Section 3. Visitor Wireless
3.1 How do I get Visitor Wireless in my building? Campuses, Colleges, and Departments may opt-in to have Visitor Wireless in their building(s) or in certain areas of their building(s).
3.2 How much does adding Visitor Wireless cost? There are no fees for adding this opt-in feature to your existing wireless network. If you don't already have wireless in your building, normal backbone and LAN charges will apply. Consulting with an engineer at TNS Service Inquiry or by phone at (814) 865-1696 could provide more detailed information.
3.3 Does adding Visitor Wireless require any special equipment? Your LAN equipment must support 802.1Q technology.
3.4 Where can I get Prepaid Visitor Wireless Coupons to hand out to my Guests? Holders of Penn State Access ID's may purchase prepaid coupons from Penn State's Computer Store.
3.5 Prepaid Visitor Wireless Coupons are good for one session...What is a "session?" Each Prepaid Coupon comes with a "scratch off" access code and is good for one 24-hour session that begins when the coupon is first activated. The session can be enabled no matter how many times the wireless device is powered off and on within the 24-hour period. Sessions are only valid on the campus where the coupon is first used and where Visitor Wireless access is available (see Visitor Wireless Locations). Prepaid Coupons obtained elsewhere (e.g. McDonalds) won't work on the University's Visitor Wireless network.
3.6 Can Students use Visitor Wireless? Anyone adhering to the Terms and Conditions of the Visitor Wireless provider may use their network.
3.7 Are Penn State computing resources secure from users of the Visitor Wireless network? Users of the Visitor Wireless Service are issued IP addresses from the Service Provider. Virtual networking technology forces that these addresses can only be routed to the Provider's network. At that point, Penn State's computing resources are as secure as from any other public Internet source.
Section 4. Technical Information
4.1. What is the IEEE 802.11 Standard? IEEE is the Institute of Electrical and Electronics Engineers, a standards body that promotes design specifications to ensure compatibility between different manufacturer's products. 802.11 is the IEEE designation for the particular kind of wireless networking technology that is being
4.2. What kinds of wireless devices can access Penn State Wireless? Penn State Wireless is designed for use by 802.11 wireless capable laptops such as those that have either a built-in wireless chipset or a wireless network interface card (NIC), which fit into the PCMCIA card slots of laptops. We have found that 802.11b wireless capable laptops are not compatible with the Penn State Wireless 2.0 service.
