Abstract

A communication networks including a plurality of small cell providing air interface infrastructure functionality is provided. Aspects of the present disclosure relate to the management of inter-small cell communication in accordance multiple air interfaces supported within individual small cells. Additionally, aspects of the present disclosure relate to the management of intra-small cell communication in accordance with communication networks implementing multiple small cells. In other aspects, small cells coordinate handovers through the use of a controller, or by leveraging wireless connections created between the small cells. In further aspects, the small cells enable the utilization of multiple air interface standards within a small cell.
