Mobile Tornado helps international efforts to address the crisis

The Harrogate-based firm said its PTT (push to talk) system is being rapidly deployed to meet communications needs in national emergency situations.

Chairman Jeremy Fenn said: "During a nationwide emergency most countries need to mobilise their emergency services which include the police, emergency medical services, and in many cases, volunteer organisations that provide support to the public.

"The biggest problem during these situations is coordination and a reliable communication system. Unfortunately, most countries have a limited communication system that is usually used by just one of these groups and coordination becomes the biggest issue.

"The rapid deployment of a nationwide communication system based on traditional LMR is almost impossible as it takes months and sometimes years to deploy.

"Mobile Tornado delivers the perfect communication solutions during these emergencies across the cellular system provided by the Mobile Network Operators."

The group said the Covid-19 pandemic has clearly created unprecedented challenges for businesses around the world.

Mr Fenn said: "Our absolute priority has been to ensure the wellbeing of our people, and accordingly we are following the UK, Israel and Indian governments' advice, with our teams now predominantly working from home."

He made the comments as the firm announced a 16 per cent increase in revenue to £4.5m in 2019. Gross profit rose 19 per cent to £3.2m.
