PL+S 2017: Riedel debuts Bolero wireless intercom system

Riedel Communications has used this year’s Prolight & Sound show to introduce Bolero, the company’s latest wireless intercom solution.

Bolero is an expandable, full-roaming, DECT-based intercom system in the license-free 1.9GHz frequency range.

Fully integrated into Riedel’s Artist digital matrix intercom platform, Bolero offers connectivity that can be applied three ways: as a wireless beltpack, as a wireless keypanel, and — in an industry first — as a walkie-talkie radio.

Bolero runs over a standards-based AES67 IP network. Decentralised antennas connect to AES67 switches and then to Artist frames equipped with AES67 client cards, providing a fully integrated point-to-point intercom ecosystem with ‘seamless’ roaming capabilities.

According to Riedel, the Bolero voice codec provides both higher speech intelligibility and more efficient use of RF spectrum supporting twice the number of beltpacks per antenna for the same audio bandwidth as other DECT-based systems. The codec has high-quality latency characteristics with efficient processing power, providing ‘excellent’ beltpack battery life, and saving DSP processing power for other functions.

Bolero also features Riedel’s ADR (Advanced DECT Receiver) technology, a diversity receiver technology specifically designed to reduce sensitivity to multipath RF reflections, making the system useable in challenging RF environments where other systems may experience difficulty.

The beltpacks support Bluetooth 4.1, allowing either a Bluetooth headset or a Smartphone to be connected. When a Smartphone is connected, the beltpack can act like a car’s "hands free" setup so the user can receive calls on their phone and talk and listen via their beltpack headset. Users can also make calls and then connect that person into the intercom matrix, eliminating the need for a telephone hybrid. Finally, in an industry first, the beltpack can be used without a headset like a walkie-talkie radio utilising an integrated mic and speaker.

"Bolero is a category-changer for wireless intercom systems," said Thomas Riedel, the company’s CEO. "A lot of time and effort has gone into every phase of Bolero’s development, a true ground-up development touching all aspects of design. We are proud to share that the BBC is already building their new studio intercom systems around the Bolero wireless concept."
