The PMP 450i AP 16 dBi, 90° sector antenna does not support frequency reuse between collocated
APs because of poor F/B ratio.
To achieve frequency re-use between collocated APs, please use the PMP 450i AP Connectorized
and external antennas.
For details on frequency planning, please see Radio Frequency planning on page 3-15.
PMP/PTP 450 Series
Cambium PMP/PTP 450 Series networks are designed for wireless point-to-multipoint and point-topoint links in
the unlicensed/licensed 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 adds dramatically increased network throughput and capacity. 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 highest performing point-to-multipoint solution, with up to 150 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 loading
•
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 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.
