Characterization and Evaluation of a Commercial WLAN System for Human Provocation Studies

Figure 6

Dependence of measured electric field at  cm on the frequency (channel number) for R52 (solid line) and R52n (dashed line) router board cards under test with UDP mode and one active antenna in vertical position. Asterisks mark channels where performance breakdown occurs (meaning that the card was unable to send data at the full data rate). Error bars represent mean ± standard deviation.
