摘要:
A system and method for synchronizing internal clocks of receiving stations of a locating system are described. A beacon transmits reference data packets at a known position. A first arrival time is compared to a second arrival time to determine a correlated arrival time data. The first arrival time is a time of reception of the reference data packets by a first receiving station, and the second arrival time is a time of reception of the reference data packets by a second receiving station. A linear polynomial fit is computed as a function of the correlated arrival time data and the first and second arrival times. Times of arrival of data packets at the first and second receiving stations is synchronized as a function of the linear polynomial fit.

A device may include a battery; a first component drawing a first current from the battery, the first current being below a threshold; and a second component drawing a second current from the battery. The second component indicates the entering of a low current mode for a predetermined time. The first component is allowed to draw a third current above the threshold for the predetermined time.

A system and method embeds text in a multicast transmission. An exemplary method comprises receiving non-voice data. The non-voice data is embedded within digitized voice data. The digitized voice data with the embedded non-voice data is wirelessly transmitted, by a computing device, as a multicast transmission to a plurality of mobile devices.

A system and method advises network solutions. The method comprises receiving a request for a service to be implemented on a network, determining at least one solution to implement the service utilizing existing network components of the network, and presenting the at least one solution to a user. The system comprises a database storing network data for a plurality of network components in a network, an input module receiving an input indicating a requested new service for the network, a solution module searching the network data and determining at least one solution to implement the new service on the network, and an output module presenting the at least one solution to a user.
摘要:
A method that enables the power saving frame transmission comprising an AP informing a plurality of stations within its range in a WLAN about a plurality of scheduled service periods during which the AP has access to a channel in a scheduled service time, receiving the information about the plurality of scheduled service periods by the plurality of stations and deciding about initiating or not initiating a frame transmission, whether or not an acknowledgement and an immediate response expected from other APs pertaining to said WLAN are received prior to a subsequent scheduled service time, wherein the frame is transmitted in a cooperative frame transmission scenario.

摘要:
Described is a method and system for fast roaming of a mobile unit in a wireless network. An access point receives a packet from a wireless computing unit which includes unit identifying data and an association request to establish communications via the access point. The packet is processed to initiate an authentication procedure of the unit using the unit identifying data. The authentication procedure is performed by at least one of the access point and an authentication server connected to the access point. Wireless transmissions of further packets between the unit and the access point (e.g., the further packets being related to the authentication procedure) are prioritized. The authentication procedure is completed to determine if the association request of the unit be granted.
摘要:
A method, comprising the steps of appending a data packet to a data stream queue (“DSQ”), the DSQ having a priority level, allocating a quantum of bandwidth to the DSQ and transmitting the data packet as a function of the priority level and the quantum of bandwidth.
