Title: System and method for time synchronization in a wireless network

Abstract

A system includes multiple wireless nodes forming a cluster in a wireless network, where each wireless node is configured to communicate and exchange data wirelessly based on a clock. One of the wireless nodes is configured to operate as a cluster master. Each of the other wireless nodes is configured to (i) receive time synchronization information from a parent node, (ii) adjust its clock based on the received time synchronization information, and (iii) broadcast time synchronization information based on the time synchronization information received by that wireless node. The time synchronization information received by each of the other wireless nodes is based on time synchronization information provided by the cluster master so that the other wireless nodes substantially synchronize their clocks with the clock of the cluster master.

Synchronization system and method for wireless communicating nodes

Patent Armstrong, Brian S. R.; Pereira, Luis R.; Rentel, Carlos H.

A system includes first and second wireless nodes having a clock with plural times, a wireless transceiver, and a processor cooperating with the transceiver to transmit and receive packets. The second node transceivers wirelessly communicate with the first or other second node transceivers. The second nodes include a Kalman filter with an output, plural filter gains, and an input representing the difference between: about the time of the clock when a received packet should have ideally been received, and a time when the received packet was actually received as measured by the clock. A circuit provides dynamic adjustment of themore » « less

Channel hopping method of interference avoidance for a wireless communication network and wireless communication system employing the same

Patent Rentel, Carlos H.; Pereira, Luis R.; Gutierrez, Jose A.

A wireless communication system includes a wireless master node having a plurality of channels, and a number of wireless slave nodes having a plurality of the channels. The master node and the slave nodes are structured to wirelessly communicate over a particular channel. The master node and the slave nodes are structured to decide to hop to a different channel. The master node and the slave nodes are structured to select: (a) the different channel, in order to be as far away as possible from a number of the channels, which are known to cause interference to wireless communications betweenmore » « less

System and method for selective transmission and reception for stationary wireless networks

Patent Bhuyan, Arupjyoti

A system and methods for selective transmission and reception for stationary wireless networks. The system and method include an end user equipment, a primary base station, a core network, and a selective server. The end user equipment transmits a request for transmission to the primary base station receiver. The primary base station authenticates the end user equipment using a cellular network authentication process. The primary base station then searches for a time slot data for the end user equipment from the selective server and determines whether the time slot is open for transmission, steers a beam towards the end usermore » « less
