We performed measurements in two different of parking buildings at a frequency of 1.8 GHz and proposed new upper- and lower-bound models. The actual breakpoint distance was shorter than theoretical one because of the effective floor height due to cars. These models also include time-variant effect, cars in parking area. This time-variant effect influence on the wave propagation very high. The results have shown that the upper- and lower-bound models will be useful for the system and cell design of indoor wireless communication systems. © 2005 IEEE.Mahidol UniversityEngineeringConference PaperSCOPUS
