Abstract

Experiments were carried out within two differently constructed buildings using a 16 kb/s FSK (frequency-shift keying) modulator. A low-power transmitter broadcast a pseudorandom binary sequence (PRBS) from a low-level antenna (4.3 m) into the building. A mobile receiver traversing a preplanned route within the building along several floors recorded the field strength as well as the bit error structure, a real-time clock and distance information. The evaluation and analysis was done on an MS-DOS personal computer. Analysis of the results reveals statistical distributions from which formulas were derived to describe the propagation environment
