Abstract: A wireless movable device, a system comprising the movable device, and a method for operating the movable device, wherein the movable device determines the link and channel quality of a link between itself and an ad-hoc device, such that the movable device is adapted to determine when it has traveled too far from the ad-hoc device to maintain a reliable link to the ad-hoc device, and wherein the movable device, upon determining the loss of a reliable link to the ad-hoc device, seeks out a location at which a reliable link exists with the ad-hoc device or with another ad-hoc device.

Abstract: An ad-hoc, peer-to-peer radio access system having a series of remote terminals, where each remote terminal is capable of forming a node, or hop, of the routing of a call made by one of the series of terminals. The call is routed along a routing path of terminals based on the class-of-service. If the call to be transmitted is a voice call, then a routing bath having low latency will be selected. If the call is a video transmission, then a routing path of low bit-error without excessive latency will be chosen. If the call is a data transmission, then the least-energy routing path will be chosen.

Abstract: An ad-hoc, peer-to-peer radio access system for cellular communications systems using time division duplex as a way of maximizing the bits/hz/km2 for cellular systems. The network architecture of the ad-hoc system allows the radio access to be integrated with the fixed components of a conventional cellular system, PSTN or ISP. The objective is to make the system of the invention transparent to the features and services provided by the external network. The advantages of such a system to a cellular operator are that significantly less infrastructure is required, and that the RF spectrum is more efficiently utilized resulting in much lower building and operating costs. The system architecture is comprised of remote terminals, routers, gateways, and at least one gateway controller that interfaces the ad-hoc system to a cellular network system. The ad-hoc system of the invention allows for both voice and data transmissions and receptions.

Abstract: A system and method for evaluating at least one communication link between a transmitting node (102, 106, 107) and a receiving node in a communications network (100), such as a wireless ad-hoc communications network (100) in accordance with the 802.11 standard. The system and method perform the operation of assigning respective link quality values to the respective communication links based on a transmit power level (TPL) value at which the respective data packets were transmitted by the transmitting node (102, 106, 107) over the respective links, a received sensitivity (RS) value of the receiving node (102, 106, 107) receiving the data packets, and a receive signal strength indication (RSSI) value provided by the network (100) for each respective link. The system and method can examine a content of a data packet being sent between the two nodes (102, 106, 107) to determine the TPL, and can receive the RSSI value from a physical layer of the communications network (100).

Abstract: A system and method for allowing network users to securely administer and deploy network nodes (102). These networks (100) may comprise wired and/or wireless connections. Examples would include wired networks (104) with shared infrastructure in an office building, as well as ad-hoc multi-hopping peer-to-peer network applications for the home. The system and method provides a key (130) that allows new nodes (102) and thus new devices (124, 126, 132) to gain access to a network (100) via an existing node (122) of that network (100).

Abstract: A system and method for providing position information of mobile user terminals (103) in a portable voice and data wireless communications network, such as an ad-hoc wireless communications network (100). More particularly, the present invention relates to a system of locating persons or assets using a centralized computing device, such as a server (125), that computes the respective locations of the terminals (103) from the respective information provided by the terminals (103) relating to their respective locations. A graphical display (121) that retrieves the location information from the centralized server (125) and generates a graphical display (121) of the location of all or selected terminals (103) based on their locations as computed by the server (125).

Abstract: An ad-hoc, peer-to-peer radio access system having a series of remote terminals, where each remote terminal is capable of forming a link, or hop, of the routing of a call made by one of the series of terminals. The status of the battery of each terminal which may potentially form part of the routing path of a call is reported to other terminals, whereby the routing path for a call will be decided also based on the status of the battery-charge of each terminal along the routing path.
