Chapter Description

On top of normal networking issues, WLAN adds a couple of new challenges, such as Layer 1 (radio frequency [RF]) issues; a set of L2 protocols, such as IEEE 802.11; and the need for agencies to regulate the use of this shared medium, as the authors explain in this excerpt from their book, CCIE Wireless Exam (350-050) Quick Reference.
