  2. Unprecedented Mobile Voice Quality On Current 3G Networks & Beyond + FluenceTM 4GVTM-WB (EVRC-WB) Wideband Vocoder Superior voice quality compared to today’s narrow band vocoders Advanced Noise CancellationQualcomm’s advanced noise cancellation technology Leverages technologies commercially available todayNo 4G/LTE Needed

  3. 4GVTM-WB Offers Higher Quality Voice without Capacity Impact Higher Quality at same capacity as today’s EVRC Quality 4GVTM-B (EVRC-B) 4GVTM-WB (EVRC-WB) EVRC Capacity • Enhances both VoIP and Circuit Switched (CS) voice quality • Supported in select Qualcomm MSM chipsets Higher voice quality with no impact on capacity

  4. FluenceTM – Qualcomm’s Advanced Noise Cancelling Technology Speaker Secondary Microphone Primary Microphone • Superior noise reduction without impacting speech quality • Accurately identifies noise by employing secondary microphone • Commercially available in select phones Incremental software only upgrade

  5. HD VoIP is the Natural Choice when Migrating to All-IP WB VoIP WB VoIP Terminal WB 3G Network • IMS for VoIP Fixed Migration to IP VoIP NB Fixed Phone IP PSTN • End-to-end VoIP enables HD voice Higher voice quality with no impact on capacity WB – Wideband NB – Narrowband

  6. 4GVTM-WB <-> G.722 Transcoder HD Voice Demo Configuration At CES-2010 CES Booth Qualcomm CES Conference Room Internet Fixed IP HD VoIP Phone (with WB codec G.722) HD VoIP Phone (VoIP+4GVTM-WB+ FluenceTM) OTA Network QRC San Diego Asterisk/ MGW EV-DO Rev. A/B Internet PDSN

  7. HD Voice Unprecedented mobile voice quality Leverages technologies available today - 4GVTM-Wideband vocoder and FluenceTM noise cancellation Ability to differentiate voice service to high-value customers
