Airgo AGN1012MP, AGN0923AR and AGN1223AR True MIMO Enhanced 802.11a/b/g Adapter, Competitive Wireless LAN Performance Evaluation versus Non-Airgo Equipment
25 September 2005
Airgo Networks, Inc. commissioned The Tolly Group to evaluate a wireless router and wireless laptop PC that are based on Airgo Networks’ True MIMO™ antenna and chipset design. True MIMO (Multiple Input Multiple Output) uses a smart radio technology that promises to increase speed, coverage, and reliability for wireless systems.
Tolly Group engineers tested the Airgo AGN1012MP module embedded in a Samsung Electronics Co. Ltd. X25 laptop PC. The Samsung laptop is a 802.11a/b/g solution that has been enhanced with Airgo’s True MIMO technology to improve wireless performance while maintaining interoperability with the millions of 802.11b, 802.11g, and 802.11a devices across the globe. It was paired with a Linksys WRT54GX (also with an embedded Airgo AGN1223AR radio module) in tests of 2.4-GHz 802.11b/g. The Tolly Group also tested the Samsung X25 in a 5-GHz 802.11a scenario, pairing it with a SOHOware, Inc. AeroGuard AGN1200 access point that utilized Airgo’s True MIMO technology.
Engineers measured the downstream effective throughput (from the AP/router to the client) of the Samsung X25 laptop PC and the Airgo-based APs to which it was paired in the 802.11 b/g and 802.11a tests. In addition to throughput, engineers measured the range at which the pairs could communicate at a minimum of 10 Mbps across varying distances in an effort to establish a credible effective coverage area metric. Effective throughput is a metric that combines throughput with coverage area.
The Airgo-enabled devices were tested against product pairings that utilize Intel Corp. and Broadcom Corp. chipset technology.
