PMP 400/430 and PTP 200/230 Series
If a connectorized AP or BHM has been purchased and the operator has provided the antenna,
the Transmitter Output Power must be configured based on that antenna and consistent with
local or regional regulations. For example, if a 5440APC is being used with a 15 dBi antenna,
then the maximum setting allowed to meet 27 dBm EIRP is the full 12 dBm of which the radio is
capable.
IMPORTANT!
It is the responsibility of the operator and professional installer to ensure
Transmitter Output Power is set within regulatory limits for their country
or region. These must be set or confirmed on initial configuration and
after a module is reset to factory defaults, and should be confirmed after
the software on a module is upgraded.
In most cases the operator will want to set the AP's Transmitter Output Power to the maximum
allowed so as to have the greatest overall range and the greatest range for 3X operation. It may
be useful to reduce Transmitter Output Power when Canopy systems are located close together,
with good coverage given because of their proximity and full power isn't needed, or in cases
where an operator is trying to reduce interference from the Canopy system to other systems.
Each SM's Transmitter Output Power is automatically set by the AP. The AP monitors the
received power from each SM, and adjusts each SM's Transmitter Output Power so that the
received power at the AP from that SM is not greater than -60 dBm. In addition, for 5.4-GHz SMs,
the AP sets the SM's Transmitter output power so the SM's EIRP will be within regulatory
requirements.
PMP 400/430 Series networks use Auto-TPC because OFDM technology is more sensitive to
large differences in power levels from SMs operating at various distances from the AP than the
single carrier technology used in Canopy FSK.
PTP 200 Series bridges do not use Auto-TPC – the operator sets Transmitter Output Power on
the "Configuration => Radio" page of both the BHM and the BHS.
PMP 400/430 and PTP 200/230 Series modules display the typical Canopy "Receive Power
Level" as shown in
