Currently, the standardization of 3G partnership project (3GPP) specifies next generation of cellular wireless networks to deliver broadband - like data rates. Besides MIMO and advanced antenna configurations, next generation cellular standards look into aggressive use of radio spectrum and advanced inter - cell interference (ICI) mitigation techniques to increase network capacity. In the former case, cellular operators have adopted the use of universal frequency reuse, that is, no frequency reuse among neighboring cells (and fractional frequency reuse at cell edge), and are considering the use of additional radio spectrum if necessary. However, with such an aggressive use of spectrum, ICI is fast becoming the limiting factor not only to the throughput performances of cell edge users but also cell throughput. ICI mitigation techniques are proposed to reduce or even avoid interferences altogether by coordinating decisions among multiple cellular sites.READ FURTHER AT: http://trends-in-telecoms.blogspot.com/2011/07/fiber-wireless-convergence-will-it.html
