For over 5 years, Microsoft has been working with industry and government partners around the world to demonstrate the viability and potential of Dynamic Spectrum and TV White Spaces. The viability of the technology has been proven in over a dozen trials and commercial deployments around the world – ranging from remote villages of Africa to the dense urban centers of Asia. To learn more about these pilots and deployments, search by geography below.
Kenya Commercial Pilot
Microsoft Corp., in collaboration with the government of Kenya’s Ministry of Information and Communications and Indigo Telecom Ltd., launched a pilot project delivering low-cost wireless broadband access to previously unserved locations near Nanyuki and Kalema, Kenya. Launched in February 2013, the network utilizes TV white spaces and solar-powered base stations to deliver broadband access and create new opportunities for commerce, education, healthcare and delivery of government services.
The project is the first deployment of TV white space technology in Africa targeted at communities without access to broadband or electricity and is a result of a memorandum of understanding that presents a framework of cooperation between Microsoft, the Kenyan Ministry of Information and Communications and industry partner Indigo Telecom. To date, work in this space in Africa has exclusively focused on demonstrating the technical feasibility of using TV white space technology. This project takes an important next step forward by instead focusing on assessing the commercial feasibility of delivering low-cost access using TV white space technology.
The initial installation near Nanyuki includes five customer locations: the Burguret Dispensary (healthcare clinic), Male Primary School, Male Secondary School, Gakawa Secondary School and Laikipia District Community Library. The installation in Kalema will begin with a base station that connects to a government of Kenya agricultural extension office. Fourteen more locations on the network will be added. The network will also feature white space radios manufactured by Adaptrum.
This pilot is part of Microsoft’s broader 4Afrika Initiative, to help improve the continent’s global competitiveness. A core goal of the 4Afrika Initiative is to facilitate access to technology for the masses and to empower African students, entrepreneurs, developers and others to become active global citizens.

Tanzania Commercial Pilot
At the World Economic Forum on Africa in May 2013, Microsoft announced a new pilot in Dar es Salaam, Tanzania. Microsoft will partner with the Tanzania Commission for Science and Technology (COSTECH) and local Internet service provider UhuruOne utilizing TV white spaces to offer affordable wireless broadband to university students and faculty. Through the pilot, students and faculty will also be able to access Windows 8 device and service packages. The pilot’s initial deployment will target the University of Dar es Salaam, among others.
Much like our commercial pilot in Kenya, this project is part of Microsoft’s 4Afrika Initiative and is designed to assess the commercial feasibility of offering affordable wireless broadband through TV white spaces. The pilot in Tanzania, however, is specifically focused on urban deployment and delivering an integrated device, service and connectivity solution to university students.
In addition to offering these comprehensive solutions, the pilot will hire a team of students as on-campus support staff for the network infrastructure. These students will have the opportunity to learn valuable technical skills and gain qualifications for IT-related career paths.
The pilot group members are: Tanzania Commission for Science and Technology (COSTECH), UhuruOne, and Microsoft.
South Africa Commercial Pilot
In July 2013 Microsoft launched a pilot project in rural Limpopo that aims to deliver high-speed and affordable broadband to underserved communities using TV white spaces technology. The focus of the pilot will be to prove that TV white spaces can be used to meet the South African government’s goals of providing low-cost access for a majority of South Africans by 2020.
The pilot is a joint effort between Microsoft, the Council for Scientific and Industrial Research (CSIR), the University of Limpopo and network builder Multisource. It will use TV white spaces to provide low-cost wireless broadband access to five secondary schools in underserved parts of the Limpopo province.
The project will use the University of Limpopo as a hub for a white space network deployment that will provide nearby schools in local communities with wireless connectivity. The project will also provide each of the five schools with Windows tablets, projectors, teacher laptops and training, education-related content, solar panels for device charging where there is no access to electricity, and other support.
Singapore Commercial Pilot
Singapore White Spaces Pilot Group (SWSPG) was established in April 2012 with support from Infocomm Development Authority (IDA). The objective of the group is to deploy White Spaces technology pilots in Singapore, thereby accelerating the adoption of White Spaces technologies globally. SWSPG aims to attract broad members from public and private sectors, local and international industry, academic and research institutes and end-user organizations that could benefit from this next generation broadband wireless connectivity.
