What is the difference between WiFi 5 and WiFi 6? Which one should you choose to use to be the most suitable?


WiFi is the most commonly used wireless communication technology. To receive and send information via the internet around the world

The new wireless communications technology was created by Dr. John O’Sullivan, known as the “Father of WiFi,” who worked for CSIRO in the 1990s Wireless Ethernet Compatibility Alliance (now called the Wi-Fi Alliance).

“Wi-Fi” was only a trademark claimed by the Wi-Fi Alliance in 1999.

WiFi is a wireless network technology. It is a two-way communication between the router and the device. The two machines must have a radio transmitter and receiver to communicate with each other by transmitting signals over radio frequencies (2.4 GHz or 5 GHz).

The router or modem receives the signal from the service provider. If the internet from the service provider’s router is slow or not enough It is necessary to have an additional signal amplifier.

So do you need to buy more signal amplifiers?

First, figure out your network needs and the number of devices in your home connected to the internet. 

Note: If the devices in your home support Wi-Fi 6, you will need a WiFi 6 router.

The next step is to check how much area you want to cover. The enviroment plays a huge role in Internet coverage

Each router has different performance. The 2.4GHz range is typically around 65 sq. ft. (or 20 meters) and the 5GHz range is 49 sq. ft. (15 meters).

If the router is not fast enough or does not cover the desired area, purchasing additional One Mesh or Deco Mesh WiFi will help cover even more areas.

  1. One Mesh is a cost-effective mesh network that integrates with existing TP-Link devices.
  2. Deco Mesh is a whole-home Mesh WiFi system.

What is the difference between WiFi 5 and WiFi 6?

The basis of WiFi 5 is 802.11ac, which uses only the 5 GHz frequency band. Compared to 802.11n, 802.11ac has wider channels, higher modulation, and improved MIMO technology—MU-MIMO. WiFi 6, or 802.11ax, is the newest technology created in response to the increasing number of connected devices. Wi-Fi 6 builds on 802.11ac and is designed to improve speed. Increase full efficiency Both sending and receiving messages are faster. Reducing network congestion through more efficient data modulation such as OFDMA and 1024-QAM, 802.11ax also adds support for Uplink MU-MIMO (UL MU-MIMO).

What is Mesh WiFi?

Mesh WiFi is a Wi-Fi system that will allow you to use a single WiFi name to cover your entire home. Shared work between individual nodes works to create a unified network. There are interesting features such as One name can be used for the whole house, self-repair system Signal routing adjustment for a stable network and also install and manage through the application

Mesh WiFi is designed to provide continuous WiFi coverage to every inch of your home.

There are 4 models of Mesh WiFi that support WiFi 6: Deco X20, Deco X60 and Deco X90.

Deco X20 Dual Band AX1800 (1,200Mbps + 574Mbps) that comes with WiFi 6 technology besides covering the entire house It also reduces latency, making it fun to play games or videos without interruption.

  1. The Deco X20 is a Dual Band AX1800 (1,200Mbps + 574Mbps) system that comes with WiFi 6 technology. In addition to providing complete coverage throughout the home, it also reduces latency, ensuring an enjoyable experience for gaming or video streaming without interruptions.
  2. The Deco X20-4G, a Dual Band AX1800 (1,200Mbps + 574Mbps) system, provides WiFi 6 Mesh coverage through access to 4G+ CAT6. Not only does it cover the entire home, but it also reduces latency, ensuring a seamless and enjoyable experience for gaming or video streaming without interruptions.
  3. The Deco X60 is a Dual Band AX3000 (2,402Mbps + 574Mbps) system equipped with WiFi 6 technology. It establishes a more efficient network with an average data transmission rate that is four times higher, enhancing the overall performance. This results in a seamless and enjoyable experience for gaming or video streaming without interruptions.
  • The Deco X90 is a Tri-Band AX6600 system with three frequency bands, featuring WiFi 6 technology and AI-Driven Mesh. It leverages AI to learn about the environment and adjusts signals accordingly, ensuring optimal coverage. This extends strong signals to every area within the home.
