With all the new air interfaces (GPRS,EDGE,CDMA2000, ect.) I find it hard to believe that this unit can take the layer 3 massaging, strip it down to the IMEI and Tel Number. Lets now forget the various freqs that the unit would need to cover. Surprisingly there is no data on the FCC's OET site. Hmm...........

Some of their statements are confusing..............

"Due to FCC Regulations , power output is that of an industry standard cellular
tower, but since communications is not a requirement, the system has
additional range of projection and reception."

Power output of a Cellular tower???

Who do they think they are talking to?
