Zain Bahrain has contracted Sweden’s Ericsson for a 4G network transformation, including deployment of LTE technology across the existing network, plus pre-paid charging solutions, consulting and systems integration services. Ericsson will replace existing 2G and 3G radio network equipment while adding 4G functionality with the Ericsson RBS 6000 family of base stations. The vendor will also deploy Evolved Packet Core technology with triple-access SGSN-MME and Evolved Packet Gateway based on Ericsson SSR 8000 family of Smart Services Routers as well as MINI-LINK PT and SP for IP backhaul. As a part of the agreement, Zain will also implement Ericsson’s Charging System for pre-paid subscribers as ‘phase one’ of the convergent charging and billing in one solution (CBIO). Zain Bahrain launched commercial LTE services in April this year, and last month was awarded additional frequencies for 4G expansion.
