To minimise this power loss, CommScope
developed a new type of in-band combiner
designed to deliver only 0.5 dB of insertion
loss – compared with traditional one-size-
fits-all hybrid combiners that lose 3 dB and
essentially waste most of the power available.
CommScope’s 900 MHz and 1800 MHz
LLC models are custom combiner solutions,
tailored to the client’s spectrum, that
enable carriers to reduce the number of
antennas and speed up network expansion
using sameband combiners to introduce
new systems like UMTS900 or LTE1800
at existing sites – or to share tower
infrastructure with other operators and
reduce tower load. CommScope LLCs have
excellent spectrum efficiency, with a minimal

guard band of 0.6 MHz for LLC 900 and 0.7
MHz for LLC 1800.
Because of their flexibility, CommScope LLCs
are ideal for site-sharing applications, where
the antenna, jumpers and feeder cables are
shared between two or three operators to
open up new capacity on existing sites.
CommScope LLCs simplify site
sharing for Ooredoo
Ooredoo Tunisia executed a successful
trial using a CommScope 900 MHz low-
loss combiner for site sharing between
Ooredoo and another carrier, swapping
out a hybrid 3 dB combiner with the LLC
900 unit.
Drive test and statistic counters analysis
indicated that site traffic was increased by
50% and received total wideband power
(RTWP) was reduced by 20% after the LLC
900 installation.
The solution also increased site revenue by
50% and improved network performance
and quality of experience, while delivering
cost reductions due to cost sharing between
two operators. The trial was so successful that
Ooredoo is planning to use the LLC solution
with a 12-port antenna for a three-operator
shared site.
“Installing the CommScope LLC 900
combiner achieved our goals of improving
network coverage and RTWP while allowing
