Bolero is a point-to-point, full-roaming, DECT-based intercom system in the license-free 1.9GHz frequency range. Bolero 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, Bolero can easily accommodate large areas and long distances. To the system, 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.
With the adjustable power output of Bolero antennas, users can reduce power to enable higher antenna density in a given RF space and therefore improve performance in harsh RF environments. To increase capacity, users can create “islands” of RF spaces. A Bolero beltpack is registered with a unique system ID, and each beltpack is capable of “remembering” up to 10 other system IDs. This enables beltpacks to move from island to island; e.g. studio to studio. In this manner, Bolero is able to support deployments of more than 100 beltpacks.
Bolero features Riedel’s exclusive Advanced DECT Receiver (ADR) technology, a multiple-diversity receiver technology specifically designed to improve RF robustness by reducing sensitivity to multipath RF reflections. The unique ADR receiver is able to differentiate between multipath reflections to cancel out group and phase delay, thus reducing audio drop-outs. The net result is a significant improvement in usability as well as fewer frame and bit errors, making the advanced DECT receiver ideal for use in challenging RF environments where other systems might have great difficulty.
Bolero was designed to make life as easy for the customer as possible. With other solutions, registering a beltpack to the antennas is often a complex process that requires a user to go into the beltpack menu and apply a pin code. This process can easily take two minutes per beltpack, adding a significant amount of time if the operator must configure dozens of beltpacks. Bolero incorporates Near-Field Communication (NFC) technology for both the beltpack and the active antennas, so registration is as easy as simply touching the beltpack to the antenna.
Bolero 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.
Based on Riedel’s extensive rental experience, Bolero beltpacks use a combination of premium materials, including high-impact plastics and rubber overmolds, to create a tough device with an ergonomic feel that ensures easy use and handling. The beltpacks have been drop-tested from multiple heights and at various angles to demonstrate their ruggedness. The “Gorilla Glass” sunlight-readable color display can be inverted so that it is readable in any orientation.
The Bolero beltpacks support Bluetooth 4.1, allowing a Bluetooth headset or a smartphone to be connected. When a smartphone is connected, the beltpack can act like a car’s “hands-free” mode, giving users the ability receive calls on their phones and talk and listen via the beltpack headset. Users can also make calls and then connect the called person into the intercom matrix, eliminating the need for a telephone hybrid.
Bolero beltpacks feature four primary channel buttons and two additional buttons for each of the 6 intercom channels, plus a separate “Reply” button that easily facilitates a reply to the last channel that called. Four small rubber pips on the tripod belt clip allow the beltpack to be used on a desk as a wireless keypanel. And, in an industry first, the beltpack includes an integrated mic and speaker that enables it to be used as a two-way radio without requiring a headset.
The Bolero antennas feature a high-contrast e-ink display that indicates the antenna name, number, and location as well as menus. The NFC and AES67 components are fully integrated, and connectivity is provided with three network connections and a standard four-pin power plug. Mounting options include a rear plate with numerous mounting holes, a standard mic-stand threaded socket, and an integrated spigot holder that can be used with a Manfrotto Superclamp and other systems.
