A smart antenna system with sub-sector dynamic capacity enhancement for mobile telecommunication networks

Dynamic concentration of the users within a part of a cell sector has placed pressure on network operators to find ways to dynamically optimise the sector to increase capacity and quality of service while maintaining coverage. Smart antenna systems have been identified as being capable of dynamically optimising the network. Network operators need to estimate the actual performance gain that can be achieved with this smart antenna system and a comprehensive knowledge of radio propagation effects is an important factor for the development and performance evaluation of mobile telecommunication systems. This paper presents a performance evaluation of this smart antenna concept within a realistic radio environment.
