Evolved Campus Connectivity

This chapter describes technologies used for in‐building/in‐campus localization using Real‐Time Location Systems, which may comprise a fourth communication overlay. It reviews some of the latest discrete technologies applicable to the campus environment, and presents a case for an integrated solution, both at the technology and at the administrative level. Wireless Nodes and Access Points constitute a Basic Service Set. Multi‐User Orthogonal Frequency Division Multiple Accesses allows for multiple‐user access by subdividing a channel into subchannels. Voice over Wi‐Fi utilizes Internet Protocol Multimedia Subsystem to provide a packet voice service delivered to the user over IP links via a local Wi‐Fi network. 5G cellular networks are being deployed around the world. The 5G system expands the 4G environment by adding new wireless capabilities but doing so in such a manner that long‐term evolution and New Radio can evolve in complementary ways.
