6.2 Parameters that Do Not Apply to the MC-Series System
The following parameters have no effect on the RFN system. There is no functional equivalent in
the MC-Series System and as such can be ignored.
6.2.1 combinerType
This parameter specifies the type of combiner used to connect the cells Base Radios to the
antenna. The options are hybrid and cavity. The MC-Series System is similar to a cavity type
combiner physically but it does not have the same frequency limitations as the cavity combiner
that this parameter is used for.
6.2.2 maxTx
No Information available. RFN does not use this value.
6.3 Recommended Datafill Parameters
The following parameters need to be set differently than what is currently set with Motorola BR.
These settings are not required, but recommended for best operation.
6.3.1 bcchInterleave = 4
This parameter defines how far apart the BCCH slots are spaced in the PCCH. RFN recommends
this value so as to maximize the number of outbound CCCH messages that are possible with the
system.
6.3.2 pcchInterleave = 6
This parameter defines how far apart the PCCH slots are spaced. This must be set to 6 if the
bcchInterleave is set to 4.
6.3.3 PCC = -65 (may change)
The power control constant is broadcast on the BCCH and is used by the MS to calculate a target
value for its transmit power. For Indoor, Pico and Micro-Cell applications this value will vary
depending upon the RF environment (i.e., if used outdoors the value will be quite different from
an indoor scenario). The default value should be calculated in accordance with Motorola
guidance detailed in the Datafill Parameter Guide. It should be noted that in cases in which the
Mobile subscribers are near the antenna source (downlink limited), the handsets could transmit at
a much lower level than is the case with a Macro site. Lowering this parameter forces the mobile
to operate at fairly low TX level thus conserving battery life. In cases where the MC-Series is
connected to a fiber DAS the gains and losses of the paths should be taken into consideration.
Additionally the level of uplink interference should be considered when determining this value.
