PMP/PTP 450i Series
The PMP/PTP 450i Series is a high performance wireless bridge for Ethernet traffic. It is capable of
operating in line-of-sight (LOS), near-LOS and non-LOS propagation conditions. It supports 900 MHz, 3
GHz, and 4.9 to 5.925 GHz frequency band.
Key features
The PMP/PTP 450i Series has extensive quality of service (QoS) involving traffic classification, traffic
policy and shaping capability.
The Cambium PMP/PTP 450i Series offers the following benefits:
Cambium’s high performing point-to-multipoint solution, with up to 310 Mbps (40 MHz Channel
Bandwidth and 5 ms Frame Period) usable throughput for PMP and PTP
State-of-the-art MIMO (Multi In Multi Out) technology
Upto 7.5 bps/Hz spectral efficiency
Increased Packet Processing rate
Efficient GPS synchronized, scheduled TDD operation for easy AP/BHM site deployment and
performance that is consistent regardless of SM/BHS loading
A range of cost-effective subscriber device solutions to meet the business case of any network
application
MIMO B Mode: 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
antennas
MIMO-A mode: This mode of operation has same modulation levels as the MIMO-B mode, namely:
QPSK, 16-QAM, 64-QAM and 256-QAM. This mode increases system reliability in the links.
Timing synchronization via CMM4, CMM5, or UGPS
