摘要： A system and method for improving the ability of a portable voice and data wireless communications network to provide position information regarding mobile nodes located within a network (figure 1). The system and method employs mobile access points (101), wireless routers (102), and mobile nodes (103), which each contain at least one transceiver, and are mounted or dispersed at a geographic location. Access points can be connected to mobile vehicles, or connected to a network management system, and wireless routers can be mounted to portable stands for easy deployment. Mobile nodes can be attached to equipment or personnel for tracking purposes, and each node includes technology which may determine an absolute node location containing latitude, longitude and altitude of a node, or a relative node location containing the distance and angle between nodes, or a combination of both absolute and relative location data.

摘要： A system and method for evaluating at least one communication link between a transmitting node and a receiving node in a communications network, such as a wireless ad-hoc communications network 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 over the respective links, a received sensitivity (RS) value of the receiving node receiving the data packets, and a receive signal strength indication (RSSI) value provided by the network for each respective link. The system and method can examine a content of a data packet being sent between the two nodes to determine the TPL, and can receive the RSSI value from a physical layer of the communications network. Accordingly, the system and method can determine which link that additional data packets are to be sent by the transmitting node to the receiving node via the communication link based on the link quality values. Specifically, the link having the highest link quality value is selected.

摘要： A system and method for improving the ability of a wireless packet switched data communications network (Fig. 1) to provide service to mobile user terminals (118). It employs a mobile access point (132) adapted to provide a mobile wireless user terminal (118) with access to packet-switched communications network. Mobile access point (132) can be mounted to a mobile vehicle (146) and receives substantially constant power fom the vehicle and is adapted to transmit and receive communications signals to and from wireless user terminals (118), fixed access points (106 and 108) and other networks (124, 128, 148, 150, and 152) and wireless terminals (118). Mobile access point (132) includes at least one or more transceivers supporting multiple wireless communication protocols.

摘要： A system and method for achieving enhanced CSMA/CA which improves channel availability and quality of service (QoS) in a wireless communications network. The system and method establish channels to enable communication between nodes in a communication network, based on the relationship between the average time length of message data packets and the time lengths of the request to send and clear to send messages. A node of the communication network places a data packet at a location in a queue for retransmission based on a type of information contained in the data packet if the destination node for which the data packet is intended is unable to receive the data packet. The location in the queue is indicative of a duration of time that the node will delay before attempting to resend the data packet to the destination node.

摘要： 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.
