General Wireless Information
This information applies to all users of Illinois Institute of Technology (IIT). Wireless networking offers increased convenience for mobile users.
Protocols and Definitions
- "SSID" stands for Service Set IDentifier and is the name identifying a Wi-Fi (wireless) network.
- “802.11b” is a standard that provides data rates up to 11Mbps in the 2.4 Ghz frequency range. IIT wireless infrastructure no longer supports 802.11b.
- “802.11g” is a standard that provides data rates up to 54Mbps in the 2.4 GHz frequency range.
- “802.11a” is a standard that provides data rates up to 54Mbps in the 5 GHz frequency range. IIT wireless infrastructure no longer supports 802.11a.
- “802.11n” is a standard that provides data rates up to 600Mbps in both the 2.4 GHz frequency range (802.11b/g) and 5 GHz frequency ranges.
- “802.11ac“ is a standard that provides data rates up to 1Gbps in the 5 Ghz frequency range.
- "802.11ax" or "WiFi 6" is a standard that provides for higher performance and increased efficiency across a wider possible range of frequencies than any previous 802.11 standards.
- “Encryption” is a technology that secures communication between an end user device and a wireless access point. The IIT-Secure network uses WPA2-Enterprise, AES and 802.1X for data security.
- “Rogue access point” is a device providing wireless access within IIT's property without approval. If a rogue access point is identified, the owner will be required to remove it within three business days. If the device is not promptly removed, technical staff will disable all network access to the rogue access point.
- “Latency” is a measure of time it takes a packet of data to get from one designated point to another.
- “Jitter” is a measure of variation in the latency between packets.
Wireless Network SSID Descriptions
Supports encrypted 802.11ax/ac/g/n. The IIT-Secure network uses WPA2-Enterprise and 802.1X for authentication. Only wireless devices that support WPA2-Enterprise and AES encryption can connect to the network.
Supports unencrypted 802.11ax/ac/g/n only in the 2.4 Ghz frequency range. It is meant to support a wide variety of devices, such as gaming and other entertainment systems, in IIT Housing areas.
Supports unencrypted 802.11ax/ac/g/n. It is the login portal to assist the IIT community to connect to IIT-Secure and provides Internet access to IIT guests, tenants, and IIT supported events.
Supports encrypted 802.11ax/ac/g/n and provides access for visiting guests from member institutions of Eduroam.
Supports encrypted 802.11ax/ac/g/n. The IIT-IoT networks uses WPA2-Personal Pre-Shared Keys (PSKs) for authentication. Only devices registered and assigned a PSK will be able to connect to this network. NOTE: currently in development and testing with limited access on campus. If you feel you have a use case for testing purposes, please submit a Support Ticket for the Network Services team to evaluate the feasibility of adding you to the testing process.
Many wireless and other transmitting devices interfere with the IIT wireless network. Below are some common devices that have a negative impact. While use of these devices is not prohibited, users should be aware of their impact and limit their use or find alternatives when possible.
- Microwave ovens
- Cordless phones
- Wireless video cameras
- Wireless game controllers
- Zigbee devices
- Wireless speakers
- Bluetooth devices
The IIT wireless network supports roaming between access points on the same SSID within the same building. Switching between SSIDs, e.g., IIT-Secure to IIT-Console, requires disconnecting from one SSID and connecting to the other.
Recommendations for Best Experience
Your network experience is an outcome of many factors, including, but not limited to, the following:
- Personal equipment connection capabilities and drivers. It is important to keep wifi drivers updated.
- The number of running applications (eg: web browsing, games, Peer to Peer, streaming, etc) that are using the network. Close unnecessary applications that use the network.
- Wireless infrastructure is a shared environment. Large groups of users can utilize significant bandwidth at the same time. This will impact the speed and quality of the service for individuals. Refrain from using high bandwidth applications in areas where a high number of users are present.
- Higher latency and jitter may be experienced on wireless infrastructure. Applications that are sensitive to latency and jitter should use the wired network.
Downtown, Rice and Moffett Campuses
Downtown, Rice and Moffett campuses also use IIT-Secure.
