Hi Jason,

 

Be aware of Class 1 bluetooth devices. They are capable of a range of 100m, but (unfortunately), paired with class 2 devices (like phones and PDAs) the range is still 10m. See for example http://www.palowireless.com/infotooth/knowbase/general/10.asp for more details.

P.S. The Mitsumi USB Bluetooth module is one of the smallest available on the market and is very stable using modified TDK Bluetooth drivers. See: http://www.mitsumi.de/index4.html. I buy it from here, in Romania with about 60EURO.

Hi Jason,

 

Bluetooth use a spread spectrum technology and less power, so you can use both. 802.11b work on a single frequency, so the interference must not be an issue.

I use both: bluetooth for sync with Ericsson T39 and Compaq iPaq H3870 and 802.11b for home wireless network. Unfortunately, the range of 802.11 in concrete buildings is a lot much smaller as expected. With a great difficulty I can cover the full flat. The range of Bluetooth (10m for small power class) is allmost the same as for 802.11 in concrete buildings, which is great. I use a Mitsumi USB Bluetooth Adapter with modified TDK drivers and it works great. More than that, on the same notebook I have the bluetooth adapter and the 802.11 card (Compaq WL110) and there is no interference problem. I can sync the iPaq and phone with the notebook and trough the 802.11b the notebook is connected to the Internet (trouugh AP), so I have for iPaq a bluetooth connection to the internet (no other interface required). It's cool.

 

BR,

Dan
