Abstract

To provide a high-speed link between a wireless localloop (WLL) fixed access unit (FAU) that provides high-speed packet data access and a personal computer (PC) where the PC may be a significant distance away from the FAU (typically 300' to 500') without the requirement to install cabling additional to that already installed in a home, i.e., typically telephone cabling.

HIGH SPEED USER PREMESES CONNECTIVITY FOR WIRELESS LOCAL LOOP PACKET DATA - 99E9502US

1. Please give a brief, descriptive title to your invention: "High speed user premises connectivity for WLL packet data"

2. Briefly describe the problem (or problems) which your invention solves:

To provide a high-speed link between a wireless localloop (WLL) fixed access unit (FAU) that provides high-speed packet data access and a personal computer (PC) where the PC may be a significant distance away from the FAU (typically 300' to 500') without the requirement to install cabling additional to that already installed in a home, i.e., typically telephone cabling.

To enable simple installation of this link by WLL operator .

To enable multiple PC's (ifrequired) to connect simultaneously to one WLL FAU.

To enable the PC to be relocated within the user premises without operator intervention or reinstallation.

To use user premises telephone wiring for high-speed data connection and yet still provide plain old telephone service (POTS) concurrently, and without interruption.

3. Describe the prior approaches you know of wwhich add or attempt to solve the same problem(s) most nearly similar to the problem your invention solves:

A solution for transporting data and voice concurrently over unshielded twisted pair - the type of cable using in house wiring is Asymmetric Digital Subscriber Line (ADSL) and its' derivatives Synchronous DSL and Consumer DSL. These are primarily ainmed at providing high-speed data with concurrent voice traffic links between user premises and a telephone company's Central Office (CO). AlS/CDSL uses frequency division multiplexing (FDM) to enable voice and data to be carried on the same unshielded twisted pair (UTP). Wireline operators will most likely use this technology to provide high-speed packet data access. However, due to the bandwidth of ADSL and SDSL, filters need to be placed in the home to split the signal into POTS- ard AlSDSL. A/SDSL therefore is not appropriate for a shared POTS and data link within the home. CDSL on the other hand sacrifices bandwidth to remove the need for filters. CSDL is proprietary (Rockwell) and extremely new. It is still aimed at home to CO connectivity.

A refinement of ADSL is the "Home Ethernet LAN"- systens on the market or shortly to be on the market . that provides local area network (LAN) functionality over UTP through the use of ADSL-Iike technology.

It too does not require filtering and can provide connectivity between many devices simultaneously. Any phone jack in the home may be used as a LAN access point. It is the novel use of this technology for providing a link between the PC and F AU that this invention addresses.

None of these technologies are currently employed for high speed packet interconnect within a WLL service.
