Method and system for capturing signals in accordance with allocated resources. One method includes receiving, from a server by a network interface of a first communication device located in a cell, identification information of a second communication device located in the cell. The method further includes receiving, from a base station by the network interface of the first communication device, a resource allocation message destined for the second communication device. The resource allocation message indicates a resource allocation for the second communication device on an uplink channel of the base station. The method further includes decoding, by an electronic processor of the first communication device, the resource allocation message using the identification information of the second communication device. The method further includes capturing, by the network interface of the first communication device, signals based on the resource allocation for the second communication device.

Systems and assemblies for providing both cellular and passive optical local area network (POLAN) data signals along a single, shared fiber optic backbone within an in-building network architecture are provided herein. Systems include a headend unit that combines data signals from a cellular network and optical line terminal (OLT) onto the fiber optic backbone, which is then connected to a series of daisy-chained fiber optic assembly units. An example fiber optic assembly unit includes an asymmetric coupler that splits an input fiber optic signal from the fiber optic backbone into an output fiber optic signal and a throughput fiber optic signal that is fed back onto the continuing fiber optic backbone. The output fiber optic signal is filtered into dense wavelength-division multiplexing (DWDM) channels for providing data signals to a wireless or cellular network and further split into multiple passive optical network (PON) outputs for a local area network (LAN).

Wavelength-based random access in an optical communications network for a wireless communications system (WCS) is disclosed. An optical network unit(s) (ONU(s)) is configured to generate a random access signal comprising an unsolicited buffer occupancy (BO) report to request uplink allocation as soon as the ONU(s) receives a non-periodic uplink data burst. The ONU(s) then sends an optical random access signal including the unsolicited BO report to an optical line terminator (OLT) based on a random access wavelength, which is so determined not to cause any interference with a downlink optical communications signal(s) and an uplink optical communications signal(s) being regularly communicated between the OLT and the ONU(s). As a result, it is possible to reduce access delay at the ONU(s) for sending the non-periodic uplink data burst without requiring frequent polling from the OLT, thus helping to reduce signaling overhead and improve throughput of the optical communications network.

Adaptive scheduling for periodic data traffic in an optical communications network for a wireless communications system (WCS) is disclosed. Herein, an optical line terminator (OLT) in an optical communications network is configured to dynamically adjust a scheduled start time(s) of a scheduled period(s) in a periodic schedule to help reduce a schedule misalignment to below a predefined threshold. More specifically, the OLT is configured to determine the schedule misalignment. Accordingly, the OLT can adjust the respective scheduled start time(s) of the scheduled period(s) based on a temporal step determined based on the determined schedule misalignment to reduce the schedule misalignment to below the predefined threshold. By adapting the periodic schedule based on the determined schedule misalignment, it is possible to reduce scheduling delays for communicating the periodic data traffic, thus making it possible for the optical communications network to support a time-critical application for improved user experience.

Methods and systems for merging isolated networks. One method includes determining that a second network is located within a predetermined distance of a first network. The method also includes exchanging content between a first network core of the first network and a second network core of the second network over a side haul communication channel. The exchange of content results in a first base station transceiver of the first network being capable of communicating with first network components of the first network core and with mirrored instances of second network components of the second network core within the first network core. The method also includes controlling, with the first network core, communications through the first base station transceiver using the second content included in the mirrored instances of the second network components.

A method and apparatus are provided for positioning an unmanned robotic vehicle (URV). The URV captures a set of one or more of image and non-image information of an object while positioned at a first position, provides the set of image/non-image information to a server entity, in response to providing the set of image/non-image information, receives a three-dimensional (3D) model associated with the object, autonomously determines a second position based on the 3D model, and autonomously navigates to the second position. At the second position, the URV may capture further image and/or non-image information and, based on the further captured image/non-image information, autonomously determine, and navigate to, a third position. The steps of capturing further image and/or non-image information and, based on the captured image and/or non-image information, autonomously determining and navigating to further positions may be repeated indefinitely, or until otherwise instructed.

A method and apparatus are disclosed for setting an initial transmit power level of a deployable network that overlaps in coverage with a WAN. Multiple transmit power levels are determined. For each transmit power level, a geographical coverage area of the deployable network at an incident is determined based on a signal propagation model, a first set of mobile devices is determined that are within the geographical coverage area and that are involved in responding to the incident, and a second set of mobile devices is determined that are within the geographical coverage area, that are not involved in responding to the incident, and that may be interfered with by transmissions of the deployable network. A transmit power level of the multiple transmit power levels then is selected as the initial transmit power level based on the first and second sets of mobile devices determined for each transmit power level.
