IEEE 802.11b-1999/Cor 1-2001

802.11b-1999/Cor 1-2001 is a focused corrigendum to the wireless LAN medium access control and physical layer specification for higher-speed operation in the 2.4 GHz band. It addresses corrections to the original 802.11b-1999 text, helping align implementation details, terminology, and technical requirements. For communication, networking and broadcast technologies, this document matters because it supports more consistent interpretation of the standard and reduces ambiguity in design and compliance work.

What is 802.11b-1999/Cor 1-2001?

This standard document is a corrigendum for the 802.11 wireless LAN specification, specifically the higher-speed PHY extension in the 2.4 GHz band. The reference to 802.11b-1999/Cor 1-2001 indicates that it does not introduce a standalone wireless system, but corrects or clarifies parts of the earlier text. In practical terms, it is used to refine the MAC and PHY requirements so engineers, testers, and procurement teams can work from a more accurate technical baseline.

Where is 802.11b-1999/Cor 1-2001 used?

802.11b-1999/Cor 1-2001 is relevant wherever early 2.4 GHz wireless LAN equipment, documentation, or conformance testing needs to be interpreted against the corrected specification. That can include access points, client radios, embedded network modules, and engineering test environments that reference the 802.11b PHY extension. It is especially useful in technical libraries, product compliance reviews, and legacy network support work where precise wording in the standard affects implementation decisions.

Why is 802.11b-1999/Cor 1-2001 important?

This corrigendum helps reduce errors caused by unclear or inconsistent wording in the original wireless LAN specification. By providing a corrected reference, 802.11b-1999/Cor 1-2001 supports more reliable design interpretation, test planning, and standards-based procurement. That matters when teams need to compare equipment behavior against a stable technical requirement set, especially in communication and networking applications where even small specification differences can affect interoperability and performance expectations.
