RE: BT APs for a very small purpose?
I was previously unaware that accessing a class 3 (30 meter range) BT wireless access point would consume more power than if you were using a class 2 BT WAP.

RE: BT APs for a very small purpose?
I'll put it another way. If you have a laptop, you probably have 802.11 hardware built in or added on. Fine. You might have a BT dongle for connecting to your phone for access when you're away from an 802.11 access point. Fine. Given the choice, you'd use an 802.11 access point at home, not a BT one which I believe most people would agree with.
Let's say you have a PDA. It has 802.11. Fine, get an access point for it to work at home, and forgo connectivity on the road.
Now let's say your PDA has BT. You have connectivity on the road with a BT phone. At home or in the office, you use a BT access point. But is it worth it? After all, the BT transmitters in PDA's are very low power - class 3. That's 30 feet max, at optimal (no walls) environments. You would basically have to stand around the access point, or at least relatively close. It doesn't matter how powerful the access point is - the PDA BT device is the limiting factor.
So what you basically have is a BT access point that only works in a small area. I have a class 1 device (300 feet effective) but when it communicated with any BT PDA I have (or my roommate's), it can barely make it 15 feet thanks to the low powered BT in the PDAs. Your options are to either sit in a spot near where you place the access point, or place more than one around your home/apartment if you move around.
If these access points were cheap (say, $20 a pop), it might be ok, but I have a feeling that they will be in the $100 and up range when they first start selling.
That's quite expensive for an access point which will in all likelihood only be servicing your PDA in a very limited area, don't you think? Especially when you can get decent USB class 1 BT dongles (the Belkin's are excellent) for your PC for $25 and basically get the same thing...?
These access points are nice, but it all comes down to this:
What will they interface with? Laptops? Possibly, but 802.11 seems to be a better solution in that regard. PCs? I guess, though even 802.11 has more bandwidth than BT's max of around 1mbps, making it a very slow networking solution. That leaves PDAs and... what else?

"....Bluetooth access points present a very attractive alternative to Wi-Fi for many applications that value security and low power consumption. I strongly urge you to consider evaluating this technology very carefully before blindly jumping on the Wi-Fi bandwagon… especially if that bandwagon runs on batteries."
http://www.planetpdamag.com/content/052202rt.htm
There have been many debates as to which is the ultimate wireless technology that will prevail, and I fully subscribe to the suggestion that Bluetooth is a wire replacement technology, whereas 802.11b is more suitable for network connectivity. However, in certain environments, Bluetooth can be an attractive option for setting up a network.

802.11 is still prefered in most environments imho.

Bluetooth Power/Range Classes 1, 2 & 3
Power Class 1: is designed for long range (~100m/330
feet) devices, with a max output power of 20 dBm,
Power Class 2: for ordinary range devices (~10m/33 feet) devices, with a max output power of 4 dBm,
Power Class 3: for short range devices (~10cm/3.3feet) devices, with a max output power of 0 dBm.

RE: BT APs for a very small purpose?
Bluetooth will never replace 802.11 because they are fundamentally different and serve different purposes. BT's bandwidth is pitiful in comparison, but for what it does, there doesn't really need to be much more. Possibly in the future, a successor to BT or 802.11 will integrate BTs low power requirements with 802.11s range, but until then, I find it annoying to try and adapt BT applications to ones better suited bt 802.11.
However, with Impartial's quick reply, it looks like BT access points *can* be viable product.
RE: BT APs for a very small purpose?
Why doesn't someone create some sort of battery powered unit that one one hand connects to your PDA via bluetooth, and links you to your 802.11 wireless network on the other side. Take along something the size of a pack of cigarettes to "boost" your power.
If they are coming out with a 802.11 SD card, such a unit could be loaded up with battery storage.
Would something like this be compatible between the two wireless protocols?
Just a thought...

BT access point connects to what?
My home network uses a Linux-powered server with cable modem. From there, a router leads to a couple of desktops, one running Linux and another Windows.
I assume most BT access points will only connect to Windows initially, so can I hang the thing off the Windows desktop and still have it work?
Same question about 802.11b access points.
Thanks!

BT APs for a very small purpose?
I think BT access points are an ok idea (if they come down in price), but will the main uses be only for PDAs and such?
Because 802.11a/b/g is better for laptops and PCs where battery life is not such a concern as on a PDA, not to mention better coverage and bandwidth. For something like a Tungsten or IPaq to use the access point, it was to be closer than 10 meters, since they are almost always Class 3 devices (use a lot less battery power). The access point may be able to "see" the PDA farther away, but the PDA won't have enough power to reach back to the access point. Even for a normal sized apartment, you'd need at least two for full coverage.
Someone point out the holes in my logic, because I'm sure there are some.
