Policies that govern allocation of spectrum access credentials are established. The policies are configured to implement regulatory rules governing spectrum use in a geographic area. Policy establishment includes selecting, from a collection of predetermined general policy constructs that are generic to plural regulatory domains, general policy constructs to transform into protection instances. Policy parameter inputs are applied to policy parameter fields of the selected general policy constructs to establish the protection instances, the protection instances specify how regulatory rules are applied in the geographic area. Protection data values are applied to protection data fields of the protection instances to create instances of policies that are specific to the geographic area according to incumbent spectrum use in the geographic area.

System and method for spectrum sharing management using dynamic spectrum policy enforcement

Spectrum that is shared by two or more radio devices that operate near a boundary of a tract is managed by a spectrum management system. The system determines a closest point of approach to the boundary for each radio device and an aggregate contributed power at each closest point of approach by the emissions from the radio devices previously granted spectrum access to the shared spectrum. A transmit power limit for the requesting radio device is determined at each closest point of approach. Spectrum access is granted to a requesting radio device and the granted spectrum access includes an authorized transmit power limit that does not exceed the smallest one of the transmit power limits.

System and method for managing RF signal aggregation at geo-tract boundaries

Managing spectrum use in a managed area where spectrum use is carried out by an incumbent user on an intermittent basis includes sensing spectrum use in the managed area and determining that the incumbent spectrum user is actively using spectrum in the managed area by analyzing sensor data. A spectrum use policy associated with characteristics of the determined spectrum use is made and one or more secondary spectrum users are notified that spectrum defined in the identified policy is unavailable for use by the one or more secondary users.

System and method for policy-based spectrum management

A spectrum management server generates and an electronic device uses a channel map solution for a predetermined travel route of the electronic device. The channel map solution includes at least one available channel for each of the plural geographic areas through which the planned travel route passes. At least two adjacent ones of the geographic areas have different channel availability.

Systems and methods for determining and specifying spectrum availability for a predetermined travel route

Systems and methods to facilitate acquisition of specific operating parameters by a spoke radio device via a hub radio device while the hub radio device operates using specific operating parameters and the spoke radio device operates using generic operating parameters. The spoke radio device may acquire the generic operating parameters from a beacon broadcast by the hub radio device. If a link between a hub radio device and a spoke radio device cannot be satisfactorily established and maintained using the specific and generic operating parameters, respectively, then the hub radio device may use alternative channels and/or reduce its operational area to attempt to converge specific and generic transmit power levels for improved link establishment.

System and method for optimizing channel characteristics when initializing links between cognitive radios in a shared spectrum environment

Allocating spectrum to a secondary radio device includes determining a contour separation distance for the secondary radio device. The contour separation distance is a function of a minimum separation distance from protected areas of primary radio devices and an accuracy variance for the secondary radio device. The accuracy variance is specified as a distance and is a function of accuracy information for a reported location of the secondary radio device. If a distance between a contour of a protected area for a primary radio device and the reported location for the secondary radio device is less than the contour separation distance, a channel used by the primary radio device is not available for use by the secondary radio device for wireless communications. Otherwise the channel used by the primary radio device is available for use by the secondary radio device for wireless communications.

System and method for allocating spectrum using dynamically adjusted separation distances for mitigating interference

Spectrum that will become venue-protected in the future is made available to radio devices by a central control system with which the radio devices requests spectrum access information for use in wireless communication. The central control system establishes a re-request time duration specified in an amount of time that will elapsed at or before the spectrum becomes protected. The elapsing of the re-request duration serves as a command to the radio device to transmit a new channel request to the central control system.

System and method to facilitate time management for protected areas

A system and method for automatically configuring operating parameters of a wireless radio device. The wireless radio device determines a geographic location of the wireless radio device, and a determination is made as to the regulatory domain in which the wireless radio device is located based on the geographic location of the wireless radio device. The wireless radio device may register with and/or receive configuration information from the server associated with the regulatory domain in which the wireless radio device is located. The wireless radio device configures the operating parameters of the wireless device in accordance with configuration parameters associated with the determined regulatory domain.

