問題文
An auditorium needs each access point to serve the clients nearest to it and to leave the distant ones to a closer unit. The team turns to the receiver threshold of the radios. Which change has that effect at 5 GHz?
選択肢
- Move the threshold from -80 dBm toward -76 dBm, because a radio that demodulates just the stronger packets behaves as a smaller receiver cell and hands the weaker links to a unit that is nearer.
- Move the threshold from -80 dBm toward -76 dBm on the radios of 2.4 GHz, because that band shares the same set of values and hands the weaker links to a unit that is nearer.
- Move the transmit power from -76 dBm toward -80 dBm, because a radio that sends at a lower level behaves as a smaller receiver cell and hands the weaker links to a unit that is nearer by that setting.
- Move the threshold from -76 dBm toward -80 dBm, because a radio that demodulates weaker packets as well behaves as a smaller receiver cell and hands the weaker links to a unit that is nearer by that setting.
