Long-distance WiFi networks are a cost-effective means for providing Internet connectivity in developing regions. In these regions, providing support for real-time applications is considered an important requirement. Unlike prior works, this paper studies the effectiveness of features (e.g., frame aggregation and channel bonding) of 802.11n/ac in improving the performance of long-distance WiFi links as well as their ability to support real-time applications. Towards this end, we established a 7.1 km link using commodity 802.11n equipment. Our results yielded a throughput of up to 36 Mbps by only changing 802.11 parameter values. In addition, we show that our setup also meets the delay and jitter requirements of real-time applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
