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 toensure 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!Yes – finally!

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
