Across
- 1. passing many packets before frame acknowledgment is required
- 3. increases the speed over FDMA by dividing the channels into time slots and assigning slots to calls. Prevents eaves-dropping in calls
- 10. the unique 32-character identified that represents a particular wireless network and defines the basic service set
- 11. the easiest way to install wireless 802.11 devices which can also communicate directly without the need for an access point.
- 12. standard that is very high-speed, short-range wireless technology
- 14. one of the techniques used in celluar wireless networks. It divides the frequency range into bands and assigns a band to each subscriber.
- 15. how antennas are rated in units
- 17. wireless equipment has the ability to operate in what’s known as infrastructure mode
- 19. all access points are set to the same service set identifier (SSID), mobile clients can roam around freely within the same network.
- 21. the most widely used wireless network found today
- 22. the controller and access point (AP) split duties
- 23. two-way forms of communications using the same frequency to both transmit and receive.
- 24. monitors a device’s operating range for any radar signals that are allowed to operate in portions of the 5 Ghz as well as 802.11a before transmitting.
- 25. sending several frames by several antennas to optimize throughput and multipath resistance
- 26. setting client machine’s adapter and the access point’s transmit power to cover various size ranges
- 27. decreases the amount of overwhelming public IP addresses
Down
- 2. 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
- 4. the introduction of all sorts of devices to the network (and Internet) that were not formally there.
- 5. point to multipoint antenna
- 6. 802.11n/up to eight antennas
- 7. a component that connects all wireless devices together
- 8. distance, walls and other barriers, protocols used, and interference can all cause…
- 9. point-to-point antennas which usually provide greater range.
- 13. both enabled NIC cards are set up to operate in an ad hoc mode.
- 16. the connection from the access point to the wired network
- 18. a type of cellphone that contains a Subscriber Identity Module chip and must be present in the phone for it to function.
- 20. controls multiple transmitters and receiver antennas to increase data throughput
