What is a near/far transmission problem? a. When one of two devices is closer to the AP and transmits at a higher output power, thereby overwhelming the signal of the more distant device, which is transmits at a weaker output level. b. When one wireless device cannot detect all other wireless devices in the WLAN because it is too far away. c. When an AP cannot communicate with another AP because it is either too close or too far away. d. When all wireless devices transmit at different power levels.
