Technologies for Next-generation Wireless LANs
Osamu Kagami, Ichihiko Toyoda, Masahiro Umehira · 2005
This article reviews wireless local area networks (WLANs) as the most appropriate method to implement the home network services described in the previous articles. After surveying the trends for WLANs, we describe next-generation WLAN technologies including MIMO (multiple input multiple output) transmission, which uses multiple transmitting and receiving antennas. MIMO is the most attractive candidate for high-data-rate transmission and large communication capacity without expanding the signal bandwidth. We also describe various approaches to next-generation WLANs.
