Implementing an 802.11 b/g Interface into an Embedded Design
Many industries are realizing the benefits of adding wireless technology into an embedded solution that will allow a company to remotely control, monitor, and access their devices. With this dream of acquiring wireless technology comes the reality of challenges associated with its implementation, such as the need for chipsets and drivers that are difficult to integrate, as well as a strong understanding of RF and TCP/IP networking, among other technologies. Security is another major concern.
It is important to note that when implementing wireless technology, each application will possess individual requirements. There is a significant amount of knowledge and engineering expertise needed to effectively implement an 802.11 b/g interface into an embedded design. This paper will introduce key RF concepts and go over the high level details on how to implement 802.11b/g interface including design trade-offs, hardware / software integration, FCC approvals, wireless security and issues obtaining FCC approval.
