Abstract: A system and method for arbitrating channel access in a wireless device including co-located network transceivers are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver. The first transceiver is configured for operation with a first wireless network. The second transceiver is configured for operation with a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic causes the first transceiver to transmit a notification signal indicating a time period during which the second transceiver of the wireless device will perform a first wireless transaction, and during which, based on receiving the notification signal, a different wireless device performs a second wireless transaction via the second wireless network without transmitting a notification signal.

Abstract: Embodiments of the invention include a method for creating probe requests. The method is used when positioning is required. A short probe request is constructed with SSID set to GPS SSID_NAME. Another method continues after a short probe response is received. It is determined if a SSID of the probe response matches the SSID of the short probe request. If it does send an ACK.

Abstract: A network includes a parent node and at least one child node configured to communicate with the parent node via a wireless network protocol. The parent node includes a broadcast coordinator to transmit a broadcast message from the parent node to the child node at predetermined time intervals according to the wireless network protocol. A scheduler generates a scheduling packet that is communicated in the broadcast message. The scheduling packet includes a data field to instruct each child node to activate and receive data communicated from the parent node in a prescribed time slot following the broadcast message that is defined by the scheduling packet.

Abstract: A system and method for reducing energy consumption in a wireless network. In one embodiment, a system includes a network coordinator configured to manage access to a wireless network. The network coordinator includes a controller. The controller is configured to define a channel hopping list that specifies on which channel a beacon signal is transmitted in each slot frame of the wireless network. The controller is also configured to set a number of time slots in each slot frame based on a length of the channel hopping list. The controller is further configured to transmit a first beacon signal in each slot frame on a channel specified by the channel hopping list. The number of slots in each slot frame causes the first beacon signal to be transmitted on a same channel in each slot frame.
