The wireless technology roadmap now extends to IMT-Advanced with LTEAdvanced
being one of the first technologies defined to meet IMT-Advanced
requirements. LTE-Advanced will be capable of peak throughput rates that
exceed 1 gigabit per second (Gbps).
• Future networks will be networks of networks, consisting of multiple-access
technologies, multiple bands, widely-varying coverage areas, all selforganized
and self-optimized.
• GSM-HSPA has an overwhelming global position in terms of subscribers,
deployment, and services. Its success will continue to marginalize other
wide-area wireless technologies.
• In current deployments, HSPA users regularly experience throughput rates
well in excess of 1 megabit per second (Mbps) under favorable conditions,
on both downlinks and uplinks, with 4 Mbps downlink speed commonly
being measured. Planned enhancements such as dual-carrier operation will
double peak user-achievable throughput rates.
