Publication number: 20120121249Abstract: Systems and methods for optical path protection for distributed antenna systems are provided. In one embodiment, a system comprises a hub and at least one node located remotely from the hub. The hub is coupled to the node by first and second fiber paths, the first fiber path comprising an uplink fiber and a downlink fiber, the second fiber path comprising an uplink fiber and a downlink fiber. The node is coupled to the downlink fibers of the first and second fiber paths via an optical combiner, and is further coupled to the uplink fibers of the first and second fiber paths via an optical splitter. The node further monitors a signal quality of a downlink optical signal and communicates to the hub information indicative of the signal quality. The hub switches communications between the hub and the node from the first to second fiber path based on the information.Type: ApplicationFiled: January 19, 2012Publication date: May 17, 2012Applicant: ADC TELECOMMUNICATIONS, INC.Inventors: John Sabat, JR., Thomas G.

Publication number: 20110258693Abstract: 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.Type: ApplicationFiled: June 27, 2011Publication date: October 20, 2011Applicant: LGC WIRELESS, INC.Inventors: John Sabat, JR., Jeffrey R.

Patent number: 7313626Abstract: 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.Type: GrantFiled: March 29, 2001Date of Patent: December 25, 2007Assignee: ADC Wireless Solutions LLCInventors: John Sabat, Jr., Jeffrey R.

Patent number: 6587479Abstract: A simple and low cost architecture for coupling wireless local area 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 format and up-converted to a carrier frequency suitable for the CATV plant. Alternatively, the transport signals may be converted to IEEE 802.3 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).Type: GrantFiled: June 14, 1999Date of Patent: July 1, 2003Assignee: OpenCell Corp.Inventors: Charles H. Bianchi, Ken C. Greenwood, John Sabat, Jr.
