1. Wavelength=speed of light(constant)/Frequency.

2. The distance between similar points on two back-to-back waves. Typically measured from the peak of a wave to the peak of the next wave

3. The relationship between two waves with the same frequency

4. Is an alternating current (AC)that continuously chaanges b/wa possitive and negative voltage.

5. Developed Open Systems Interconnection (OSI) model

6. Non-profit group devoted to the growth of wireless LANs (WLANs). One of their primary task is to ensure interoperability of WLAN products by providing certification testing

7. The fluctuation of voltagein an AC current - AKA Cycling. Single change from up to down -or from positive to negative to positive.

8. The distance that a single cycle RF wave travels.

9. Height - force - or power of a wave

10. The manipulation of a signal so that the receiving station has a way of distinguishing 0s and 1s

11. Global hierarchy that maintains a database for worldwide frequency assignments and coordinates spectrum management through five administrative regions

12. A current state technique. one frequency can represent a 0 bit and another frequency can represent a 1 bit

13. Range of all possible electromagnetic radiation

14. Independent United States agency that regulates communications to and from the United States. Regulates radio signals that are used for wireless networking

15. Varies the phase of the signal to represent the binary data. State transition technique. determines the data that is being transmitted. one phase can represent a 0 bit and another phase can represent a 1 bit

16. The speed of an RF signal in a vaccum

17. A term describing a behavior of waves. How fast the waves travel - or more specifically - how many waves are generated over a 1-second period of time

18. Shape and form of the AC signal

19. Effective area for receiving power (catching signals)

20. Varies the height of a signal to represent binary data. A current state technique.

21. A modulated signal that is capable of distinguishing between 0s and 1s

22. In terms of CWNA it means the loss of signal strength.
