5G for Defence and Autonomous Military Solutions

Integrated Modular Unmanned Ground Systems (iMUGS) consortium is a 13-party collaboration focused on standardising a European-wide ecosystem for aerial and ground platforms, command, control and communication equipment, sensors, payloads, and algorithms. The parties involved in the iMUGS project are Milrem Robotics, Latvijas Mobilais Telefons (LMT), Talgen Cybersecurity, Safran Electronics & Defense, NEXTER Systems, Krauss-Maffei Wegmann, Diehl Defence, Bittium, Insta DefSec, sol.one, dotOcean, GMV Aerospace and Defence, and Royal Military Academy of Belgium.

Within the iMUGS project, the Latvian MNO LMT is conducting a study on the potential use of 5G in autonomous military solutions. Back in September, the future role of 5G in autonomous military solutions was demonstrated by LMT in collaboration with the iMUGS Consortium. 

A press release said:

The demonstration, during which various scenarios were played out in battlefield-like conditions while showcasing specific use cases, took place today, on September 23rd, at the Ādaži military base in Latvia.

This was the second of a total of six demonstrations with the aim of showcasing the results of the iMUGS (Integrated Modular Unmanned Ground System) project – one of Europe’s leading defence industry development projects. The demonstration was organised by LMT, one of the members of the iMUGS consortium, with the support of the Latvian National Armed Forces and the project coordinator Milrem Robotics.

During the demonstration, the troops played out close-to-reality military scenarios in operational environments and relevant climatic conditions. Milrem Robotics’ unmanned ground vehicle THeMIS, was used, along with a number of other cutting-edge military technologies, such as:

  • LMT’s battle Information Management System for displaying the data of the payloads and as a command system for scenario execution
  • LMT’s Intelligence Surveillance Reconnaissance (IRS) system for performing aggressive fire detection and source recognition
  • The ISR system ‘Skudra’ for performing the signal intelligence mission
  • A highly protected wheeled vehicle DINGO 2 as a command post from which the mission was led

Alternative communication networks were used by the troop and an unmanned ground vehicle, in scenarios that included switching from a tactical network, provided by Bittium in collaboration with LMT, to 4G and 5G networks.

Some videos shared by LMT are embedded below:

At the 5G Techritory 2021, Armands Meirāns, Innovation Leader for Defence & Public Safety at LMT gave a presentation on 5G for Defense, as showcased by iMUGS Consortium. His talk is embedded below:

KMW's C-band 64TRx 640W 25kg Massive MIMO


There is a Massive MIMO weight wars taking place. Last month, Ericsson announced that it had a 64T64R Massive MIMO antenna radio unit that weighs just 20kg. Two days later, Huawei announced at MWC Shanghai that its latest equivalent tips the scales at only 19kg. The Mobile Network covered it nicely here and so did Light Reading here.

While Huawei & Ericsson are number 1 and 2 players in the world, at a far smaller scale is KMW (Korea Micro Wave). In conjunction with RCR Wireless, they announced a C-band 64TRx 640W 25kg mMIMO Hardware Ready along with a whitepaper and a video. 

The whitepaper can be downloaded from here and the summary says:

Massive MIMO technology has been deployed for capacity improvement as the 5G NR system. However, in the aspect of coverage expansion, there has been no satisfactory solution so far.

KMW applies the Modular Architecture technology to develop the mMIMO RU (64TRx, 640W, 25kg) with the natural convection cooling system as a solution of 5G coverage expansion.

This Modular Architecture, AFAM (Antenna, Filter and Power Amplifier Module), introduces Radio’s heat source separation that maximizes heat dissipation performance and minimizes the size and weight. And it allows operators to provide the desired smartest service at a lower investment.

Modular RU can also be a standardized platform with easy frequency variation just in time. Moreover, if the market requests O-RAN RU, the product shall be provided on time with the set of HW/SW.

KMW is a professional RU H/W company delivering 5G mMIMO RU to Global Market collaboration through S/W JDM with Global OEM. KMW is ready to cooperate with the global partners and customers.

It would be nice to see some of these massive MIMO units deployed in Open RAN networks later this year. 

Last year Vodafone had announced a bevy or Open RAN radio vendors. Hopefully we will see some more massive MIMO units from others. 

Finally, it should be noted that KMW also goes by the name GigaTera, which is what was earlier known in the US as KMW Inc. Details here.
