| 141 | Control of low power wireless networks for power conservation | US11652399 | 2007-01-11 | US20070165545A1 | 2007-07-19 | Patrick Dobrowski; Eric Lovegren; Kelly Orth; Kyle Stotz |
| A wireless mesh network routes messages between a host computer and a plurality of field devices. The mesh network is synchronized to a global regular active schedule that defines active periods when messages can be transmitted or received by nodes of the network, and inactive periods when messages cannot be transmitted or received. Based upon messages to be sent by the host computer to selected field devices, the network is controlled to selectively maintain active those nodes required to route messages to the selected field devices. Those required nodes are maintained in an active state as long as communication with the selected field devices continues, while other nodes are allowed to return to a low power inactive state. When communication between the host computer and the selected field devices is no longer required, the entire network is allowed to enter the low power inactive state. | ||||||

| A control system uses a wireless mesh network to provide communication between a host computer and field devices. Performance of the wireless mesh network is monitored by collecting network performance data from each node, such as the nodes with which it is communicating, received signal strengths over links to different nodes, the number of errors occurring on each link, and how frequently communication is occurring with each of the other nodes. A visual network map is generated using performance statistics based on the data gathered from the nodes of the wireless mesh network. The visual network map allows a user to determine the routes that messages take through the wireless mesh network, diagnose potential problems, and make adjustments to improve network performance. | ||||||

| After a first wireless terminal device transitions to a Direct Link Protocol mode, the terminal device transmits an ICMP_echo_request signal directly to a second wireless terminal device and, upon receiving an ICMP_echo_reply signal from the second wireless terminal device within a fixed period of time, counts up the number of times there is a reply. If the ICMP_echo_reply signal is not received within a fixed period of time, then the first wireless terminal device counts up the number of non-replies. As a result, the first wireless terminal device can readily judge whether it is capable of communicating directly with the second wireless terminal device in the Direct Link Protocol mode. | ||||||

| 152 | System and method for avoiding triangulation delay in a telecommunications network | US10020632 | 2001-12-13 | US06901258B2 | 2005-05-31 | Purva R. Rajkotia |
| For use in a telecommunications network comprising a plurality of packet data service nodes and a plurality of mobile stations, wherein each packet data service node is capable of communicating with one or more mobile stations, there is disclosed an apparatus and method for avoiding triangulation delay that is caused by sending messages over a long network path. The apparatus comprises an interface between the packet data service nodes. Information sent over the interface permits a first packet data service node to send data packets of a message from a first mobile station to a second mobile station directly from the first packet data server node to a second packet data server node without accessing an Internet (IP) protocol network. This avoids triangulation delay by decreasing the length of the network path for the message. | ||||||

| 157 | Wireless switch for use in wireless communications | US10449630 | 2003-05-30 | US20030227914A1 | 2003-12-11 | Hung Nguyen |
| The present invention is related to a switch for use in wireless communication systems. In one embodiment, the switch can concurrently process data from multiple mobile stations and supports full duplex, i.e., allowing receiving and transmitting data at the same time. The switch can concurrently communicate with other switches and/or mobile stations in the basic service set (BSS) of that switch. A switch may be considered an access point commonly used in other approaches. However, systems using the switch do not need to use an Ethernet switch commonly found in WLAN communication systems that use access points. Switches may be set up in a master-slave scheme wherein a master switch communicates with its slave switches, and slave switches communicate with one another through the master switch. If the data is for a mobile station in the same BSS of the switch, then, via a switch controller, the switch passes the data from the receiving path to the transmitting path. As a result, the data does not have to travel out of the switch and then back to the same switch again. | ||||||