The original group has expanded in 2013 to 18 members and has added five new projects to the original three, each demonstrating the variety of commercial services that could be deployed using White Spaces technology in a terrain where traditional wireless deployment would be difficult to achieve:
• Singapore Island Country Club: The country club will use the new technology to optimize the connectivity and deploy smart sensors, which will help it monitor the moisture of the golf course and track golf buggies among other uses.
• Changi district around the airport: During the time in port, vessels rely on satellite connectivity for their crew to access e-mail, Internet, and voice communication services, but this mode of wireless connectivity is costly and subject to time delay depending on weather conditions. White Spaces technology will provide a cheaper and more reliable alternative.
• National University of Singapore: The third commercial deployment is a collaboration between I2R and Power Automation to allow the National University of Singapore (NUS) to meter the use of air conditioners and charge hostel residents according to their usage.
• Gardens by the Bay: Singapore’s iconic attraction has undertaken a TVWS trial to provide Wi-Fi connectivity to its visitors in a reliable and cost-efficient manner. Currently three different sites at Gardens by the Bay – Supertree Grove, Meadow and Canopy - offer TVWS based Wi-Fi connectivity to visitors.
• Sentosa: Singapore’s island resort is implementing a trial to deploy security surveillance cameras at Siloso Beach, Belawang Beach and the Merlion complex, while demonstrating the co-existence of multi TVWS vendors in a single environment.
• Housing & Development Board (HDB): This pilot project responds to a need for video surveillance for rooftop security, car park enforcement and getting real time video from the lift system in HDB buildings. TVWS technology is expected to add efficacy in getting real time coverage, which would result in enhanced security and safety for the residents.
• Eurokars Group: Singapore’s flagship car dealership will use TVWS to cost effectively extend their IT network to a number of outlying buildings. This will be complemented with unique concierge services: test-drive vehicle tracking and customer scheduled service management.
The Pilot group members are: Adaptrum, Eurokars, Grid Communications, HDB, iconectiv, Institute for Infocomm Research, Neul, NexWave, National Institute of Information and Communications Technology (NICT), Power Automation, the Singapore Island Country Club, Sentosa Development Corporation, Spectrum Bridge, StarHub, ST Electronics, Terrabit Networks, ZDW Systems, and Microsoft.
TV White Spaces Trial in the Philippines
In July 2013, Microsoft entered into a partnership with the Philippine Department of Science and Technology’s Information and Communication Technology Office (DOST-ICT Office), Department of Agriculture’s Bureau of Fisheries and Aquatic Resources (DA-BFAR) and the U.S. Embassy Manila’s United States Agency for International Development (USAID) to explore delivering broadband connectivity to remote areas in the municipalities of Talibon, Trinidad, Bien Unido, Ubay and Carlos P Garcia. Results will be gathered and considered for potential expansion in 2014.
The target of the trial are fishing communities in particular, as the initiative will allow local government units to access the BFAR’s Fisherfolk Registration System (FRS) directly from the field, enabling municipalities to immediately distribute critical IDs, certificates and licenses to the fishermen that need them. Additionally, field operatives from the Philippine National Police, Bantay Dagat, and BFAR will be able to immediately access and connect to a central database to monitor compliance.
The registration, supported by USAID’s Ecosystems Improved for Sustainable Fisheries (ECOFISH) Project, will enhance the Philippine Government’s economic assistance to the fisheries sector, focusing on sustainable practices that seek to restore the health of the ecosystem to produce more fish, feed more people, and generate more jobs. The partnership will also provide internet access for the target municipalities. Public institutions such as clinics, public schools and barangay halls will be transformed to e-knowledge hubs and will serve as mobile registration centers especially for fishermen located in remote areas.
Cambridge White Spaces Trial
Launched in June of 2011, the Cambridge White Spaces Trial was designed to evaluate both the technical capabilities of the technology as well as potential end user applications and scenarios. The consortium explored and measured a range of applications, including rural wireless broadband, urban pop-up coverage and the emerging “machine-to-machine” communication, and found TV White Spaces can be successfully utilized to help satisfy the rapidly accelerating demand for wireless connectivity.
