Very high rate digital subscriber line (VDSL)
A member of the DSL family of copper loop enhancing
technologies. VDSL is envisaged as the fastest copper
transmission technology for the local loop. While VDSL
protocols have yet to be standardized, it is likely that
VDSL will be symmetric and suitable only for shorte
distances than ADSL (asymmetric digital subscriber line).
VDSL, ADSL, and FTTH will likely coexist with each other
and with cable modems as broadband access technologies.
Very High Frequency (VHF)
The part of the radio spectrum from 30 to 300
megahertz, which includes TV Channels 2-13, the FM
broadcast band and some marine, aviation and land mobile
services.
