Is wireless data ready for prime time?

The network has been cleverly designed and built-out. On the user end, it starts with rugged, easy-to-install wireless modems that work with a variety of PC, Macintosh and handheld devices. These modems acquire signals from microcell radios: shoebox-sized intelligent transceiveers usually mounted to streetlights or utility poles in a mesh network. These microcell radios communicate with users' laptops or handhelds through the wireless modems and are configured to route incoming packets to the optimal Wired Access Point. (Every packet sent contains a compressed summary of the data that ensures reliability.)

These Wired Access Points, strategically placed, collect and convert the radio frequency packets into a format for transmission on a local wired IP network. One critical component of the Wired Access Point is its Ethernet radio, which operates like a microcell radio but converts radio data packets into a format transmittable to a wired IP network. This key RF-to-IP translation is the linchpin of the WorldCom system; it takes advantage of the faster speeds inherent in such technologies as

fiber-optics and T1.

All Wired Access Points in a region are linked to a regional Network Interface Facility, which in turn connects the wired network to one of WorldCom's Network Operations Centers.

Available in some major markets in early 2001, WorldCom's Wireless Internet is expanding at a breakneck pace; coverage will reach 100 million people by late 2001.
