Measurements and Models for the Wireless Channel in a Ground- Based Urban Setting in Two Public Safety Frequency Bands - Softcover

Inhaltsangabe

This is another in a series of NIST technical notes (TN) on propagation of radio signals for emergency-responder communications. This report describes measurements conducted in the urban environment with a vector network analyzer (VNA). The VNA yielded samples of the channel frequency response for multiple transmitter and receiver locations, and from these frequency responses (or channel transfer functions), channel impulse responses were derived. The channel impulse responses were analyzed and delay dispersion statistics were gathered for two types of channels- those with a line of sight (LOS) between transmitter and receiver; and those that were non-line of sight (NLOS).
