Is 802.11n, the Wi-Fi technology promising to push wireless traffic to 100Mbps, already outdated?
"There
is a common opinion throughout academia, industry and business that the
current wireless technology fulfills neither current nor future
demands," according to those behind the Wireless Gigabit with Advanced Multimedia
(WIGWAM) project. This German-led consortium of corporate and
university researchers says 100Mbps is the bare minimum needed for the
future of wireless. It is using the 108Mbps 802.11n and MIMO technology
as the starting point for bringing 1Gbps wireless into offices and
homes.
WIGWAM is part of the Central Innovation Program "Mobile Internet" which
is funded by the German Ministry of Education and Research (BMBF). The
objective of WIGWAM is the design of a complete system for wireless
communication with a maximum transmission data rate of 1 Gbit/s.
The targeted spectrum is the 5 GHz band and the extension bands 17, 24,
and 60 GHz. Depending on the mobility of the user, the data rate should
be scalable.
The goal is a "1 Gbit/s component" of a heterogeneous future mobile
communication system. All aspects of such a system will be investigated,
from the hardware platform to the protocols, which are subject to very
strong requirements given the extremely high data rate of 1 Gbit/s.
The main application area is the transmission of multimedia content in
so-called hot-spots (see figure below), in home scenarios, and in large
offices where an enormous data rate back-off is necessary, e.g. to
supply the user with short-term high data rates, or to enable a true
plug-and-play without any frequency planning (particularly important in
home scenarios). In order to be able to include such a high data rate
air-interface into a future heterogeneous mobile communications system,
also high mobility applications are covered.
