Caltech Wireless Network

The Caltech wireless networks deployed by IMSS support many advanced features, including secured authentication and advanced encryption of wireless traffic. The wireless connection protocol supported is IEEE 802.11b/g. In addition, campus guests will be able to connect without prior registration, which can enhance conference attendance on campus.

Locations and status of new wireless network deployment

Which network is right for me?

In order to take full advantage of the new wireless networks, users are urged to update the device driver for their wireless network card, as well as the underlying operating system (e.g., Windows, Mac OS X, Linux, etc...). Please see the following page for a list of required and recommended hardware and software to connect to the new Caltech wireless networks, in particular for the encrypted wireless network "Caltech BeaverNet".

Requirements and recommendations on hardware and software

The new system allows a user to connect to any one of the three new wireless networks (SSID) at any single time. The following table summarizes the features associated with each SSID.

SSID Authentication
Required?
Wireless Traffic
Encrypted?
Wireless Speed
(per user)
Network Protocol
Restriction
Caltech Guest No No Up to 11 Mb/s Only HTTP, HTTPS, SSH and VPN* are currently allowed
Caltech Registered MAC address registration No Up to 21 Mb/s No IP protocol restriction
Caltech BeaverNet IMSS (access.caltech) account Yes, using AES Up to 40 Mb/s No IP protocol restriction

*In order to create a VPN tunnel over the wireless network, the VPN client must be set to use IPSec over UDP or TCP, NAT-T, OpenVPN, PPTP or L2TP. Native IPSec VPN tunnels are not supported.

In general, use of Caltech BeaverNet is recommended for those users who can take advantage of it.

  • If you have a relatively current computer that supports or can be upgraded (as described above) to support 802.1X WPA2 Enterprise authentication, selecting Caltech BeaverNet will provide the best features, performance, and security.
  • If you have an older computer or iPhone that does not support 802.1X WPA2 Enterprise authentication, select Caltech Registered. Be sure to register your MAC address with us.
  • If you have a device that does not support authentication or does not have a user interface to enter authentication credentials, select Caltech Registered.

For instructions on how to connect to each of the SSIDs above, please follow the links below.