Support for wireless radio device in multiple wireless regulatory domains

Techniques are provided for reliably distributing network management information in and ad hoc multi-hop wireless network which includes a number of existing nodes. A first node selects a particular timeslot in a dedicated channel based on the network management information received from the neighbor nodes and determines, via a contention channel, if the particular timeslot is being used by any neighbor nodes of the first node. If the particular timeslot is determined to be unused, then it is assigned to the first node for periodically transmitting network management information.

System, method and apparatus for reliable exchange of information between nodes of a multi-hop wireless communication network

Systems and methods of providing network access information from one or more servers to a wireless device. The wireless device acquires information from the servers about available networks at a current location of the wireless device. The network information is based on a plurality of device parameters, network parameters and regulatory requirements that govern the operation of the wireless device. In addition, the wireless device may assess the acquired information for suitability for communications to be carried out by the wireless device.

System and method for providing network access to electronic devices

A system and method for enabling a mobile user terminal in an ad-hoc packet-switched wireless communications network to selectably operate as a router for other mobile user terminals in the network based on certain criteria. The user terminal comprises a transceiver and a controller. The transceiver is adapted to transmit wireless communications data, such as packetized data, addressed to a destination user terminal, to at least one other user terminal for routing by that other user terminal to the destination user terminal. The controller is adapted to prevent the transceiver from transmitting the wireless communications data to that particular other user terminal based on routing data pertaining to an ability of the other user terminal to route said wireless communications data to the destination user terminal. The user terminal further includes a memory for storing the routing data received from the other user terminal, for example, in the form of routing table information, or from the wireless communications network.

A first time division multiplex (TDM) time slot is provided which is defined as a bi-directional channel for use in a TDM network including a source node and a destination node. The source node can transmit data to the destination node in a first portion of a first TDM time slot. In one implementation, a second portion of the same first TDM time slot can be reserved for the destination node to transmit information to the source node. The destination node can determine whether the data from the source node has arrived properly, and then transmit an indication message to the source node in the second portion of the same first TDM time slot to indicate whether the data from the source node has arrived properly at the destination node.

System, method and apparatus for determining if data from a source has arrived properly at a destination in a time division multiplex (TDM) communication network

A method and system for routing data in a wireless network () that enables all nodes () to find routes to each other even if the nodes () are non-meshed which are incapable of operating as a router to route packets received from other nodes (), and for associating and reassociating the non-meshed and meshed nodes with other meshed nodes (). The non-meshed nodes (STA-STA) request association with one of the meshed nodes (AP) which are capable of performing packet routing, to request that the meshed node (AP) with which the non-meshed node (STA) is associating operate as a proxy node to route packets between the associated non-meshed node (STA) and other meshed or non-meshed nodes (). Some of the meshed nodes () further operate as intelligent access points () to provide the non-meshed nodes (STA-STA) and other meshed nodes () with access to other networks, such as the Internet (), as well as to effect the association and reassociation of the non-meshed and meshed nodes ().

A communications network which is capable of effectively and efficiently handling mobility of wireless user terminals between access point nodes of a packet-switched network with minimal overhead and packet loss, and a method for using the same. The communications network employs a packet-switched core network and a plurality of access points coupled to the core network. Each access point is adapted to provide any user terminal with wireless communications access to the core network when that user terminal becomes affiliated with that access point. Each access point, as well as other nodes on the network such as a media server, DNS server and an IP gateway router, includes an address resolution cache which is adapted to store information representative of affiliation between the user terminals and the access points of the network. Each access point is adapted to deliver to the other access points a message indicating that a user terminal has changed its affiliation from another access point to that access point, to enable the other access points and core LAN nodes to update their respective address resolution cache based on the message. Preferably, an access point is adapted to issue the message over the core network as an address resolution request for an address, in particular, an IP protocol address, of the user terminal which has changed its affiliation to that access point.
