This is likely to start an IT geeky discussion but its worth mentioning. This brings up my very first concern on this band. My concern was that there are literally hundreds of gain boosting products on the market for 2.4 Wimax technology. Many of these devices such as home routers and small to large business line of sigh WiMax shots get "amped" up by the IT department. I know I found a 10X gain booster for my home system. Now considering that most of these routers have their own range of channels and can switch between dedicated channels to a mode that basically hops channels until things hook up you can begin to see the challenge in this unregulated band in areas of high population.
Luckily most of the units have a 150 foot range but with a major gain booster that could go up to 1000 feet. I improved mine enough to setup a WIDE area network between my house and my neighbors house about 900 feet away. I can get a small boost using a 2.4 aircard in a laptop and a pringles can....the technology is out there and the freq is unregulated. Consider the carnage potential at the next major event when some Frankenstein WIMAX WIFI solution fires up... not currently a challenge with multiple Chanel acquisition but without regulation how long will it be until something is created that flies through the channels in order to create better security for the ever increasing IT security threats? 900MhZ phones had that in the 90's and Sanyo is touting DSS at 2.4 as well. Its slightly different technology but my concern is that its simply not regulated. So while I will still move to 2.4 next year I will be paying close attention to this band.
