Social Media – Much More Than An Issue of Public Relations

Many businesses are trying to adjust to and cope with what sometimes seems like a “perfect storm” of rising costs, stagnant or declining markets, regulatory and policy changes, a credit crunch, and in some sectors uncertain or even declining product pipelines and expiring patents (think pharmaceutical) and/or contentious issues of intellectual property rights (think ICT),as well as major shifts in demographics. These forces are driving significant shifts in how many products and ser vices are developed, marketed, sold, and delivered.

Japan as an example of Green IT

Japan is an example of how long term forecasts of potentially huge increases in energy consumption and CO2 emissions are stimulating Green IT initiatives both to reduce the energy required “per byt

Wireless Applications and Opportunities – A Push-Pull Relationship with Health Care


Important opportunities to improve health care for both curative and preventive purposes are being developed that are aimed at improving connectivity and communication between patients and their care providers. These opportunities necessarily include as one element connectivity to and from medical devices and systems.

Mobile WiMAX and its Shrinking Ecosystem

Over the past months a series of events and decisions by leading wireless equipment suppliers raises doubts about which and how many among them will be devoting significant efforts and investments, and giving high priority to the development and commercialization of future generations of mobile WiMAX equipment beyond current TDD systems.

Reductions in Mobile Interconnection Rates in South Africa - When and How, Not Whether

Mobile interconnection rates in South Africa and consequently the prices of mobile telephone calls are unquestionably very high by international norms and practices, and well above the costs that c

South Africa and the 2.6GHz Band Plan – Isolation or Harmonization

Martyn Roetter, July 24, 2009

South Africa has an opportunity through its allocation and attribution of spectrum in the valuable 2.6GHz band (2500-2690MHz) to become a broadband wireless pacesetter for its own economic and social benefit, as well as Africa’s.

Spectrum, Spectrum, Spectrum

A key question on everyone’s minds is how to improve broadband service and penetration, and accelerate our ICT development index in the process. Service providers are exploring a variety of wireless technologies. Mobile operators, with their aggressive investment plans and marketing muscle, have already demonstrated their ability to make a major difference. Convergence now means fixed line players are also investigating and deploying the same technologies – e.g. Telkom’s W-CDMA rollout. As the old adage goes the three most important priorities in this regard are (a) spectrum, (b) spectrum and (c) spectrum.

Too late for WiMax?

Next generation mobile technology could relegate WiMax  to a niche position in Africa as a wireless broadband solution in a continent that has a higher penetration of mobile phones with internet access than fixed lines.

WiMax will face stiff competition from mobile networks, although it will still have a greater impact in those developing countries in which it is given a reasonable head start over mobile broadband networks in Africa – by mid-2008 there were already 14 commercial HSPA networks in nine African countries.
