Comprehensive Overview of the New Wi-Fi 7 Standard

Wi-Fi 7, officially termed as 802.11be Extremely High Throughput, has started making waves in the world of Internet technology, even before its official release scheduled in May 2024. This new Wi-Fi standard builds upon the groundwork laid by the prior Wi-Fi 6 and 6E standards. It promises faster and smoother connections for multiple devices, making it an attractive choice for manufacturers and consumers alike.

Understanding Wi-Fi 7

Wi-Fi 7 expands the bandwidth for Wi-Fi transmissions, supports the 6 GHz frequency, and utilizes 320 MHz channels. Additionally, this new standard facilitates Orthogonal Frequency-Division Multiplexing (OFDM) and BSS Coloring. Both these functions ensure efficient data transmission without delay, even in vast networks. The transition from previous Wi-Fi standards to Wi-Fi 7, thus, promises better antennas, more powerful hardware, and faster speeds.

The Need For Wi-Fi 7

In recent times, an increasing number of devices, from mobile phones to PCs, smart home devices, TVs, and audio systems, depend on robust and speedy wireless connectivity. With this dependency, the need for greater bandwidth and uninterrupted internet connections has become paramount. Wi-Fi 7 emerges as the solution to these demands.

Wi-Fi 7 Tools and Innovations

The introduction of Wi-Fi 7 comes with a set of innovative tools. It offers wider radio channels, quicker and more MIMO streams, and multiple features ensuring simultaneous transmission without device interference. A significant highlight is the Multi-Link Operation (MLO), which enables simultaneous data transmission over different frequencies, augmenting the stability and speed of Wi-Fi connections.

The Way To Wi-Fi 7

To experience Wi-Fi 7 and its myriad advancements, it is necessary to equip oneself with new hardware. The available choices of routers and repeaters with Wi-Fi 7, notebooks, and smartphones with suitable radio modules will broaden by the end of 2023, offering consumers a wide array of options.

The Future of Wi-Fi

Going beyond Wi-Fi 7, plans and discussions for its successors have already started. Developments are being made for the introduction of Wi-Fi Sensing, the 802.11bf standard, aimed at evaluating Wi-Fi signals to detect human presence and movement in a room. This fascinating technology opens the door to Wi-Fi based alarm systems and smart home devices.