· To test city center coverage the consortium set up base stations in four pubs and a theater, seeking to provide widespread coverage including “pop-up” Wi-Fi hotspots. The tests showed that TV White Spaces can extend broadband access and offload mobile broadband data traffic. These hotspots can enable users to enjoy data-intensive services such as online video provided by BBC iPlayer and Sky Go during peak usage times, when additional capacity and wider reach is needed. The tests also demonstrated that coverage was extended much further and with less interference than conventional 2.4 GHz Wi-Fi.
· Rural connectivity was also a key priority for this trial. The residents benefited from radical improvements in their broadband service, up to 8Mbps net speed achieved over 5.5km links, within an 8 megahertz bandwidth, using a modified, prototype version of the Neul Weightless technology. Results led to anticipation that further optimization could see speeds greater than 20Mbps.
· To test the machine-to-machine scenario, BT and Neul developed an application that would send an alert message to the city council when dustbins were full and needed to be emptied. This helped reinforce the belief that TV White Spaces are uniquely positioned to unlock the potential promise of the Internet of Things.
The trial completed in April of 2012 after more than 10 months of comprehensive testing in urban and rural areas in and around Cambridge. By any measure, the trial was a success. The trial verified that Cambridge has significant TV White Spaces capacity – upwards of 20 white spaces channels corresponding to 160 megahertz in total. The key scenarios were validated, technical validation was sound and exceeded expectations and there were no unforeseen impediments or hurdles. Based on the results, the consortium recommended that Ofcom complete the development of its regulatory framework to enable the commercialization of the technology.
The enthusiasm for the trial was captured by the UK’s Communication Minister Ed Vaizey who commented “I welcome the success to date of the Cambridge White Spaces Trial. Leading innovators from the UK and beyond have demonstrated the potential that television white spaces can have for meeting the UK’s broadband needs. Developments such as this endorse the leadership position that the UK can take in enabling more efficient use of spectrum by opening up an array of opportunities for wireless applications for consumers and businesses alike. I find the idea of using white space devices to deliver broadband to rural communities, or to expand the range and quality of urban Wi-Fi hotspots, exciting. This can form a significant contribution to our thinking as we consider how to maximize the value of the spectrum below 1 GHz. “
Claudville, Virginia, September 2009
Microsoft participated in the first US deployment of TV White Spaces in Claudville, Virginia. The White Spaces trial there offers both an alternate broadband network as well as a model by which the government might be able to better utilize scarce spectrum resources available to it for delivering ubiquitous mobile broadband.
Initially, the TDF Foundation funded the construction of a computer lab with high-speed Internet. Due to the distances between locations and dense foliage in the area, extending broadband further into the community via fiber or copper lines was impractical and cost-prohibitive. At this stage Microsoft partnered with Dell and Spectrum Bridge to connect Claudville’s post office, several businesses and homes, and Trinity Christian School to the fiber optic backbone using prototype wireless White Spaces equipment under an experimental license granted by the FCC for 18 months.
Using existing infrastructure, the Spectrum Bridge installed its software application on a White Space radio at locations throughout the service area. These radios were set up at the local school and the café located in the business district. Dell and Microsoft donated the computers and software installed in the school’s classrooms. The initial deployment provided access to broadband, finding available TV White Spaces in the locations required; determined channel availability including contiguous and non-contiguous channels and provided real-time updates to move users in the event of incumbent use.
"I hope that Claudville will become a model for delivering broadband services to more rural communities in a cost-effective manner in the future," Rep. Rick Boucher (D-Va.), chairman of the House Subcommittee on Communications, Technology and the Internet, said in a statement.
Switzerland, October 2012
In October 2012 Microsoft worked with the Swiss regulators to demonstrate the potential of TV White Spaces technology for unlocking heretofore unused TV band spectrum to deliver broadband-grade voice, data, and video applications. With our partners Neul, the University of Strathclyde, Steepest Ascent, and Inveneo we specifically focused on showcasing the practical utility of using cognitive radio systems to access unassigned TV channels without causing interference to television broadcasts and other licensed operations.
