19 19 Interoperability 1.Importance 2.RADVISION’S Approach

20 3G-324M over TD-SCDMA for Handsets20 1. Importance Reduces the risk of recalls Mobile handsets recall is a costly process for both the operator and the handset vendor Focus on both interoperability with handsets on the market as well as future extensions (introduction of new services and codec's) Video is not as easy as Voice More codec's Capability negotiation is not a simple process Implementing the exact codec profiles properly Focus on quality in a 64Kbps bandwidth

21 3G-324M over TD-SCDMA for Handsets21 3. RADVISION’S Approach Commitment to the standardization process along with a high level of interoperability Active member in all related international organizations IMTC 3G-324M activity group co-chairman Host of the next F2F event RADVISION’S initiatives WNSRP testing with operators and handset vendors Remote IOT service on select features
