First Wireless LAN Standard Timeline | Generated by AI
Question: What is the earliest released wireless LAN standard?
Answer:
The earliest released wireless LAN standard is IEEE 802.11.
Here is the chronological order of the standards mentioned:
- IEEE 802.11: Released in 1997. This was the original standard, supporting data rates of 1 and 2 Mbit/s in the 2.4 GHz band.
- IEEE 802.11a: Released in 1999. It operates in the 5 GHz band with speeds up to 54 Mbit/s.
- IEEE 802.11b: Released in 1999 (shortly after 802.11a). It operates in the 2.4 GHz band with speeds up to 11 Mbit/s. While often the first widely adopted standard, it was not the first one published.
- IEEE 802.11g: Released in 2003. It operates in the 2.4 GHz band with speeds up to 54 Mbit/s.
Therefore, option D is the correct answer. Your selection of option B (802.11b) is a common mistake because 802.11b was the first to achieve massive commercial success, but 802.11 (the base standard) was technically published first.
