The present invention is generally directed to a system for monitoring a variety of environmental and/or other conditions within a defined remotely located region. In one aspect, a system is configured to monitor utility meters (613) in a defined area. The system is implemented by using a plurality of wireless transmitters (614), each integrated into a sensor (612) adapted to monitor a particular data input. The system also includes a plurality of transceivers (221) that are dispersed throughout the region at defined locations. The system uses a local gateway (210) to translate and transfer information from the transmitters to a dedicated computer (260) on a network (230). The dedicated computer collects, compiles and stores the data for retrieval upon client demand across the network. The computer further includes means for evaluating the received information and identifying an appropriate control signal to be applied at a designated actuator.

System and method for monitoring and controlling remote devices

An intelligent gateway device provided at a premise (home or business) for providing and managing application services associated with use and support of a plurality of digital endpoint devices associated with the premises. The device includes a communications and processing infrastructure integrated with a peer and presence messaging based communications protocol for enabling communications between the device and an external support network and between the device and connected digital endpoint devices. A services framework at the gateway device implements the communications and processing infrastructure for enabling service management, service configuration, and authentication of user of services at the intelligent gateway. The framework provides a storage and execution environment for supporting and executing received service logic modules relating to use, management, and support of the digital endpoint devices. Thus, the gateway device provides a network-based services point of presence for a plurality of digital endpoint devices at the premises.

A registration protocol may be used by the monitoring module and the remote site in generating the messages communicated during the registration process. The monitoring module may gather and generate various identification information to be included in the registration protocol messages. The registration information provided by the monitoring module may be stored at the remote site in a database server having a database. A confirmation message may be communicated from the remote site to the monitoring module that may either acknowledge successful registration or report that an error occurred during the registration process.

Systems and methods for the automatic registration of devices

Wireless communication networks for monitoring and controlling a plurality of remote devices are provided. Briefly, one embodiment of a wireless communication network may comprise a plurality of wireless transceivers having unique identifiers. Each of the plurality of wireless transceivers may be configured to receive a sensor data signal from one of the plurality of remote devices and transmit an orginal data message using a predefined wireless communication protocol. The original data message may comprise the corresponding unique identifier and sensor data signal. Each of the plurality of wireless transceivers may be configured to receive the original data message transmitted by one of the other wireless transceivers and transmit a repeated data message using the predefined communication protocol. The repeated data message may include the sensor data signal and the corresponding unique identifier. Furthermore, at least one of the plurality of wireless transceivers may be further configured to provide the original data messages and the repeated data messages to a site controller connected to a wide area network. The site controller may be configured to manage communications between the wireless communication network and a host computer connected to the wide area network.

Wireless communication networks for providing remote monitoring of devices

The high quality PCS communications are enabled in environments where adjacent PCS service bands operate with out-of-band harmonics that would otherwise interfere with the system's operation. The highly bandwidth-efficient communications method combines a form of time division duplex (TDD), frequency division duplex (FDD), time division multiple access (TDMA), orthogonal frequency division multiplexing (OFDM), spatial diversity, and polarization diversity in various unique combinations. The method provides excellent fade resistance. The method enables changing a user's available bandwidth on demand by assigning additional TDMA slots during the user's session.

Method for frequency division duplex communications

A wide area communications network communicating data from a plurality of network service modules through a plurality of remote cell nodes and intermediate data terminals to a central data terminal. The wide area communications network collects network data generated by a plurality of physical devices such as gas, water or electricity meters, located within a geographical area. The wide area communications network is a layered network having a hierarchical communications topology. The central data terminal controls network operation. Intelligence exists at all layers of the network, thereby easing the workload of the central data terminal. The intelligence attributed to each module is a function of the application of that module.

Wide area communications network for remote data generating stations

A method for communicating data between a central data terminal, a plurality of intermediate data terminals, a plurality of remote cell nodes, and a plurality of network service modules, using a plurality of frames with each frame having a plurality of channels. The plurality of intermediate data terminals transmit IDT-synchronization signals to the plurality of remote cell nodes on a first channel of the frame. The plurality of remote cell nodes transmit RCN-synchronization signals to the plurality of network service modules on a second channel of the frame. The network service modules transmit data from a plurality of physical devices, using radio waves, as NSM-packet signals to the plurality of remote cell nodes using a fourth channel of the frame. The plurality of remote cell nodes store the incoming NSM-packet signals and, responsive to a first polling signal transmitted in a third channel of the frame from a particular intermediate data terminal, transmit the NSM-packet signals to the intermediate data terminal as RCN-packet signals on a fifth channel of the frame. The intermediate data terminal in turn stores the RCN-packet signals received from the plurality of remote cell nodes and, responsive to a second polling signal transmitted from the central data terminal on a sixth channel of the frame, transmits the RCN-packet signals as an IDT-packet signal on a seventh channel of the frame to the central data terminal.

Communications protocol for remote data generating stations

A radio communications network for transmitting data from a plurality of remote stations to a central station is provided. This system is particularly proposed for automatic meter reading systems in which the remote stations are located at utility meters. The system includes an array of receiving stations arranged relative to the remote stations so that the messages from each remote station can be received by at least two and preferably four of the receiving stations providing a high level of duplication of messages. The remote stations transmit utility usage information obtained from a previous time period at a random time subsequent to the time period so that message collisions can occur. High level of duplication provided by the increased number of receiving stations reduces the message loss. A quiet period during which the remote stations are prevented from transmitting can be used for communication between the receiving stations and the central station.
