Concluding The Shelf’s five part series featuring technology that could make it big it 2008 The Shelf examines mobile VOIP.
VoIP is a Voice Over Internet Protocol service that enables users to make voice calls across the internet. VoIP involves sending voice information in digital form in discrete packets rather than by using the traditional circuit-committed protocols of the public switched telephone network (PSTN). The major advantage of VoIP is that by using the internet telephony users can avoid the charges existing telephone networks already have in place.
In addition to IP, VoIP uses the real-time protocol (RTP) to help ensure that packets get delivered in a timely way.
VoIP has already taken of in a huge way with the help of increasing numbers of domestic broadband connections, and users are already seeing the savings VoIP can provide, especially with international calling. Big names like BT are now even incorporating VoIP calling into their broadband and call packages.
With savings already being made in the home through VoIP, challenging existing domestic telephone networks, it is only a matter of time until VoIP services trickle into mobile phone networks too. Thanks to the increasing number of handsets fitted with 3G this look a certain development in 2008.
All that is technically required for mobile VoIP is a 3G speed mobile data service, a technology is readily available in handsets currently on the market. The next stumbling block is preventing mobile networks from prohibiting VoIP mobile communication, after all they want to protect their revenue stream. The only additional hold up for mobile VoIP after this is the requirement for a soft client on the mobile handset that a customer wishes to use. Skype is one example, and recently teamed up with 3 to release the first VoIP handset.
The catch here is the VoIP calls still have to travel over a mobile network, (unless made through wireless hot-spots or the like) so whether this remains true VoIP is a question the pessimists among us may like to ask. Truephone is a good example here.
