The company, as of late last year, had completed alpha testing on the product, was planning betas for January and expected to make the product available in volume in the third quarter of 2001. We're going through metal and brick buildings. But other vendors say non-line of sight is a misnomer. W-OFDM is a modulation scheme that offers improved bandwidth and noise tolerance. Troy Trenchard, director of product marketing at Cisco, believes that, despite the commonly used phrase, there is no such thing as non-line of sight.

We have the first shipping OFDM system that can handle obstruction which is near non-line of sight. For its part, Malibu expects to make available for beta tests a non-line of sight product based on OFDM and operating in unlicensed spectrum. General availability of its first products is scheduled for July. Sumi of Malibu says OFDM schemes' practice of sending out multiple waves enables them to support non-line of sight. Sumi adds that Malibu's products will also support dynamic modulation, meaning the system can change modulation as needed.
