DOWNLINK DATA %, RANGE, AND CONTROL SLOTS
The Downlink Data parameter on the AP's and BHM's Configuration => General page can be set
in 1% increments between 10% and 90%. The default as shown in
In order for U.S. model 5.4 GHz PTP Series radios to meet FCC DFS compliance, the Downlink
Data has been limited to 10-65% at the Backhaul Master. For all other regions of 5.4 GHz PTP
230 Series radios and all regions of 5.8 GHz PTP radios, the Downlink Data range remains 10-
90%.
The Range parameter on the AP's Configuration => General page can be set in 1-mile
increments between 1 and 30 miles for PMP 430 5 and 10MHz channel bandwidth and between
1 and 24 miles for PMP 430 20MHz channel bandwidth. The default as shown in
miles. Set the Range to the distance of the furthest SM from any AP in the area. The Range
parameter effectively determines frame structure of the Canopy over-the-air protocol, especially
turn-around guard time. Setting Range the same across a geographical area give best overall
performance.
Range does not change transmit power levels. Do not set a higher Range than needed. A higher
Range gives no higher power and slightly reduces throughput to allow for higher air delay and
turn-around time.
If the Range is set to greater than 5 miles, the SM limits the Downlink Data to a maximum of
85% to avoid close-in SMs having registration issues. For example, a Range of 6 miles and a
Downlink Data of 90% is not allowed. Operationally,
if the Downlink Data % is set to greater than 85% and the user enters a range greater
than 5 miles, the module will reset the Downlink Data % to 85%
if the range is set to greater than 5 miles and the user enters a Downlink Data % of
greater than 85%, the module will reset the Downlink Data % to 85%.
