ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of Invention
The present invention generally relates to wireless communication. More specifically, the present invention relates to a system and method for providing users with a wireless medium using a mobile or travelling base station.
2. Background
The advent of multimedia computer services now allows people to enjoy customized newspapers and magazines, educational programming, and other audio/visual media in the comfort of their own home or office. Although there is a strong demand for such services, deployment has been hampered by the wide bandwidth these products require for transmission. Conventional telephone lines and cellular systems typically support narrower bandwidths, and are inadequate to handle such transmissions. The enormous amount of information comprising these multimedia products tends to bog these systems down unacceptably or to overwhelm them completely resulting in incomplete transmissions. One possible solution is to bolster cellular systems infrastructures and increase the available RF bandwidths these systems are currently allotted. Such a solution, however, is costly and adds to the existing and vehement contention over bandwidth allocation. Consequently, a need exists for a system of delivering multimedia services to user without burdening existing infrastructures. The present invention fulfills this need among others.
SUMMARY OF THE PRESENT INVENTION
The invention relates to a system and method that employs a mobile base station for periodically travelling to a particular area and transmitting and/or receiving information to and/or from a user within the area. The mobil base station has storage means for storing information and mobil wireless communication means for performing wireless communication within its broadcast area. In a complimentary configuration, the user has a terminal with storage means for storing information and terminal wireless communication means for cooperating with the mobil wireless communication means to facilitate wireless communication therebetween. The method of performing a wireless transfer of information involves moving the mobile base station to the user's particular geographical area such that the broadcast area includes the user's terminal thereby enabling the mobil wireless communication means and the terminal wireless communication means to cooperate and establish a wireless communication link. Next, a direct wireless communication link is established between the mobile base station and the terminal of the user. A transfer of information then occurs between the storage means of the mobile base station and the storage means of the terminal via the wireless communication link. In a preferred embodiment, the wireless communication link is a wireless LAN interface for facilitating transmission of wide bandwidth information.
In accordance with the invention, the user can be provided with periodic access to an otherwise unavailable wireless medium without the need for an elaborate and costly wireless infrastructure.
