The present invention provides a fixed data communication service, a home data service (HDS), using fixed code (or some fixed code), direct sequence spread spectrum, connectionless data protocol as an overlay on a cellular or PCS wireless service, And a mobile data communication service and a personal data service (PDS).

The novel overlay of the present invention is designed to provide cost-effective broadband fixed and mobile data services by overlaying a Spread ALOHA Multiple Access (SAMA) network on an existing cellular or PCS system. It provides two-way data communication to customer premises using AMR and other services, and leverages existing cellular / PCS facilities. At home, making an interface to an application can be wired (including power line signals), wireless, or a mixture of both.

In residential data services, broadband connectionless data protocols (greater than 100 kbps peak aggregation data rate in hubs) can be used for packetized digital data (eg, www input, e-mail, utility meter readings from various types of home sources). "Upstream", security system data, in-home medical data, response and / or control data for cable or direct-to-receive TVs, and building installation transmitters to local cellular or PCS communications hub stations "Is used to transmit data signals. From the hub station, the cellular / PCS provider routes the packet data entering the packet network for delivery to the various types of receiving parties addressed in the packet itself.

HDS providers are not only building hardware and software required to collect data and send data to cellular / PCS hubs, but also add on hubs needed to receive and decode data from hundreds or thousands of buildings within cell boundaries. Supply hardware and software. The system enables unidirectional and bidirectional communication.

Data acceptance capabilities are provided as an aid to the communication capabilities and overlays of existing cellular / PCS systems, which do not cause disruptive interference with existing voice and / or other connection-oriented services.

There are two approaches to wireless design. HDS is implemented by sharing the spectrum assigned to a cellular or PCS system, or by using completely separate allowed or unlicensed frequencies. In the former case, most of the wireless system of a cellular or PCS hub station is shared with HDS (ie, antennas, transmitters, receivers, amplifiers, etc.). In the latter case, most of these systems are provided separately as part of the HDS.

In a personal data service, the data service is delivered to the individual directly via mobile and / or portable devices that are mobile (as in the case of a normal cellular or PCS subscriber) or mobile from place to place. All other components described above for the HDS implementation apply all except for the characteristic application.

In this configuration, the PDS is integrated into portable voice handsets used in today's cellular and PCS or implemented in proprietary devices such as wireless modems, two-way pagers and other kinds of wireless mobile data devices. This implementation functions to provide mobile users with two-way paging, e-mail, Internet access (including www), medical condition monitoring, and other services. In addition, PDS is utilized for efficient data communication for package or asset tracking, vehicle tracking, and other commercial or industrial mobile data services.

The present invention, in addition to the existing connection-oriented cellular or PCS system, or in addition to the communication structure such as dedicated cellular, overlay spreading ALOHA data communication capable of wideband connectionless data transmission without replacing their existing connection-oriented services Focusing on. Power, alarms, and home health monitoring are some of the many data sources in the home. The present invention focuses on digital telecommunication systems between home and existing cell hubs and modified cell hubs. The present invention in PDS format provides an overlay data service to a mobile user.

The spreading ALOHA system described in US Pat. No. 5,537,397 is preferably used to separate data packets arriving substantially simultaneously at the hub from HDS and PDS data services.
