Workshop 1 | The TAK Imperative: Why Australian Mission Operations will Embrace this Unifying Common Operating Picture
Thursday 24 July |9.00 AM – 12.30 PM
Presented by: Graham Tait | Mesh Solutions Lead, Hypha, and Scott Geldard | COO, Hypha and Matt Franks | Senior Solutions Engineer, Hypha
As we explore TAK (Team Awareness Kit) to understand what it is, its opportunity for application and explore various use cases, this workshop will be an opportunity to hear from the experts and experience some hands-on training with TAK.
TAK delivers an interoperable unified common operating picture (COP) based on non-proprietary, open-source software developed and continuously updated by the US Department of Defence.
Australian public safety agencies and emergency management organisations can embrace the civilian TAK stream as a unified operational picture, that fits in the hands of remote emergency workers and is also available to benefit private-sector users too, including park operations, marathon and festival organisers and other large events and operations.
Hear how this life saving approach to technology use can serve Australia:
- Hear about strategies for deploying TAK on an enterprise scale, from device selection to end user training and adoption
- Observe in-depth case studies on the use of TAK for special events, law enforcement tactical operations, wildland firefighting, and search and rescue
- Learn about the large range of communications options for using TAK in remote/off-the-grid conditions
- Discuss the inclusion of TAK in interoperable communications planning, as a compliment to P25 radio, and as a scalable alternative to proprietary silos.

How Public Safety Agencies Optimised Critical Comms During the Paris Olympics
Presented by: Brad Welch | General Manager, TPL Systems
Public Safety agencies and other organisations that rely on critical communications for their emergency and day to day operations are embracing hybrid solutions in order to strengthen communications resilience. As Public Safety dedicated broadband solutions are being implemented around the world, MCPTT is becoming a large part of the hybrid solution, in conjunction with traditional Land Mobile Radio as the backbone of their communications architecture.
Although radio manufacturers are combining these technologies in their radio hardware, there are still alot of legacy radios only working on traditional radio platforms, so users are forced to use multiple devices to take advantage of radio and MCPTT platforms. This is the exact scenario that was faced by the French Police and Gendarmerie leading into the 2024 Paris Olympics, with both TETRA radios and a mobile phone based MCPTT app forming the hybrid communications platform for over 28,000 officers.
Although the addition of the MCPTT app added a more robust communications solution, it added user complexity too, as officers had to use and carry multiple accessories for voice communications. In this presentation we investigate how this issue was overcome to provide secure and seamless communication across various public safety units.

Navigating Australia’s Airwaves – Exploring Spectrum Opportunities
Presented by: Andrew May | Executive Manager, Spectrum Engineering
A wide-angle view of ACMA’s ongoing work program, including consideration of wider channels in the microwave point to point bands, the potential partial redeployment of the ‘upper’ 6.7 GHz band to wireless broadband services, and the lay-of-the-land now that ACMA have completed the multi-year “Area Wide Licence” process in the 3.4-4 GHz band across the entire continent.

Pathways to Deploy 3GPP Mission Critical Broadband Services (MCX), with Icon Water (ACT) Case Study “Move from Narrowband to Broadband”
Presented by: Rhys Clare | National Sales Manager ANZ of Airbus and Director, Australasian Critical Communications Forum (ACCF), Regional Chapter of TCCA
The presentation provides an introduction and overview of current 3GPP releases of mission critical broadband, along with the current 3GPP work schedule that includes 5G D2D Sidelink, Massive MC Video and IWF between LMR and Broadband systems. It will also include an overview of MCX interoperability testing (ETSI Plugtests) and certification. As an example of moving from narrowband technologies to critical broadband, the presentation will provide an Australian case study from an Icon Water (ACT) project entitled, “The Move from Narrowband to Broadband” that provides Icon Water with efficient and enhanced operational communication, improved safety and emergency response, whilst supporting media rich applications.

Panel Discussion: The Use of Satellite Communications in the Critical Communications Environment – Separating Fact from Fiction
Moderated by: Chris Stevens
Panellists: Luke Marchant, Hamish Duff, Scott Geldard and David Deacon
In recent years we have begun to see the use of satellite communications in critical communications environments like never before. Whilst we know and understand that technology, coverage and access has changed considerably in the last few years alone, and whilst some organisations have jumped in with both feet to adopt it’s use as part of an overall communications ecosystem, others have been slower to adopt the technology.
In this panel session we will look to separate fact from fiction with regard to its application and use; consider the threats and opportunities within the traditional LMR environment and we will also explore the barriers to entry that prevent some from making a move towards the adoption of the currently available solutions.
