History 

Etherstack originated in Australia in 1995 as a provider of hardware-independent air interface protocol stacks (waveforms), including for MPT-1327, DMR, TETRA, NATO and APCO P25 standards. 

Etherstack is a public advocate of standards to enable interoperability and increase vendor choice in public safety and defence communications. The company has contributed since 2003 to development of the US Telecommunications Industry Association (TIA) APCO P25 standards, including sitting as chair of several of the TIA TR-8 P25 working groups.

In 2001, a software abstraction of the TETRA protocol stack developed by Etherstack was used by Racal (now part of Thales) in the development of a covert TETRA radio, designed for use by UK police and UK special forces.

In 2006, Etherstack joined with Aeroflex to develop and market products for performing conformance tests against the TIA P25 air interface protocol standards.

By 2007, Etherstack had branched out into digital RF transceiver design and established its first RF research and development group in Reading, UK. This team developed Etherstack's first small form factor SDR (software defined radio), the high performance XR-25 module which is still used in avionics and tactical communications today. The XR-25 also hosted Etherstack's first FIPS 140-2 certified cryptographic module under its Nexus Wireless brand, which included Etherstack's own implementations of a raft of AES & DES algorithms which the company separately licensed to numerous US, Canadian, European and Japanese wireless equipment manufacturers.

On March 28, 2007, Icom Incorporated of Japan announced that they had signed a long-term MOU with Etherstack to work together on digital radio projects for various professional markets around the world.

Etherstack began work with the safety and security business unit of Cisco Systems in late 2007 on the development of a range of public safety radio network infrastructure products aimed at the first responder segment of North American markets. These developments led to the formation of Etherstack's Networks engineering team in Sydney and the development of a full digital land mobile radio network product line based on the TIA APCO P25 communications standard which the company licensed to multiple other manufacturers and also produces complete turnkey systems under its own label.

In 2008, Etherstack signed a second contract with the Swedish Defence Material Administration for the continued development and support of a TETRA-based mobile station using Etherstack's TETRA SCA waveform as part of the US Swedish JTRS co-operation project.

The National Law Enforcement and Corrections Technology Center Communications Technologies Center of Excellence announced in January 2009 that it would launch a pilot of the APCO P25 radio network in Cape May County, New Jersey, that would integrating Etherstack's Land Mobile Radio network controller software.

In 2010, Etherstack participated with Motorola and four other manufacturers in the first interoperability testing of the TIA's Project 25 ISSI (Inter RF Sub System Interface) demonstrating multi-vendor interworking capability across different manufacturers networks that conform to the TIA APCO P25 standard. This activity would lay the basis for Etherstack's future 3GPP standards compliant IWF (InterWorking Function) product for MCPTX solutions.

In March 2011, Etherstack and Alcatel-Lucent demonstrated a world first of integration of a native P25 PTT call over an LTE cellular network through to a traditional narrowband P25 network using the ISSI standard at the Bell Labs facility in New Jersey.

Etherstack plc (UK) is a holding company that has been incorporated since 2006. The company is majority Australian owned, Australian controlled and Etherstack plc is listed on the Australian Securities Exchange (ASX). The company operates research and development offices in New York, London, Yokohama, and Sydney.

Technology Licensing for Critical Communications 
Etherstack researches, develops and licenses the underlying technologies for SCA Software-defined radio (SDR) waveforms, Land Mobile Radio (LMR) protocol stacks, SDR RF transceivers, test platforms, and encryption modules and solutions for narrowband and broadband solutions for the LMR and defence communications industries.

The defence and waveforms division of Etherstack specialises in standards based and bespoke waveform technologies. In May 2022, the company announced the first implementation of the NATO NBWF (narrowband waveform) which is proposed to enhance communications interoperability between NATO forces in the future.

The company manufactures is own specialised highly secure wireless network and communications devices for use in large scale fixed radio networks as used by public safety, electric utilities, border protection and resource sectors as well as a family of tactical communications devices for remote deployment of ad hoc networks around the world, including secure PTT (push-to-talk) over satellite solutions.

Fixed and Deployable Secure Wireless Voice and Data Systems 
Etherstack has deployed and supports numerous large scale digital P25 networks in Canada, Australia and the United States, spanning vast geographic areas including Alberta & Iqaluit in Canada, Idaho, New Jersey, Pennsylvania and Maryland in the United States and one of the largest digital radio networks in the world in Queensland, Australia.

Etherstack's SFFR-6 Tactical Repeater product (aka "Go Box") was evaluated in June 2022 by the US Department of Homeland Security and given the highest score in comparison to the other tactical repeaters under evaluation.

In early 2023, Etherstack deployed it's P25 over Satellite IVX (In-Vehicle Switch) product for use by The Royal Bahamas Defence Force in vehicles and maritime vessels.

Multi-Vendor, Multi-Domain Interworking for Emergency Services 
For the emerging 3GPP MCX (mission critical push-to-talk/video/data services over LTE) space, Etherstack has developed a 3GPP compliant InterWorking Function (IWF) to bridge P25, TETRA and DMR radio networks currently used by public safety agencies to cellular MCX services over LTE. In 2022, AT&T announced that Etherstack was the supplier of its 3GPP LMR-IWF network element for its nationwide United States FirstNet system for first responders. Etherstack's 3GPP LMR-IWF is being supplied to AT&T by Samsung under Etherstack's global teaming agreement with Samsung for Etherstack's 3GPP LMR-IWF product.

Etherstack also licences standards-based P25 ISSI, P25 CSSI and P25 air interface protocol stacks to radio system, control room and terminal vendors to enable them to expose open standards-based interfaces for interoperability with third-party vendors and for end-to-end integration of mission critical voice and data across multiple domains and vendors.
