To Marden: Both Terayon and Qualcom use CDMA which is Code Division Multiple Access. The Q in wireless, Terayon on wire. The trick with both is that the transmission uses a code for separation of data, not time (as in TDM - on wire- or TDMA - on wireless). The advantage of the use of code is that the data which is attached to the code in effect rides on the noise across the air or wire and then when the scrubbing takes place on the receiving end to free up the data, all the original noise and also the noise added during transmission is removed leaving the data attached to the code free, clear and noiseless. This is an explanation from a non technology guy, but think it is accurate. Chaz Note: The reason the Q and TERN have no patent conflict is that the Q has a lock on the means of using CDMA in the air (the air interface) while TERN's patents relate to the use of CDMA on wire.
