Hello:
I'd like to say that this might be a very bad move for a lot of my students. I am checking with the vendor right now, but I believe that the primary device most of my blind students use to access the internet is a B only device. I should be hearing back in the morning, when do we expect the changeover of air bears? I need to prepare my students if my suspicion is correct.

Subject: [Micronet] AirBears Service Changes
Folks,
In a continuing effort to provide the best AirBears experience, IST will
be disabling the 802.11b wireless network speeds for use as part of the
AirBears wireless network at UC Berkeley. Disabling these speeds will
allow a more efficient transmission of data between access points and
end user devices. Users will continue to have access to the higher
speeds supported by 802.11a, 802.11g, and 802.11n.
For the vast majority of AirBears users, there will be no change to the
appearance and functionality of the AirBears network. Users should
experience a decrease in the time to load a page and experience network
content. It should be noted that with AirBears and all wireless
networks, users are accessing a shared medium and actual performance
will be affected by the number of users in an area and interference with
the radio signal provided by the access point.
A very small number of users, probably less than 0.2% based on our
current statistics, are still equipped with 802.11b only wireless
network adapters and will not be able to connect to AirBears with this
equipment after the change. Most of these users would be utilizing
equipment that was manufactured or delivered before 2004. For these
users, it will be necessary to acquire a wireless network adapter that
is compatible with their device and will support a minimum of 802.11g.
All adapters that are compatible with AirBears will carry the "Wi-Fi
certified" logo, with the "a", "g", and/or "n" borders around the logo.
Support for 802.11b only devices on AirBears will officially end as of
December 31st, 2011.
Regards
Isaac
