Abstract: Multi-channel network communication is improved by reducing the amount of data that is transmitted over connections that can stem from a similar source. Content of data packets transmitted from the source are reduced and the result is compared to previously transmitted data packets. If identical packets are found, then only an identification of the packet is transmitted. At the receiving side, the identification is used to identify a previously received data packet and use that as though it was the recently received packet. If a similar packet is identified, then the identification of the similar packet, along with change information is transmitted to the receiving side.

Abstract: A standard time and frequency signal receiver receives a time code in which a plurality of data pulses “1”, “0” and “P” which are identified by width are arranged one in a respective one of unit periods of the standard signal. An amplitude of a detected signal of the time code is sampled with respect to a seconds synchronization point in a unit period. Then, correlation values F1, F0 and FP for the data pulses “P”, “1” and “0”, respectively, are calculated based on the sampled values. These correlation values F1, F0 and FP are then compared to determine the data pulse received. Even when the time code contains a considerable noise, which of the “1”, “0” and “P” signals was received is determined accurately, thereby achieving the reception of the time code with a reduced error.

The system has a number of distributed communication nodes, each node being arranged for communicating frames of data with the other nodes during both the static (11, 12, 13 . . . ) and the dynamic (51, 52, 53 . . . ) communication slots. Each node includes a synchronized time base 5 made up of consecutive timeslots (11, 12, 13 . . . , 51, 52, 53 . . . ). The timebase 5 has substantially the same error tolerance in each node. For static communication (10), a predetermined number of timeslots (20) are utilized for each static communication slot. For dynamic communication a dynamically allocated number of timeslots (60) are utilized for each dynamic communication slot. In this way both static and dynamic media arbitration is provided within a periodically recurring communication pattern.

Abstract: During each node's awake period, each node multicasts the relative time or slot of their next awake period (beaconing interval) to all neighboring nodes. This enables each node to intelligently and independently schedule the time slot of its next transmission based on the beaconing intervals of the nodes it has heard from. During each active (awake) interval, a node builds statistics of the future transmission/receive times of its neighbors and uses them to determine its next transmission time. In one proposed implementation, at the end of an active interval, a node picks the time slot with the highest counter for its next transmission. In another proposed implementation, at the end of an active interval, a node picks one of the slots with a weighted probability; the weight of each slot is proportional with the value of the counter associated with the slot.

Abstract: A method and system reduce interference between overlapping first and second wireless LAN cells in a medium. Each cell includes a respective plurality of member stations and there is at least one overlapped station occupying both cells. An inter-cell contention-free period value is assigned to a first access point station in the first cell, associated with an accessing order in the medium for member stations in the first and second cells. The access point transmits a beacon packet containing the inter-cell contention-free period value, which is intercepted at the overlapped station. The overlapped station forwards the inter-cell contention-free period value to member stations in the second cell. A second access point in the second cell can then delay transmissions by member stations in the second cell until after the inter-cell contention-free period expires.

A different uplink wireless transition resource is allocated for the talk-spurt state vs. the silence state.
