ABC Company is having VoWiFi latency problems on their 802.11g WLAN. A wireless administrator has noticed in the phone’s client utilities software that the MAC CRC Error count is higher on stations with problems than on those client stations without…
What MAC layer information will a dual-band 802.11n protocol analyzer capture if it is capturing data frames encrypted with WPA2-Enterprise? (Choose 2) A. Source IP Address B. Null Data frames C. TCP SYN datagram D. Short Interframe Spaces E. Sequence…
As shown in the exhibit, a spectrum analyzer has measured both 802.11 and non-802.11 RF transmissions in the 2.4 GHz band. The exhibit shows a continuous video transmitter near channel 5. Based upon the exhibit, what impact does the video…
As it relates to a spectrum analyzer, complete the following sentence. The ____________ plot always displays the percentage of time (shown on the Y axis) that the overall RF power is a certain specified threshold (of amplitude) above the noise…
Given: Before installing a Wi-Fi network, ABC Company performed a spectrum analysis looking for problems. The 2.4 GHz RF spectrum looked like Image-A. After installing an ERP WLAN, ABC Company performed another spectrum analysis during business hours. The 2.4 GHz…
Using the exhibit as a reference, which spectrum plots display, in real time, the value of RF amplitude as a function of radio frequency? A. 1 and 2 B. 1 and 3 C. All of the plots D. 1, 3,…
Given: The graphic is taken from a spectrum analyzer. What types of RF transmitters are illustrated? A. An IEEE 802.11 HR/DSSS security camera on channel 6 and an RFID tag B. A Bluetooth headset and a narrowband RF jamming device…
What types of wireless systems are illustrated? A. An ERP IEEE 802.11 system using channel 6 and Bluetooth v1.2 discovery B. A Bluetooth v2.0 file transfer and a 40 MHz HT AP on channels 11, 7 (primary, secondary) C. A…
Given: ABC Company recorded the 2.4 GHz band with a spectrum analyzer prior to installing their ERP WLAN. Image-A is how the band appeared prior to the WLAN installation. Image-B is how the band appears now, and all channels on…
Given: The exhibit shows a small network environment with dual-band APs. What is true of the network shown in this spectrum analyzer trace? A. There are at least three APs operating in this environment. They are operating on channels 149,…
