Common management

• One of the key differentiators of LAA and LWA based systems is the integrated SON/Load balancing capability.

• Integration of RAN Assistance into NBIFOM will be critical for enhanced TWAG propositions to compete with LAA/LWA capabilities.

• When contrasting LAA and LWA approaches to license exempt integration into the access network, the key trade-offs in terms of requirements look to be around the enhanced neutral host capability of LWA, versus the lack of connection management functionality necessary for deploying LAA.
