2. Introduction Corridor measurements made

Introduction
Corridor measurements made
Measurements were made at different times and location on the same and different corridors
The Saleh-Valenuela (S-V) model is used to model the desktop environment.
Key S-V model parameters such as Cluster Decay Factor, Ray Decay Factor, Cluster Arrival Rate, and Ray Arrival Rate are extracted from the measured data.

Measurement Setup
An Anritsu Vector Network Analyzer (VNA) was used to measure the channel transfer function.
The outputs of the amplifiers where connected to the antennas used in the experiment.
The two antennas were mounted on tracks and the directional receive antenna was attached to an electronically steerable platform that permitted the angle of the antenna to be precisely and automatically controlled
In this setup the VNA was set to sweep between 55-65GHz with a frequency step of 6.25MHz for 1601 data points.

Measurement Setup
An omni-directional antenna is employed at the transmitting side
A 21dBi directional pyramidal horn antenna at the receiving side.
The antennae voltage standing wave ratios were better than 1.5:1 over the entire frequency of interest.
The antennae were mounted on rails that permit the precise and automatic positioning required at 60 GHz (5mm wavelength).
For AoA measurements a directional antenna was mounted on an electronically steerable platform for precise angular measurements from 0 to 360 degrees in 4 degree steps.
For each angle the time impulse response was be measured.
