A small business has recently moved into an office space with multiple wireless networks. The IT consultant is asked to establish a wireless network that minimizes interference from other networks and provides faster data throughput for the office's video-conferencing needs. Which wireless standard would be MOST appropriate for the consultant to use in this scenario?
802.11ac, also known as Wi-Fi 5, operates solely in the 5 GHz band, which is typically less congested than 2.4 GHz. It also supports wider channel widths (80 MHz/160 MHz) and higher-order modulation schemes, giving it theoretical multi-station speeds well above 1 Gbps. These attributes make 802.11ac the best choice for high-bandwidth, real-time applications such as video conferencing in crowded RF environments. By comparison, 802.11b and 802.11g are limited to the 2.4 GHz band with maximum data rates of 11 Mbps and 54 Mbps, respectively, while 802.11n can use 5 GHz but caps out at 600 Mbps and narrower 40 MHz channels.
