摘要： A communication system comprises a first unit; and a second unit communicatively coupled to the first unit. The first unit is operable to receive a first original radio frequency signal via a first interface and the second unit is operable to receive a second original radio frequency signal via a second interface. The second unit is operable to output a first reproduced radio frequency signal via the second interface, the first reproduced radio frequency signal being derived from the first original radio frequency signal. The first unit is operable to output a second reproduced radio frequency signal via one of the first interface and a third interface, the second reproduced radio frequency signal being derived from the second original radio frequency signal. The first interface is operable as a simplex interface when the second reproduced radio frequency signal is output via the third interface and as a duplex interface when the second reproduced radio frequency signal is output via the first interface.

摘要： 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. 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.

摘要： A hub unit is configured to digitize first and second analog radio frequency signals in order to generate first and second digital data, respectively, indicative of the first and second analog radio frequency signals. The first and second analog radio frequency signals are broadcast from first and second base stations, respectively, associated with first and second cellular service providers, respectively, using first and second air interfaces, respectively. The first and second digital data are transported to a radio access node using a shared transport medium. The radio access node is configured to reconstruct versions of the first and second analog radio frequency signals from the first and second digital data, respectively, using first and second digital-to-analog converters and is also configured to generate first data packets from a first data radio frequency signal. The first data packets are communicated to the hub unit using the shared transport medium.

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.

摘要： A method of determining a boundary of a subframe in a time division duplexing (TDD) system is provided. The method detects a power level of a signal on at least one radio frequency, the signal comprising at least one subframe. A time-domain correlation is done on the detected signal with a first reference signal, wherein the first reference signal represents at least one subframe. The location in time of a boundary of the at least one subframe of the detected signal is determined based on the correlation of the detected signal and the first reference signal.
