Hollyland launches large-scale wireless intercom system

Designed for broadcast, live events and industrial applications, Hollyland has released the Solidcom H1 bundle comprising the Geo Central Station, Solidcom ANT01and Solidcom BPK01. At the centre of the system is the Geo Central Station, a flexible hub that supports up to 80 wireless beltpacks when used with an antenna, all without any licensing fees. Leveraging roaming cascade technology, the system extends wireless coverage to over 4 million m², equivalent to approximately 560 soccer fields. Equipped with native Dante integration and 4x4 network ports, the Geo Central Station eliminates the need for additional audio interfaces, reducing rack space and installation complexity while maintaining reliable, independent audio channels for every group.

The Solidcom H1 system offers flexible deployment options, functioning as either a standalone system or integrated with the Geo Central Station. It supports up to 30 beltpacks in standalone mode, which can be expanded to 80 beltpacks when linked with the Geo Central Station. Built for productions of any scale, it has been designed to provide uninterrupted connectivity and dynamic deployment across diverse shooting or operational environments.

According to Dave Liu, CTO of Hollyland’s R&D management centre, the modular topology allows scalable user capacity based on project needs. Beltpacks can seamlessly roam across remote radio units (RRUs) and central stations, offering location-independent deployment in challenging environments. With built-in cloud call capabilities, the system enables real-time communication across wide-area networks.

The 30–80 beltpack expansion capability is said to support everything from small sets to major live productions, all on the robust 1.9GHz frequency band. A single Solidcom ANT01 unit provides a 500m radius of coverage in open-field conditions. When cascaded, the system creates a seamless large-scale wireless network spanning an extensive area.

To meet the demands of multi-team coordination, smart group management also enables operators to save, assign and switch between up to 100 preset communication groups, ideal for multi-team collaboration in fast-paced environments. Even in smaller setups, the system supports up to 12 independent groups per cluster of ANT01 units.

In addition, the Solidcom BPK01 beltpack is built for mobility, weighing less than 305g including battery and offers up to 15 hours of operation. Integrated Bluetooth support allows users to pair wireless earbuds or headsets for a fully cable-free experience. Its four programmable buttons can be customised for advanced control, including multichannel talkback, call alerts and combination actions, all within a simplified user interface.

Adding to its adaptability, cloud access is fully integrated. Two Geo Central Stations linked across sites can manage up to 80 beltpacks, while three Solidcom ANT01 units linked in the cloud can handle up to 30, allowing flexible participation from off-site coordinators, remote directors or technical leads. In addition, the system enables real-time remote diagnostics and support. Authorised users can access system settings and configuration interfaces via a secure web browser, providing technical assistance and maintenance without the need for onsite intervention.
