Intel PRO/Wireless 3945ABG Wireless Network Controller
I would like to remind you that the mobile Centrino platform, as well as its new reincarnation aka Centrino Duo, includes not just the CPU and the chipset, but also a WiFi controller. Therefore, Intel paid special attention to upgrading this component, too. The wireless network adapter bundled with the Core Duo and Core Solo platforms – Intel PRO/Wireless 3945ABG (Golan) – differs from its predecessors by the connection to the chipset South Bridge via the PCI Express x1 bus. As a result, it takes a lot less space inside the notebook. Moreover, according to the details reported by the manufacturer, the new WiFi component is more immune to interferences, and imposes less interference over other devices, such as Bluetooth in the first place.
I have to stress that in terms of supported features Intel PRO/Wireless 3945ABG component is not very much different from its PCI counterparts that have been used in Centrino platforms before. However, I would like to say that Intel has also accompanied its new WiFi adapter with the updated modified software that features slightly different interface and is specifically optimized for IP-phone environment.
Other than that the features of Intel PRO/Wireless 3945ABG are quite common: it supports IEEE-802.11 a, b and g and WPA/WPA2 encoding algorithms.
