Summit Data Communications has taken embedded Wi-Fi a step further, with the release of two radio modules, one in compact flash another in PCMCIA form factors, supporting Windows CE and version 4.0 of the Cisco Compatible Extensions (CCX).

CCX is a set of interfaces that ties into functions and features in Cisco wireless access points and controllers. In effect, CCX code optimizes third-party clients for Cisco WLANS.

An IEEE standard that lets a wireless LAN achieve data rates as high as 54 Mbps. Thus, the standard can support many broadband applications, letting wireless users access the most demanding applications.

To dramatically increase throughput, 802.11a proponents had to solve a major challenge of indoor radio frequency: delay spread in the current 2.4-GHz, single-carrier, delay-spread system.

The 802.11a standard cleverly solves this through a modulation technique called Coded Orthogonal Frequency Division Multiplexing (COFDM), which has found earlier application in European digital TV and audio transmission.
