The indoor hotspot propagation loss has been investigated for several frequency bands from 3.5 GHz to 73 GHz. The measurement campaigns were conducted in multiple different indoor offices world-wide. Analysis of these measurements reveals a number of underlying physical phenomena affecting the propagation behavior. A "Multi-zone propagation" concept is introduced to aid classification and analysis of the millimeter wave specific propagation characteristics. The propagation zones are indicative of differing interaction of the mm-Wave signals with the details of the environment. Many very close range measurements follow a free space propagation phenomenon. For longer LOS propagation, a waveguide propagation zone can be observed. For NLOS propagation, at least two scattering propagation zones can be observed. Together, understanding the environment and the multiple modes of propagation aids the coverage analysis for system deployments.
