Printed | Page 18 Figure 3-2 |
In Figure 3-2, the upper part of the diagram shows an 802.11n channel ranging from carrier -26 to +26. It should be -28 to +28 (as shown, in fact, in Figure 3-1). |

Printed, PDF | Page 20 On page 20; for Figure 3-3. |
On page 20; for Figure 3-3. Available channel map (5 GHz). The right side column of 5 GHz channel numbers are all wrong, that should be channels 149, 153, 157, 161, and 165. In addition, the center channel column, I do not think the USA can use channel 144, looking at the 5 GHz channel maps and articles I can find online none of them seem to say that any country can use channel 144. I think this should stop at channel 140 and 5710 MHz. Note from the Author or Editor: |
