Abstract: A Time Division Duplexed (TDD) digital distributed antenna system (DDAS) that performs simulcast distribution to multiple simulcast groups while using TDD time advanced burst to negate the data rate reducing effects of transport delays. The User Plane data is adapted for eliminating time delay ambiguities across multiple simulcast digital radios. In addition, the Control and Management Plane is aggregated across multiple remote units to allow a non-modified donor digital base station to control simulcast groups.

Abstract: An architecture for providing operations and maintenance functionality in an open access wireless signal distribution system. The open access system makes use of a common, shared, distributed radio frequency distribution network and associated network entities that enable a system operator to offer access to wireless infrastructure that maybe shared among multiple wireless service providers (WSPs). The WSPs, or tenants of the operators, may obtain access in a tenant lease-space model. The open access system provides the ability for multiple tenants in a given community to share wireless equipment such as remotely located antenna sites, regardless of their specific requirements for radio frequency (RF) air interface signal protocols and/or management messaging formats. The present invention is directed to an open access Network Management System (NMS) that provides multiple tenants with an appropriate level of access and control over the system elements that carry their signaling.

Abstract: A system including a master controller, a plurality of wireless nodes dispersed in a geographic area and a plurality of traffic signal lights dispersed in the geographic area. The traffic signal lights are communicatively coupled to the master controller via the plurality of wireless nodes. Each wireless node in the plurality of wireless nodes is associated with a distinct Internet protocol address and a wireless communication link provides Internet protocol based communication between the plurality of wireless nodes and the master controller. The plurality of wireless nodes receives control data packets for the communicatively coupled traffic signal lights from the master controller via the wireless communication link. The control data packets comprise the distinct Internet protocol address and operational instructions for at least one traffic signal light communicatively coupled to the wireless node and each traffic signal light is responsive to the operational instructions in the control data packets.

Abstract: The present disclosure is directed to an open access Network Management System (NMS) that provides multiple tenants in an open access wireless distribution system with an appropriate level of access and control over the system elements that carry their signaling. For example, in addition to forwarding messages from tenant-controlled NMSs to the open access system elements, the open access NMS preferably acts as a caching firewall to ensure that the tenant NMS are permitted privileges to access only those system elements to which they are a properly assigned. A database function included with the open access NMS may be used to build and maintain a database of operations and maintenance information from autonomously initiated poll and status functions. This then permits queries from tenant NMSs to be answered without the need to duplicate open system network traffic.

Abstract: A simple and low cost architecture for a distribution network is provided for coupling wireless local area network (“wireless LAN”) signals between geographically distributed access points and centrally located internetworking devices. The distribution network eliminates complexities involved with the deployment of such systems in the past, which have typically required the computer network-compatible wiring to be extended to each access point directly from an internetworking device such as a repeater, bridge, router, or gateway. The distribution network makes it economically efficient to deploy wireless local area networking equipment in locations where wired network infrastructure is not readily available.

Abstract: An architecture is provided for coupling wireless local area network (WLAN) signals between an internetworking device and a remotely located access point using a transport network. The access point is coupled to the transport network for communicating with the internetworking device. The access point includes a wireless local area network (WLAN) access point and an access point remote converter. The WLAN access point receives wireless local area network signals from wireless computing equipment and converts such signals to local area network compatible signals. The access point remote converter receives the local area network compatible signals from the WLAN access point and converts the signals to transport modulated format signals suitable for transmission over the transport network. The transport network also provides a power signal to power at least some components of the access point.

Abstract: A simple and low cost architecture for coupling wireless metropolitan area network and mobile broadband wireless network signals between geographically distributed access points and centrally located internetworking devices. A cable access point (CAP) is associated with each respective microcell. Each CAP includes a remote bridge to convert such signals to a convenient transport format depending upon the available cabling. For example, if the available cabling is a cable television (CATV) plant, the transport signals are first converted to a T1/T3 format and up-converted to a carrier frequency suitable for the CATV plant. Alternatively, the transport signals may be converted to cable modem signals. If the available cabling is twisted pair telephone type wiring, the remote bridge converts the transport signals to a suitable Digital Subscriber Line (XDSL) format. The transport signals are collected at a central distribution or head end access point (HAP).

Abstract: At repeaters or at each individual unit of a distributed antenna system, an auxiliary pilot signal is transmitted in addition to a common base station pilot signal to mobile units. The auxiliary pilot signal is unique to each repeater and each individual unit of the distributed antenna system within a local propagation area. A mobile unit measures the auxiliary pilot signals received from the repeater or distributed antenna units in the same manner it measures those of any base station pilot signal. The location of the mobile unit can be determined using well-known triangulation techniques based on the auxiliary pilot signal measurements.

Abstract: A technique for controlling a wireless communication network to provide for blossoming capacity to a relatively high capacity state and/or wilting capacity to a relatively lower capacity state. Connections in progress with active subscriber units are properly handled without the need to send explicit handoff commands from the base stations. The cell sites may be advantageously implemented with cable microcell integrators that comprise remotely deployed transceiving equipment that are interconnected to centrally located base transceiver station equipment via a broadband cable distribution network. In an initial relatively low capacity state, adjacent cells are operated at the same carrier frequency such that they form simulcast groups so that subscriber units traveling in adjacent cells will operate with the same radio channel. As demand increases, the power level of an auxiliary radio transceiver is gradually increased while the power level of the original transceiver in the cell is gradually decreased.

Abstract: A method and apparatus for providing wireless signal communications through multiple coverage areas that include narrow corridors along which much of the mobile traffic travels. The corridors are interconnected at junctions where vehicle traffic tends to slow down or stop. The invention in particular, involves a method whereby simulcast communication is used for signal communication among base station locations along the narrow corridors. In this simulcast mode, the system equipment uses the same radio frequency to provide wireless coverage in a sequence of related sites located along the corridor. Using simulcast channels, the need for handoff is reduced and or eliminated. At the junctions, the usual base transceiver station (BTS) arrangement may be provided whereby multiple radio channels are available and handoff processing occurs.
