Site surveying has finally standardized. The process is well-understood among industry professionals - though not always implemented properly. Just when we thought we had it whipped, we get a curve ball: mesh. Have you checked out systems from vendors like Ruckus, Motorola, Meru, Cisco, and Aruba that have the option to have mesh APs connecting back to root APs? This is a seriously nice feature, but have you thought about doing a manual survey for such an implementation? Let's explore that, shall we? |

I've been having an interesting discussion with an instructor regarding the term "adjacent channel", and I would like to solicit comments from our constituents regarding this term. In the 2.4 GHz band, channels 1 and 2 are considered "overlapping" by the 802.11 standard, but the question is, "are they adjacent?" According to the standard, they are not. The instructor - a very expererienced one - argues that the most common use of the term "adjacent channel" has it meaning "directly next to" rather than defining it by a given frequency distance. For example, the standard defines channels 1 and 6 in an 802.11g system as adjacent because they are separated by at least 25 MHz. The reason this terminology is so important is because the term "adjacent channel" carries over into "adjacent channel interference." The defining of what adjacent channel interference *is* and *is not* is important. |

After many years of networking, one thing I can do in my sleep is load a Windows driver. That's a pretty good thing considering that working in networking means constantly loading and changing NIC drivers - wired and wireless.
Linux desktops are getting remarkably easy to use, Ubuntu being my personal favorite at the moment. Novell, Redhat, and Xandros all make some butt-kicking stuff as well. These Linux desktop operating systems have almost everything known to man built right in, and they are so much like Windows that, with the right skin, they would be almost indistinguishable from Windows itself. I think that rocks. They are easy to install and use, and best of all, they are either cheap or free - my personal favorite being free. |
