The next time you’re at Crossroads
Mall in Bellevue, near Microsoft’s main campus, take your laptop with a
wireless LAN card and get connected—not just to a wireless network—but
also to Microsoft Research’s grander vision of using next-generation
technology to communicate and compute in public places.
Plus, users can get a nifty shopping experience.
Thanks to the Systems and Networking group in Microsoft
Research (MSR), the CROWN (Crossroads Wireless Network) project—based on
wireless LAN technology called Choice—has been successfully deployed at
Crossroads. MSR’s Choice offers high-speed Internet access and location
services in public places. Because of the cooperative
efforts between MSR and the Advanced Strategies group, customers at
Crossroads can switch on and log on. Choice advertises itself through
beacon signals and picks up Internet-address requests that are sent while
booting. It returns a signal giving a short-term address to the computer.
When users are finished booting, they go to https://choice/ and log on to MS
Passport for authentication. A temporary soft "key" is sent to the
computer so that it can use the wireless services at Crossroads.
At the moment, users can get e-mail and Internet access
through the CROWN project at Crossroads, but Choice technology offers many
other options. For example, Choice can use the MSN Messenger
Buddy list to determine if a user has friends online and within the given
area of the Choice network. So, if Buddy_01 is at a store at the other end
of the mall or the airport, Choice will send an alert to the user with a
map showing Buddy_01’s location. Vendors can also opt to use
the OnSale feature of Choice that enables them to send sale details—for
instance, if a Compaq iPAQ is 20 percent off for 30 minutes—to the Choice
network. The network instantly would search user profiles to find out if
they have Electronics listed as items they are interested in purchasing.
If so, the OnSale message will appear as an Instant Message Alert on the
user’s screen. For more information, go to http://choice/ or
http://www.mschoice.com/.
