1 13 Text correction: Incorrect data rates in WLAN standards 802.11a and 802.11g
There are two instances on page 13 in which the same error is included. The last two bullet points of the lists under 802.11a and 802.11g:

"6, 9, 12 Mbps OFDM required data rates
18, 24, 36, 48, and 54 Mbps OFDM data rates are supported but not required" are incorrect.
They should read:
"6, 12, and 24 Mbps OFDM required data rates
9, 18, 36, 48, and 54 Mbps OFDM data rates are supported but not required"

2 48 Correction to Figure 2.16: Standard Ethernet pin assignment
The figure is incompletely and incorrectly labeled.
The leftmost pair, identified as Pair 3, should be labeled "Pair 2 Orange".
The topmost label, Pair 2, should be "Pair 3 Green".
The center pair, Pair 1, is correctly labeled Pair 1, but should also be identified as Blue.
The rightmost pair, Pair 4, is also correct, but should be identified as Brown.

The figure illustrates the EIA/TIA 568B standard.

A downloadable version of the corrected image is available on the Resources and Downloads tab.

6 172 Text correction: Incorrect horizontal beamwidth given for patch/panel antennas
The third sentence under "Patch/Panel Antennas":
"A patch/panel antenna can have a horizontal beamwidth of as high as 180, but usually the horizontal beamwith is between 50 and 80." contains inaccuracies. It should read:

"A patch/panel antenna can have a horizontal beamwidth of as high as 180, but usually the horizontal beamwith is between 35 and 60."
Additionally, add a sentence following that one that reads:

"The vertical beamwidth usually ranges between 30 and 80"

158: To be more consistent with the supporting text in the book, the question should refer to radio-chains, not "radios".

216: Answer given is a duplicate of the answer to 217. The correct answer is "An existing wireless network is a potential source of interference."

220: Question is ambiguous. Change the question to read "What length of RF cable will cause loss in a wireless LAN system?" Change the answer to read "An RF cable of any length will cause some loss in a WLAN system."
