In an era where connectivity is king, the critical role of wireless Radio Frequency (RF) spectrum in delivering communication services has never been more apparent. As a finite natural resource, competition for access to RF Spectrum is increasing along with global demand for communication capacity. Therefore, technologies enabling more efficient use of RF spectrum are essential to meet the global appetite for connectivity. RBC Signals is at the forefront of innovation in efficient RF Spectrum use, offering a flexible and efficient solution to these challenges: Dynamic Spectrum Leasing.
What is Dynamic Spectrum Leasing?
Dynamic Spectrum Leasing is a process by which traditional spectrum license holders provide non-license holders with temporary access to valuable, but unused spectrum in varied geographies for a specific and limited (minutes to hours) period of time at relatively low cost. This is in contrast with the existing practice of Static Spectrum Leasing, which provides non-license holders with dedicated access to static spectrum allocations in fixed geographies for long (typically multi-year) periods of time, at very high prices.
The regulatory and technical risks associated with offering Static Spectrum Leasing, along with its high cost for users, largely limit the practice. As a result, significant spectrum allocations remain unused while license holders develop technology, raise capital, or deploy their services.
Dynamic Spectrum Leasing benefits everyone. It enhances the utility of a finite natural resource, generates incremental revenue for license holders from unused spectrum assets while protecting their spectrum rights, and provides spectrum users with access to previously unavailable spectrum at a reasonable cost while they perfect their applications and business models.
How can Dynamic Spectrum Leasing be Used?
Here are a few early applications which leverage the RBC Signals Dynamic Spectrum Leasing STORM technology Platform:
Dynamic Spectrum Leasing Application: RF LEO/GEO Intersatellite Links (Go.BIC)
RBC Signals, in partnership with IQ Spacecom and Viasat, has announced the first application enabled by Dynamic Spectrum Leasing: a flexible and efficient solution for Low Earth Orbit (LEO) satellite operators to communicate with their satellites using Geostationary (GEO) satellite spectrum and power. This product, called Go.BIC, allows communication with LEO satellites even when out of view of traditional ground stations.

While the concept of LEO to GEO communication over RF is not new—exemplified by systems like the Tracking and Data Relay Satellite (TDRS)—the approach of dynamic leasing is groundbreaking. This new method allows service providers to offer cost-effective solutions by enabling the service on-demand and fractionalizing the beam. This flexibility means that more customers can access the service when they need it, without incurring the costs of constant connectivity.
Go.BICs potential for “always on” communication capability is especially important for expedited satellite commissioning in the Launch and Early Operations Phase (LEOP) of the mission when communication via traditional ground stations is limited.
Another application benefitting from Go.BICs “always on” communication is Rendezvous and Proximity Operations (RPO). These operations, conducted by satellite servicing missions, space tugs, and orbital debris removal spacecraft, are critical phases of each mission. Continuous connectivity during these operations is essential to avoid collisions and ensure spacecraft safety. Go.BIC provides the necessary connectivity, allowing operators to manage these delicate operations with greater confidence and precision.
Dynamic Spectrum Leasing Application: Enhancing Network Resiliency via Non-Terrestrial Networks (NTNs)
As communication technology advances, the importance of efficient and resilient connectivity grows. Data is regularly routed over multiple paths, including fiber, terrestrial wireless, and increasingly over satellite networks or NTNs. Dynamic Spectrum Leasing allows seamless integration of terrestrial and NTN solutions, previously hindered by the risks of spectral interference. This integration enables network operators to adapt to changing conditions and maintain high service reliability for commercial and mission-critical defense and security applications.
Conclusion
Dynamic Spectrum Leasing represents a transformative approach to spectrum management, maximizing the use of a finite resource and opening up new possibilities for connectivity. By allowing temporary, low-cost access to unused spectrum, it benefits spectrum holders, users, and the public alike. RBC Signals’ innovative applications, such as Go.BIC and enhanced network resiliency via NTNs, demonstrate the potential of this technology to revolutionize communication services. As demand for connectivity continues to rise, Dynamic Spectrum Leasing will play a crucial role in meeting global communication needs efficiently and effectively.
