При этом разница между возможностями обслуживания мультисервисного трафика по технологиям IEEE 802.11n и IEEE 802.11ac несущественна, а выигрыш от изменения защитного интервала может достигать 10 % пропускной способности сети. Исследование проведено на имитационной модели и натурной сети.</p></abstract><trans-abstract xml:lang="en"><p>The article shows that the type of traffic, bandwidth and guard interval in IEEE 802.11 technologies have a minor effect on the quality of service indicators. At the same time, the difference between the multi-service traffic service capabilities between IEEE 802.11n and IEEE 802.11ac is insignificant, and the gain from changing the guard interval can reach 10 % of network bandwidth. The study was conducted on a model and a real-life network.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>защитный интервал</kwd><kwd>показатели QoS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>IEEE</kwd><kwd>Wi-Fi</kwd><kwd>Guard Interval</kwd><kwd>QoS Parameters</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Осколков И.
