Ultra Wide 320 MHz for WiFi 7

By admin Date of issue: Jul 14,2023

WiFi 7 (also known as the 802.11be standard) introduced ultra-wide 320 MHz channels as an important technical improvement. This means that in WLAN, larger spectrum bandwidth can be used to transmit data.

WiFi 7's ultra-wide 320 MHz channels are a technological improvement that allow WiFi networks to transmit data across a larger spectrum. Compared to the 160 MHz channels of previous WiFi standards, such as WiFi 6, it provides twice the bandwidth.

Imagine that there are multiple wireless access points (APs) in a WiFi 7 network, and they are respectively connected to WiFi 7 compatible devices. These devices can use ultra-wide 320 MHz channels for data transmission.

The concept of an ultra-wide 320 MHz channel is shown in the figure below:


In the diagram, 320 MHz channels are used to transmit data in the wireless network. Multiple APs connect to the device through this channel to provide higher data rates and capacity.

The introduction of ultra-wide 320 MHz channels enables WiFi 7 networks to provide greater bandwidth and faster speeds, which is very beneficial for handling high-bandwidth tasks and providing a seamless network experience. It also improves multi-user performance and improves the spectrum efficiency of the network.

It should be noted that the actual WiFi 7 network may have different configurations and device layouts, and the illustration here is only a conceptual description.

Increased Spectral Bandwidth:

The ultra-wide 320 MHz channel of WiFi 7 extends the transmission bandwidth to 320 MHz, doubling the bandwidth compared to previous WiFi standards such as the 160 MHz channel of WiFi 6. This means that more spectrum resources are available for WiFi networks, providing higher data transmission rates and capacities.

Higher Data Rates:

WiFi 7 enables higher data rates by using ultra-wide 320 MHz channels. It allows more data to be transferred in the same amount of time, providing faster download and upload speeds. This is great for working with large files, HD video streaming, and other high-bandwidth applications.

Multi-user performance improvements:

The ultra-wide 320 MHz channels also improve the multi-user performance of WiFi networks. It allows more data streams to be processed simultaneously, increasing the throughput and capacity of the network. This means that in a high-density user environment, more users can connect simultaneously and enjoy higher speeds and more stable connections.

low latency:

Ultra-wide 320 MHz channels help reduce network latency. By providing a larger data channel, data can be transmitted from the sender to the receiver more quickly, thereby reducing communication delays. This is important for latency-sensitive tasks such as real-time applications, online gaming, and video conferencing.

Spectrum utilization efficiency is improved:

Ultra-wide 320 MHz channels improve the spectrum efficiency of WiFi networks. It allows WiFi devices to transmit data in a larger spectrum range, reduces the waste of spectrum resources, and improves the overall spectrum utilization efficiency.

Note that in order to use ultra-wide 320 MHz channels, a correspondingly supported WiFi device and proper spectrum planning are required. In addition, interference from other wireless devices also needs to be fully considered and managed. The ultra-wide 320 MHz channel of WiFi 7 is an important technological advancement for the next generation of wireless networks, promising a faster and more reliable wireless connection experience.
