Saudi Arabian operator Zain has introduced a tri-band carrier aggregation (3C) technology component on its LTE network, upping its maximum download speeds to 187.5Mbps, in partnership with equipment vendor Nokia. In order to deliver the superior speeds, the operator is aggregating 25MHz of spectrum in the 900MHz, 1800MHz and 2100MHz bands. Nokia provided its Flexi Multiradio 10 Base Station and frequency division duplex LTE (FDD-LTE) software, while also delivering network implementation and multi-layer optimisation services. The LTE-Advanced (LTE-A) service is available to eligible subscribers with Category 6 (CAT 6) devices in several high-traffic areas in Jeddah.
Ali Aljitawi, Head of Zain Saudi Customer Team at Nokia, said: ‘With this project, Zain becomes the first telecoms operator in Saudi Arabia to carry out the refarming of spectrum in the 900MHz band from GSM to LTE, and using three component carrier aggregation to increase speeds on Zain’s 4G network.’
