T-Mobile works to tighten Wi-Fi security

Tuesday, 14 October 2003, 1:24 PM EST

The Bellevue, Wash.-based wireless company announced on Monday that it has been testing the 802.1x security specification at selected hot spots, which are public places where wireless Web access is available. It said it plans to add support of the specification across its entire Wi-Fi network in the United States by the second quarter of next year.

Securing the transmission of data over wireless networks is a major concern for information technology managers, and so far, it has been a limiting factor in businesses' adoption of Wi-Fi technology, according to analysts. However, as more traveling professionals use the technology as a convenient means of accessing corporate data and e-mail, information technology administrators may feel more comfortable; public wireless access should become more secure as specifications such as 802.1x and Wi-Fi Protected Access (WPA) become more prevalent.

The 802.1x specification tackles a major security concern over access control and the use of Wi-Fi wireless networking technology: It stops information from being intercepted while it is being transferred between a Wi-Fi network and a client computer or other device.
