4Motion 725 System Manual
To avoid BS-BS interference, the ul-dl-allocation must be identical in all BSs in a
geographical region.
The range is 4-7 or 10 for bandwidth of 5 or 10MHz, 3-5 or 7 for bandwidth of
7MHz.

4.7.2.6.8 Neighbor with Beamforming
The beam forming mechanism that may be used by neighboring BSs is based on
symmetry in performance between uplink and down link. To compensate for
possible differences due to HW of the ODU, a special low-level calibration signal is
transmitted periodically in each link. During the time this calibration signal is
transmitted all other radio links of the same BS and all its neighbors should not
transmit, to reduce potential interference. The Beam Forming mechanism ensures
that all neighboring BSs operating in Beam Forming mode will enter into silent
mode when necessary. A Micro BTS operating in Matrix A or B mode should enter
into silent mode when necessary (based on frame number information) only if it
has neighboring BSs operating in Beam Forming mode.
The options are Yes and No. Set to Yes only if the unit has at least one neighbor
BS operating in Beam Forming mode.
The default is No.
