Addendum: Service Change - Wireless Network (Pittsburgh Campus)
The following is an addendum to the 802.11b wireless client notice that was recently posted (see Support to be Discontinued: 802.11b Wireless Client).
(US Eastern Time)
DATE & TIME: August 17, 2012
Computing Services is making a technical change to ensure a high-quality experience for everyone who uses the campus wireless network. The specific change we will be making is to turn off the ability for older 802.11b wireless clients (such as laptops and mobile devices) to connect to the wireless network. This change will take effect on Friday, August 17th, 2012.
The 802.11b wireless standard was formally adopted in 1999 and devices supporting it have been in use at CMU since early 2000. The original deployment of the wireless network across campus included a number of wireless cards that used this standard. Since then, the campus network has been upgraded multiple times, most recently in 2008 to support the latest high-speed 802.11n wireless standard. Wireless clients that are only capable of using 802.11b significantly affect the performance of nearby clients that use more modern standards.
Wireless clients that use the older 802.11b standard are in very limited use across campus. Nearly all wireless cards and devices sold since 2003 support newer standards. ALMOST ALL WIRELESS DEVICES IN USE TODAY WILL NOT BE AFFECTED BY THIS CHANGE. Since the number of clients using only 802.11b is extremely small, Computing Services will be sending direct notifications to anyone who is still using an 802.11b-only client and may be affected by this change.
After this change is made, the campus wireless network will support connections from wireless devices using the 802.11a, 802.11g, and 802.11n standards.
If you have any questions or concerns about this change, please contact the Computing Services Help Center (412-268-HELP or firstname.lastname@example.org), or contact your DSP consultant.
