As a telecommunications expert with a background in wireless communication technologies, I can provide you with a detailed explanation regarding the speed of Wi-Fi.
When discussing Wi-Fi speeds, it's essential to consider the standard being used, as different standards have different maximum theoretical speeds. The 802.11ac standard, for instance, is known for offering higher speeds compared to its predecessors, such as 802.11b/g/n.
The theoretical maximum speed of 802.11ac, as you mentioned, is quite impressive. It can utilize up to eight 160MHz channels with 256-QAM modulation, where each channel can deliver speeds of up to 866.7Mbps. When combined, these channels can theoretically achieve a total speed of around 6,933Mbps, which is just under 7Gbps. This translates to a transfer rate of approximately 900 megabytes per second. It's worth noting that this speed is significantly higher than what can be achieved through a SATA 3 interface, which is commonly used for data storage devices.
However, it's crucial to understand that these are theoretical maximum speeds, and actual Wi-Fi speeds can vary significantly based on several factors. These factors include the distance from the router, interference from other wireless devices, the number of devices connected to the network, and the capabilities of the client devices (such as laptops, smartphones, etc.). Additionally, network congestion and the quality of the Wi-Fi signal can also impact the speed.
In practical scenarios, users typically experience speeds that are a fraction of the theoretical maximum. This is because real-world conditions rarely allow for the optimal conditions required to achieve maximum speeds. For instance, walls, furniture, and other physical obstructions can weaken the Wi-Fi signal, leading to slower speeds. Moreover, if multiple devices are connected and sharing the bandwidth, the available speed for each device will be divided accordingly.
Another important consideration is the Wi-Fi channel width. While 802.11ac can support 160MHz channels, not all devices or routers may support this width, and some may operate on narrower channels, such as 80MHz or 40MHz. This will also affect the achievable speed.
Furthermore, the quality of the Wi-Fi router and the client devices plays a significant role. High-quality routers with multiple antennas and advanced features like beamforming can provide better coverage and speed. Similarly, client devices with better Wi-Fi capabilities will be able to connect at higher speeds.
In summary, while the theoretical maximum speed of Wi-Fi, particularly the 802.11ac standard, can be quite high, the actual speed experienced by users will depend on a variety of factors. It's always a good idea to consider these factors when evaluating the performance of a Wi-Fi network.

The theoretical max speed of 802.11ac is eight 160MHz 256-QAM channels, each of which are capable of 866.7Mbps, for a total of 6,933Mbps, or just shy of 7Gbps. That's a transfer rate of 900 megabytes per second -- more than you can squeeze down a SATA 3 link.Aug 22, 2016
