Transmitting radio signals using simultaneous retransmission

摘要

Disclosed is a simulcast approach to broadcasting a message from each device, or node, of a network. A source device, such as a wall switch, may broadcast a message that may be received by a plurality of devices, such as light bulbs, in a network. Each of the plurality of devices may receive the message at substantially the same time. In response to the message, the receiving devices may determine if the message is to be retransmitted. If the message is to be retransmitted, it may generate a modified message. Each of the plurality of devices may transmit the modified message substantially simultaneously. To maintain timing to the source device between the devices in the network, the message may be configured to facilitate synchronization of the clocks to a timing signal in the message.

1. A method comprising:
receiving by a first device a first message from a source device, the message including data identifying a destination device from among a plurality of devices in a wireless network; determining that the first device is an intermediary device; determining a timing of the reception of the first message; determining a time period for transmitting a modified message, after the determined timing of the reception of the first message, by summing a predefined duration of the first message with a predefined synchronization time period; synchronizing a clock of the first device to a predefined timing signal included with the first message; and transmitting, by the first device, a first modified message based upon the synchronized clock and the identified time period.
