Wireless LANs

1. Spock had one of these from the Star Trek mirror universe -- in a WLAN context, it describes a counterfeit access point. What is it?

2. This term describes electromagnetic energy having a frequency higher than 1 gigahertz, corresponding to wavelength shorter than 30 centimeters. (Hint: it has a common use in many homes other than communications.) What is it?

3. HiperLAN is a set of WLAN communication standards that provide features and capabilities similar to those of the IEEE 802.11 standards. Where is it primarily used?

4. SWAN is a technology that incorporates a wireless LAN into a wired wide-area network (WAN). What does "SWAN" stand for?

a. Structured Wireless-Aware Network
b. Switching for Wired Area Network
c. Structured Wireless Area Network
d. Switched Wireless Area Network

5. MIMO is an antenna technology for wireless communications that features a single antenna at the source end and a single antenna at the destination end. True or false?

6. From what two terms is the word transponder derived?

7. Abbreviated as AP, this is the more formal name for a hot spot. What is it?

8. Fixed wireless devices are usually in fixed positions and derive their electrical power from the utility mains, rather than batteries. True or false?

9. A WASP is a wireless application service provider. What's a WISP?

10. This popular, unidirectional antenna is commonly used for communications at frequencies above 10 MHz. What is it?
