How some wireless connectivity options stack up
Passive security makes it more vulnerable to breaches; 300-foot distance limitation.
Metropolitan-area coverage, 20- to 30-mile line-of-sight reach, two to three miles for in-building coverage; built-in encryption, and quality of service.
Prestandard; expensive until it hits mass market.
Evolution Data Optimized (3G cellular)
Wide-area and international coverage; moderately priced.
May not be fast enough for some broadband applications.
Line of sight only; very expensive; scales poorly for workgroup applications.
Widely available and moderately priced.
Line of sight only; prone to signal fading from rain, clouds and foliage.
