Configuring The Transmit Power Of The Au-Re - Alvarion BreezeAccess II System Manual

2-4
Configuring the Transmit
Power of the AU-RE
The transmitted output power of the AU should be adjusted in the
following cases:
! If there is a need to cover a relatively small area and to minimize the
interference with the operation of neighboring cells.
! According to the FCC rules 15.247 (3), when operating the
equipment in a multi-point system, the RF output power must be
adjusted according to the gain of the antenna to limit the EIRP to a
maximum of 36 dBm.
Table 2-2 displays the required value of the Transmit Power Control
parameter for FCC approved antennas and for various IF cable types
and lengths. This is applicable for units in which the output power
depends on the attenuation of the IF cable.
In new AU-RE units (marked BreezeACCESS IC), the output power does
not depend on the IF cable. Table 2-3 displays the required value of the
Transmit Power Control parameter for FCC approved antennas for these
units.
NOTE:
For compliance with FCC requirements, the maximum allowed output power in units
operating in HDM Mode is 19 dBm. Therefore, when using an antenna with a net gain
of 17 dBi or lower, the Transmit Power Control parameter should be set to the
maximum value for an output power that does not exceed 19 dBm. These values are
identified clearly in the appropriate locations in the tables.
Setting the Transmit Power Control parameters is only possible in
Administrator Mode.
NOTE:
According to FCC Rule 15.204 (c), only antennas authorized as part of the FCC grant
may be used with this product.
