This document contains what appear to be errors in the Study Guides and their answers:
#9 in ch01.htm is apparently incorrect. The answer of 11Mbps is based on the assumption that WI-FI refers solely to IEEE 802.11b. Here are contradictory statements from http://www.webopedia.com/TERM/W/Wi_Fi.html
"Short for wireless fidelity and is meant to be used generically when referring of any type of 802.11 network, whether 802.11b, 802.11a, dual-band, etc. The term is promulgated by the Wi-Fi Alliance."
"Formerly, the term "Wi-Fi" was used only in place of the 2.4GHz 802.11b standard, in the same way that "Ethernet" is used in place of IEEE 802.3. The Alliance expanded the generic use of the term in an attempt to stop confusion about wireless LAN interoperability."
#17 in Ch01.htm is incorrect. Should read 10 meters instead of 10 feet.
#25 in ch02.htm is incorrect. The IEEE 802.11 standard outlines the use of both diffused infrared and radio waves. This question and its answer makes it seem that the standard outlines the use of diffused infrared only.
#20 in ch03.htm is prbably incorrect. The material on page 92 of the textbook is confusing. The answer given on the practice test matches the value of TPO discussed in the corresponding paragraph in the textbook. However, the maximum EIRP given in Table 3-4 is 40mW or 16dBm
