چکیده

We examine the peak performance of an 802.11n system with respect to the achievable throughput and we decompose the gains observed due to the various PHY/MAC layer features offered from 802.11n. Our results show that while the MIMO PHY and channel bonding offered from 802.11n increase the PHY data rate, packet aggregation and block acknowledgment are required to achieve throughput closer to the latter.

Two Antennas are Better than One: A Measurement Study of 802.11n

We present a measurement study of how well 802.11n works in practice. Our goal is to understand the performance impact of the multiple antenna (spatial) techniques that are the key new capability of 802.11n. We experiment with a 10 node indoor testbed equipped with commodity Intel 802.11n NICs that have three antennas, i.e., 3x3 MIMO, and lowlevel instrumentation to let us to measure RF channel...

NEW: A Channel Management Strategy for IEEE 802.11n

IEEE 802.11n is a newly emerging wireless standard which, relative to former 802.11 protocols, such as 802.11a/b/g, has a number of new mechanisms that enable multifold increases in transmission speeds. These new mechanisms include multipleinput-multiple-output (MIMO) transmission schemes as well as the option for channel bonding two 20MHz channels into a single 40MHz channel. Furthermore, 802....

T-SIMn: Towards a Framework for the Trace-Based Simulation of 802.11n Networks

With billions of WiFi devices now in use, and growing, combined with the rising popularity of high-bandwidth applications, such as streaming video, demands on WiFi networks continue to rise. To increase performance for end users the 802.11n WiFi standard introduces several new features that increase Physical Layer Data Rates (PLDRs). However, the rates are less robust (i.e., more prone error). ...

Analyzing the basic performance of IEEE802.11g/n

This paper describes a new standardization effort – IEEE 802.11n, and its comparison with legacy standard. In this paper we present the results of a measurement campaign evaluating the performance of both standards IEEE802.11g/n. We concentrate our evaluation on wireless communication in the outdoor scenario. We found that distance, throughput and signal/noise ratio characterize the basic perfo...
