The maximum aggregate capacity for an 802.11 DSSS system in a co-located environment is?

  1. 2 Mbps
  2. 6 Mbps
  3. 22 Mbps
  4. 24 Mbps

Answer(s): B

Explanation:

This question is slightly confusing.However, if read closely, it states that the system is in a "co-located" environment. From our previous discussion, since DSSS systems support a maximum of 3 APs in a co-located environment and given that the 802.11 standard allows speeds upto 2 Mbps, therefore, that would make the answer 2(x3) = 6Mpbs. Therefore, the answer should be B.



After August 31, 2000, the FCC mandated that FHSS systems using fewer than 75 hops must have a maximum power output of?

  1. 100mW
  2. 125mW
  3. 500MW
  4. 1W

Answer(s): B

Explanation:

- a part of the 802.15 standard for WPANs (Wireless Personal Area Networks). Bluetooth is a close-range networking protocol primarily used for mobile devices, utilizing FHSS in the 2.4 GHz ISM band at around 1600 hops/second. Because of the high hop rate, Bluetooth devices will greatly interfere with other devices operating in the 2.4 GHz band.



Which of the following us TRUE when using Bluetooth in an 802.11b environment?

  1. Interference can be avoided by selecting different DSSS sub-channels
  2. Interference can be avoided by allowing Bluetooth to use a proprietary hopping pattern.
  3. Interference increases as distance between the two systems decreases.
  4. Bluetooth does not interfere with DSSS.

Answer(s): C

Explanation:

Less than 75 hops enforces the Post August 31, 2000 rule for FHSS systems in which max. power is 125 mW and max. carrier frequency is 5 Mhz (See page 73 of the CWNA study Guide (2nd edition))



Before going into a low-power state (sleep), what function must a wireless station operating in a BSS perform?

  1. Notify the access point of its intention to sleep.
  2. Notify other wireless stations of its intention to sleep.
  3. Broadcast an ATIM on the network.
  4. Send an RTS to the access point.

Answer(s): A

Explanation:

Traffic Indication Map (TIM) - transmitted by the access point to indicate to sleeping stations the presence of buffered transmissions for a particular station Traffic Indication Map (TIM)
The TIM is used an as indicator of which sleeping stations have packets queued at the access point. This information is passed in each beacon to all associated stations. While sleeping, synchronized stations power up their receivers, listen for the beacon, check the TIM to see if they are listed, then, if they are not listed, they power down their receivers and continue sleeping.



Which of the following are features included in the 802.11 standard? (Choose all that apply)

  1. Support of asynchronous and time-bounded delivery service.
  2. Use of the CSMA/CD and RTS/CTS protocols.
  3. 802.1x with EAP support.
  4. Wireless VPN tunnels with RADIUS authentication methods.

Answer(s): A

Explanation:

Point-to-Point Protocol (PPP) - A protocol that provides router-to-router and host-tonetwork connections over both synchronous and asynchronous circuits. PPP is the successor to SLIP.An IEEE 802.11 mode that enables contention-free frame transfer based on a priority mechanism; stations are polled for the need for frame transmission. Enables time-bounded services that support the transmission of voice and video
