OMD Must Make Hard Choices

Multi-mode Solutions

• Support all technologies with global bands needed: 2G, CDMA, TD-SCDMA, WCDMA, HSPA+, LTE, LTE-A

Global Solutions for LTE-A

• Support all major bands and band combinations for Carrier Aggregation

• Multi-sourcing suppliers for cost can results in conflicting band support

• Call quality impact?

• LTE Throughput impact?

• Power Consumption

impact?

Form Factor and Device

Components

Band Complexity –Harmonized globally, but Devices ?

• How to support as many technologies, bands and CA with effective cost

• How to get operator requirements and effectively commercialize with proper test

ODM may create different SKUs to address the hardware impact, and support as many bands needed


IMS Integration Complexity

3GPP deals with radio side, GSMA is high level requirements, and IETF may not cover all possible call flows in VoIP operating on cellular side
