What does the number next to the WiFi symbol mean?
The number next to the WiFi symbol, often seen as a 6, represents the WiFi standard being used by your device. This number is an indicator of the WiFi generation or version that your device is currently connected to. WiFi standards have evolved over the years, with each new generation offering faster speeds, better performance, and improved reliability.
In the case of the number 6, it represents WiFi 6, which is the sixth generation of WiFi. WiFi 6 offers several improvements over its predecessors, including faster speeds, better performance in crowded environments, and improved power efficiency. WiFi 6 is also known as 802.11ax, which is the technical name for this WiFi standard.
What are the different WiFi standards?
There have been several WiFi standards over the years, each with its own set of features and improvements. The most common WiFi standards include WiFi 4 (802.11n), WiFi 5 (802.11ac), and WiFi 6 (802.11ax). WiFi 4 was introduced in 2009 and offered speeds of up to 600 Mbps. WiFi 5 was introduced in 2013 and offered speeds of up to 3.5 Gbps. WiFi 6, the latest standard, was introduced in 2019 and offers speeds of up to 9.6 Gbps.
Each WiFi standard has its own set of features and improvements, and devices can only connect to WiFi networks that support the same standard. For example, a device that only supports WiFi 4 cannot connect to a WiFi 6 network. However, most modern devices support multiple WiFi standards, allowing them to connect to different types of WiFi networks.
How does WiFi 6 improve performance?
WiFi 6 improves performance in several ways. One of the main improvements is the use of orthogonal frequency-division multiple access (OFDMA) technology, which allows multiple devices to share the same channel. This improves performance in crowded environments, such as coffee shops or airports, where many devices are competing for bandwidth. WiFi 6 also uses a technology called multi-user multiple input multiple output (MU-MIMO), which allows the router to serve multiple devices at the same time.
Another improvement in WiFi 6 is the use of beamforming technology, which allows the router to focus its signal on specific devices. This improves the signal strength and reduces interference, resulting in faster speeds and better performance.
