High data low latency communications with minimized power consumption
First Claim
1. An endpoint device capable of communicating with a data collection device, the endpoint device comprising:
- a first communication subsystem configured for low data rate messaging;
a second communication subsystem configured for high data rate messaging; and
a controller in communication with the first and second communication subsystems,wherein the first communication subsystem is to be used as a primary means of communications with the data collection device, and the second communication subsystem is to be used as needed for high data rate communications with the data collection device; and
wherein the controller is to turn on the second communication subsystem in response to receiving a wake-up command from the data collection device via the first communication subsystem when the wake-up command includes a request for data that requires transmission at a high data rate.

Abstract
An endpoint device capable of communicating with a data collection device comprises a first communication subsystem for low data rate messaging, a second communication subsystem for high data rate messaging, and a controller in communication with the first and second communication subsystems, where the first communication subsystem may be used as a primary means of communications with the data collection device, and the second communication subsystem may be used as needed for high data rate communications with the data collection device. The controller may turn on the second communication subsystem for scheduled or unscheduled transfer of data at a high data rate, in response to receiving a wake-up command from the data collection device, in response to receiving an alarm event at the endpoint device, etc. A wake-up command may include a request for data between scheduled data transfers, a parameter change request, etc. Various methodologies are also disclosed.

9. A method of communication between an endpoint device and a data collection device over a network, the method comprising, at the endpoint device:
-
waiting for a wake-up command from the data collection device by a receiver of a first communication subsystem of the endpoint device, the first communication subsystem configured for low data rate communications; and upon receiving the wake-up command, wherein the command includes a request for data that requires transmission at a high data rate; turning on a second communication subsystem configured for high data rate communications; and transmitting the requested data to the data collection device at the high data rate via the second communication subsystem. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory computer-readable medium having computer program logic stored thereon, the computer program logic including instructions to cause a controller of an endpoint device to:
-
wait for a wake-up command from a data collection device, by a receiver of a first communication subsystem configured for low data rate communications; and upon receiving the wake-up command, wherein the command includes a request for data that requires transmission at a high data rate; turn on a second communication subsystem configured for high data rate communications; and transmit the requested data to the data collection device at the high data rate via the second communication subsystem. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
