  • Page 115: Diagramming Network Layouts

    SM Automatic Transmit Power Control The PMP 450 AP automatically sets the transmitter output power in its SMs through a feature named Auto-TPC (Transmit Power Control). The conceptual reason for this feature is OFDM reception in the AP is sensitive to large differences in power levels received from its SMs, and by limiting power levels of close-in SMs the overall RF noise floor is lowered.

  • Page 116: Avoiding Other Interference

    PMP 450 Planning Guide Avoiding Other Interference Where signal strength cannot dominate noise levels, the network experiences • packet errors and retransmissions. • lower throughput (because bandwidth is consumed by retransmissions) and high latency (due to resends). Regular spectrum analysis is critical to RF planning. The integrated spectrum analyzer can be very useful as a tool for troubleshooting and RF planning, but is not intended to replicate the accuracy and programmability of a high- end spectrum analyzer, which you may sometime need for other purposes.
