Abstract

IUO (intelligent underlay-overlay) in a combination with random frequency hopping in GSM is analysed. Several improvements to the original IUO concept analysed in Nielsen et al. (1997) are introduced. With the improved IUO concept it is possible to load a network configuration consisting of 4 regular frequency channels and 3 super layer channels almost to the hard blocking limit. A capacity gain of more than 40 percent compared to a one layer frequency hopping 3/9 reuse network has been found
