The disclosure provides for a system that includes a network controller. The network controller is configured to receive information from nodes of a network, where nodes include one node that is in motion relative to another node. The network controller is also configured to generate a table representing available nodes and possible links in the network based on the information, and determine a topology of the network based on the table. Additionally, the network controller is configured to receive client data information from a client device, and determine flows for the topology based on the client data information. Each flow includes one or more requirements for a routing path through the network. The network controller is configured to generate a network configuration for the topology based on the flows, and send instructions to the nodes of the network for implementing the network configuration and transmitting client data.

A method and system creating a distributed network suitable for transferring information between devices. In particular, the present disclosure relates to power generating server devices designed to act as nodes within a distributed network. Specifically, the present disclosure provides specialized devices designed to generate power using solar panels to power servers that are capable of operating as nodes within a distributed network.

The invention relates to base stations in communication networks. In more particular the invention relates to cellular base stations such as 3G/4G and WLAN base stations. Some or all of the aforementioned advantages of the invention are accrued with a fully photonic base station (200) that powers itself with solar photons, provides radio network access and relays an optical photonic beam (220, 221, 230, 231) through air encoded with the data from radio signals of computer users and mobile phone users to the Internet and the global telecommunication network. A system engineer can build a network with the inventive base stations in a matter of days. He simply walks to the roof of houses and points the optical beams to other base stations in adjacent houses.

A system for transmitting wireless power from multiple sources to multiple receivers, in which the safety of the system is maintained in spite of the possibility that two beams may intersect in the transmission space, thereby generating power or power density levels which exceed those at which the safety mechanisms of the system were designed to operate. The paths of the beams are known from the transmission positions and directions, and from the positions and orientations of the receivers, as measured by positioning devices on them. When an intersection, or near intersection of beams is determined, the system is triggered to reduce the safety risk by attenuating or turning off, or by diverting, one or more of the beams. In addition, since a reflected beam's path may not be readily discernable, the system can ascertain if one of the beams has undergone a reflection, by looking for displayed mirror images.

An uplink transmission band and a downlink transmission band that are allocated to each of a plurality of users are determined based on allocation information indicating allocation of a frequency bandwidth available to each of the plurality of users, and are output as uplink transmission band allocation information and downlink transmission band allocation information, respectively. Based on the downlink transmission band allocation information, downlink signals output from a plurality of wireless control devices toward a plurality of wireless devices for each of the plurality of users, and the uplink transmission band allocation information are multiplexed, and the multiplexed signal is demultiplexed into downlink signals for each of the plurality of users and the uplink transmission band allocation information. Based on the demultiplexed uplink transmission band allocation information, the uplink transmission band allocated to each of the plurality of users is changed, and uplink signals output from the plurality of wireless devices toward the plurality of wireless control devices for each of the plurality of users are multiplexed according to the changed uplink transmission band and then, the multiplexed signal is demultiplexed into the uplink signals for each of the plurality of users.

Architectures and techniques are presented that improve or enhance a network planning procedure such as by selecting a more efficient test buffer that is used to identify objects that might intersect a Fresnel zone between two transceivers. An improved test buffer (e.g., buffer region) can be one that is constructed from a plurality of rectangles situated along a line of sight of the two transceivers and that are oriented according to cardinal directions.

A method for establishing a free-space data transmission channel between movable and/or spatially fixed network nodes. Dynamic position information is collected regarding movable network nodes and static position information relating to spatially fixed network nodes. Specific and node-dependent parameters for the fixed network nodes is collected, based on collected dynamic and static position information. A prioritization list is created of the fixed network nodes. Checking occurs, for the network node having the highest priority of the multiplicity of movable or spatially fixed network nodes in the created prioritization list, which of a selection of movable or spatially fixed network nodes are possible for setting up a directional free-space data transmission channel with the network node having the highest priority of the fixed network nodes. A directional free-space data transmission channel is set up.
