Transmitting station’s output power

Receiving station’s output power

NEW QUESTION 92
In an infrastructure Basic Service Set (BSS), how does the passive scanning process occur?

Access points broadcast Beacons on all channels of each radio within the regulatory domain.
Nearby client stations record information found in the Beacons for use in the association process.

Client stations broadcast Probe Request frames on all supported channels in the regulatory domain. Nearby access points respond with Probe Response frames. Client stations record information in the Probe Response frames for use in the association process.

Client stations broadcast Probe Request frames on the single channel for which they are programmed. Nearby access points respond on that channel with Probe Response frames. Client stations record information found in the Probe Response frames for use in the association process.

Access points broadcast Beacons on a single channel for which they are programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.

NEW QUESTION 93
The requirements for a WLAN you are installing state that it must support unidirectional delays of less than
150 ms and the signal strength at all receivers can be no lower than -67 dBm. What application is likely used that demands these requirements?

VoIP

E-Mail

FTP

RTLS

NEW QUESTION 94
A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11ac AP. Both the client and AP are 2×2:2 devices. What is the likely cause of the low data rate issue?

Weak signal strength

CAT5e cabling run to the AP

Too few spatial streams

Lack of support for 802.11n

Explanation/Reference:

NEW QUESTION 95
What item is essential for performing a manual RF site survey for a warehouse facility?

Predictive site survey software that supports highly directional antennas

NEW QUESTION 96
An IEEE 802.11 amendment is in the draft state. What impact does this draft amendment have on the 802.11 standard?

No impact: Until an amendment is ratified, it does not become part of the standard.

Devices will be released based on the draft amendment and the draft amendment features are part of the standard.

The standard is changed to reflect the new capabilities as soon as amendment enters the draft stage.

No impact: Draft amendments do not become part of the standard until a working group is formed.
