Samsung laptop ships with MIMO wireless technology

MIMO capability amplifies the speed and range of wireless networks

Samsung Electronics will ship its new X20 notebook with an embedded wireless LAN (WLAN) chip from Airgo Networks that allows users to speed up wireless connections.

Airgo has designed a WLAN chipset that uses MIMO (multiple-input multiple-output) technology to amplify the speed and range of wireless networks.

Samsung's X20 laptop PCs will come with Airgo's True MIMO chipset, which works with 802.11a/b/g networks but also allows users to connect to WLANs at faster speeds than current technology allows.

MIMO technology improves WLAN speed and range by using two or more antennas to send and receive multiple streams of data over a single channel.

Airgo's MIMO technology supports WLAN connection speeds of up to 108Mbps (megabits per second), according to the company, though real-world connection speeds generally fall short of what WLAN vendors promise.

MIMO technology is slated to become part of 802.11n, the successor to the current crop of WLAN standards. 802.11n is currently under debate by the Institute of Electrical and Electronic Engineers (IEEE). The standards body has yet to reach agreement on exactly what type of MIMO technology will become part of the standard, prompting access-point vendors to ship products equipped with MIMO technology before the standard has been fully determined.

Airgo is advancing one type of MIMO technology before the IEEE; meanwhile, a group called TGn Sync, composed of companies such as Intel and Atheros Communications, is pushing a different flavour of the technology. WLAN connections using the 802.11n standard could reach several hundred megabits per second, according to the two main proposals.
