After more than 30 years of working to promote information and communications technology in Africa, Nancy Hafkin was inducted into the Internet Wall of Fame. In an interview with APCNews, she shares the history of her work and that of communications technology in Africa, her interest in Africa, obstacles and achievements.
African countries lag behind the rest of the world in their use of Information and Communication Technologies (ICTs). To reduce the digital divide quickly and cost-effectively, wireless networks are considered. WiMAX (Worldwide Interoperability for Microwave Access) is a wireless broadband access technology that uses Orthogonal Frequency Division Multiplexing (OFDM) which is a multicarrier modulation scheme. OFDM presents a problem of a high crest factor or Peak to Average Power Ratio (PAPR). To circumvent this problem either High Power Amplifiers (HPAs) with large dynamic range or PAPR reduction techniques are used. The former scheme increases cost of the system while the latter introduces redundancy or distortion. A novel PAPR reduction scheme is presented. It is a combination of the ideas of Tone Reservation and Selected Mapping. The advantage of this scheme is that it has a lower complexity. It is simulated for a WiMAX system.
Lillian Nalwoga from the Collaboration on International ICT Policy in East and Southern Africa (CIPESA) coordinated research on open governance data in Uganda as part of APC’s Action Research Network project. “Citizens, academia, the private sector and civil society need to be more involved in the implementation of open governance,” says Nalwoga in an interview with APCNews.
APC reflects on a session at AWID Forum 2012 titled, “Bringing Gender to the Streets: Young Women Amidst the Arab Uprisings.” The use of internet technology like mapping to fight violence against women is an integral part of APC’s Take Back the Tech! campaign.
“Sex work may be illegal in Uganda, but providing services for sex workers is clearly not,” reads a statement put out on May 9 by WONETHA, a health and human rights organisation, in reaction to a serious crack-down on its activities by Ugandan municipal police.
The focus of the Mobile Africa report this time is on the overall innovation ecosystem, which includes a range of stakeholders: industry, entrepreneurs, government, academia, civil society, donors and multilateral organisations. The report also addresses the crucial role of innovator networks and incubators.
Internet is a vast tool which marked this century because it revolutionized and continues to impact the economy, social development and intellectual habits of several companies worldwide including people. Its use varies according to the behaviour of communities and the basic education received.
The Internet can strengthen human rights through the enhancement of the realization of freedom of expression, allowing people to receive information and seek to impart it as required in article 19 of the Universal Declaration on Human Rights.
