WCDMA Uu as new 3G Iub interface

This document presents a new way to carry the Iub traffic in a 3G system through the use of the Uu radio RLC, MAC and WCDMA protocol layers. So, instead of using leased lines, Ethernet, microwave, this system uses its own 3G frequency to carry the traffic between different Nodes B. On top of that, it is possible to form a meshed network among the Nodes B maximizing the use of the lub interface and providing the best experience to the end customers.
