Mobile Operators Expectations

Data rate and latency
Architecture Mobility Cost of ownership Spectrum

Higher data rate and reduced latency for multimedia rich applications (competitiveness of overall customer proposition with rival technologies)

Architecture simplicity and reduced protocol complexity Seamless handover ensuring service continuity with legacy systems Reduced migration, capital and operational costs (CAPEX/OPEX), Investment protection by reusing existing assets Greater efficiency and flexibility

Need for Network Evolution
Faster, Simpler, More Efficient, Cheaper

Highly efficient radio technology
 Increased spectrum efficiency for larger carriers and therefore increase capacity  Lower cost per bit and lower prices for the end user

Simplified protocol stack & all IP network
 Reduced latency  Easier network management  CAPEX and OPEX savings

Flexibility and scalability in deployment
 Operating in various frequencies and bandwidths  Operators can start with smaller deployment and increase bandwidth as demand increase  Supports resource aggregation of radio band resources
