A hybrid cellular and non-cellular multi-hop communication device, including a hand-held wireless device having one or more antennas, a cellular wireless interface connected to at least some of the one or more antennas, and a non-cellular wireless interface connected to at least some of the one or more antennas. The non-cellular wireless interface may include a rate allocator configured to select a physical-layer rate of transmission of data from the non-cellular wireless interface based on a queue length of data to be transmitted from the hand-held cellular device and a transmitter configured to wirelessly transmit data from the queue and adjust physical-layer transmission parameters based on a physical-layer rate selected by the rate allocator.

Methods and apparatuses for relaying data in wireless networks

The subject matter describes software, devices, networks, and methods to configure a wireless device to establish two or more concurrent wireless links in a wireless network. Embodiments disclosed herein relate to use of computing and communication resources to perform multi-hop wireless communication and to expand the coverage of cellular networks.

Concurrent uses of interfaces for participating in wireless networks

The subject matter describes devices, networks, systems, media, and methods to create secure communications between wireless devices and cellular networks, where the wireless devices communicate with the cellular networks via multi-hopping methods in wireless networks.

Methods and systems and secure connections for joining wireless networks

A method, system, or computer program product to enhance the performance of multi-hop cellular networks or other wireless networks is provided. A wireless device (e.g., cellular telephone) is able to communicate with a base-station in a cell of the cellular network over a non-cellular interface via another wireless device in the cell through the use of multi-hopping. By enabling wireless devices to communicate with a base station in such a manner, the effective coverage area of the cellular network is expanded and the effective capacity of the cellular network is improved. Distributed routing, device management, adaptive scheduling, and distributed algorithms can be used to enhance the overall performance of multi-hop cellular networks.

Network routing system, method, and computer program product

Described herein are devices, networks, systems, media, and methods used to collect WT information and to alter, based on or taking the collected information into consideration, one or more parameters used to control a mode of operation in which WTs decide to operate. In this way the relative portions of WTs operating in a first or second mode in one or more regions can be automatically adjusted by a network control node modifying mode of operation control parameters which are then communicated to the WTs in the region in which the modified WT mode control parameter is to be used. The wireless terminals than make a decision as to the mode of operation in which to operate using the modified mode control parameter and one or more signal measurements or other information available to the WT making the mode of operation decision.

Methods and apparatus for collecting and/or using wireless communication related information to facilitate WT mode of operation decisions

The subject matter describes devices, networks, systems, media, and methods to create secure communications between wireless devices and cellular networks, where the wireless devices communicate with the cellular networks via multi-hopping methods in non-cellular networks.

Methods and systems and secure connections for joining hybrid cellular and non-cellular networks

Methods and apparatus for efficiently establishing communications connections, e.g., for a secondary application, are described. A device to device communications network has established routing paths, e.g., corresponding to a first application. Different segments of the network use different gateways. Individual communications devices within a segment of the network may have incomplete information on the routing within the segment. A wireless communications device advertises the gateway device which it uses for the first application. A first communications device seeking to establish a communications connection with a second communications device for a second application uses obtained gateway information to make transmission and/or routing decisions, e.g., identifying a third communications device which can bridge a routing path gap between two segments of the network.

Network methods and apparatus

Distributed rate allocation and collision detection in wireless networks

The subject matter describes software, devices, networks, and methods to configure a non-cellular interface of a wireless device to establish two or more wireless links in a hybrid of cellular network and a non-cellular network. The advantage of concurrent uses of non-cellular interfaces maximizes the use of computing and communication resources to perform multi-hop communication and to expand the coverage of cellular networks.

Concurrent uses of non-cellular interfaces for participating in hybrid cellular and non-cellular networks

Methods and systems of secure connections for joining hybrid cellular and non-cellular networks

Methods and apparatus for efficiently communicating network connectivity information in a communications system are described. Two types of signals with different characteristics, e.g., long range synchronous beacons, e.g., LTE-D beacons, and short range asynchronous beacons, e.g., WiFi beacons, are used in combination to advertise network connectivity information and accelerate the acquisition of a routing path for a communications device to a device serving as a gateway for a infrastructure network. Reception of a first type signal triggers monitoring for a second type signal, and a received second type signal communicates information used to determine a communications path to a gateway device.
