To meet the increased capacity demanded by higher data throughput in the country, Etisalat UAE has been forced to add new antennas at existing sites on rooftops or towers for UMTS 900 MHz or LTE 1800 MHz bands. Most of the time, they are facing situations where rooftops are already full of antennas—or towers are already overloaded, with serious stability and wind-load issues.
One solution is a same-band combiner—a unit that combines two base stations on the same band (GSM900 and UMTS900) into a common port to reduce the number of antennas required. But introducing a passive unit in the RF path usually leads to an insertion loss that reduces the power available for coverage and capacity.
To minimize this power loss, CommScope has 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 low loss combiners are custom solutions tailored to the client’s spectrum, which enable carriers to reduce the number of antennas and speed up network expansion. After successful trials performed at outdoor and indoor sites, Etisalat UAE decided to adopt the low loss combiner UMTS900 solution to upgrade their network sites.
