Abstract: A communication system includes master host unit, hybrid expansion unit, analog remote antenna unit, and digital remote antenna unit. Master host unit communicates analog signals with at least a first service provider interface using first bands of analog spectrum. Master host unit and hybrid expansion unit communicate first N-bit words of digitized spectrum over first digital link. Hybrid expansion unit converts between first N-bit words and second bands of analog spectrum. Hybrid expansion unit and analog remote antenna unit communicate second bands over analog medium. Analog remote antenna unit transmits and receives first plurality of wireless signals over air interfaces. Master host unit and digital remote antenna unit communicate second N-bit words of digitized spectrum over second digital link. Digital remote antenna unit converts between second N-bit words and third bands of analog spectrum. Digital remote antenna unit transmits and receives second wireless signals over air interfaces.

Abstract: One embodiment is directed to an enterprise mobile network for providing wireless service within a coverage area associated with an enterprise using licensed radio frequency spectrum. The enterprise mobile network is configured to have local subscribers thereof. At least one local subscriber has assigned thereto a local mobile phone number and one or more other numbers (such as a PBX extension number, a public mobile phone number, and a Unified Communications end point). The enterprise mobile network is configured so that the local mobile phone number and one or more of the other numbers ring in response to incoming calls made to the local mobile phone number or the other numbers.

Abstract: Support for Session Initiation Protocol (SIP) devices is provided in an enterprise mobile network that provides wireless service within a coverage area associated with an enterprise using licensed radio frequency spectrum. In various embodiments, support SIP devices is provided by, for example, incorporating SIP user agent in a mobile switching subsystem or in a base station subsystem or by incorporating SIP server functionality into a mobile switching subsystem.

Abstract: One embodiment is directed to a system for providing wireless coverage and capacity for a public land mobile network within a building. The system comprises a pico base station comprising multiple transceiver units. The pico base station is installed in the building. The system further comprises a plurality of antennas located within the building. The plurality of antennas are located remotely from the pico base station. The pico base station is communicatively coupled to the public land mobile network. The pico base station is communicatively coupled to the plurality of antennas.

Abstract: One embodiment is directed to an enterprise mobile network for providing wireless service within a coverage area associated with an enterprise using licensed radio frequency spectrum. The enterprise mobile network includes a base station subsystem deployed on a premises of the enterprise to provide wireless capacity within the coverage area using the licensed radio frequency spectrum. The enterprise mobile network further includes a mobile switching subsystem deployed in an office of a service provider that operates a public land mobile network. The mobile switching subsystem is communicatively coupled to the public land mobile network. The base station subsystem is communicatively coupled to the mobile switching subsystem using an Internet Protocol (IP) network. The mobile switching subsystem is configured to function as a mobile switching center (MSC) and visitor location register (VLR) for roaming subscribers and local subscribers of the enterprise.

Abstract: A method for transporting wireless communication signals between a base station hotel and remote cell sites with separately digitized RF carrier signals is provided. Separately digitized carriers are transmitted over a digital network between the hotel and the remote sites, remaining in digital format until reaching terminal antenna units. At the antenna units, downlink digital signals are converted to analog RF signals and transmitted, while uplink analog signals are received and converted to digital signals. A corresponding system comprising a base station hotel, at least one remote site, and a digital data network connecting the hotel to the remote site is provided. The hotel includes a plurality of base stations and a digital hub for interfacing the hotel to the network. The remote site includes a set of antenna units connected via a local data link to a network access node for interfacing to the network.
