Grenada Police Force, Grenada

The customer

The Police in the Eastern Caribbean country of Grenada were left without communication after a natural disaster in 2004.

Situation

When Hurricane Ivan brought 220kmh winds to the island in September 2004, two-thirds of Grenada residents were left homeless. Police mobile communication was urgently required to coordinate emergency relief and enforce a dusk-to-dawn curfew to prevent looting.

Virtually all power lines were down and all communication links destroyed. Mobile & Marine (M&M) Systems, the Tait dealer in neighboring Barbados, was called on to provide temporary Police communications.

Response

Within 24 hours M&M had programmed radios, flown a staff member to Grenada who liaised with the Police, and had a temporary system in place.

A 25W Tait portable repeater was installed at the Police headquarters on a hill above the capital city. A Tait mobile was installed as a base radio at the main Grenada airport, and Police were issued with Tait portables.

Outcome

Placing the portable repeater on a high site proved effective in quickly establishing communications following the emergency.

The portable repeater operated on its built-in battery for more than 24 hours until a generator was found. Until power was restored the portable radio chargers were connected to 12V car batteries salvaged from vehicles destroyed by the hurricane.

“The Tait base station is light, robust and water resistant, and the internal batteries make it a self-contained unit. The Tait terminals also stood up well to use in a very demanding environment, and the power save function in the Tait portables maximized shift life for the batteries.”

White Paper

Under the Hood: Coverage theory for Public Safety networks - a System Engineer's view

This white paper provides network operators some insight into how a System Engineer can design for network coverage that meets specific requirements. It addresses three basic techniques, which, used individually or in combination, can overcome geographical or urbanization influences, to increase coverage reliability. While this paper is especially relevant for the critical coverage requirements of Public Safety operators, the principles described are equally applicable for other sectors.
