•
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 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 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 or uGPS
Table 1 gives a summary of the main PMP/PTP 450i characteristics.
