Key Messages; The technologies are here Mobile radio access technologies are already well capable of delivering a broadband experience A well coordinated standardization ensures mass adoption & economies of scale This is a global effort Users have taken HSPA to their hearts since HSPA delivers true broadband Today almost 40 ops offering user speeds of 7 Mbps In Geneva at the WRC (October-November 2007) we measured over 6 Mbps while driving in a car, and close to 1.4 Mbps uplink at the convention center – which is better than common fixed broadband HSPA is already here and has a steady roadmap and is future proof Suppliers like Ericsson are committed to future development Ericsson will release 28 Mbps end of 2008 going for 42 Mbps during 2009 We have already demoed 160 Mbps on LTE where commercial products will be released 2009 LTE is a natural evolution of HSPA and will coexist with HSPA for a long time – HSPA will be the broadband wide area coverage and LTE will provide capacity and speeds in densely populated regions when needed + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Additional Information about HSPA & LTE Ericsson conducted the world's first demonstration of end-to-end HSPA Evolution technology with speeds of up to 42 Mbps at CTIA Wireless 2008, held in Las Vegas from April 1 to 3 Speeds of up to 42 Mbps represent the next phase in HSPA Evolution. These speeds are achieved by combining new higher order modulation technology (64QAM), together with 2x2 Multiple Input Multiple Output (MIMO) antenna technology. The first step of the HSPA evolution will be introduced during 2008 Different terminal classes are being defined for LTE and it looks like around 150 Mbps will be one of the supported classes. (In our press releases we have communicated 160 Mbps for LTE.) And, it does not stop there. In the future, HSPA can achieve higher bit rates (80-160 Mbps downlink and 20-40 Mbps uplink with multicarrier solutions). Also LTE has an impressive speed evolution - it will easily reach >300 Mbps with 20 MHz spectrum, and with 100 MHz spectrum well over 1 Gbps can be achieved. Interoperability GSM/HSPA/LTE Since these technologies are all from the same family, handover and interoperability between GSM, HSPA and LTE will be secured, the user will thus never be out of coverage.
