Telemetry use cases

Telemetry is the automated sensing, measurement of data, and control of remote devices. The emphasis is on the transmission of data from devices to a central control point. Telemetry also includes sending configuration and control information to devices.

MQ Telemetry connects small devices by using the MQTT protocol, and connects the devices to other applications by using IBM MQ . MQ Telemetry bridges a gap between devices and the internet making it easier to build "smart solutions". Smart solutions unlock the wealth of information available on the internet, and in enterprise applications, for applications that monitor and control devices.

The following diagrams demonstrate some typical uses of MQ Telemetry:

Telemetry: Smart Electricity
	MQTT message containing energy usage data sent to service provider. MQ Telemetry sends CONTROL COMMANDS based on analysis of energy usage data. For more information, see the following use case: Telemetry use case: Home energy monitoring and control

Telemetry: Smart Health Services
MQ Telemetry sends Health Data to your Hospital & Doctor. MQTT message alerts or feedback can be sent based on analysis of Health Data. For more information, see the following use case: Telemetry use case: Home patient monitoring

Telemetry: One in a Crowd
	A simple card transaction is sent to the bank's server. MQ Telemetry identifies the one person from the thousands, alerting the customer that their card has been used. MQ Telemetry can use the simplest input of information, and locate that individual.

The use cases described in the subtopics are drawn from actual examples. They illustrate some ways of using telemetry, and some of the common problems that telemetry technology must resolve.

• Telemetry use case: Home patient monitoring
  In the collaboration between IBM and a healthcare provider on a cardiac patient care system, an implanted cardioverter defibrillator communicates with a hospital. Data about the patient and the implanted device are transferred using RF telemetry to the MQTT device in the home of a patient.
• Telemetry use case: Home energy monitoring and control
  Smart meters are often coupled with a local telemetry network to monitor and control individual appliances in a home. Some are also connected remotely for monitoring and control at a distance.
• Telemetry use cases: Radio Frequency Identification (RFID)
  RFID is used in many applications, and the types of use cases vary enormously. RFID use cases, and home patient monitoring and home energy monitoring and control use cases, have some similarities and differences.
• Telemetry use cases: Environment sensing
  Environment sensing uses telemetry to collect information about river water levels and quality, atmospheric pollutants, and other environmental data.
• Telemetry use cases: Mobile applications
  Mobile applications are applications that run on wireless devices. The devices are either generic application platforms or custom devices.
