17 How Japanese market moves towards LTE? DoCoMo selected LTE (2.1GHz, Band1, currently used for 3G) NEC plans to deliver commercial product without DoCoMo specific application at e/2008. SBM planning to introduce LTE on 1.5GHz (Band11, currently used for PDC). KDDI under investigation between LTE or UMB (Ultra Mobile Broadband) Page 17

18 Conclusion End-user needs already exists/beginning to see the onset. Operators needs exists Industry activities such as LSTI, NGMN are already in place to assure inter-operability and alignment of technology/standards/market requirements/spectrum Many operators are planning to deploy LTE starting 2010 Page 18
