A brief history lesson:
Prior to the announcement from Cisco of “Universal Access Points” you had to select an access point based on which regulatory domain it would operate within. Regulatory domains are simply places in the world with certain laws and regulations pertaining to radio frequency devices (mobile phones, radios, access points, etc.). In the world of Cisco this meant that an access point for use in Germany would have a different part number than one used in the United States. This led to much frustration and confusion.
The good stuff:
Cisco has announced Universal AP’s which are a single part number per access point model (2700, 3700, etc.) rather than the myriad of part numbers aligned to each and every regulatory domain. The details on how this works can be found in the following blog post.
