An important step in establishing a working HetNet solution is
the effective co-location of different wireless solutions,
notably within cities with high population densities. Some
firms, such as HetNets Tower Corp., have developed unique
deployment methods for large city areas to facilitate a wide
range of wireless infrastructure elements, including small
cells, Wi-Fi installations, macrocells, femtocells, and
picocells. The company also points out the importance of
understanding local permit procedures for these smaller wireless
infrastructure installations and how such knowledge can minimize
the costs of building and operating a HetNet-based wireless
network.
