Wi-Fi, the well-known standard for wireless Internet, is reaching its technical limits. Its efficiency drops significantly in busy surroundings where many different networks and numerous wireless Internet-enabled devices are operating. In some cases, it may even drop to less than 20%. This has emerged from exploratory research being carried out by the University of Twente's CTIT Research Institute, on behalf of Radiocommunications Agency Netherlands. The increasing demand for bandwidth means that the efficiency of Wi-Fi is likely to fall still further in future. For this reason, the researchers think that we should consider the option of a new Wi-Fi standard.
