WiFi 7 key features and benefits
5x faster speeds
than WiFi 6E
WiFi 7 increases maximum speeds from 9.6 Gbps to a stunning 46 Gbps, so you can take full advantage of today’s ultra-fast internet plans with Gigabit-plus performance on your devices.
2x maximum bandwidth
320 MHz high-capacity channels
New, ultra-wide bandwidth means double the speed to your devices. WiFi 7 smart phones can get speeds up to 5 Gbps. This opens up exciting new possibilities for AR and VR applications. 1.2 GHz spectrum in 6 GHz band makes 320 MHz ultra-wide band possible and also allows for more routers to operate in congested neighborhoods without stepping on each other.
Significantly lower latency
for real-time responsiveness
Latency has a noticeable effect on real-time activities like gaming and video conferencing. WiFi 7 dramatically upgrades current gen experiences and opens the door for immersive next gen AR and VR.
20% more data transmission
with 4096-QAM modulation
Modulation, simply put, is the process of converting data into WiFi radio waves. A jump from 10-bit to 12-bit data modulation packs in 20% more data at a time for crystal-clear video streaming, Zoom calls and more.
WiFi 7带来了哪些创新?
MULTI-LINK OPERATION
The power of two
WiFi 7 taps both 6 GHz and 5 GHz WiFi bands at once to avoid network traffic and keep you connected if you move out of range of one band. This feature, called multi-link operation, also enables devices to simultaneously send and receive data across both WiFi bands, increasing throughput.
PREAMBLE PUNCTURING
Outsmart WiFi interference
Did you know your neighbors' WiFi might be slowing your network down? With previous versions of WiFi, any channels with interference become unavailable. Preamble puncturing allows your WiFi to slice off part of a channel to transmit your data, if the interference isn’t occupying the entire channel, greatly reducing network congestion.
