About Dynamic Spectrum Alliance

The Dynamic Spectrum Alliance (DSA) is a global, cross-industry, not-for-profit organization advocating for laws, regulations, and economic best practices that will lead to more efficient utilization of spectrum and affordable broadband for all.

The DSA advocates for policies that promote unlicensed and dynamic access to spectrum to unleash economic growth and innovation. DSA gathers the interests of its members, collates resources and leads international advocacy actions on dynamic spectrum access. DSA has a close relationship with spectrum authorities worldwide, attends regional meetings and engages with authorities to achieve flexible and innovative spectrum regulations on a national basis to increase innovation and affordable connectivity.

Our membership spans multinationals, small-and medium-sized enterprises, as well as academic, research and other organizations from around the world. DSA members include top technology and telecom companies worldwide including 5 of the top 10 largest companies in the world. Members collaborate and work together to progress the technologies and techniques to improve dynamic spectrum access worldwide. A full list of Dynamic Spectrum Alliance members is available on the Dynamic Spectrum Alliance’s website at www.dynamicspectrumalliance.org/members.

Consumer demand for wireless connectivity is surging and spectrum is a finite source. It is critical to intensively share underused spectrum bands. Today, developing technology is allowing for spectrum to be shared in dynamic and efficient ways to maximise connectivity potential of spectrum worldwide.

The DSA attends many events and workshops which contribute to spreading awareness of the importance of Dynamic Spectrum Sharing. Several of these are held specifically to provide a platform for collaboration between entities for the purpose of regulation revision. The DSA have, so far, worked with multiple unions to pitch legislation changes with great success. We have also founded our own annual Global Summit, leading by example to create a space for regulators and industry professionals alike to collaborate and discuss the current use of spectrum. You can read more about the upcoming Global Summit on our dedicated page here.

The Dynamic Spectrum Alliance advocates for a variety of different technologies that allow for dynamic access to spectrum. As technology develops to adapt to the needs of the market, we support and promote technologies that will help. Our focus is ensuring that the legislative and regulatory framework is there to support that diversity of technologies. Some examples of technologies using dynamic spectrum access are:

TVWS Supports increasing shared spectrum use in TV whitespace that enables cost effective broadband deployment in unserved or underserved rural areas and IoT. License-exempt broadband services in TVWS are up and running, regulatory frameworks are in place, the technology is proven, standards exist, radios have been certified, and commercial deployments are underway.

CBRS Supports CBRS because it is a spectrum-sharing success story. The three-tier sharing model in the U.S. enables the most efficient and intensive use of mid-band spectrum that’s critical for 5G. Using database and location identification technologies protects incumbent services, and Licensed access and general access provide opportunities for large and small entities to promote greater deployment.

C-Band (3.7- 4.2 GHz) The DSA has long advocated for policies that lead to the efficient and fair use of the band and supports the proposal for a public auction in the U.S. DSA has made a point-to-multipoint sharing proposal, which can provide tens of millions of underserved rural Americans broadband services in a short timeframe.

5.9 GHz and 6 GHz The 6 GHz band presents a golden opportunity for more efficient spectrum use and it is very important to maintain the technology neutrality. DSA supports unlicensed access to the band in order to meet the demand for Wi-Fi and unlicensed wireless devices that require larger channel bandwidths and will be crucial for the 5G ecosystem.

mmWave The propagation characteristics of mmWave bands make dynamic sharing ideal and critical to enable efficient use of spectrum. DSA supports unlicensed use of the 57 - 71 GHz band, including Wi-Gig and point to multipoint mesh network services. Additionally, DSA supports flexible licensing rules like those adopted by the FCC in the 37 GHz band.

The DSA works globally and is designed to be a flexible and effective partner for regulators around the world. The DSA headquarters are located at the following address: Dynamic Spectrum Alliance 3855 SW 153rd Drive Beaverton, OR 97003 United States

About Dynamic Spectrum Sharing

Radioelectric Spectrum describes the range of radio frequencies which wireless devices can use to transmit and receive information. Devices that use the spectrum to communicate range from radios to Wi-Fi to mobile phones, satellites and remote controls. Some ranges of frequency (bands) are more suitable for particular uses than others. In order to manage access to spectrum, spectrum authorities allocate different bands of frequencies for different services and establish technical rules to minimize the likelihood of harmful interference. According to spectrum allocation, some bands of spectrum can be licensed for the exclusive use of certain entities and for specified purposes. Some bands are also set aside for shared use on an unlicensed or license-exempt basis.

Dynamic Spectrum Sharing is an umbrella term used to describe a set of technologies and techniques that enable radio communications devices to opportunistically access certain frequency bands and make an efficient use of the radio spectrum. This includes enforcing spectrum regulations and developing devices to identify available bands for more signals to be transmitted whilst protecting incumbent users. These technologies and techniques ensure that consumers and their devices have wireless bandwidth when and where required. The DSA have always been a strong advocate for this approach. Too often, spectrum is seen as a tool divided between licensed and unlicensed access to spectrum. By viewing spectrum as a naturally shared resource, protecting incumbent services and considering costs and other benefits, an appropriate spectrum sharing criteria is developed which facilitates the efficient spectrum use. Providing connectivity to those who need it and strengthening communication methods already in place for the benefit of communities worldwide is of top priority for the DSA. The DSA is the only global organization focused on promoting spectrum sharing innovation to get the most out of our wireless resources and advocates for policies that promote unlicensed and dynamic access to spectrum to unleash economic growth and innovation.

TV White Spaces (TVWS) are the unoccupied channels of spectrum in the VHF and UHF frequency ranges globally allocated to broadcast. Since these are left empty, they can be utilised for broadband deployment on an unlicensed basis. The sustainable nature of this type of spectrum use makes it very cost efficient to implement, which is extremely beneficial for rural, underserved and developing areas. The effectiveness of TVWS technology has been proven and commercial deployment is underway following the completion of its regulatory framework in many countries around the world. The DSA supports this movement greatly as it prevents wasted spectrum and promotes accessibility to Internet, meeting current user demands whilst transforming the lives of the unconnected.

There is constant development happening in the world of telecommunications regulations, and the DSA is proud to be a part of the ever-progressing movement toward global connectivity. You can read more about the DSA’s work and keep up with industry news on our News Page.
