802.11g++
Term for an accelerated variant of WLAN based on
IEEE 802.11g.
The 802.11g++ procedure functions as a kind of "turbo
mode" for the IEEE 802.11g WLAN standard. By
implementing special accelerations methods (frame
bursting, packet aggregation), it increases the maximum
gross transmission rate to 125 Mbit/s - as opposed to
54 Mbit/s for radio communication compliant with
IEEE 802.11g. As a result, the maximum net data
transmission ´rate increases by around 35 percent, from
approximately 25 Mbit/s to approximately 34 Mbit/s.
If multiple devices that support the turbo mode
802.11g++ are located in the same WLAN radio cell, they
can communicate with each other at higher speeds.
However, this results in slight disadvantages for all other
devices within the WLAN radio cell that do not support the
turbo mode.
Since 802.11g++ is merely a non-standardized variant of
WLAN, the turbo mode works only between devices
designed for it by a single manufacturer, because even
when identical chip sets are used, the implementation of
the procedure defined in 802.11g++ differs slightly from
one manufacturer to the next.
ADSL
abbreviation for Asymmetric Digital Subscriber Line
designates a fast kind of file transfer that works with
standard copper cables and transports signals in both
directions at different speeds (upstream at 640 Kbit/s and
downstream at up to 9 Mbit/s).
ADSL2
abbreviation for Asymmetric Digital Subscriber Line 2
ADSL 2 (G.992.3) is a further development of the ADSL
norm G.992.1/G.992.2).
