The Sandberg Wireless N300 PCI gives you wireless network access from your desktop computer. The card is based on 802.11n technology, which is significantly faster and has a longer range than earlier wireless network standards. 802.11n is backwards compatible with earlier wireless network standards such as 802.11g and 802.11b, so you can also easily use older wireless equipment with your new N300 PCI. The card allows you to connect to wireless networks wherever you have access to them – removing the need for cables.
