Clear-Com FreeSpeak Cell: Cellular-Based Wireless Intercom Uses LTE and 5G to Break Through the Coverage and Spectrum Limits of Traditional Production Comms

Traditional wireless intercom systems — whether DECT, UHF, or Wi-Fi-based — all share a fundamental constraint: they rely on locally managed radio spectrum that is increasingly congested in large venues and complex live event environments. Clear-Com, the communications specialist widely deployed in broadcast, live events, and theater, has launched FreeSpeak Cell at NAB 2026, a wireless intercom system that fundamentally changes the infrastructure model by operating over public and private LTE and 5G cellular networks.

Rather than relying on on-site spectrum coordination, FreeSpeak Cell leverages carrier-grade cellular infrastructure to deliver full-duplex wireless intercom communications across areas and scales that would be physically impossible with conventional systems. The platform supports deployments of 100 or more beltpacks, scalable to hundreds of users depending on network configuration, and can extend coverage beyond a single building or compound — enabling communications across large properties, distributed campuses, or multi-venue productions without requiring additional on-site RF infrastructure.

Addressing the Spectrum Congestion Problem

In high-density live event environments — stadiums, convention centers, festival grounds, broadcast studio complexes — UHF, DECT, and Wi-Fi bands are routinely saturated by the combined presence of wireless microphones, IEM systems, production communications, and audience devices. FreeSpeak Cell directly addresses this congestion by routing intercom traffic over cellular networks that operate in separate, licensed spectrum. In the United States, the system additionally supports CBRS private LTE (Band 48), enabling venues to deploy a private LTE network for production communications entirely independent of public carrier infrastructure.

Global Radio Support and Dual SIM Flexibility

FreeSpeak Cell supports global radio bands spanning 700 to 900 MHz and 1700 to 4200 MHz, covering LTE and 5G deployment frequencies across North America, Europe, and Asia-Pacific. Dual SIM capability — supporting both physical SIM and eSIM — allows production teams to configure carrier redundancy, ensuring that a single carrier outage does not interrupt critical communications during a live broadcast or touring production. This resilience model mirrors the redundancy philosophy already standard in broadcast video transport and Dante audio networking.

Bob Boster, president of Clear-Com, framed the launch as a structural shift: the company is applying carrier-grade cellular infrastructure to professional communications, expanding both scale and coverage. For large-scale productions spanning multiple buildings, outdoor compounds, or multi-venue deployments, FreeSpeak Cell eliminates the need for distributed antenna systems (DAS) or extended DECT repeater chains — reducing both installation complexity and recurring spectrum coordination overhead.

What This Means for AV Integrators

FreeSpeak Cell opens a new tier of intercom specification for integrators working in stadiums, convention centers, houses of worship with satellite campuses, and outdoor live event venues — environments where legacy RF coordination has historically been a friction point in production communication design. As 5G private network deployments accelerate in large venues, integrators who can specify and deploy FreeSpeak Cell as part of a converged 5G AV infrastructure will be well-positioned to capture both the initial install and the managed services revenue that cellular-dependent production comms naturally support.
