CHAPTER 12 TERMS CROSSWORD

6. assigns a unique code to each call or transmission and spreads the data across the spectrum, allowing a call to make use of all frequencies
7. how antennas are rated in units
8. setting client machine’s adapter and the access point’s transmit power to cover various size ranges
12. a component that connects all wireless devices together
18. controls multiple transmitters and receiver antennas to increase data throughput
21. all access points are set to the same service set identifier (SSID), mobile clients can roam around freely within the same network.
