Tellumat’s base station power manager provides business as usual for shared electrical sites

Market need As municipalities continue to limit the number of cellular towers, shared base station towers are becoming increasingly common. Such installations accommodate multiple cellular network operators’ routing and signalling equipment, with the first operator to acquire the site usually taking on responsibility for sharing out electrical power to subsequent joiners. Under the combined impact…

Snoopy action at a distance – quantum theory can help spot stealth planes

Researchers at the University of Waterloo are using the quantum principle of entanglement – memorably called “spooky action at a distance” by Albert Einstein – to develop a quantum radar that can expose stealth aircraft and missiles. Unjammable radar Traditional radar is vulnerable to interference from space weather events such as geomagnetic storms and solar…

Time to step up – Business confidence beyond Ramaphoria

Many would have predicted the surge in business confidence when Cyril Ramaphosa became president of South Africa in December. Just as predictable was the inevitable dip back down in May.

Market need Many small and mid-sized airports in southern Africa face a difficult migration from ageing airfield ground lighting (AGL) systems. Typically based on dated analogue technologies, such systems rely on manual controls across airports to switch lights on and off and offer no feedback facility, forcing airport personnel to physically check lights in all…
