WIGWAM — Wireless Gigabit With Advanced Multimedia Support
| Overview |
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.
Besides typical application areas, i.e. "hot-spots" and
home/office scenarios, WIGWAM covers the toppic of providing high
data rates for high mobility application scenarios. The Telecomunicaiton
Network Group (TKN) of TU Berlin is involved in the sub-project
"Radio Links With Highest Data Rates on Fast Altering Radio
Channels Based on WLAN Principles" in which it contributes
the support for fast and seamless handover.
