Re: Ham Radio and ATT "U-Verse" IPTV-Internet-Phone Problems
Yes, ADSL2+ utilizes 1.138 - 2.2123125 MHz over twisted pair. However, different flavors are being pushed in different markets. Currently, these other goodies are being deployed in various places:
VDSL utilizing 1.1 - 12 MHz over twisted pair
VDSL2 utilizing 1.1 - 17.66 MHz over twisted pair
VDSL2+ utilizing 1.1 - 30 MHz over twisted pair
None of these appear to have much ability to reject ingress from RF or random electrical noise. Their current solution appears to be to deploy new STB's that will buffer several minutes of programming to allow time for retransmission of packets to correct errors in the video downstream. They are also diddling with using shielded CAT5 instead of twisted pair, but as far as individual subscribers living next to a ham radio operator, they currently don't seem to have much to offer at this time.
