Firstly, Audiolink supplied communications solutions on set. Indeed, Audiolink has fixed MOTOTRBO networks in place at both Warner Bros Studios in Leavesden, Hertfordshire, and nearby Pinewood Studios in Iver Heath. The systems were configured to meet the exact requirements of each film, with regards to radio users, talk groups and functionality; and teams, many of whom came from overseas, were equipped with a mix of Motorola Solutions DP4400e / DP4600e digital radios and GP340 UHF radios with covert d-shaped earpieces, smartphones and dongles. Audiolink has such an extensive pool of repeaters, radios, phones and accessories that it is always able to support numerous simultaneous film productions. Audiolink also has great experience with complicated frequency planning, to ensure each film has excellent audio and coverage, whilst not suffering any interference or cross-over with other productions or film units on site. This is essential for security, availability and privacy.
