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, 802.11a, 802.11n, 802.11ac wave 1 and 802.11ac wave 2 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. 802.11n WLANs can operate up to 600Mbps. 802.11ac WLANs can operate up to 6.77 Gbps.
Yes, whenever you can you should use the wired network to do your work.
CCRI will no longer be supporting the 802.11b standard. With the current standard of 802.11ac wave1 installed and configured, the maximum bandwidth any one device shall achieve will be no more than 600Mbps 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 many factors. Some of these factors are: the ty pe of device you are using, how many users are connected to the AP you are connected to, the signal strength you are currently using, how many streams your device can handle with your current AP. 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. The Public can connect to the CCRI_Guest wireless network and use the self-service sign in process to get connected for the day.