The temporary license from the Swiss Federal Office of Communications allowed us to connect Neul’s base and client station and Microsoft Research’s prototype TV White Space database to form a White Space system. The latter allowed the base station to act as an access gateway for connecting the client station, and subsequently the XBOX360 to the Internet. Once online, the users could use the XBOX to conduct any activity they would using a traditional broadband connection, including browsing the Internet, streaming live HD videos and playing online computer games. Moreover, we looked to test some more challenging applications, such as a simulated wireless microphone registration, the blocking of an available channel, and seamless TV band channel switching. Throughout the process a spectrum analyzer monitored the spectrum use and found no disruptive interference.
UN RIO+20 Summit, June 2012
At the UN Rio+20 Summit in June 2012, Microsoft demonstrated the potential of TV White Spaces in providing high throughput Wi-Fi for rapid deployment scenarios, such as disaster relief.
Our demonstration showed how the use of a base station and client devices can opportunistically leverage TV band White Spaces to significantly expand the rapid deployment kit’s terrestrial network coverage – providing just the kind of almost-instant wide area network so critically needed in these situations. Some of the advantages to using White Spaces include a 3-10x increase in distance covered and the ability to transmit through walls and other barriers that normally stop Wi-Fi.
For the purpose of demonstration we featured the emergency.lu rapid response platform, which has been designed to help the relief teams in the field (re-)establish broadband access for first responders. It provides a satellite infrastructure and capacity, communication terminals, and rapid deployment logistics and was developed as a public-private partnership by the Luxembourg Ministry of Foreign Affairs, Skype, HITEC Luxembourg, SES Techcom and Luxembourg Air Ambulance. We have received extremely positive feedback, not only from the government representative present, but from the non-governmental organizations that would typically be deployed when disasters hit.
In delivering the demonstration we partnered with Neul, which develops wide-area wireless network technology dedicated to Machine-2-Machine traffic and designed to operate in the TV White Spaces part of the spectrum range.
Asian Development Bank, May 2012
During the 45th annual meeting of the Asian Development Bank Board of Governors in May 2012 in the Philippines, Microsoft demonstrated the potential of Super Wi-Fi networks using TV White Spaces technology.
Our demonstration ran for all three days of the conference and the outcomes exceeded all expectations and resulted in substantial interest in the technology from government stakeholders and telecom regulators. Upon an invitation from the government of the Philippines, Microsoft also presented the TV White Spaces technology to them and discussed the possibilities its usage could open up for a country such as the Philippines when it comes to affordable internet access. Traditional broadband deployment represents a significant cost in geographies consisting of islands, and the superior range and coverage of TV White Spaces could allow the Philippines to connect most of its underserved communities to broadband services.
In delivering the demonstration we partnered with Adaptrum, a Silicon Valley based company that develops wireless broadband solutions and market-based mechanisms to enable new multi-use network infrastructure and service models. Adaptrum’s TV white space solution was recently certified by the FCC for commercial deployments in the U.S.
Inter-American Development Bank, March 2012
Microsoft demonstrated the use of TV White Spaces technology at the Inter-American Development Bank (IDB) Annual Meeting 2012. We looked to showcase the real world utility of the technology to a group of stakeholders that make investment decisions for state infrastructure projects, including broadband deployment, all across Latin America.
During the demonstration we used TV channels 19 and 26, which was assigned to us by the Uruguayan spectrum regulation agency URSEC for temporary use. In delivering the demonstration we partnered with Adaptrum, a Silicon Valley based company that develops wireless broadband solutions and market-based mechanisms to enable new multi-use network infrastructure and service models. Using their base and client stations, we showed how these would interact with Microsoft Research’s prototype TV white space database using the assigned channels. The end result was a clear and powerful TV White Spaces connection, which allowed the client side devices to stream live HD movies from Netflix, perform Skype calls and browse the Internet.
Kenya, September 2011
Microsoft is working with the Kenyan government to deliver solutions that can unlock heretofore unused TV band White Spaces to deliver low cost broadband solutions to underserved and unserved communities. In our demonstration in September 2011, we partnered with the hardware supplier Adaptrum to showcase the use of this disruptive technology to government stakeholders – the first time this has been done anywhere in Africa.
Using Adaptrum’s base station and client device and a prototype White Spaces database developed by Microsoft Research, we formed a White Space system where the base station is connected directly to the Internet and acts as an access gateway to connect the client station to the Internet over a broadband connection. Such a connection can also be used to conduct video chat sessions. Throughout the process a spectrum analyzer monitored the spectrum use and found no disruptive interference.
