LAS VEGAS—Wireless operators are moving toward a flat, all-IP network architecture so they can deliver the flood of mobile data offerings more cost-efficient. As a first step, Nokia Siemens Networks is currently providing its standardized pre-LTE solution Internet-HSPA (I-HSPA).  According to the company, I-HSPA allows new license winners to implement a flat all-IP network compatible with all legacy HSPA devices. It also preps their networks for the LTE evolution with a simple software upgrade.

Originally launched at the Mobile World Congress, NSN’s LTE solution for radio and core networks includes the Flexi Multimode Base Station, Mobility Management Entity (MME) and System Architecture Evolution (SAE) gateway. The base station lets operators deploy W-CDMA/HSPA and LTE in all major frequency bands, including the 700 MHz and 1.7/2.1 GHz bands.

Sue Spradley, NSN’s North American Region head, said new license winners are looking for fast time-to-market with their networks, and NSN’s LTE solution caters to that need.
