It's a deafening sound: Bluetooth and wireless Ethernet rush into a noisy head-on collision

Choice No. 2. Decide there is a problem and integrate either Mobilian's solution or a similar solution into their products.

Choice No. 3. Offer some devices at one price without a solution that mitigates the interference and then offer at a higher price a luxury version that works all the time.

Does this have the potential to turn into a real problem for providers and customers?

Scenario No. 1. MobileStar just signed a deal with Starbucks and Microsoft to put wLAN access points in all 2,200 Starbucks coffee shops. The access points connect to servers connected to the Internet. A year down the road you might find yourself in Starbucks with your new company-issued Toshiba with wLAN and Bluetooth built in. So what's the problem?

"Bluetooth will kill the signal," says Ron Nevo, director of engineering at Hillsboro, Ore.-based Mobilian.

Scenario No. 2. Wayport is doing the same thing as MobileStar but at airports.

Yes, 802.11a, the next version of wireless Ethernet, will move to the 5GHz band, but in the meantime, Intersil is currently shipping about 1 million 802.11b chips each month. I think 802.11b will be around for a while.

Remember that the higher the frequency -- in this case 5GHz -- the more problems it has going through walls and people.
