What is the difference between 802.11ac and 802.11ax?

In today's digitally connected culture, there is a greater need than ever for dependable, quick wireless internet. WiFi 5 (802.11ac) and WiFi 6 (802.11ax) are two crucial protocols that are at the forefront of technology, supporting our home networks as they advance. It's crucial to comprehend these standards since they affect the hardware needed for your home network, the features that may be utilized with it, and the WiFi's general performance. In this read, we will get a thorough idea about the 802.11ac and 802.11ax individually and also know the difference between them.

The Foundation: WiFi 5 (802.11ac)

Introduction to WiFi 5:

Around 2013, the fifth generation of wireless networking protocols, generally known as WiFi 5 or 802.11ac, was introduced. The WiFi Alliance created it with the main objective of achieving gigabit speeds, which could theoretically reach incredible rates of up to 3.5 Gbps in the perfect scenario. It included a variety of improvements that completely changed the wireless environment, making it a significant improvement over WiFi 4 (802.11n), its predecessor.

Speed and Performance:

WiFi 5's capacity to give unmatched speeds was one of its most notable qualities. It changed the way huge file downloads, online gaming, and streaming of high-definition video were done because of its ability to deliver rates of up to 3.5 Gbps. A more fluid and responsive internet experience was made possible by these quicker speeds.

Wider Frequency Channels:

WiFi 5 introduced wider WiFi frequency channels, enabling wireless devices to transmit and receive more data. This enhancement translated into a considerable boost in overall performance, particularly in environments with multiple connected devices.

MU-MIMO Technology:

MU-MIMO Technology, a groundbreaking feature that distinguished WiFi 5 from its predecessors, was the implementation of MU-MIMO (Multi-User, Multiple Input, Multiple Output) technology. MU-MIMO marked a significant leap in wireless networking capabilities by enabling routers to transmit data concurrently to multiple devices, thereby alleviating network congestion and vastly enhancing overall network efficiency. This technological advancement proved to be particularly advantageous in residences with a multitude of connected devices, all competing for limited bandwidth resources. With MU-MIMO, WiFi 5 introduced a more streamlined and equitable data distribution approach, significantly improving the wireless connectivity experience for users in diverse environments.

Exclusive Use of 5GHz Frequency:

Unlike its predecessor, WiFi 5 exclusively utilized the 5GHz wireless frequency. This shift was significant because it reduced interference from other devices using the crowded 2.4GHz spectrum, resulting in a more reliable and less congested connection.

The Next Frontier: WiFi 6 (802.11ax)

Introduction to WiFi 6:

WiFi 6, also known as 802.11ax, represents the latest and highest-performing WiFi standard available. It was introduced in late 2019, succeeding WiFi 5 (802.11ac). WiFi 6 was designed to push the boundaries of wireless technology even further, offering enhanced capabilities that address the growing demands of modern connectivity.

Unprecedented Speeds:

One of WiFi 6's standout features is its staggering speed capability, with potential speeds of up to 9.6 Gbps. This boost in speed makes WiFi 6 the ideal choice for bandwidth-intensive activities, including 4K streaming, virtual reality, and online gaming. It takes wireless performance to a whole new level.

Efficient Data Management:

WiFi 6 brings a revolution in data management, ensuring faster speeds even in congested environments. Optimizing the use of available channels minimizes interference and delivers consistent high-speed connections.

Dual-Band Support:

WiFi 6 supports both the 2.4GHz and 5GHz frequencies, as opposed to WiFi 5, which was primarily reliant on the 5GHz band. This dual-band compatibility makes sure that gadgets may connect to the best frequency, enabling quicker and more dependable internet access on both bands.

Targeted Wake Time (TWT):

WiFi 6 introduces an innovative feature called "Targeted Wake Time (TWT)." This technology enables routers to intelligently put WiFi connections to sleep when not in use, preserving the battery life of smartphones, laptops, and other connected devices. It's a game-changer for efficiency and energy conservation.

Enhanced Device Capacity:

Another remarkable feature of WiFi 6 is its ability to handle a significantly higher number of connected devices simultaneously. This means that your network can support more devices without experiencing additional latency or lag, making it perfect for smart homes and crowded public spaces.

Improved MU-MIMO Capacity:

WiFi 6 elevates the MU-MIMO capacity from 4x4 (WiFi 5) to 8x8. This means that even more data can be delivered simultaneously to multiple connected devices, further enhancing network efficiency.

Multi-Access Channels:

WiFi 6 offers multiple access channels, allowing one wireless channel to be divided into several sub-channels. This innovation enables more devices to connect at high speeds, making it particularly valuable in densely populated areas like hotels, airports, and stadiums.

Increased Speed and Efficiency:

In the realm of wireless networking, WiFi 6 continues to shine. It cleverly employs both the 2.4GHz and 5GHz bands, but its unique dual-band capacity opens up new horizons. This innovative approach guarantees that a larger number of devices within your network can enjoy accelerated streaming speeds and heightened efficiency. As a result, you'll experience significantly reduced lag times, ensuring a consistently stable and uninterrupted connection for all your online activities. This leap in performance is a testament to the remarkable capabilities of WiFi 6, making it an indispensable choice for modern connectivity demands.

The Verdict: WiFi 6's Superiority

In the debate of WiFi 5 vs. WiFi 6, it's clear that WiFi 6 takes the lead. Here's a breakdown of why WiFi 6 is the superior choice:

  • Next-Generation Technology: WiFi 6 represents the pinnacle of wireless technology, offering the latest advancements in connectivity.
  • Faster Speeds and Performance: With unparalleled speeds of up to 9.6 Gbps, WiFi 6 redefines what's possible in wireless performance. It's perfect for bandwidth-intensive activities and applications.
  • Increased Device Capacity: WiFi 6's ability to handle a greater number of connected devices without introducing latency or lag is a game-changer, especially in today's connected world.
  • Improved Frequency Band Performance: WiFi 6 optimizes performance across both the 2.4GHz and 5GHz bands, ensuring reliable and fast connectivity across the spectrum.
