Enterprises are adopting smart building technologies to reduce costs and streamline operations. Wireless sensors will monitor everything from heating and cooling to lighting, office machines, and security controls. These sensors need robust and reliable wireless connectivity. There are several requirements for providing the needed wireless connectivity.
Ubiquitous wireless coverage is the first requirement. Sensors can be anywhere in a building, and the outdoor macro wireless network doesn’t always penetrate building walls to provide the needed signal strength. In fact, a recent Zinwave survey showed that 74 percent of workers complain about poor in-building wireless service for their cell phones, so the current state of affairs is clearly inadequate for supporting the IoT, at least when cellular frequencies are being used.
