PERFORMANCE
HELPING OPERATORS GET
MORE MILEAGE
Leveraging Cambium’s worldwide wireless leadership,
the PMP 320 combines low-cost connectivity with
exceptional performance. This helps ensure not only
extended service at the network edge, but also a
competitive edge in customer satisfaction and return
on investment. PMP 320 connectorized Access Points (APs)
and integrated Subscriber Modules (SMs) provide a low
cost, simple, low maintenance infrastructure that offers
an attractive business case for getting maximum coverage
and revenue from 802.16e WiMAX networks. The PMP
320 offers high reliability based on field-proven toughness,
performance, scalability and ease-of-use.
•PERFORMANCE. The PMP 320 delivers high
throughput for optimized performance, serving up to 200
subscribers per sector with a typical aggregate bandwidth
of up to 45 Mbps (10 MHz channel) and even higher
throughput with Multiple Input/Multiple Output (MIMO)
technology. That means a typical four-sector tower
can provide a maximum capacity of up to 180 Mbps
across up to 800 subscribers. The PMP 320 also supports
65,000 packets per second. GPS synchronization,
supported by the Cluster Management Module, helps
reduce self-interference and maximize signal and
throughput reliability. OFDMA (Orthogonal Frequency
Division Multiple Access) and MIMO technologies provide
maximum throughput in multipath environments.
•RANGE. Because the PMP 320 is a licensed spectrum
solution, it is not subject to the system output power
restrictions of unlicensed products, allowing it to provide
higher throughput at longer range. The solution also uses
802.16e features such as turbocoding and higher levels
of error correction to maximize range.
•COVERAGE. The PMP 320 utilizes 802.16e OFDMA
technology that enables signals to perform in difficult
multipath RF locations, providing line of sight (LOS) and
near line of sight (nLOS) coverage in rugged, hard-to-
reach terrain. In addition, the solution supports MIMO
multiple antenna techniques, including MIMO Matrix A
and B to enhance coverage and capacity.
•SECURITY. With FIPS 197 Certified 128-bit AES
encryption, EAP-TTLS authentication and standard AAA/
RADIUS authentication for tiers of service, the PMP 320
offers powerful security proven to safeguard data, voice
and video transmissions against network intrusion and
identity theft.
DESIGNED FOR RELIABILITY
By design, the PMP 320 is optimized for fixed outdoor
applications to meet the connectivity needs of 3 GHz license
holders. It is part of the Cambium Wireless Broadband
Point-to-Multipoint portfolio, and designed to be deployed
as either a standalone system or as a complement to
WiMAX networks and network expansions by interoperating
with fixed WiMAX CPEs.
Today, there are currently more than 3 million Cambium
Wireless Point-to-Multipoint modules working successfully
and profitably in thousands of networks around the globe.
Our PMP solutions are proven in virtually every type of
environment: dense urban areas, sprawling suburban areas
and outlying communities located in rugged and difficult
terrain in more than 130 countries.

The PMP 320 uses
Multiple Input Multiple
Output (MIMO) technology
to optimize performance.
With two transmitters at
the AP location and two
receivers at the SM
location, the system is able
to use multipath technology
to improve reliable connec-
tivity (this is commonly
referred to as “MIMO
Matrix A”). If the radio
conditions are sufficiently
good, the PMP 320 will
automatically shift to
MIMO Matrix B, where
multipath is used to send
two independent data
streams across each link,
potentially doubling the
useable throughput.
