5.2.3 Signal Levels and Channel Configuration
This section provides a description of the RF Gain setting criteria (set via the Controls and Params
Pane), the criteria determining the number of available bands and a step-by-step procedure of the
signal level and channel configuration procedure.
5.2.4 RF Gain Setting Criteria
The RF Gain is set automatically by the Repeater’s SALC function. The function sets the optimum
gain without exceeding the isolation limit.
The gain range is up to 73dB for all bands and is set by default to its maximum value.
The gain will then be modified automatically to its optimum value by the SALC mechanism. This
mechanism performs gradual learning of traffic load characteristics and adjusts the Repeater RF Gain
accordingly. (See section
1.3 for more information on the SALC mechanism).
5.2.5 Bandwidth and the Number of Available Bands
Each repeater supports either one or two bands (single-band or dual-band). Up to Six sub-bands may
be defined per two bands per repeater (e.g. on a dual-band repeater supporting bands 850MHz and
1900MHz, 4 sub-bands may be set for the 850MHz band and 2 sub-bands for the 1900MHz band,
with a total sum of 6 sub-bands). The number of available sub-bands or channels depends on the
technology and selected bandwidth as detailed below (note that some bandwidths (e.g. 15 or 20MHz
at 700/1900 MHz GSM) take up two channel resources).
The information can be viewed via the Band Info tab (described on the following page).
