When it comes to wireless, sometimes it's difficult to separate fact from fiction. There are certain adages or rules that many feel are a given. But that may not always be the case.

With that in mind, we've assembled this list of eight common misconceptions about wireless.


  1. The more height the better - This is not necessarily right. It depends on a few things, the first being the antennae. For yagi and dish antennas the height of the antennae will mean something different from omni antennas.

  2. The more gain the better - Actually, higher gain can be a double-edged sword. Sure, more gain provides more signal strength within the coverage area, but at what cost? Depending on your environment, you may not be doing yourself any favors. In fact, you might be doing the opposite.

  3. Diversity means I can cover 2 rooms with 1 AP - Not so fast, my friend! This is not the case. It's not a matter of extending coverage of a radio cell. It's about enhancing it. So, do not go for this misconception. You should really look into this more to understand these concepts fully.

  4. Wireless signals won't go through trees - This is not entirely true. People fall on either one side or the other. However, this is not a clear-cut answer. A signal can go through a tree, but there are varying rates of signal loss. Knowing your environment is important. You should do more homework and find out more about the losses incurred and understand how trees affect your signal.

  5. Wireless G gives me 54mb - Not really. In practice it is much less. There are some real-life variables that account for this. The point is that you want the real-world, in-practice number and not the theoretical number.

  6. I need wireless AC! - Why? It's new. It's shiny. It's fun. It's super cool. Well, you might be surprised by what people think is super cool. Before you make the jump here, again, you should learn more about what this really does for you given your specific needs and environment. You may be surprised to learn you may not need wireless AC, after all.

  7. Wireless networks need external security, right? - Nope. There are both internal and external security options provided by most vendors.

  8. LAPs need to be directly connected to the controller - They don't. There is a wealth of information here and you may be able to save some money if you get all of the facts and act accordingly.

As you can see, there are plenty of misconceptions out there about wireless networks.
