- 12/2000 ” … Jeff Bobier, director of operations, said, “We could not be more pleased with the level of excitement that our Wish wireless product has generated. Our client partners are delighted with the progress of the deployments in Florida and across the US.””
- 2/2003 “… Karason said he found out later that the whole demonstration was fraudulent, “using illegal power, illegal equipment, preloaded stuff on computers that we were told was downloaded over the system, etc., and in fact the Icelandic system did not work at all, as the people running it found out after the presentation — when the ‘magic dust’ had disappeared.””

Finally, an interesting article from the early days of xG Technology 4/2003. Note that
“A small startup claiming breakthroughs in phase-coherent filter modulation will be demonstrating its signal-processing techniques in analog pager bands later this year, as a prelude to offering its technology for a range of wireless and wireline networks.” “Bobier previously presented details of his work at the Telecommunications Industry Association’s Ventures 2002 show last July. At the time, Bobier claimed that analog paging channels would be able to transmit data at speeds of up to 150 Mbits/sec. He also began work last summer in reducing a typical TV transmission channel for coaxial cable from 6 MHz to 30 kHz.”
In other words he is talking about a spectral efficiency of 200, even bigger than that of Ultra Spectral Modulation (USM) who were going to demonstrate spectral efficiency of “only” 100! (Such a system would require an SNR greater than 600 dB.) Unlike Walker of VMSK fame and the USM folks he apparently managed to get rid of this particular delusion (xMax has a spectral efficiency on the order of 1 which is of course feasible). So he is learning, but still has some fundamental misconceptions about signal and systems, filters, and communication theory as will be immediately recognized by any competent communication engineer reading his patents.
Aren’t there any competent communication engineers on the xG team who could teach him this basic stuff? Or are they carefully hiring people who will not challenge the founder? Surely when they tested their systems he must have realized that the performance claims they have been making all along are based on serious conceptual errors (as xG’s own BER curve shows), not unlike the errors leading him to try and develop a system with spectral efficiency of 200! There is so much to learn in order to put together a working wireless network, and so little time …
