The document discusses mobile data networks today and tomorrow. It outlines how mobile broadband usage has grown incredibly and customers want internet access wherever they are. Current networks use HSPA and HSPA+ technologies but face capacity constraints as usage of rich media grows. Long Term Evolution (LTE) will become the next mainstream broadband technology, offering higher speeds, more capacity, lower latency and costs compared to 3G. LTE will provide improved user experience but will evolve alongside existing 3G technologies for many years to serve customers.
