Wireless tech hits new levels of stability and scalability

Published on January 4th, 2021

LumenRadio, a global provider in reliable wireless communication, has released version 2.5 of Mira which introduces stability improvements for larger, and more stable networks. With the new version, LumenRadio says it can push the limits of stability and scalability even further.

Johannes Arvidsson, product owner at LumenRadio explains Mira 2.5, “We’ve gone back to the drawing board on implementations which are part of the very core of the network stack. By optimising radio timing, clock synchronisation and routing layers we take Mira to new levels of stability and reliability. Doing this while also not impacting current consumption, keeping it to our world record levels, is an achievement that we’re very proud of.”

“Our customers are constantly working on scaling up their wireless solutions to cover greater areas and more devices, a trend that is consistent with what is happening in the IoT space in general,” Johannes continues. “It is only natural that Mira follows this development, now and in the future.”

Also coming in this release are two ‘quality of life’ features:

Snappier BLE beacons

To achieve a fast response between devices and phone applications, a very low BLE beacon interval may be necessary. Due to constraints in the concurrent time slicing between Mira and BLE beacons, previous versions of Mira were limited to only sending 5 beacons per second. Mira now supports double that amount, 10 advertisements per second, enabling even more responsive commissioning and maintenance, for a better user experience.

Easier network restarts

Mira version 2.5 introduces a feature to make scheduled network restarts less intrusive on running applications. Previously, the best practice in order to achieve short restart/rebuild times was to fully reboot all nodes in a network simultaneously whenever a network restart was necessary. This can be a problem for any device running critical applications which needs to be kept running. This is where the rejoin function comes in.

It enables only the root node being forced to reboot in the same scenario. All other nodes can use the rejoin function instead of rebooting the entire chipset, all while still achieving a short restart/rebuild time. Mira version 2.5 also reintroduces support for the MKW41z chipset, enabling us to deliver the best Mira ever across all our platforms.

With these changes Mira strengthens its position as the most resilient and robust wireless IoT solution. Going forward we will keep our commitment to continuously improve in that area, but also turn our sights to the monitoring and management of Mira networks.
