E.g. Multi-hop system based on the same technology or a mixture of different radio technologies. Mesh network: more than one possibility to forward data from the user to the network RAT X Bearer service / connectivity: provides pure point-to-point link Provides more than connectivity: e.g. Mobility support, Authentication, QoS, Security Session Continuity / Terminal Mobility required
