Abstract
A wireless communications system which provides improved power consumption and fast synchronization for low power and small footprint wireless devices is described. System and methods are described to provide a fast synchronization, low latency and efficient communications capability for services that sip data. That is services that exchange small amounts of data on an infrequent or sporadic basis, or data that is communicated in bursts with relatively large periods of inactivity in between.
Claims18
A method being performed by a wireless communications device, the method comprising transmitting an at least one sequence of data packets wherein:
- the at least one sequence of data packets further comprises an at least one first data packet type (FDPT) followed by an at least one second data packet type (SDPT);
- a counter is initialized prior to transmitting the at least one sequence of data packets;
- the counter is incremented by one after transmitting each data packet;
- each successive data packet transmission is separated by a transmission time interval from the last transmitted data packet;
- the transmission time interval is a constant time interval plus a random timing jitter that is randomly determined for each data packet;
- the information in each of the at least one FDPT comprises an identity of the wireless communications device, the constant time interval value, the counter value, and an indication that the at least one FDPT is a non-connectable Bluetooth Low Energy (BLE) advert;
- and
- the information in each of the at least one SDPT comprises an identity of the wireless communications device, the constant time interval value, the counter value, information on obtaining further data including a radio data channel and the transmit timing for an at least one further data packet, and an indication that the at least one SDPT is a non-connectable BLE advert.

- and
- the information in each of the at least one SDPT comprises an identity of the wireless communications device, the constant time interval value, the counter value, and an indication that the at least one SDPT is a connectable BLE advert capable of receiving a message for controlling a service associated with the wireless communications device after transmission of the at least one SDPT.
A computing system comprising a processor and a memory, the memory storing data and computer-executable instructions that, when executed by the processor, cause the computing system to:
- prepare an at least one sequence of data packets comprising an at least one first data packet type (FDPT) followed by an at least one second data packet type (SDPT) wherein:
- a counter is initialized prior to preparing the at least one sequence of data packets;
- the counter is incremented by one after preparing each sequential data packet;
- the information in the at least one FDPT comprises an identity of the wireless communications device, a constant time interval value, the counter value, and an indication that the at least one FDPT is a non-connectable Bluetooth Low Energy (BLE) advert;
- and
- the information in the at least one SDPT comprises an identity of the wireless communications device, the constant time interval value, the counter value, information on obtaining further data including a radio data channel and the transmit timing for an at least one further data packet, and an indication that the at least one SDPT is a non-connectable BLE advert;
- and
- transmit the at least one sequence of data packets wherein
- each successive data packet is separated by a transmission time interval from the last transmitted data packet;
- and
- the transmission time interval is the constant time interval value plus a random timing jitter that is randomly determined for each data packet.
