As we all know (well, at least for the WLAN geeks), The 2.4GHz band offers 11 different channels, 1-11, with only three of them (1, 6 & 11) do not overlap and can be used, and carefully reused, without interference. 5 GHz offers more channels than the 2.4GHz, about 13 non-overlapping channels, but signal coverage is a compromise resulting in an increase required number of Access Points (AP) at deployment. Due to these restrictions some site survey as with WLAN VoIP, a precise site survey is a must. Thus, channel and channel reuse should be immensely considered and engineered to proper the extent of the WVoIP signal requirement. Not to mention the headaches, backaches, feetaches and sometimes tootaches as some of the side results of site surveying. May SSS ka ba? hehehe... heartaches?... well, that's a whole lota different blog... heheehe.
During the survey, we encountered a lot of dead end spots, meaning all three non-overlapping channels are already used at one point in the area and that channel reuse isn't possible. This gave us big headache and slows the site survey as we have to re-channel everything, or worst, re-site survey some points. Whew! What we did was, apply the repeater mode to extend the coverage of a single channel to avoid clashing with its co-channel. Well, it made sense for awhile, until I remembered that we are going to implement thin APs! ding! ding! ding! dinggggg! wrong again! after a confirmation with Cisco that thin APs do not!, and I repeat, do not support repeater mode on thin APs.... we were again left to our own thinking devices. Since an intelligent Cisco WLAN Controller is going to be implemented, its AUTO RF feature can be used to avoid and overcome dead end spots. Holy Mackanoly! then why are we going through all this double, triple and quadriple trouble. Unfortunately, we have to make sure the WLAN VoIP meet the requirement for signal coverage... Ok, fine...
So, as I was doing this taking-forever, pain-staking, channel-reuse-sensitive task, I started looking for ways to make it easier for the whole process to finish. Google directed my clicks to Extricom, the author of Interference-Free Architecture. And right after reading comprehension.... my head went ballistic from left to right. Holy Mackanoly! This is it! This is really is it! A solution intended for our dilemma and enigma... hehe... I can imagine one whole floor in one channel and no worries about precise site survey, channel reuse and co-channel interference. Just add a thin AP and a surefire hit Plug and Play.
But this techno remains to be tested and verified. And if it works as it says it is, I hope Cisco acquires this, as well. Just like it did with Aironet and Airespace. Hey! Mr. John Chambers!!! If you happen to crawl into my blog, here's something for you to BLOG YOUR MIND! Hehehe.. AS IF.....
