Which wireless standard is commonly used for Voice over WLAN (VoWLAN)?

• A. IEEE 802.11
• B. IEEE 802.3
• C. IEEE 802.15
• D. IEEE 802.16

Answer: (A)

Voice over WLAN (VoWLAN) primarily utilizes the IEEE 802.11 wireless standard. This standard defines a set of protocols for implementing wireless local area network (WLAN) communication in various frequencies, primarily in the 2.4 GHz and 5 GHz bands. One of the key features of the IEEE 802.11 standard is its ability to support real-time voice communications, which are critical for VoWLAN applications. The standard allows for high data rates and is designed to maintain the quality of service (QoS) necessary for voice traffic, including prioritization of voice packets over other types of data. This ensures minimal latency and packet loss, which are crucial for clear and uninterrupted voice communication. The other standards listed serve different purposes. IEEE 802.3 is primarily for wired Ethernet networks, IEEE 802.15 focuses on personal area networks, and IEEE 802.16 relates to broadband wireless access technologies, none of which directly cater to the specific needs of VoWLAN like IEEE 802.11 does.
