Pulse~LINK Shows 667 Mbps Wireless UWB

Pulse~LINK, a start-up based near San Diego, demonstrated 667 Mbps data rates transmitted and received over an Ultra Wideband (UWB) wireless connection using forward error correction. The company said its new high-speed chipset architecture is capable of surpassing one Gigabit rates.

"Our actual over-the-air data rate is at present 1.3 Gbps per second, with the data throughput presently at 667Mbps," states John Santhoff, Founder and CTO. "Over the next thirty to sixty days, optimization will bring the throughput to Gigabit data rates."

Pulse~LINK plans to launch Gigabit wireless UWB evaluation kits to partners in February 2005. The company's Gigabit RFIC is presently in fabrication and evaluation kits based on the sample RFIC are planned for release in April 2005. In addition to its high speed UWB technology, Pulse~LINK is introducing a new forward error correction technology for wireless communications that it claims is far more efficient at extremely high data rates than the Viterbi forward error correction technology commonly used in other wireless communications.

Pulse~LINK said applications for its chipset could include wireless solutions for DVI (Digital Visual Interface), HDMI (High Definition Multimedia Interface) and 1394b (Firewire) cabled devices.

Along with providing higher data rate solutions, Pulse~LINK is developing longer-range UWB transmissions for Wireless LANs. In recent demonstrations, Pulse~LINK transmitted two simultaneous HDTV signals for "picture-in-picture" television through a combined seven inch thick concrete wall and an additional steel-frame drywall at ten meters and has demonstrated the same two streams at distances of 25 meters through one steel-frame drywall.
