- Etherstack plc stands as a global innovator in wireless communications, dedicating its expertise to mission-critical radio technologies for equipment producers and network providers across Australia and internationally. The company's advanced solutions facilitate push-to-talk (PTT) functionalities over sophisticated digital land mobile radio (LMR), cellular, and satellite communication systems. Their extensive portfolio includes a variety of encryption offerings, such as the P25 Security Suite, which integrates AES/DES P25 encryption engines with P25 key fill device (KFD) compatibility for full P25 subscriber security. This suite also encompasses P25 key management facilities, P25 security dongles, and FIPS 140-2 Cryptographic Modules, single-board devices that deliver APCO P25 encryption, decryption, and secure key management in line with FIPS140-2 standards. Etherstack further provides specialized defense waveforms, offering technology licensing and transfer, alongside expert services, waveform heritage, and robust testing and development environments for mitigating risks through reconfigurable and framework architectures. The company delivers core LMR network components, supporting wireless communications protocol stacks like APCO P25, dPMR, DMR, MPT1327, and TETRA. Additionally, it offers tactical and satellite solutions, featuring P25 tactical repeaters (known as "Go Box" devices) and IVX – PTT IP radio for versatile deployments. Etherstack's technology connects diverse radio networks with modern 4G/5G cellular systems through its LTE Interworking Function (LMR-IWF). Their client base spans public safety, defense, utilities, transportation, and resource industries. Recent achievements include being selected by AT&T as a 3GPP compliant MCX IWF supplier and securing a significant £14.2 million contract with the UK Home Office for its Emergency Services Network (ESN) in November 2025. The company, initially incorporated as MM&S (5698) plc, adopted the name Etherstack plc in May 2012 and operates from its base in Chippendale, Australia.
