Mobile VoIP Challenges

iphone_main_overview20080609.jpgToday, Global IP Solutions (GIPS) announced the public availability of a whitepaper that highlights the challenges and opportunities critical for high quality when implementing mobile VoIP, called "Implementing VoIP for iPhones and Smartphones."

The paper can be found at http://gipscorp.com/products/gips_in_action.php, and addresses how developers can overcome problems inherent in mobile IP communications, such as packet loss and delay, jitter, acoustic echo and OS tuning.

Forget these challenges. You want to know the #1 challenge facing mobile VoIP? It's the wireless carriers or the operating system companies themselves (Apple, Microsoft) forcing cellphone manufacturers to offer "crippled" VoIP. What do I mean by crippled VoIP? I mean mobile phones such as the iPhone which can do VoIP but only over a WiFi data connection and not over 3G. As I wrote before, Apple will in fact BLOCK VoIP applications from running over the cellular data network. What in the bloody hell kind of half-ass crippling of VoIP is that? Apparently, Steve Jobs aims to protect their cell network buddy AT&T from having VoIP calls be "minute stealers" from the regular cell network.

Windows Mobile isn't much better. It does allow VoIP over 2.5G/3G, but often cripples access to the internal handset earpiece. You have to send the audio out the external speakerphone, which is not nearly as good quality. Often the external speaker is on the back of the phone and doesn't have nearly enough volume, so you're forced to flip the handset on your ear back-and-forth when speaking or listening.

In any event, it might br worthwhile to check out GIPS' whitepaper. Here's some more details:
