The IEEE802.11ac standard of wireless networking operates in the 5GHz frequency range and offers higher data rates and improved performance compared to earlier standards. One of the key features of 802.11ac is channel bonding, which allows for the use of multiple channels simultaneously to increase the available bandwidth. In the 5GHz frequency range, channel bonding is typically achieved by combining adjacent 20 MHz channels into wider channels of up to 160 MHz. This provides a significant increase in available bandwidth, which can lead to faster data rates and improved overall network performance. As a result, channel bonding is an important technology for improving wireless network performance, and it is widely used in many applications, including video streaming, online gaming, and enterprise networks. In this research paper, multiple scenarios are examined, with different channel bandwidth configurations including (8x20, 4x40, 2x80, & 1x160 MHz), as well as (4x20, 2x40, & 1x80 MHz), and (2x20 & 1x40 MHz). The scenarios also vary in terms of MIMO spatial streams, with options for (1x1, 2x2, 4x4, and 8x8 SS). To simulate these scenarios, the network simulator (NS-3) version 3.37 is utilized. The simulation results show that when bonding (8x20, 4x20, and 2x20 MHz) is considered, the highest throughput and least amount of delay values are acquired. Specifically, for MIMO (8x8) SS and with respect to the Static Channel Bonding (SCB) (1x160, 1x80, and 1x40 MHz), the effect of DCB is more clarified specially when high number of nodes scenario (48) is used. The throughput values for the bondings (8x20, 4x20, & 2x20 MHz) are (4365, 1840, & 720 Mbps) respectively, compared to (3055, 982.4, and 378.5 Mbps) for 1x160, 1x80, and 1x40 MHz, and the delay values for (8x20, 4x20, & 2x20 MHz) are (0.0019, 0.0046, & 0.0117 Sec), compared to (0.0028, 0.0085, and 0.0222 Sec) for 1x160, 1x80, and 1x40 MHz.

Standard sieci bezprzewodowych IEEE802.11ac działa w zakresie czstotliwości 5 GHz i zapewnia wyższą szybkość transmisji danych oraz lepszą wydajność w porównaniu z wcześniejszymi standardami. Jedną z kluczowych cech standardu 802.11ac jest łączenie kanałów, które umożliwia jednoczesne korzystanie z wielu kanałów w celu zwiększenia dostępnej przepustowości. W zakresie częstotliwości 5 GHz łączenie kanałów jest zwykle osiągane poprzez łączenie sąsiednich kanałów 20 MHz w szersze kanały o szerokości do 160 MHz. Zapewnia to znaczny wzrost dostępnej przepustowości, co może prowadzić do wyższych szybkości przesyłania danych i poprawy ogólnej wydajności sieci. W rezultacie łączenie kanałów jest wazną technologią poprawiającą wydajność sieci bezprzewodowej i jest szeroko stosowane w wielu aplikacjach, w tym w strumieniowym przesyłaniu wideo, grach online i sieciach korporacyjnych. W tym artykule badawczym zbadano wiele scenariuszy z różnymi konfiguracjami przepustowości kanału, w tym (8x20, 4x40, 2x80, & 1x160 MHz), a tak że (4x20, 2x40, & 1x80 MHz) i (2x20 & 1x40 MHz) ). Scenariusze różnią się również pod względem strumieni przestrzennych MIMO, z opcjami dla (1x1, 2x2, 4x4 i 8x8 SS). Do symulacji tych scenariuszy wykorzystywany jest symulator sieci (NS-3) w wersji 3.37. Wyniki symulacji pokazują, ze przy uwzględnieniu łączenia (8x20, 4x20 i 2x20 MHz) uzyskuje się najwyższą przepustowość i najmniejsze wartości opóźnień. W szczególności dla MIMO (8x8) SS i w odniesieniu do Static Channel Bonding (SCB) (1x160, 1x80 i 1x40 MHz), efekt DCB jest bardziej klarowny, zwłaszcza gdy stosowany jest scenariusz dużej liczby węzłów (48). Wartości przepustowości dla wiązań (8x20, 4x20, & 2x20 MHz) wynoszą odpowiednio (4365, 1840, & 720 Mb/s) w porównaniu z (3055, 982.4 i 378.5 Mb/s) dla 1x160, 1x80 i 1x40 MHz oraz warto´ sci opóźnienia dla (8x20, 4x20, & 2x20 MHz) wynoszą (0.0019, 0.0046, & 0.0117 s), w porównaniu do (0.0028, 0.0085 i 0.0222 s) dla 1x160, 1x80 i 1x40 MHz.
