Examples of Mobile network Sharing can be found in both mature and developing markets, with 3G providing an added impetus to assess the commercial and regulatory viability of network Sharing may take many forms, ranging from passive Sharing of cell sites and masts to Sharing of radio access networks (RANs) and other active elements such as network roaming and the SharingShared CompoundAntenna ANetwork ABTS/Node BNetwork ABSC/RNCAntenna BNetwork BBTS/Node BNetwork BBSC/RNCCore N

• Core network sharing. Passive sharing is usually defined as the sharing of space or physical supporting infrastructure which does not require active operational co-ordination between network operators. Site and mast sharing are considered to be forms of passive sharing.
