Bluetooth's dominence in the low power sector of the market means when it is running as a class 2/3 device at 4dBm or 0dBm which covers adequate distance of 10m it does not guzzle your power in your mobile device this is why it is prefered to 802.11b. Now the question that poses is well since we are going to slap it in our mobile systems should we start to look at it's viability as a WLAN..... I think no! It serves well for ftp and sync work and even cable replacement but I fear by splitting the stack into a services orientated thing it seems to have taken away the simplicity it was originally intended to bring with it. I think technical knowledge needs to improve around this standard and the realisation that if you want to research into it it's very time consuming (opensource project 18mnths with experts in different fields. My concern is OK when we operate Bluetooth /802.11b side by side they don't seem to impact to much. That is Bluetooth on 802.11b because of it's ruthless way over 802.11b's curtious approach sniff first, but reality says when Bluetooth floods the market and now we are talking scatternets the more spectral density these collisions are going to occur more frequent and boy when you take your phone and laptop into work along with every one else in the coorporation you could end up grinding the system to a halt. 802.15 TG2 have come up with avoidance techniques for these technologies to employ and I think this will be the way forward....
