Smart Cities Dive reported on meeting customer demand for in-building mobile connectivity, where it named Crown Castle a “neutral host.” A neutral host is a company that sells IBW as a managed service to the building owner or enterprise. “Companies like ATC, Boingo, Crown Castle and ExteNet all shoulder the cost of deploying and maintaining the IBW network in return for a monthly lease fee. This approach is attractive to enterprises, as it changes the cost from a capital expense to an operating expense and lets them spread out the cost of the system over a long period of time,” the article states.
