A Seattle-based company, TeraBeam Networks (www.terabeam.com), claims to have found a way to achieve optical fiber speeds without cable, using light waves to carry the data. The company is aiming its "fiberless optical" networks at metropolitan areas, with transceivers on customers' premises exchanging data with TeraBeam devices installed around a city-a pattern similar to mobile telephone's overlapping cells. The wireless technology promises bandwidth of several gigabits per second, but requires a clear line of sight between each data note. TeraBeam hopes the service will be deployed this summer, with goals of covering the top 50 U.S. cities and several international cities within three years.
