Welcome to EWS
EWS' flagship product, the GFW-01, is set to revolutionise the way in which warning messages are disseminated to the public during emergency events, and in turn substantially improve public and road safety.
Unlike high-powered radio jammers, the GFW-01 uses sophisticated microprocessor technology that allows it to accurately control power output (transmission distance) per frequency and the pattern of transmission thus enabling accurate and localised short range coverage. This limits messaging penetration only to those in most need.
The GFW-01 transmits only on bands in use in the area, and has the ability to include and reject any radio station within the FM band. This eliminates the potential for unwanted lateral interference with other frequency users.
Not restricted to emergency service vehicles, the GFW-01 is also ideal for Road Traffic Authorities (for traffic incidents and accidents on highways or freeways), train level crossings and public warnings for natural disasters (bushfires, floods, tsunami events) and catastrophic events (major crime scenes eg. terrorist attack).
