The Wireless Access Providers’ Association (WAPA) has made a call to the Independent Communications Authority of South Africa (ICASA) to follow the example of other parts of the world by implementing lite-licensing in the local wireless access market.
In a statement released yesterday WAPA said Lite-Licensing is currently being trialed and employed by progressive institutions as an alternative wireless spectrum management approach. A local lite-licensing regime would improve spectrum efficiency, provide opportunities for new entrants to the market, and provide structure and management in the open spectrum space.
“A Lite-Licensing regime would provide a sustainable frequency sharing model in South Africa that could help raise spectrum efficiency and provide opportunities for new entrants, thereby driving the economy by creating jobs and facilitating broadband access,” said WAPA Chairperson Christopher Geerdts. “Lite-Licencing schemes provide the registration, coordination and interference protection benefits that a wireless license guarantees, but at a cost and application time significantly lower than traditional wireless licensing,” said Geerdts.
WAPA said it was willing to work together with ICASA to implement the lite-licencing solution and is uniquely positioned to facilitate the management of spectrum under a lite-licensing regime, without imposing undue financial or administrative burdens on the national regulator. In addition, should ICASA and the Department of Communication implement lite-licensing, with WAPA acting as advisor on the regime, there is a possibility that South Africa could export its wireless access framework solution to other African countries in the future.
“A properly managed lite-licensing regime will increase spectral efficiency, promote faster network deployment, meet the needs of industry and take a load off the regulator. WAPA urges the Department of Communication to recognise the value of lite-licensing in meeting its policy objectives and for the Independent Communications Authority of South Africa (ICASA) to implement it as part of the frequency management mix,” says WAPA regulatory advisor, Dominic Cull.
Most wireless access providers’ in South Africa currently make use of licence exempt frequencies in accordance with the ICASA Frequency License Exemption Regulations of 2008. The industry is growing exponentially to meet the massive, pent-up demand for cost-effective, quality broadband across the country – from high-density suburbs to remote rural communities. However, it is recognised that this is not a sustainable solution due to the number of new entrants seeking access to spectrum and the congestion of these allocated bands. “What our members have achieved is remarkable, given the limited frequency bands allocated and the minimal formal regulation of thos bands. It shows both the hunger for internet services and the passion to meet this need”, said Geerdts. Wireless access providers’ are in need of access to spectrum where they are afforded a formal interference protection by means of frequency co-ordination, as would happen in a Lite-licensing regime.
Lite-licensing is better than the ‘winner-takes-all’ approach currently adopted, which leads to dominance of the market by a few, large players, stifling innovation and competition as well as the current problem, where over 90% of spectrum is not used. On the other hand, lite-licensing introduces much-needed formalisation of spectrum allocation and interference control, which is absent in the bands currently used by most players. Offering such protection will unlock the barriers to far more substantial growth in the sector.
Lite-licensing works as follows. A central database keeps track of all current users and also monitors interference readings at each site. When an operator wants to deploy a new site, the geographic coordinates of that site are entered into the database and a spectrum-band ‘licence’ is allocated automatically. The operator then registers that site and spectrum allocation and also feeds back interference readings, which are used to verify the integrity of the solution. The licences can be free or attract a fee. The process is automated and objective, with interference monitoring taking place through built-in cognitive radios. Because the system is first-come, first serve, this approach favours the operators who are actually using the spectrum and leads to very efficient usage of spectrum.
According to Geerdts, this approach has been implemented by the regulator in the USA with strong partication by companies such as Microsoft and Google. There are numerous trials globally, ranging from the United Kingdom to Singapore, as well as the current trial in South Africa, in which WAPA is a participant.
WAPA is a self-regulated body that strives to ensure the sustainability of the wireless access services industry in South Africa, and represents a rapidly growing number of fixed wireless access providers, ISP’s and equipment vendors currently using, or with an interest in using, license exempt bands.
