IBM Patent Application Implementing Satellite Radio for Receiving Data

On November 09, 2006, IBM had a patent application disclosed that proposes to use satellite radio as part of a web access system to download data to a lap top device. A wireless laptop makes a request for data that is passed through a cellular device, which relays the request to a cell tower. The request is relayed to a base station, where the data is processed. Once the data is processed, it is uplinked to a satellite radio satellite. The data is beamed to the laptop by the satellite. Below is a couple of interesting passages. IBM makes the case for the satellite radio transmission, but they never describe it in great detail:

[0004] As will be described hereinafter, the present invention makes use of satellite radio technology for receiving broadcasts to compensate for these shortcomings of celllular telephony in receiving high speed data. Satellite radio receiving technology has been developing over the past decade until the present when hand held receivers are mass marketed for broadcasts from two private communication satellite systems owned by SiriusRadio and XMRadio. These portable receivers would be readily integratable into the mobile wireless receiving computers, as will hereinafter be described with respect to the present invention.

[0005] However, at this point, some background information on satellite radio receivers is appropriate. The U.S. Federal Communications Commission (FCC) has allocated a spectrum in the "S" band (2.3 GHz) for Nationwide U.S. broadcasting of satellite based Digital Audio Radio Service (DARS). XM Satellite radio, for example, uses two satellites placed in parallel geostationary orbit, which is about 22,223 miles above Earth, and is the type of orbit most commonly used for communications satellites. There is a radio uplink to these two GEO satellites from a ground radio station which then bounce the signals down to the receivers on the ground. In urban areas where buildings can block out the satellite, the system may be supplemented by supporting ground transmitters. Each receiver contains appropriate hardware and software for decoding received coded/secure broadcasts. The portable satellite radio receivers have been reduced in size until they presently use antennae the size of cellular telephone antennae.

Wireless telecommunications system for accessing information from the world wide web by mobile wireless computers through a combination of cellular telecommunications and satellite broadcasting

Abstract

A hybrid cellular telephonic and satellite radio broadcast system for enabling a wireless mobile computer to rapidly and effectively access information from the Web. The combination of a mobile wireless receiving computer, with wireless cellular telecommunication associated with the receiving computer for transmitting a request for data from the receiving computer to the Web, an implementation for accessing the requested data from the Web, a satellite transponder, wireless communication for transmitting said accessed requested data to the satellite transponder, an implementation on the satellite transponder for broadcasting the accessed requested data and apparatus in the mobile wireless receiving computer for receiving the broadcast data.
