Potential Applications of 4G

Some key potential applications of 4G are:

1. Virtual Presence: 4G system gives mobile users a "virtual presence"; for example, always-on connections that keep people involved in business activities regardless of whether they are on-site or off.
2. Virtual Navigation: A remote database contains the graphical representation of streets, buildings, and physical characteristics of a large metropolis. Blocks of this database are transmitted in rapid sequence to a vehicle, where a rendering program permits the occupants to visualize the environment ahead .
3. Tele-medicine: 4G will support remote health monitoring of patients; for example, the paramedic assisting the victim of traffic accident in a remote location must access medical records and may need videoconference assistance from a surgeon for an emergency intervention. The paramedic may need to relay back to the hospital the victim's x-rays taken locally.
4. Tele-Geoprocessing Applications: The combination of Geographical Information Systems (GIS). Global Positioning Systems (GPS). and high-capacity wireless mobile systems will enable a new type of application referred to as tele-geoprocessing. Queries dependent on location information of several users, in addition to temporal aspects have many applications.
5. Crisis-Management Applications: Natural disasters can affect the entire communications infrastructure is in disarray. Restoring communications quickly is essential. With wideband wireless mobile communications Internet and video services, could be set up in hours instead of days or even weeks required for restoration of wireline communications.
6. Education: Educational opportunities available on the internet for individuals interested in life-long education high speeds are unavailable to client in remote areas because of the economic unfeasibility of providing wideband wireline internet access. 4G wireless communications provides a cost-effective alternative in these situations
