Appendix 1B Summary of Important Standards Organizations

Figure 1B.1 provides an overview of the standardization process. The process starts in a group, for example, IEEE 802.11 or GSM, which implements the standard. The implemented standard is then moved for the approval of a regional organization such as the European Telecommunications Standards Institute (ETSI) or the American National Standards Institute (ANSI). The regional recommendation is finally submitted to world-level organizations, such as ITU or ISO/IEC, for final approval as an international standard. There are a number of standards organizations involved in wireless networking. Table 1B.1 provides a summary of the important standards playing major roles in shaping the wireless networking industry. This table helps the reader as a reference point while reading the text.
