Using the RAU 10 dB Attenuation Setting

Each RAU band can, independently of the other RAUs in a system, have its uplink or
downlink gain attenuated by 0 or 10dB steps for each RAU band (1, 2, or 3). This is
accomplished by selecting the appropriate UPLINK and/or DOWNLINK attenuation
for each RAU band in the

Edit Unit Properties

screen of AdminBrowser for the

selected RAU.

•

Downlink Attenuation:

The downlink attenuator provides a mechanism to reduce

the signal strength from an RAU band. For instance, this could be for an RAU
band located near a window in a tall building that is causing excessive leakage to
the macro-network. In such a case it is important to attenuate the downlink only.
The uplink should not be attenuated. If the uplink is attenuated, the uplink sensitiv-
ity is reduced and mobile phones in the area of that RAU band will have to trans-
mit at a higher power. This would increase interference to the outdoor network
from such mobiles.

•

Uplink Attenuation:

The uplink attenuator attenuates environmental noise picked

up by an RAU band located in an area where heavy electrical machinery is operat-
ing. In such environments the electrical noise can be quite high and it is useful to
reduce the amount of such noise that gets propagated through the distributed
antenna system. Attenuating the uplink of an RAU band located in areas of high
electrical noise helps preserve the sensitivity of the rest of the system.

The effect of activating the uplink or downlink attenuators is to reduce the coverage
area of the adjusted RAU band. The coverage radius will be reduced by roughly a fac-
tor of 2. More specifically, if

d

is the coverage distance without attenuation and

d’

is

the coverage radius with the attenuation, then

where PLS is path loss slope (dBm).
