Because there are many cases where you would want to run both
Bluetooth and Wi-Fi at the same time. For example, a Bluetooth
headset running Skype over a Wi-Fi to the internet. What's not
obvious about the Blue802 and other methods is that there really are
two radios on a single card. What Blue802 and others add is a method
of synchronizing the frequency used by both the Bluetooth and Wi-Fi
sections. This made lots of sense in the bad old days of Bluetooth
1.1, which hopped over the entired band. However, the FCC, in its
infinite wisdome, conceeded that it might be a good thing to allow
Bluetooth to selectively hop rather than trash the entire band. So, a
rule change allowed AFH (adaptive frequency hopping) in Bluetooth 1.2,
which largely eliminated the interference problem. If the Wi-Fi
device uses Channel 1, the Bluetooth device will detect this and move
to the other end of the 2.4GHz band. No synchronization required. So,
in effect, Bluetooth 1.2 does 99% of what Blue802 was suppose to do.
It's kinda hard to sell a product that nobody needs or that can be
done cheaper with just protocol tweaking.
I expect the next generation of laptops to all have Bluetooth 1.2 or
2.0 built into the motherboard as a standard feature. The chip sets
are cheap enough and the technology is finally stable enough to be
considered almost "mature". That will allow the total elimination of
the 3.5mm microphone and earphone jacks, to be replaced by an
equivalent Bluetooth headset. Wireless will probably remain on a
MiniPCI card.
Meanwhile, I suggest you live with the under $20 Bluetooth USB
dongles, which work fairly well. I suggest you get one that does
Bluetooth 2.0 as multimedia and stereo music via Bluetooth is sure to
be a big thing. Avoid anything that reeks of Bluetooth 1.1.
Incidentally, I've been tinkering with quite a few assorted Bluetooth
headsets and devices. In the past, I had severe mutual interference
between Bluetooth 1.1 and Wi-Fi. With Bluetooth 1.2 and 2.0, I can
still see some minor effects, but the garbage audio and loss of Wi-Fi
thruput are mostly gone.
