- GSM (global system for mobile communication)The 3GPP serves as an independent intermediary between the groups of vendors who mustworktogether to create useful 3GP-enabled technologies for consumers, such as network providers, wireless service providers, and cell phone and mobile device manufacturers.
- The bandwidth and location information available to 3G devices gives rise to applications not previously available to mobile phone users. Some of the applications are:Mobile TV – a provider redirects a TV channel directly to the subscriber's phone where it can be watched.Video on demand – a provider sends a movie to the subscriber's phone.Video conferencing – subscribers can see as well as talk to each other.Tele-medicine – a medical provider monitors or provides advice to the potentially isolated subscriber.Location-based services – a provider sends localized weather or traffic conditions to the phone, or the phone allows the subscriber to find nearby businesses or friends.
