The AES-based privacy mechanism is invisible to entities outside the 802.11 MAC data path. Bit 5 of the Mode field is used to signal an Extended Packet number field of 6 octets. For standard length Packet number/ IV fields (as with basic WEP, TKIP and AES-OCB) this bit is set to zero, for extended packet number field the bit must be set to zero.
The 802.11b wireless networking standard with its ease of use and relative low cost has made it a very popular technology Millions of households that were never 'wired for data' are using this technology to share high-speed connections from anywhere in or around the house (like by the pool)! The 802.11 application framework is comprised of modular PHY and MAC blocks implemented using LabVIEW Communications. It is designed to run on the powerful Xilinx Kintex-7 FPGA and an Intel x64 general-purpose processor, which are tightly integrated with the RF and analog front ends of the NI software defined radio (SDR) hardware. Plus, you can get connected with your clients or friends through the essential ports without the hassle of dongles using its wireless 802.11 a/b/g/n protocol. Additionally, it runs with the Windows 10 Pro 64-bit operating system for a user-friendly interface. When WEP is active in a wireless LAN, each 802.11 packet is encrypted separately with an RC4 cipher stream generated by a 64 bit RC4 key. This key is composed of a 24 bit initialization vector (IV) and a 40 bit WEP key. The encrypted packet is generated with a bitwise exclusive OR (XOR) of the original packet and the RC4 stream.

Encryption and Authentication > Cisco 802.11 Wireless WEP keys are often referred to as 40- and 104-bit, or 64- and 128-bit. The terms are interchangeable. 40-bit and 64-bit keys offer the same level of protection. So what's happening to the other 24 bits? Those "missing" 24 bits are the key's initialization vector. So, in a 64-bit WEP environment, only 40 bits are considered part of the actual key.
IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) protocols, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) Wi-Fi computer communication in various frequencies, including but not limited to 2.4 GHz, 5 GHz, 6 GHz, and 60 GHz frequency bands.
