A network administrator is tasked with deploying a new wireless access point that needs to serve a large number of devices simultaneously, including IoT devices, and provide efficient bandwidth utilization to handle extensive multimedia streaming and data transfers. Keeping such requirements in mind, which wireless technology will best serve the organization's needs while ensuring low latency and power efficiency?
The correct answer is 802.11ax, as this technology, more widely known as WiFi 6, is tailored to operate efficiently in high-density scenarios such as those with numerous IoT devices. WiFi 6 features technologies like OFDMA and MU-MIMO, which offer substantial improvements in terms of supporting multiple devices, reducing latency, and power efficiency for devices, making it the most suitable option for the network administrator's requirements compared to the other listed technologies. 802.11ac, although an improvement over 802.11n, does not provide significant enhancements in high-density environments when compared to 802.11ax. Additionally, 802.11ad, while offering high throughput, is designed for ultra-short-range communication and would not suit the high-density, diverse-device requirement.
