How to ensure that the sensors run on batteries for more than 10 years, while providing measured values every minute? Find out more in the interview.

Interview with Hynek Syrovatka from IQRF Alliance and Ivona Spurna.

A nice day to all listeners, today I would like to welcome Hynek Syrovatka, who is, among other things, the technical director of the IQRF Alliance.
Hello.

Hynek, IQRF technology has got further improvements in recent months. Those who are interested have probably heard of beaming, local FRC, and so on. Can you explain these functions, so that even people who have not heard of IQRF yet understand what they are for, what practical applications they are suitable for?

FRC^® stands for Fast Response Command and it is the fastest network control, management and data collection across wireless networks.

A patented method how to send a command from the Coordinator to all or selected Nodes and receive responses including small data collected by individual Nodes in outstandingly short time.

FRC is much faster (even by orders of magnitude) than polling individual Nodes one by one:

See chapter FRC in IQMESH Network deployment technical guide.

Typical usage

Control

Fast sending a command to multiple Nodes and checking the results (e.g. an acknowledged broadcast).

Telemetry

Fast collecting of small data from multiple Nodes.

Offline FRC is intended for Beaming sensors. It operates identically as common FRC but skips the individual phase within the FRC response.

Beaming

A Beaming sensor is a Node device working in Offline mode (see just below), and communicating unidirectionally and asynchronously with Aggregating repeaters only.

An Aggregating repeater is a repeater providing not only a common routing but additionally concurrently serves as an interface to collect and forward data from Beaming sensors.

A Beaming sensor, once bonded, works in Offline mode. It is sleeping all the time and periodically or on some event asynchronously sends data to all Aggregating repeaters which are in direct RF range. Aggregating repeaters always store the last received data from every repeater into the log memory and automatically clear it after reading out. The data can be read out synchronously by the Coordinator using the Offline FRC. The Offline FRC is an analogy to the common FRC intended to read out common (non-Beaming) sensors. The data incoming to the Coordinator has the same format as from common (non-Beaming) sensors.

Local sensors work at the same RF channel as the entire IQMESH network which may cause unwanted interference. In some cases, an LBT (Listen Before Talk) check performed before the asynchronous packet is sent may help.

The Beaming sensors communicate unidirectionally and no confirmation is provided.

Local FRC is an FRC asynchronously launched from a Node to control other Nodes in direct range. Quickly, without lengthy propagation of the packet through the entire network. Thus, e.g., controllers (pushbuttons, switches, motion sensors, …) can control and monitor actuators (lights, blinds, …) with no significant delay.

Are you interested in making your lights smart? You can now do it quickly thanks to the IQRF DALI Bridge.

MICRORISC s.r.o. introduces the IQRF DALI Bridge device for connecting your DALI lights to the IQRF wireless mesh network.

You can plug the IQRF DALI Bridge into your light with the DALI interface. Send DALI commands to control the lights (switching off, switching on, changing the intensity of lighting, etc.) via the IQRF wireless network. The IQRF is capable of connecting up to 239 lights into one network which can be then remotely controlled and monitored.

Using the IQRF to communicate with the lights enables you to use it as a backbone network for other devices such as AC units, heating, air quality etc.

Check www.wireless4lights.com where you can learn more about robust wireless connectivity for DALI devices and how to make obsolete light a smart light.

Use the IQRF DALI bridge, which you simply plug into your light with the DALI interface.

Light control commands – switching off, switching on, changing the intensity of lighting, etc. – are then sent over the IQRF wireless network. This device allows communication with a DALI-enabled device over the IQRF wireless Mesh network.

Connecting to your light-supporting DALI standard is simple and requires no special and expensive development.
