Thanks to Wi-Fi Smartphones, Mobile VoIP is Growing Steadily

  1. With all the mobile web data traffic being generated these days by new smartphones and the resultant load on backhaul as well as the need to build out network, you would think the carriers would love to provide a revenue generating UMA/GAN gateway service (such as T-Mobile@Home) to reduce their wireless carrier infrastructure overhead (new towers, additional backhaul fibre, financing, etc.) not to mention zoning and other regulatory issues associated with cell tower placement. With WiFi it’s actually the user paying the, say, $100 overhead to buy the hardware to create a WiFi access point.

  2. A growing number of network engineers are starting to make plans for all IP mobile networks. This will require the gradual re-assignment of the channelized voice allocations (which are now more or less arbitrary form the cell site to the MSO).

    W will probably see the wholesale conversion within 5 years, but that is not to say that it will be flat rate, either. All IP over mobile is just a way to look at channel overhead.

  3. Om, you are right that truphone is competitive with AT&T during landline calls to India (truphone 10 cents, AT&T 32 cents). Truphone, however, is NOT competitive with AT&T to calls to Europe, Japan and other 1st world countries.

  4. OM, I have used VoIP on my WinMo smartphone for years (skype) but it has been haphazard use and mostly limited to international calls, once every 6 months – maybe I need to get out more often :-). The problem with mass adoption of VoIP, is there is no clear and compelling value prop to the average mobile user, my grandmother for instance.

    She just wants to pick up her wireless phone, tap the digits and make a call and doesn’t want to be bothered with the skype client, skype out balances, EVDOrA/wifi connection, etc…

    In the carrier model (my job), the economic benefits are unclear, especially when a voice network is existing and generating revenue. Balance that with minute plans, free mobile to mobile, the case becomes even murkier. International calls seem to be the only use. Wait and see….

  5. Om – calls over WiFi work great if you are near a reliable hotspot – at home or in the office. To make truly _mobile_ international calls from anywhere you have to use some other services – there is a number of iPhone apps that do that.

    My current favorite is Voxofon.com web app for iPhone.

    The international calls go through local access numbers, so you have full operator’s coverage (you do use your plan minutes though). The intl part of the call has really VoIP prices (from 1.3 c/min). Although it is a web app UI works smoothly and does not feel like a web page. Absolutely worth checking out.
