Brazilian network operator Tim Brasil has signed a contract with Nokia Siemens Networks (NSN) for the deployment and servicing of a WCDMA/HSPA network, offering high-speed mobile broadband data services in several Brazilian states in theSouth, North and North-east of the country.
NSN will be the sole 2G/3G Packet Core Network supplier for the country, and the main radio access network supplier to more than a dozen states. TIMs network will be upgraded with NSNs WCDMA Flexi base stations. NSN notes that this is the industrys smallest and most efficient base station, adding that it will enable TIM to minimize network deployment and operational costs. NSN says that the energy efficiency of the Flexi base station underpins its commitment to environmentally sustainable solutions.
NSN has over 120 WCDMA radio network references and has enabled close to 100 operators to launch HSDPA. NSNs high-performing HSPA networks can be activated with a simple software upgrade to its existing WCDMA networks, enabling cost-effective and fast rollout. HSPA enables true mobile broadband with two key technologies, HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access) enabling data speeds of up to 14 Mbps in the downlink and up to 5.8 Mbps in the uplink, with speeds of 43 Mbps (up) and 11 Mbps (down) in the future.
