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?
802.11g
802.11b
802.11ac
802.11a
802.11ac supports dual-band wireless technology that allows for higher data rates (up to several Gbps) and operates exclusively in the 5 GHz frequency band, suitable for applications requiring higher bandwidth like HD video streaming and high-speed file transfer. The other options, although useful in various contexts, offer lower data rates and operate at 2.4 GHz (except for 802.11a, which uses 5 GHz but offers lower throughput than 802.11ac).
