Wireless internet access system
First Claim
1. A system for interfacing wireless user apparatus with a data network interconnecting a plurality of host sites identified by respective network addresses, said system comprisingreceiver means for receiving a request originated by said wireless user apparatus and forwarding the received request to said system via an upstream link for delivery to one of said host sites identified in said request, said request including a request for particular information supplied by said one of said host sites,a fist controller for receiving said request from said upstream link, and for (a) reformatting said request into a form recognized by said data network and including in said reformatted request a return address identifying a particular, independent downstream link formed from a transmission media independent of the upstream link, (b) supplying the resulting reformatted request to said network for delivery to said one host site, and (c) supplying to a second controller interfacing with said independent downstream link information associating the latter link with a particular address that indirectly identifies a particular transmission coverage area in which the wireless user is located,said second controller, operative upon receipt of a response from said one host site, associates the received response with said particular address and reformats said response in accordance with a predefined protocol, andtransmission means selected as a function of said particular address for transmitting the reformatted response directly to the wireless user apparatus via the downstream link.

Abstract
A facility is provided for establishing a relatively low-speed path from a user desiring to access the well-known Internet and establishing a high-speed path from the Internet to the user so that the data speed accommodates both the user'"'"'s requests and a response from an Internet web/host site. Moreover, a user may be mobile, in which case the low-speed path is a conventional wireless path. In most cases, a predetermined spectrum of frequencies, such as one or more television channels, is used as the high-speed path from Internet.
