29. © 2004 Flarion Technologies 29 Industry Test Reports  “Our tests of NXTL/Flarion in North Carolina showed vastly superior bandwidth and latency to what we obtained during earlier 1xEV-DO, 1xRTT, and EDGE trials”  “Our tests suggest the NXTL/Flarion performance is vastly superior to all currently available mobility wireless data technologies and faster than most DSL services. We were also impressed with the contiguous network coverage”  “We went into this trial with high expectations and they were met”  “…technology is once again playing an important role in carrier decision processes and we could be in the early stages of another arms race with bragging rights for the biggest bandwidth being claimed by more than one operator.  “The performance of the system in Raleigh is quite good and should encourage Nextel to expand the system to other markets”  “FLASH-OFDM – is the best performing technology of the bunch (vs DO) from a single user’s perspective if he/she wants mobile data in a WWAN – mobile or stationary”
