Chapter 1: Product description Overview of the 450 Platform FamilyPage 1-4PMP/PTP 450i SeriesThe PMP/PTP 450i Series is a high performance wireless bridge for Ethernet traffic. It is capable ofoperating in line-of-sight (LOS), near-LOS and non-LOS propagation conditions. It supports 900MHz and 4.9 to 5.925 GHz frequency band.Key featuresThe 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 230 Mbps (30 MHzChannel 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 andperformance that is consistent regardless of SM/BHS loading A range of cost-effective subscriber device solutions to meet the business case of any networkapplication MIMO B Mode: This technique provides for the ability to double the throughput of a radiotransmission under proper RF conditions. Different data streams are transmittedsimultaneously 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 thelinks. Timing synchronization via CMM4 or uGPSTable 3 gives a summary of the main PMP/PTP 450i Series characteristics.Table 3 Main characteristics of the PMP/PTP 450i SeriesCharacteristic ValueTopology PMP/PTPWireless link condition LOS, near LOS or non-LOSRange PTP Up to 186 mi (or 299 km) depending on configuration forall bandsPMP: Up to 40 mi (or 64 km) for 5 GHz bandPMP: Up to 120 mi (or 193 km) for 900 MHz bandDuplexing TDD (symmetric and asymmetric)Connectivity 1000Base-T Ethernet Main port with PoE inputOperating frequencies 902 to 928 MHz
