High Bandwidth Wireless Networking Technology Comparisonune
D'après Pulse-Link

First Generation Pulse~LINK™ UWB technology will create a new market niche in performance.

A crowded field of competitive technologies exists for wireless networking technology with transmission distances under 300 feet.

None of the prevalent technologies currently on the drawing boards offers high bandwidth wireless networking outside of this circle.

Pulse~LINK™ is being engineered to outperform from its earliest generations.
