9. 9 Strategic Direction Strategically, TR45.5 will continue to: –Collaboration with other Standards Organizations Develop Interworking Specifications in support of other technologies (LTE, WiMAX) Collaborate with other standards groups, e.g., 3GPP and WiMAX Forum on interworking Collaborate with 3GPP to develop Signaling Conformance Specifications for Interworking –Partner with 3GPP2 and its Organizational Partners and Marketing Representation Partners –In Partnership with 3GPP2, TR-45.5 has a cooperative relationship with the Femto Forum and Broadband Forum –Work with ITU Provide ITU with updates of cdma2000 as IMT-2000 and Broadband Wireless Access (BWA) Provide ITU with input on Femtocell develop,

10. 10 Strategic Direction Strategically, TR45.5 will continue to: –Develop new technologies and services –Concentrate on environmentally friendly systems and services: Consider the Green Initiatives –Continue to improve battery life –Support of DTX in the Codec, would reduce the amount of energy consumption –1x Revision E has the ability to put many terminals on the same carrier, thereby reducing power consumption. A base station can reduce power consumption by supporting a larger number of terminals on the same carrier.

11. 11 Challenges Increase capacity while maintaining service quality and system coverage to satisfy market demands Enhance data throughput and reduce latency to accommodate the existing and emerging data services Continue to improve battery life of the terminal Continue to meet the time to market requirements by the industry Continue to meet industry requirements for emerging markets related to Smart Card development

12. 12 Next Steps/Actions Continue to develop new technologies and services for the cdma2000 industry Innovate and improve existing systems in TR45.5 Work closely with regulatory bodies to provide solutions for: –location services, –emergency notification, –new frequency plans, –other governmental services
