PMP/PTP 450 Series
Cambium PMP/PTP 450 Series networks are designed for wireless point-to-multipoint and point-to-
point links in the unlicensed/licensed 900 MHz, 2.4 GHz, 3.5 GHz, 3.65 GHz, 5.4 GHz and 5.8 GHz
bands. Users must ensure that the PMP/PTP 450 Series complies with local operating regulations.
The PMP/PTP 450 Series enables network operators to grow their business by offering more
capacity for data, voice and video applications.
Key features
The Cambium PMP/PTP 450 Series offers the following benefits:

Cambium’s point-to-multipoint and point-to-point solution, with up to 230 Mbps usable
throughput

State-of-the-art MIMO (Multi In Multi Out) technology

Efficient GPS synchronized, scheduled TDD operation for easy Access Point site deployment
and performance that is consistent regardless of subscriber loading

A range of cost-effective subscriber device solutions to meet the business case of a 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 using the same modulation levels as the MIMO-B
mode, namely: QPSK, 16-QAM, 64-QAM and 256-QAM but it provides an additional combining
gain.
