Abstract :
In this work the characteristics of the radio channel of a typical industrial environment are examined in detail by means of experimental measurements. The channel impulse response is measured at several representative positions. These measurements are then used to calculate important propagation parameters like attenuation, rms delay spread and coherence bandwidth. Furthermore, directional antennas are used to investigate the effect of directional transmission in propagation parameters. Finally, the performance of direct sequence spread spectrum (DSSS) radio transmission (in the 2.4 GHz band) is evaluated for omnidirectional and directional reception by means of bit error rate (BER) measurements at the same characterized positions
