Campus Wi-Fi Options: AirBears2, AirBears, AT&T, and CalVisitor

IST offers the following options for accessing the campus Wi-Fi network. Click here to download a poster for your department! 

AirBears2 provides simplified authentication for campus users, and improved confidentiality for data being transmitted wirelessly. 

AirBears2 Key

In order to use AirBears2 you must create an AirBears2 key. This can be done by any user who is eligible for access to the Campus Wi-Fi network. 

To generate your AirBears2 key, go here:

To check eligibility for Campus WiFi you can go here: 

For more information on managing your AirBears2 key, see the IST KB articles on the topic:

Guests can not use AirBears2. Information on guest access to the campus WiFi network is located here:

Accessing AirBears2

Once you have your AirBears2 key, you can configure your device or computer to use AirBears2. Just select it as your WiFi network, accept the certificate that is offered (this secures the association process), and log in with your CalNet ID and your AirBears2 key as the password. Once you have done this the first time, your device should automatically use AirBears2 whenever you are within an area that it is provided (inside almost all Campus buildings).

More specific details on using AirBears2 for different types of computers and devices are available in the IST KB:

Airbears is the basic wireless access to campus networks with web-based connection. It provides access to all students, faculty and staff and allows for the creation of guest accounts for campus visitors. 





AT&T Wi-Fi Project

We have embarked on a joint project with AT&T that will enable us to provide nearly 100% full wi-fi coverage inside campus buildings, with AirBears running alongside the AT&T SSID (attwifi). The project will also allow us to extend the 'attwifi' SSID to the student residence halls. Anyone with a smart phone, laptop, or mobile device that is enabled for wi-fi will be able to use the AT&T wi-fi service. Users with an AT&T data plan will be able to connect automatically, while others will have the option to purchase blocks of time on the AT&T service. 






*Note: The maximum transmission rate is the representation of the speed data can flow in a single direction over the wireless devices.  IEEE-802.11 devices utilize a shared medium, resulting in a half-duplex operation.  The actual data rates for end-to-end communication will vary based on the number of users, the quality of the radio signal, and the overall amount of data being passed over the wireless medium.  Typical end-to-end data rates are near 10Mb for the 54Mb rates and 65Mb for the 300Mb rates.


Initial Deployment of AirBears

As of March 16, 2012, there are 1612 total access points installed and operational at UC Berkeley. These access points conform to the 581 IEEE-802.11n draft 2.0 standard with a maximum transmission rate of 300Mb. We are continuing the deployment of AirBears—aiming to provide coverage in all areas inside campus buildings. We are continuing this deployment by installing devices that will utilize IEEE-802.11a/g/n. This will make it possible for users to continue to use their existing devices or to upgrade to the latest technology.
