Abstract
To understand the potential of indoor radio systems as communication media between portable computers and local area networks, the authors built a wideband indoor radio propagation measurement apparatus. The apparatus operates in the industrial, scientific, and medical (ISM) bands centered around 910 MHz, 2.44 GHz, and 5.8 GHz. They briefly describe the measurement apparatus, the measurement procedures, and the measurement areas in an academic environment, Columbia University. Complex multipath delay profiles were recorded in classrooms, small-room offices, open-layout offices, an auditorium, a library, and a machine room. The effects of both delay spread and channel dynamics on designing a high-speed indoor radio data transmission scheme are also discussed.Keywords
