Zain Saudi Arabia has completed an HSPA+ trial with Nokia Siemens Networks, paving the way for an all-IP flat architecture network of the future along with significantly improved data throughput speeds.
The trial introduced a simple, flat architecture demonstrating how traffic can bypass the Radio Network Controller (RNC) and the Serving GPRS Support Node (SGSN), to deliver improved data transmission speeds. Because of the re-routing, there is no need to build in additional capacity, in effect reducing the OPEX and CAPEX. Moreover, with flat architecture the operator is well prepared for the eventual move to Long Term Evolution (LTE). I-HSPA solution also shortens the network latency rates to 45ms enabling quicker response times and enhances the overall user experience availability of data serviceshttp://www.nsn.com
