Estonian startup Wayren’s technology was successfully tested during HIMARS live-fire exercise

At the first live-fire exercise of HIMARS rocket launchers conducted by Estonian Defence Forces on Saaremaa, the critical communication technology developed by Estonian defence industry startup Wayren was successfully tested. This technology ensures vital communication between units even when traditional communication systems are no longer operational. Wayren participated in the NATO DIANA Estonian Accelerator.

Reservists participating during the exercise of the division’s artillery battalion’s rocket artillery battery used Wayren’s Singularity software, which enabled them to share location information and functioned as an additional communication mechanism for organizing logistics. Thanks to the light and scalable nature of Wayren’s technology, its use was expanded during the exercise to also provide location sharing for intelligence and weapons-level data transmission.

Wayren’s CEO and co-founder Henry Härm stated that the live-fire exercise simulated a highly realistic situation where, due to complex terrain and dynamic condition, conventional communication solutions fail – “The results showcased that our technology is reliable and simple to use. The Singularity software kept the units operational even under extremely difficult conditions,” said Härm.

Wayren’s CSO and co-founder Tarmo Aia noted that the exercise demonstrated the necessity of their solution for defence forces, for whom reliable communication is vital for success in their primary tasks. “We are proud that our efforts in developing lightweight hybrid mesh network technologies have borne fruit. This gives us confidence to continue investing in this field,” Aia added.

The exercise held on the Undva Peninsula in Saaremaa took place from the 4th to the 12th of July and aimed to improve the unit’s combat readiness, develop interoperability, and reinforce soldiers’ knowledge and skills in using weapons systems. The M142 HIMARS artillery rocket launchers are considered one of the most modern long-range indirect fire systems in the world. Their introduction into the Estonian Defence Forces marks a significant increase in national defence firepower in both strength and range.

Wayren is a startup founded five years ago by three former cyber defence personnel members — Henry Härm, Oliver Tiit, and Tarmo Aia. This spring, Wayren signed a strategic investment agreement worth 7.9 million euros.

The Singularity communication platform developed by Wayren enables reliable communication on the battlefield between soldiers, command staff, and various platforms under challenging conditions. The company’s patent pending system creates a robust hybrid mesh network connecting units, vehicles, or command posts, synchronizing data in parallel through various civilian and military communication technologies. Currently, the system has been delivered as a pilot project to the Estonian Defence League and is actively tested by the Estonian Defence Forces and in Ukraine.

Wayren recently successfully completed the NATO Diana accelerator, being one of only two Estonian companies selected for this year’s group.
