What is WIMAX?
13-Mar-09WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless “metropolitan area networks”. WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 – 10 miles (5 – 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 – 300 feet.
Atheros is leading the WLAN performance innovation curve with our 802.11n XSPAN with Signal-Sustain Technology which delivers ~50% greater throughput at range versus conventional 2×2 MIMO solutions. In fact, we have a history of looking for the most novel ways of delivering the very best wireless performance. We invented the first standards-enhanced WLAN technologies with Super G [...]

Wireless System Overview
08-Jan-09Since ancient times, humans have learned to cooperate in order to overcome nature’s limitations. There is a growing need to exchange information and services quickly and effortlessly across local, national and now global communities. People want the ability to communicate any time, anywhere in our mobile society. Wireless technologies make our mobile society possible. Apple’s iPod library syncs up with a laptop computer, drivers navigate their cars over uncharted roads, …
What is WPA security?
30-Nov-08WPA/WPA2-Personal (PSK) stands for Wi-Fi Protected Access with a Pre-Shared Key, and was developed by the Wi-Fi Alliance to address the security weaknesses associated with WEP security. WPA/WPA2-Personal (PSK) is a standards-based security technique where each packet of information is encrypted with a different code, or key. Since the key is constantly changing, WPA/WPA2 is very secure.
