Riedel Introduces Bolero Point-To-Point Intercom System

Riedel Introduces Bolero Point-To-Point Intercom System

Bolero is a point-to-point, full-roaming, DECT-based intercom system in the license-free 1.9GHz frequency range that runs over a standards-based AES67 IP network.

Bolero is a point-to-point, full-roaming, DECT-based intercom system in the license-free 1.9GHz frequency range that runs over a standards-based AES67 IP network. Decentralized antennas connect to AES67 switches and then to Riedel's Artist digital matrix intercom frames equipped with AES67 client cards, creating a fully integrated point-to-point intercom ecosystem with seamless roaming capabilities. By using multiple AES67 switch cascades, the system can accommodate large areas and long distances. The beltpacks look just like Riedel Artist panels but are wireless, providing the highest levels of interoperability, programmability, flexibility, and user mobility. A reprogrammable FPGA future-proofs Bolero antennas by permitting upgrades for future networks.

Bolero uses a high-clarity 7KHz voice codec to provide both higher speech intelligibility and more efficient use of RF spectrum. The codec has excellent latency characteristics providing lip sync free communications, while offering excellent processing efficiency, providing outstanding beltpack battery life, and saving DSP processing power for other functions. The codec produces exceptional audio clarity scores across multiple languages as measured on the PESQ scale. The PESQ score was developed to assess human voice quality, using true voice samples, in telecommunications. As a result of its highly economical RF bandwidth management, Bolero operates at twice the spectrum efficiency of other DECT-based systems. That equates to up to a category-redefining ten beltpacks per antenna (fully roaming) and up to 100 antennas per system. The system features Near-Field Communication (NFC) technology for both the beltpack and the active antennas, so registration is done by touching the beltpack to the antenna. Advanced DECT Receiver (ADR) technology in included, reducing sensitivity to multipath RF reflections.

This is the only wireless intercom system with redundant power capabilities. In a Power-over-Ethernet (PoE) scenario, an AES67 switch with PoE can power multiple antennas over CAT-5 up to 100 meters from the switch. In an external DC power scheme, small power supplies at each antenna can provide primary power or act as backup to the PoE. The beltpacks feature four primary channel buttons and two additional buttons for each of the six intercom channels, plus a separate "reply" button. Four small rubber pips on the tripod belt clip allow the beltpack to be used on a desk as a wireless keypanel. The beltpack includes an integrated mic and speaker that enables it to be used as a two-way radio without requiring a headset. The system also supports Bluetooth 4.1 for use with a compatible headset or smartphone.
