The Solution
Audiolink deployed a two-way radio system from Motorola Solutions, comprising circa 350 GP340 VHF portable radios, a DM3600 mobile two-way radio set up as a dispatch unit in the Assistant Director’s trailer and a wide range of accessories, including waterproof cases, covert kits, D-shaped earpieces and covert acoustic tube earpieces. Due to the wide radio coverage needed, Audiolink also installed a MOTOTRBO™ DR 3000 Repeater to extend range to 4–5 square miles along the beaches and across the open sea on location at Dunkirk and Urk (the Netherlands), where action shots were being filmed. Audiolink went on-site at Dunkirk to ensure the repeater was correctly installed and the full system working optimally; due to ease of installation, Warner Bros. was able to set up the repeater in Urk without further external assistance.
There was no need to install a Repeater on location at Weymouth, as filming was confined to a smaller area. However, Audiolink did also supply a large number of iPhone 6s to the American team whilst they were on location in the UK.
Audiolink also spoke to the various authorities in France, the Netherlands and the UK to get the radio frequencies cleared for use in each country, so Warner Bros. could keep the same radios for the duration of filming. Audiolink provided technical support and spare radios and accessories to Warner Bros., in case of damages or loss overboard during sea scenes.
