At start I helped in analyzing the throughput of 802.11g in dense environment, by conducting experiments at large class rooms, workshops etc. *Moving on to 802.11n, we conducted series of single client experiments using various clients. From the data collected, we see the drop in expected throughput. We explained this inconsistency by stating that 802.11n clients are not capable of handling high aggregation. Hence, we see drop in data rate as well as throughput.*This led to a paper publication in COMSNETS 2015 : “Usage of 802.11n in Practice: A Measurement Study”. Show less
