Rare is the campus with total coverage of cellular service. Maybe the problem surfaces for your institution in its basement-level spaces, or that oldest building on campus with walls built to bomb-shelter standards, or the newest, LEED-certified facility that uses energy-efficient glass or other construction materials that block radio frequency. Whatever the site or cause, it’s a big problem. Most mobile traffic originates inside buildings (ABI Research pegs it at more than 80 percent), so people get frustrated when they can’t use their devices to make a phone call — particularly in an emergency. What’s needed is a service that’s as simple to use as cellular but as pervasive and inexpensive as WiFi. 3.5 gigahertz Citizens Broadband Radio Service (CBRS) may be the answer. This frequency could provide a cost-effective link between cellular and WiFi.
