP from the SM and a portion or even much of the first Fresnel zone is
blocked, but subsequent Fresnel zones are open.

PMP 450 Planning Guide
Figure 1 Line Of Sight Diagram
Whereas multi-pathing degrades a link in some technologies (FSK, for example), OFDM can often use multipathing to an advantage to overcome nLOS, especially in cases where the Fresnel zone is only partially blocked by
buildings, “urban canyons”, or foliage. OFDM tends to help especially when obstacles are near the middle of the
link, and less so when the obstacles are very near the SM or AP.
However, attenuation through walls and trees is substantial for any use of the 2.4/3.5/5.4/5.8 GHz frequency bands.
Even with OFDM, these products should not be expected to penetrate walls or extensive trees and foliage.
Typical deployment
The PMP 450 Series consists of Access Point Modules and Subscriber Modules. The radio link operates on a single
frequency channel in each direction using Time Division Du plex (TDD).
Applications for the PMP 450 Series include:
• High throughput enterprise applications
• nLOS video surveillance in metro areas
• Urban area network extension
• Network extension into areas with foliage
Greenfield deployment
The PMP 450 Series equipment may be deployed as a standalone network deployment offering a high-speed access
network.

Access Point (AP)
The AP is a self-contained unit that houses both radio and networking electronics. The AP is supplied in a
connectorized configuration for use with an exte rnal antenna. Connectorized units with external antennas c an cope
with more difficult radio conditions.

Network connection
The network connection to a PMP 450 Series AP is made via a 10 BaseT or 100 BaseT Ethernet connection. Power
is provided to the AP over the Ethernet connection using a patented non-standard powering technique.
AP power supply
The AP power supply generates the AP supply voltage (29 VDC) from the external DC source and injects the
supply voltage into the AP.
The power supply is connected to the AP and network equipment using Cat5e cable with RJ45 connectors. See
Cabling and lightning protection on page 1-36.
The PMP 450 AP can use the GigE power injector.
