ClearFill Star CDMA

connectors), 1900 MHz band signal and splits it into two simplexed signals to connect to two
BSIs.
Each BSI has simplexed (forward, reverse separate) RF connectivity (two connectors per
band class). Each BSI is a single carrier device (by configuration) but is capable to accept a
multiple RF carrier signal: The BSI discerns (by configuration) the specific RF carrier which it
shall convert to Ethernet. If two in-band (e.g. 1900) carriers are present (typically 1x EV-DO,
1x voice indoors), two BSIs (one twin BSI with 2 independent BSIs) are needed.
For CDMA, there is only one type of (RF dualband) BSI which can handle either, 850 or PCS
signals. The BSI has two pairs of (simplex) connectors per band class (850 and 1900). The
system configuration (via CFS NMS) will set each BSI, making it operate either in 850 or
1900, and either 3G-1X or EVDO.
RF levels at interface BTS and ClearFill®Star:
Downlink (BTS to POI):
POI Input Power 0 dBm +/- 6 dB
BSI Input Power is – 57 dBm
POI attenuator setting so that BSI level is kept
Uplink (POI to BTS):
BSI output noise – 38.5 dBm at max gain , -51.5 dBm at min gain.
BSI output power (carrier @ full loading and max. gain): -4 dBm
POI attenuator setting nominal 49, up to 63 dB in 1 dB steps.
BTS Input noise level is -87.5 to -101.5 dBm (at max. gain)
3.7.4.2 Caution - system delay
As every type of distributed system, ClearFill®Star introduces considerable system delays
(latency) which need to be considered for proper setting of BTS parameters (e.g. search
window).
Delay times are dependent from the specific system topology. Approximate values for system
delay times are:
Downlink (BSI to RRH):
67.0 micro seconds (e.g. simple topology, 2 GES layers)
71.5 microseconds (e.g. typical topology, 3 GES layers)
75.0 microseconds (e.g. complex topology, 4 GES layers)
Uplink (RRH to BSI):
130 microseconds (e.g. simple topology, 2 GES layers)
131 microseconds (e.g. typical topology, 3 GES layers)
132 microseconds (e.g. complex topology, 4 GES layers)
