3. Overview of OWL Version 2

It is estimated that there are around three hundred access points currently deployed within the University. The vast majority of these are Cisco Aironet 1100 and 1200 series, as purchased by departments and colleges following the advice of the OUCS Networks team.

The Aironet access point was selected because of its ability to operate in both an autonomous, and lightweight, mode. In autonomous mode, the access point contains a full configuration, and runs independently of any other network hardware. In lightweight mode, the access point is slaved to a mother-ship controller appliance, and no configuration is stored on the access point when it is without power.

OUCS has now been allocated funding to run a set of controller appliances for the collegiate University. These appliances can manage a large number of lightweight-mode access points as a cloud, providing balanced power level, SSID and radio management across all sites. With the unit's blessing, its current Cisco access-points can be easily migrated to lightweight mode.

In addition around 300 access points will be purchased. They will be deployed over a period of three years, to around 60 sites within the University, with the sites being selected by and evenly distributed between each of the divisions. Those sites nominated by the divisions have now been published, and will be receiving surveys over the coming months.

Further wireless coverage in any department or college is possible by OUCS offering to extend the service described above, on a cost-recovery basis.
