Abstract: A system for location of assets on a premises is described. The system uses an RFID tag which is attached to an asset to be tracked. The system also employs an array of RFID tag readers placed in known locations within the premises. Each RFID tag reader activates and obtains tag information from a passing tag. The system also includes a control logic. The control logic reads information from the array of RFID tags and the control logic triangulates the position of each tracked asset.

Abstract: A system and techniques for managing power utilization in a wireless local area network are disclosed. The system can utilize an infrastructure power management module that is configured to identify and power down one or more unused wireless devices and/or dynamically reconfigure the wireless operation of one or more wireless devices to consume lower power while still operating according to network requirements.

Abstract: Described is a system comprising a first wireless device and a second wireless device. The first device has access to a packet routing table which includes data indicative of a packet transmission path in a wireless mesh communications network. The second wireless device is communicatively coupled to the first device and has access to the routing table. Upon receipt of a packet by the first device which is addressed to the second device, the first device determines, as a function of at least one of (i) the routing table and (ii) a first identifier of the second device, a second identifier of a third wireless device to receive the packet directly from the first device. At least one of the first, second and third devices updates the routing table.

Abstract: In a network comprising a wireless device, a first access point (AP) and a plurality of neighbor APs, a method is provided for reducing the chances of packet loss when the wireless device roams from the first AP to one of the neighbor APs. For example, when the first AP is transmitting a particular packet of a packet stream from to the wireless device, the wireless device begins to move away from the first AP toward at least one of the neighbor APs. The first AP maintains an acknowledgement counter for the particular packet which counts a number of times the particular packet has been transmitted by the first AP without receiving an acknowledgement (ACK) message from the wireless device confirming successful reception of the particular packet from the first AP. The first AP determines whether an ACK message was received for the particular packet, and if not, the first AP determines whether the number of times the particular packet has been sent is equal to a particular number of attempts.

Abstract: A wireless local area network audio and video communication system with mobile units is provided, wherein mobile units are operated in a power saving mode and become active at selected intervals corresponding to the duration of audio and video signals forming audio and video data packets. In a preferred arrangement the mobile units have a digital signal processor that operates at different clock rates during different portions of the intervals.

Abstract: Described is a method for transmitting a voice packet from a first access point (“AP”) to a mobile unit (“MU”), forwarding the voice packet from the first AP to a second AP when acknowledgement of receipt of the voice packet is not received by the first AP and transmitting the voice packet from the second AP to the MU. Also, a system having a first access point (“AP”) transmitting a voice packet to a mobile unit (“MU”) and forwarding the voice packet when acknowledgement of receipt of the voice packet from the MU is not received by the first AP and a second AP receiving the forwarded voice packet from the first AP and transmitting the voice packet to the MU.

Abstract: A method for allowing time multiplexing in a wireless network comprising two or more access port and a wireless switch includes receiving a time ordered sequence comprising a plurality of time slots from the wireless switch. Next, the signals are transmitted according to the time ordered sequence. In another embodiment, an access port used in a wireless network that includes a wireless switch comprises a transceiver operable to receive a time ordered sequence comprising a plurality of time slots calculated by the wireless switch. Further the access port comprises a plurality of antennas coupled to an antenna selector; the antenna selector configured to couple selectively the transceiver with at least one of the plurality of antennas based at least in part on the time ordered sequence.

Abstract: A method of connecting a client on a moving carrier wirelessly to any stationary access point in a list of stationary access points in a predetermined order. The method includes authenticating the client to a first stationary access point in the list of stationary access points. The method includes identifying the client as an authenticated client and informing other access points in the list of stationary access points with respect to the authenticated client. The method includes bypassing an authenticating process when establishing network connections between the authenticated client and one of the other stationary access points.
