Wireless services and wireless devices have become an important part of the people daily life. However, as the number of wireless devices increases, so does the density of co-located devices in home, office, industrial and public environments. This increasing density in combination with the emergence of more and more advanced wireless services, will demand a huge capacity from future wireless networks. In addition, a lot of these networks are sharing the same frequency band (e.g. WLAN, Bluetooth, ZigBee), which means that increasing the capacity is not just a matter of adding more wireless infrastructure.
