Wireless Networking has arrived
UNC Charlotte. Wireless Networking will allow you to access web enabled applications and resources from your
wireless enabled device without the need of plugging into a network data jack. 802.11b Wireless Access Points
are currently being installed in select locations around campus and as budgets allow, we hope to have the majority
of campus covered for wireless access. |
The Wireless Networking communication standard that will be supported here on campus will be the IEEE 802.11b standard. While there are certainly other technologies available today, Bluetooth, 803.11a, 3G, we feel that at this time only the 802.11b offers a stable and mature platform. 802.11b wireless offers 1 to 11MB of shared bandwidth at distances of up to 350ft. The radio transmissions is in the 2.4 GHz range, (The same as your home wireless telephone) and offers a signal strength of 100mW. This allows a range of 100ft at 11MB and 350ft at 1MB. Please keep in mind that wireless interference such as physical objects like a wall, and non physical objects like microwaves, may affect the performance.

To connect to the wireless network you will need the following items:
- A Wireless Ethernet Card
- You will need an 802.11b compliant wireless network card installed in your computer.
Regardless of brand, it is critical that the NIC be 802.11b compliant.
Other types of wireless adapters will not function.
- SSID
- The SSID is the identifier of a Wireless Network. Sometimes it is called
the Radio Network Name. It is used to separate multiple Wireless Networks that may overlap one another. The current SSID used for accessing the campus wireless network is uncc49er. You will need to configure you wireless
NIC card to use this SSID.
- A Valid Novell or 49er Express Account
- Currently a valid Novell
or 49er Express account (Faculty or Staff Account) is required for authenticate
and access to the wireless network system.

802.11b wireless offers 1 to 11MB of shared bandwidth at distances of up to 350ft. The following items will decide just how fast a wireless network connection you will get.
-
- Physical Obstacles
- Things like walls, glass, and people standing between you and the Access Point Antenna will affect your transmissions speeds. The more
obstacles you make the signal go around, the slower the network connection you will have.
- Number of Users
- Wireless Networks are know as "Shared Networks." That is to say, you will share the bandwidth with whoever else is using the wireless network at the same time you are. (Similar to Cable Modem service.) If 2 people are using a 11MB wireless network, then they both are actually getting only about 5.5MB of Bandwidth each when they use the network at the same time.
Web browsing performs generally quite well in a shared environment since all you are doing is downloading html pages. Listening to your favorite MP3 from a Napster Site or viewing the latest news video from CNN however, would probably not be a
pleasurable experience. If you need to do these types of activities, it is HIGHLY
ADVISABLE to set your stream rate in those programs to a low setting. 56K for example.
- Other Interference
- 802.11b operates in the 2.4 GHz range with a signal strength of 100mW. It is conceivable that someone or something could generate a signal within this range, and thus disrupt your signal to you. This is the same frequency range as the home wireless phones you can buy at your local electronics store as well as several other popular wireless devices. Microwave ovens are also known to disrupt 802.11b wireless networks.
- Distance
- The farther away you go from the Access Point Antenna, the slower your wireless network connection will be. Generally you will get speeds of 11MB up to about 100 feet from the Access Point. Between 100 and 200 feet, you can expect 5MB of bandwidth. After that, service drops to 1MB of service until you are completely out of range. Remember, these figures are for optimal conditions. All of the above items will play a role in you final wireless connection speeds.

You can access anything on the network that you can normally access via a web browser.
Technically, this means TCP port 80. There is no direct connection to the campus network from the campus wireless network.

Keeping your drivers up to date is the best way to achieve optimal performance.
Check your NIC manufacturers website regularly to ensure you have the latest
drivers.

Currently, encryption is only available for faculty and staff. This
encryption is via a Virtual Private Network (VPN) tunnel. A VPN client is
required on the user's machine. UNCC User Support or Help Desk has
information on how to acquire the necessary VPN client software. Back to the Top
Currently the
Wireless Network is installed in the following locations.
