Performance Comparison Analysis Between IEEE 802.11a/b/g/n Standards
Now-a-days, in practical application scenario, with increasing demand of wireless LANs, higher data rates are required. Wireless Local Area Network (WLAN) is based on IEEE 802.11 standard and is also popular by the name as Wireless-Fidelity (Wi-Fi). The task groups within the 802.11 working group introduced few extensions to the original specifications. The well known extensions of 802.11 specifications are 802.11b, 802.11a, 802.11g and 802.11n. This paper provides the major differences between various IEEE 802.11 standards, their operation, interoperability and deployment constraints. In this paper, performances of IEEE 802.11a/b/g/n standards are explained.
