What are the exact differences between the 2100 and 4400 ?

The Cisco 2100 Series Wireless LAN controllers are designed to provide basic, secure

coverage, while Cisco 4400 Series controllers provide flagship performance and scale that is

needed for campus and medium and large branch offices. While the Cisco 2100 Series

supports transaction-oriented wireless environments, the 4400 Series is recommended for

high-data-rate and multicast-intensive applications such as large data files, video, push-to-talk.

The wireless controller feature comparison matrix in Table 1 summarizes these differences.
