Can guests access the wireless network?

UW-W Faculty and Staff may request access for guests at http://www.uww.edu/icit/helpdesk/guests/index.html . If you have special guest needs please contact the Technology Support Center Helpdesk at x4357 or helpdesk@uww.edu .

These industry standard network security protocols require users to login with your Net-ID before network access is granted. Although these security measures require a few extra steps to get your device connected to the wireless network for the first time, they provide an important layer of security for your data on the campus network.

How does wireless work?

UW-W is implementing IEEE 802.11a/g/n wireless standards on campus that use the 2.4GHz and 5GHz radio frequencies. 802.11a/g/n provides 11-54 Megabits per second of bandwidth. All users connected to a given access point share the available bandwidth. It is estimated that about 13 - 18 users can be active on a single access point simultaneously. However, if one user is using a large amount of bandwidth (i.e. - uploading or downloading large amounts of data) the other users can experience degradation in service or poor network response.

Can I use my wireless enabled PDA or smartphone on  the UW-W Wireless Network?

Although PDAs and smartphones are able to connect to our wireless network, iCIT provides limited support. Specific instructions for connecting an iPhone are available on the Mobile Devices page.

What is the range of a wireless signal? How far away can I be from an access point and still use the wireless network?

The range of wireless varies with a variety of factors including the type of space, the antenna used, the access point and environmental interference. In the typical indoor environment, the access point will provide coverage within 150 feet. In outdoor areas, the antenna design and gain can increase the coverage area to several hundred feet. Generally, the closer the wireless access card is to the access point, the higher the transmission speed.

Is the wireless network secure?

Your data is secure on the UW-W wireless network.  The campus wireless network uses a security standard known as WPA (Wi-Fi Protected Access) Enterprise, or 802.1X WPA. WPA Enterprise can use several methods to protect your data. For those who like the technical information, you may want to know that UW-W uses the PEAP (Protected Extensible Authentication Protocol) authentication protocol and TKIP (Temporal Key Integrity Protocol) encryption.

These industry standard network security protocols require users to login with your Net-ID before network access is granted. Although these security measures require extra steps to get your device connected to the wireless network for the first time, they provide an important layer of security for your data on the campus network. 

Additional Security

It is important to remember that wireless encryption is not intended to be your only security. Wireless encryption is just meant to try to make a wireless network as hard to "sniff" as a wired network. It is still important to follow safe computing practices.

When is it better to use a wired connection instead of wireless?

As a general guideline, a location where a specific computing device will be frequently used or permanently located should be connected to the network via a "cabled" or "wired" LAN connection. This includes portable and non-portable computing devices. Wireless networks should only be used for low-volume mobile computing.

Wireless networks are limited to transmitting 11-54MBps and are susceptible to interference from environmental conditions and other devices that produce radio waves in the 2.4GHz and 5GHz range (2.4GHz and 5GHz portable phones, cordless headsets, microwave ovens, two-way radios and devices using Bluetooth technology).Wired connections on the other hand enjoy a dedicated 100MBps connection that is not vulnerable to interference or environmental conditions.
