Introduction to Wifi 7

WiFi 7 is the next potential wireless network version is expected, known by the technical title IEEE 802.11be. This indicates an addition to the original 802.11 WiFi standard.  

What is WiFi? It is a wireless protocol allowing devices to transmit and receive data via an Internet connection using frequency waves.

What kind of wave is WiFi? Two frequency waves are available, 2.4 GHz and 5 GHz, depending on the amount of transmitted data.

How does WiFi 7 work?

The three bands that Wi-Fi 7 uses are still 2.4GHz, 5GHz, and 6GHz, the same as WiFi 6E. So why is Wi-Fi 7 such an improvement? 

The key is to use wider channels. The 6-GHz band's channel capacity is doubled by Wi-Fi 7, increasing from 160MHz to 320MHz. 

Multi-Link Operation (MLO) is Wi-Fi 7's other major advancement. Wi-Fi 6 and 6E allowed devices to connect to several bands simultaneously, although only one band could be used at a time. 

Meanwhile, Wi-Fi 7 devices may connect to two bands concurrently thanks to MLO. Not only does this lead to increased dependability and ultra-low latency, but it also produces quicker speeds.

Wifi 7 Features 

Large Bandwidth 

To achieve a maximum throughput of 30Gbps, wifi 7 supports the 6GHz frequency band and extends new bandwidth modes (up to 320MHz).

Backward Compatibility

The wifi 7  provides backward compatibility with devices in the 2.4GHz, 5GHz, and 6GHz bands. This means users don't need a whole new device or hardware to connect to a router that supports wifi 7.

Multi-Link Mechanism

Wifi 7 also provides MultiLink operation (MLO). Load balancing and aggregation combine multiple channels at different frequencies for incredible performance. 

This means that wifi 7 routers can use all available bands and channels to speed up connections and avoid heavily interfering bands.

Higher-Order 4096-QAM

Wifi 7 also features 4096 quadrature amplitude modulation (QAM technology) to increase the number of data per hertz.

Lower Latency 

The Draft WiFi7 specification aims to increase the reliability and reduce the latency of time-sensitive networks or TSNs required for cloud computing and gaming.

Wifi 7 Benefits 

Supersonic Speed 

Wifi 7 standard will be possible to connect more devices to the network without interfering with the superior data speed. You will see this important benefit through a wifi speed test with an available wifi 7 next time. 

High Throughput 

In addition to supersonic speeds, wifi 7 also offers high throughput. This technology enables applications to achieve high data rates in real-time. 

This is especially important for augmented reality, virtual reality, games, and telecommuting services.

Multiple Device Connection

The total bandwidth of wifi 7 ranges from 6 to 7 channels, which speeds up data exchange between different devices on the network. Another advantage here is connecting more devices without affecting the transmission speed.

WiFi 7 vs Previous Generations

While WiFi 6 did offer 37% higher speeds, the impact was not as great as WiFi 5's 10-fold rate rise. The initial goal of the WiFi 6 project was efficiency improvements rather than higher data speeds, which explained the discrepancy. 

Conversely, WiFi 7 is built for a generation of increased throughput.

With a throughput 480% higher than previous generations, WiFi 7 achieves incredible throughput gains. A WiFi 7 router gives your entire house access to the newest internet experiences because of its backward compatibility.

Frequently Asked Questions (FAQs)
What is the difference between WiFi 6 and 7?
Wi-Fi 6 has a channel bandwidth that spans from 20 to 160 MHz. Wi-Fi 7, on the other hand, gives a maximum width of 320 MHz and twice the channel width.
Why is Wi-Fi 7 so fast?
Each WiFi band operates in smaller bands of 20/40/80/160MHz MHz for connecting to individual devices. Also, WiFi 7 doubles the bandwidth to 320MHz.
Is Wi-Fi 7 better than ethernet?
Although Wi-Fi 7's maximum theoretical speed is 46 Gbps, other estimates put real-world speeds much lower—around 6 Gbps—which is still significantly faster than Gigabit Ethernet.

Conclusion 

You’ve learned more about what is wifi 7 and how superior it is to advance the Internet network.  
Wifi 7 continues to expand wifi availability, cost-effectively forwarding most wireless traffic in business, public, and private environments. It will also further improve the efficiency of using valuable network resources.
