Whooops! Changes we wish we had made before the book went out

Hey, nobody is perfect, so there are some things in each book that were inserted by the copy editors (:-)) Also, changes happen from time to time that we need to update here. This is organized by chapter to make it an easy reference for you. If you see something we should change, !

• We mention the term Wi-Fi5 in here. This was the term du jour when we were writing the book, as the wireless industry tried to define the differences between 802.11b, g. and a. It's dead now, it did not take off. Now the terminology has changed. The terms surrounding wireless networking can get complex. First off, the order of lettering is not really right, since 802.11b was approved and hit the market before 802.11a. Also, you’ll see the term Wi-Fi used a lot. Wi-Fi refers to the collective group of 802.11 specifications, 802.11a, b, and g. You may sometimes see this group also called 802.11x networking, where x can equal a, b, or g. To make matters more confusing, there is a higher level parent standard called 802.11 that predates 802.11a, b, and g, and is also used to talk about the group of the three standards. Technically, it’s a standards group over several other emerging specifications as well. You can use 802.11 and Wi-Fi synonymously to talk about the three standards as a group. (We could use 802.11x, but we just wanted to save a lot of x’s (for our wives).)
• On page 80, we said that Dish and DirecTV were looking at a merger -- this has been called off, and they are still two independent sources for satellite coverage. Since then a new player, VOOM (www.voom.com), has also come out, focusing just on HDTV content.

• On page 241, there is mention of the HomeRF group, and how it is basically dead. Well, now it is officially dead, as the HomeRF standards-setting organization has disbanded. Don't fall for cheap deals on Ebay. Go with the 802.11x standards instead. You'll be happy you did.
