The FCC proposes to dedicate 100 MHz of airwaves for small use, but not exclusively. Carriers would need to share it with existing government users. The high-frequency band would be ideal for small cell deployments, but carriers don’t like sharing.
The heterogeneous network, or HetNet, will turn today’s big-tower cellular systems into dense, multi-layered and tremendously high capacity networks. Given the complexity of such systems, it’s easy to imagine HetNet as a technology of the future, but Ericsson CEO Hans Vestberg says you would be wrong.
