Abstract: Embodiments disclosed in the detailed description include supporting an add-on remote unit(s) (RU) in an optical fiber-based distributed antenna system (DAS) over existing optical fiber communications medium using radio frequency (RF) multiplexing. An existing DAS comprises at least one existing head end equipment (HEE) communicatively coupled to a plurality of existing RUs through an existing optical fiber communications medium. In aspects disclosed herein, an add-on RU is added to the existing DAS to support additional wireless communications. No new optical fibers are required to be deployed to support communications to the add-on RU in the existing DAS. Instead, the existing DAS is configured to support the add-on RU through the existing optical fiber communications medium using RF multiplexing. As a result, the add-on RU can be added to the existing optical fiber-based DAS without adding new optical fibers, thus leading to reduced service disruptions and deployment costs.

Abstract: Power management in a distributed communications system, such as a distributed antenna system (DAS), that includes determining user activity at remote units of the DAS. When user activity in one or more remote units falls below or above a specified threshold, power usage by the one or more remote units is reduced or increased accordingly. The power usage may reduced and/or increased by turning select remote units on or off, by increasing or reducing an operating voltage of one or more power amplifiers, and/or by turning select multiple-in, multiple-out (MIMO) front ends on or off. Power may be reduced such that wireless coverage within a specified area is maintained.

Abstract: A system and method of creating textual content from audio streams is present. The system can include a computing device configured to receive audio streams containing speech and identify the different speakers in the speech. The system breaks apart an audio stream into separate audio streams using speaker diarization and each audio stream is sent separately to a speech-to-text transcriber. Each audio stream includes only the speech of a single speaker, which is more easily converted into text by the speech-to-text transcriber. The text streams can be assembled into a transcript of the speech portions of the audio stream. A web page of the transcript can be published. High frequency words in the transcript can be tagged in the metadata of the web page to assist search engines and increase the value of the web page.

Abstract: Embodiments disclosed in the detailed description include supporting an add-on remote unit(s) (RU) in an optical fiber-based distributed antenna system (DAS) over existing optical fiber communication medium using wavelength division multiplexing (WDM). An existing DAS comprises at least one existing head end equipment (HEE) communicatively coupled to a plurality of existing RUs through an optical fiber communication medium. In aspects disclosed herein, an add-on RU is added to the existing DAS to support additional wireless communications. No new optical fibers are required to be deployed to support communications to the add-on RU in the DAS. Instead, the DAS is configured to support the add-on RU through the existing optical fiber communication medium using WDM. Thus, the add-on RU can be added to the existing DAS without adding new optical fibers, thus leading to reduced service disruptions and deployment costs.

Abstract: The invention is directed to a method and system for supporting wireless RF services over a wired digital data network infrastructure, such as an Ethernet network. The system includes a control unit that can be connected to a base station that supports one or more wireless RF services. The control unit converts the wireless RF signals to an intermediate frequency (IF) that does not interfere with the data network signals and combines the IF signals onto the cable run to a remote network device on the digital data network. The remote network device includes a multiplexer or a low pass filter and a high pass filter that separates the IF signals from the digital data signals on the downlink and combines the IF signals with digital data signals on the uplink over the cable run. The IF signals can be input to an RF module connected to the remote network device which converts the IF signals back to the original RF signals for transmission by a transceiver to wireless devices.

Abstract: A method and system to connect remote antennae and/or remote cellular sectors/sites to cellular base stations. The method and system described herein uses bi-directional optical wireless links, which transfer the information between the base station and the remote site, and vice versa, by single optical signal or several optical signals of different wavelengths. This method and system make it possible to place the antennae remote from the base station.

Abstract: An apparatus and methods for sharing communications infrastructure between multiple network operators. In one example, a shared network includes a first infrastructure of a first operator, a second infrastructure of a second operator, and a first remote antenna of the first operator disposed on the second infrastructure and coupled to the first infrastructure by a communication link. The communication link may be a wireless optical link between the first remote antenna and the first infrastructure.
