Wireless Fidelity (WiFi) networks have gained unprecedented growth in recent years and have played an important role in the popularity of wireless VoIP. IEEE 802.11n is the most widely used WiFi standard today. Transmission Opportunity (TXOP) and Frame Aggregation (FA) are two important Medium Access Control (MAC) Layer enhancements provided by IEEE 802.11n(More)
IEEE 802.11ac is an emerging standard that operates in 5GHz frequency band and provides high data rate as compared to IEEE 802.11n. In this paper we carry out experiments in a real indoor environment and quantify the gain in average throughput provided by IEEE 802.11ac compared to IEEE 802.11n in the presence of interference caused by other IEEE 802.11n(More)
