1. Omnidirectional

2. In wireless networking - the process that describes a station moving between BSSs without losing connectivity.

3. A destination node must issue an acknowledgment for every packet that is received intact.

4. A method of satellite Internet access in which a subscriber receives data via a satellite downlink transmission - but sends data to the satellite via an analog modem (dial-up) connections.

5. This type of propagation uses the least amount of energy and results in the reception of the clearest possible signal.

6. What frequency band is used by Bluetooth - 802.11b - and 802.11g?

7. In the context of wireless networking - an assessment of client requirements - facility characteristics - and coverage areas to determine an access point arrangement that will ensure reliable wireless connectivity within a given area.

8. In the context of wireless networking - the process in which a station listens to several channels within a frequency range for a beacon issued by an access point.

9. In the context of wireless networking - a frame issued by an access point to alert other nodes of its existence.

10. Because of reflection - diffraction - and scattering - wireless signals follow a number of different paths to their destination.

11. The use of multiple frequencies to transmit a signal. (because the signal is spread out over the wireless spectrum)

12. A method used by wireless stations to detect the presence of an access point. In _____ _____ - the station issues a probe to each channel in its frequency range and waits for the access point to respond.

13. In the context of wireless networking - the communication that occurs between a station and an access point to enable the station to connect to the network via that access point.

14. On your Linux workstation - you open a terminal window and type at the command prompt iwconfig eth0 key 5c00951b22. What have you done?

15. A type of WLAN in which stations communicate with an access point and not directly with each other.

16. In IEEE terminology - the identifier for a BSS (basic service set)

17. A group of access points and associated stations (or basic service sets) connected to the same LAN.

18. Used by newer types of WLANs. A range of frequencies that comprises four frequency bands: 5.1 - 5.3 - 5.4 - and 5.8GHz. It consists of 24 unlicensed bands - each 20 MHz wide. This band is used by WLANs that follow the 802.11a and 802.11n standards.

19. The term used to describe the recently released standards for high thoughput - long-distance digital data exchange over wireless connections. WiMAX (IEEE 802.16) is one example of a wireless broadband technology.

20. A. CSMA/CA

21. Which techniques help to reduce overhead in 802.11n wireless transmission?

22. The signals made of electromagnetic energy that travel through the atmosphere.

23. If your wireless stations are configured to perform passive scanning - what do they need from an access point to initiate association?

24. Networks that transmit signals through the atmosphere via radio frequency (RF) waves.

25. A unique character string used to identify an access point on an 802.11 network.
