ASX Announcement

ETHERSTACK PLC

[ASX:ESK]

("Etherstack" or the "Company")

ETHERSTACK AND CML COLLABORATE ON DMR TIER 2 AND TIER 3

Etherstack plc is pleased to confirm it will offer its DMR Tier 2 and Tier 3 Protocol Stack software integrated to existing DMR products from mixed-signal semiconductor company, CML Microcircuits.

By collaborating with CML, Etherstack hopes to lower the barrier to building high quality, low cost DMR radio equipment. Both companies are longstanding, experienced suppliers of Land Mobile Radio (LMR) technology and together offer a highly qualified DMR engineering team for ongoing support, advice and feature development.

The DMR segment of the market is the fastest growing of the US$18B global LMR industry according to IHS research.

Etherstack’s flexible licensing models will ensure customers have full ownership and control over the software and functionality of their radio equipment.

“This is a great chance to offer customers a unified software and hardware option for DMR that keeps product development firmly in the hands of the customer” says Anna Squires, Head of Etherstack’s Protocols Division. “DMR is a modern, flexible and truly international standard. We hope this offering will contribute to the strong growth of DMR radio technology around the world.”

At the Critical Communications World (CCW) 2016 tradeshow in Amsterdam last month, Etherstack demonstrated its DMR Tier 3 stack running on prototype hardware using CML’s DMR silicon making calls to a third party DMR Tier 3 handset via DMR infrastructure. A fully integrated solution is under development between the companies.

“A comprehensive DMR silicon plus software solution; that is a unique DMR market enabler” says Malcolm Lyman, Marketing Manager of CML Microcircuits UK. “This solution will allow new manufacturers to enter the DMR market quickly with low risk and facilitate existing manufacturers to implement DMR Tier 3 quickly.”
