Wireless Microphone Systems

Here is how this works in practice. Our team sources and sets up wireless microphone systems for shoots across Belgrade and the wider region, working from a rental inventory that has grown with Serbia's expanding film-services industry. We hold digital and analogue transmitter and receiver pairs. A range of lavalier capsules suited to different concealment and tonal needs, plus antenna distribution and RF cabling to extend trusted coverage across large sets. Each wireless package is prepped, range-checked and frequency-coordinated before delivery.

Here is the short of it. For a large-cast drama at PFI Studios near Simanovci needing dozens of channels. We plan the range as a single set up map, scanning the location and allocating clean frequencies that avoid trouble between radio mics. IEMs and any wireless video on the unit. We stage backup transmitters and receivers so a failed channel is swapped between setups. Where a production needs more channels or specific frequency blocks than Belgrade inventory holds. We supplement from suppliers across the wider Balkan region, keeping each unit within the bands ready for production work in Serbia.

Here is the breakdown. RF range in Serbia is covered by RATEL. The Regulatory Agency for Electronic Communications and Postal Services. All wireless microphone planning we carry out respects its allocations. The RF environment differs sharply across Serbian locations. Central Belgrade, where the Sava meets the Danube around the Kalemegdan fortress, is a congested range environment with broadcast and mobile traffic competing for the air, so a careful scan is key before allocating channels in the old town or Skadarlija.

Here is what that looks like on the ground. By contrast, the mountains of Tara, Zlatibor and Kopaonik and the Djerdap gorge give cleaner range and easier planning. Serbia's 25 to 30 per cent cash rebates, run through the Film in Serbia programme of the Serbia Film Commission, makes hiring local wireless inventory and RF technicians cost-good. As Serbia is not an EU member, wireless kit imported from abroad moves under an ATA carnet for short-term import, while renting locally keeps a production within RATEL's framework without that forms.
