Russian Market: Looking into the Future Worldwide fiber optical cables market is growing, but the Russian market is reducing production and consumption volumes. In that context domestic producers have to preliminary solve a challenging task for providing high quality and encouraging competitive ability of their products to afford Russian customers favorable terms and not sacrifice at that the products quality and assortment.

Ultr-wideband Devices. Market and Its Regulation in USA From the date of decision to legalizate ultra wideband (UWB) unlicensed radio systems passed more then ten years. During this time UWB systems operation was provided by statute in Russian Federation, Canada, Europe, South Korea, Taiwan and other countries. Now time is ripe to preliminary summarize this decision in terms of UWB systems that obtained USA electronics market access analysis.

Modern Wi-Fi. Are All Access Points Equally Well-behaved? Traditionally Wi-Fi is considered to be a second-class as not a very fast network attachment. Advanced developments have changed our idea about how fast and reliable can be a Wi-Fi connection/ Some technologiea can provide throughput that exceeds standard values by an order of magnitude.
