HetNets are next-generation networks, and will become the layer that brings the wireless infrastructure under a single network umbrella. HetNets will interconnect the small cell infrastructure, the macro infrastructure, as well as unlicensed technologies such as Wi-Fi, so the IoE can enjoy perpetual, unrestricted internetworking.
There are multiple types of access nodes. Wide-area HetNets will contain all the elements of a wireless network, across all deployment scenarios (indoor/outdoor environments, office buildings, homes, and underground areas). They support the multifaceted interoperability among macrocells, small cell, Wi-Fi network elements (hotspots, carrier Wi-Fi), in a mosaic of coverage that offers handoff capability among the network elements.
HetNets will integrate a number of new technology platforms, different from what is currently on the table. They will support much of what the IoE will require. They will include:
