What method is used in an IEEE 802.11 WLAN to configure a QoS AP to deliver queued frames to a QoS STA during
What method is used in an IEEE 802.11 WLAN to configure a QoS AP to deliver queued frames to a QoS STA during an unscheduled service period?
What procedure is performed by a WLAN controller in order to optimize access point power and channel assignmen
What procedure is performed by a WLAN controller in order to optimize access point power and channel assignments based on the RF environment?
When may QoS STAs and QoS APs decrement their randomly chosen Backoff Time?
Given: While using the EDCA access mechanism, QoS STAs and QoS APs must use a backoff algorithm in order to arbitrate for medium access. The backoff procedure includes randomly choosing an integer from the contention window.
When may QoS STAs and QoS APs decrement their randomly chosen Backoff Time?
whatever channel the HR-DSSS radio is using?
XYZ Company is using a single ERP access point in their New York branch office. There are ten ERP wireless client stations currently on the network, each in use by XYZ’s full-time employees. XYZ has hired a consultant to work on some accounting problems, and he is using an HR-DSSS radio card in his laptop. How might this affect XYZ’s WLAN throughput capacity on whatever channel the HR-DSSS radio is using?
Which statements regarding an IEEE 802.11 Channel Switch Announcement frame are true?
Which statements regarding an IEEE 802.11 Channel Switch Announcement frame are true?
Which statement is accurate concerning the access point’s responsibilities in the Basic Service Set?
An ERP access point has both ERP and HR-DSSS stations associated and transmitting data. Which statement is accurate concerning the access point’s responsibilities in the Basic Service Set?
Which statement is true regarding use of these two protection mechanisms?
The IEEE 802.11 standard (as amended) specifies two protection mechanisms: RTS/CTS and CTS-to-Self. Which statement is true regarding use of these two protection mechanisms?
where would you look to view the WEP Initialization Vector (IV) information?
While analyzing a small office wireless network, you notice WEP is in use. In your protocol analyzer, where would you look to view the WEP Initialization Vector (IV) information?
Which event will the protocol analyzer allow you to see that you would likely not see without it?
As a consultant for XYZ Company, you have been asked to go to a customer site to troubleshoot a problem with intermittently slow throughput on an indoor ERP WLAN. You take your dual-band 2.4 GHz (ERP) / 5 GHz (OFDM) IEEE 802.11 protocol analyzer along as a troubleshooting tool. Which event will the protocol analyzer allow you to see that you would likely not see without it?
what makes co-channel IEEE 802.11 transmissions more detrimental than random RF noise in some cases?
When site surveying for an IEEE 802.11 network that will carry both voice and data traffic, what makes co-channel IEEE 802.11 transmissions more detrimental than random RF noise in some cases?
