A small business is setting up a wireless network to ensure high data transmission rates for video conferencing and file transfers. The network administrator is considering different Wi-Fi technologies. Which technology should be chosen to support higher bandwidth and shorter range communications?
802.11ac, also known as Wi-Fi 5, operates exclusively in the 5 GHz frequency band. This band is typically less crowded than the 2.4 GHz band and allows for wider channels, enabling much higher data rates (up to several Gbps) that are ideal for bandwidth-intensive tasks like video conferencing and large file transfers. The 5 GHz frequency has a shorter effective range compared to 2.4 GHz, which aligns with the scenario's requirements. The other options are less suitable: 802.11b and 802.11g use the 2.4 GHz band and have significantly lower maximum speeds (11 Mbps and 54 Mbps, respectively). 802.11a uses the 5 GHz band but is an older standard with a maximum speed of only 54 Mbps.
