Keeping in touch through VoIP
Anna, a recent college graduate working as a consultant, is a good example of what mobile VoIP services have to offer.
Her operator has given her the opportunity of using a WLAN-enabled multiradio device and a VoIP service subscription to stay in touch with her friends and family at home and on the road. Replacing her PC-based Internet VoIP service, she is now able to enjoy the benefits of Internet calls via her mobile phone by connecting to her home WLAN network or public hotspots. Seamless handovers from WLAN to cellular networks mean that she is able to use the same mobile device wherever she is.
She also now has access to a number of rich services that let her communicate with her friends via video and text, as well as voice. When she was on vacation in Paris recently, for example, she was able to show a friend the photos she had taken using her mobile phone while she was talking to her over the Internet, and later send a 'wish you were here' video message to her parents.
Since all her communications are now channelled through a single device, Anna's friends and family can always reach her, either by voice, text, instant message, video call, or any other method. Anna can also use presence features (such as 'busy' or 'travelling') to indicate her availability to her contacts, as well as manage incoming communications depending on what she is doing. Some of these activities utilise cellular networks, while others are more suited to WLAN access.
Whereas some of the PC-based services Anna previously used were difficult to set up, and she had separate providers for her telecom services, she now gets all the functionality she needs in one and the same package from a single operator – through one highly intuitive, easy-to-use interface.
