Developing a mobile VoIP
application that rivals PSTN and
mobile phone quality.
Mapping Phone Space
                       Just like Google spiders
                        web space, we spider
                        phone space
                       Currently maintaining a
                        live map of phone menus
                        for over 500 companies
                        in North America.
                       No cooperation from
                        those companies
                        required

 Working to
 ensure a
 quality VoIP system

•choosing the correct speech codec,
•the impact of latency,
•jitter buffer design
             Better than PSTN
• VoIP allows for better than PSTN/mobile
  experience
  – HD voice can lead to greater intelligibility, comfort
    and improved end-user experience

                                     Yes – finally!
               So Many Codec Options
                            iSAC
         RTAudio
                                    G.729.1

                  EVRC-WB
         Impact of IP Networks
• While HD voice important, need to account for
  network impairments as important
  – Wireless networks particularly challenging
  – Need for rapidly adapting jitter buffer and smooth
    packet loss concealment
 Mobile platforms inherently challenging

• Low complexity solution to maximize
  limited processing power and battery
• Noise suppression to handle
  excessive background noise
• Hands Free operation requires
  acoustic echo cancellation
• Small display and camera placement
  issues for video
            The Game Changers




  The iphone OS and Android OS have changed the communications
landscape, their inherent challenges and what it means for application
   developers building solutions for mobile unified communications
        The biggest game changer
• Why ? It proved:
   – UI matters
   – OEMs can demand operator revenue pie
   – Customers care about the phone, not
     just service
       • In Q408, ATT added 2.1m new subscribers, out of
         which 36% were NEW iphone subscribers (not
         old AT&T users upgrading)
       • Iphone users give AT&T $94.5 ARPU compared to
         avg of $60
   – Power to 3rd party developers
OS SDKs compared
    “Web” programming mobile tools
•   Concept:
     – Building apps for mobile phones is complex. Different languages, UI, etc.
•   Solution:
     – Build using HTML, CSS, Javascript.
•   Key Players:
     – PhoneGap, RhoMobile, Mojo SDK (Palm’s Web OS)
•   How:
     –   App developer writes code in HTML/CSS/JS/Ruby etc.
     –   Headless browser is instantiated
     –   Browser renders UI
     –   Browser executes JS
     –   JS hooks & URI hooks for plugins
•   Advantages
     – Consistent, predictable, scalable UI (limited by browser capabilities)
     – Fast development
•   Disadvantages
     – Generally slower, does not work with all browsers/phone platforms, still nascent technology
       wrt stability
     – Not good for realtime graphics/heavy apps
