A WLAN is a type of Local Area Network (LAN) that uses high frequency radio waves rather than wires to communicate and transmit data. It is a flexible data communication system implemented as an extension to or as an alternative for, a wired LAN.
IEEE 802.11b, 802.11g, and 802.11a are industry standard specifications issued by the Institute of Electrical and Electronic Engineers (IEEE). These specifications define the proper operation of Wireless Local Area Networks (WLANs).
802.11b WLANs operate at speeds up to 11 Mbps. 802.11a and 802.11g WLANs operate at speeds up to 54Mbps.
Yes, whenever you can you should use the wired network to do your work.
With the 802.11g wireless standard you can have a connection of 54 Mb/sec at best (i.e. if you're right next to the access point and you are the only user). However, you rarely achieve the maximum possible speed. This is because of multiple users and signal strength. All users within range of an access point share that bandwidth, so you'll only get the top speed if you are the only person within range of that access point. In addition, as you move away from the access point and the signal gets weaker, the system will automatically slow down to give you more reliable data transfer (sort of like speaking slower so people will understand you better).
The unlicensed nature of radio-based wireless LANs means that other products (ex. 2.4 GHz cordless phones, microwave ovens, garage door openers, Bluetooth™ devices) that transmit energy in the same frequency spectrum can potentially interfere with a WLAN system. Older microwave ovens are a concern, but most WLAN manufacturers design their products to account for microwave interference. RF interference can also occur if two WLANs are located in close proximity to each other. This situation is usually dealt with by placing each WLAN on a different RF channel within allowed frequency range.
Authentication is the process used to verify that a client's device is allowed to use the wireless network.
A computer connected to a network.
An access point connects wired and wireless networks together and enables the sending and receiving of data between wireless clients and the wired network. Using multiple access points increases total system capacity and range. Users can "roam" between access points without losing their connection similar to the way a cellular phone can roam between cellular phone towers.
The Media Access Control (MAC) address of the Wireless Ethernet Adapter is a unique serial number assigned to the device by the manufacturer. Every wired or wireless network device has a unique MAC address.
Yes, faculty, staff, and students can connect to the wireless network by using their MyCCRI username and password.
If you are a new student and have just activated your MyCCRI account, it will take anywhere from 1 hour to 24 hours for your account to be validated.
If you are trying to register as student, staff, or faculty and you have already registered as a Guest, you will not be able to reregister using your MyCCRI account login information. Please call the Help Desk at 825-1112 for assistance.
For assistance with the wireless network please contact the IT Help Desk at (401) 825-1112 or send email to firstname.lastname@example.org.
Wireless devices, such as portable phones, portable digital assistants (PDA) and personal response systems, that broadcast and receive information on the same frequency as the wireless network are not supported on campus due to the possibility of interference.
