“…It is clearly depicted that 2450MHz has large SD with respect to 900 MHz and this deviation increases with the number of people and a maximum of 6 dB is observed but it increased . This can be explained by another way, at R1 or R2 the signal power is distributed with large multipath therefore any movement between antennas causes only small fluctuation in power, opposite phenomena can be described at R3 or R4 locations as it was also concluded on [5]. So, it can be noticed that the change of MRP and SD with regarding degree of motion strongly depends on the level of time invariant received power rather than on operating frequency.…”

The effects of people movement in fixed indoor communications, known as temporal variation, are studied at 900MHz and 2450 MHz with undertaking experiments in an office/laboratory environment. Intentional and unintentional (natural activities such as meeting, social gathering, etc.) temporal variations were examined with regard to various important parameters (i.e. mean received power, standard deviation, dynamic range of fluctuation, level crossing rate, average fade duration, etc.). In particular, it is found that the amount of dynamic range of fluctuation, mean received power and standard deviation change more likely depending on the level of time invariant received power (in a static environment) rather than on operating frequency. The results presented here could be meaningful for designing a robust fixed digital transceiver; in addition it can lead to model a simulation tool to analyze the temporal variations under diversified sets of conditions.
