Recommendation ITU-R P.1238-10

Propagation data and prediction methods
for the planning of indoor
radiocommunication systems and
radio local area networks in the
frequency range 300 MHz to 450 GHz

This Recommendation provides guidance on indoor propagation over the frequency range from 300 MHz to
450 GHz. Information is given on:
– basic transmission loss models
– delay spread models
– effects of polarization and antenna radiation pattern
– effects of transmitter and receiver siting
– effects of building materials furnishing and furniture
– effects of movement of objects in the room
– statistical model in static usage.
