Which four options are the characteristics of the original 802.11 protocol? (Choose four.)
A. Defined DSSS and FHSS as possible methods for modulation
B. Designed to operate in the 5 GHz ISM frequency spectrum
C. The most common deployment is three non-overlapping channels that are 20 MHz wide
D. The protocol sets the maximum throughput at 1 Mb/s or 2 Mb/s
E. Defined FHSS and OFDM as possible methods for modulation
F. The most common deployment is three non-overlapping channels that are 22 MHz wide
G. Designed to operate in the 2.4 GHz ISM frequency spectrum
H. The protocol sets the maximum throughput at 1 Mb/s
The network administrator receives complaints of slow wireless network performance and performs a sniffer trace of the wireless network in preparation for migration to 802.11n. The sample capture shows frames that contains AP beacons with NonERP_Present bit set to 1 and frames with RTS/CTS.
Which two conclusions can be interpreted from these frames? (Choose two.)
A. The network is performing slowly because 802.11n clients are already mixed with 802.11g clients.
B. The network is performing slowly because 802.11b clients still exist in the network.
C. The network is performing slowly because a wireless client is incorrectly configured, which results in RF interference.
D. Possible 802.11b wireless clients are located only in the AP cell radius where the sniffer capture was performed.
E. Possible 802.11b wireless clients could be located anywhere in the wireless network.
How many dBm is 40 mW?
A. 10 dBm
B. 16 dBm
C. 20 dBm
D. 22 dBm
E. 40 dBm
If an antenna has a dBd of 8.6, what is the dBi value?
Which calculation computes the EIRP of an antenna?
A. EIRP = Tx power (dBm) + Antenna Gain (dBi) – Cable Loss (dB)
B. EIRP= Cable Loss (dB)+ Antenna Gain (dBi) – Tx power (dBm)
C. EIRP = Cable Loss (dB)+ Antenna Gain (dBi) / Tx power (dBm)
D. EIRP = Tx power (dBm) + Antenna Gain (dBi) / Cable Loss (dB)
E. EIRP = Antenna Gain (dBi) – Cable Loss (dB) * Tx power (dBm)
F. EIRP = Tx power (dBm) * Antenna Gain (dBi) / Cable Loss (dB)
