Defining WiFi and How it Works

Before we get into the nitty-gritty of the different WiFi standards, let’s first briefly understand what WiFi is and how it enables wireless connectivity.

WiFi or Wireless Fidelity is a technology that allows internet connection over a wireless signal between a router and compatible devices like laptops, smartphones, smart TVs, etc. The router connects to the internet via a wired connection and creates a small wireless network to beam the signal to connected devices using radio frequencies.

Devices can connect to WiFi from within a specified range, which is determined by the strength of the router. Newer versions of WiFi allow faster data transfer over wider ranges. Devices must have compatible WiFi chipsets to be able to decode the wireless signal and access the internet.

Now let’s look at the different generations of WiFi and their technical specifications.

Introducing WiFi 5, WiFi 6, and WiFi 6E

WiFi technology has seen several upgrades over the years, with each major version bringing significant improvements in network speeds, connectivity, and features. Here is a brief overview of the newest WiFi generations:

  • WiFi 5 – Also known as 802.11ac, WiFi 5 was introduced in 2014 as a successor to 802.11n (WiFi 4). It operates on the 5 GHz frequency band and has a maximum theoretical transfer speed of 3.5 Gbps. Key features include Multi-User MIMO (MU-MIMO) and 256 QAM modulation.
  • WiFi 6 – Released in 2019, WiFi 6 or 802.11ax offers higher overall throughput compared to WiFi 5. It operates on both 2.4 GHz and 5 GHz bands and supports peak speeds up to 9.6 Gbps. Key enhancements include Orthogonal Frequency Division Multiple Access (OFDMA) and Target Wake Time (TWT).
  • WiFi 6E – The newest WiFi version approved in 2020, WiFi 6E, has all the capabilities of WiFi 6 with the additional feature of operating on the new 6 GHz frequency band. This results in faster speeds, lower latency, and reduced congestion.

Now let’s do a deep dive into what sets each of these advanced WiFi standards apart.

Deep Dive into WiFi Generations – Wi-Fi 5: Faster Speeds on the 5GHz Band

Introduced in 2014, WiFi 5 represented a significant upgrade from the previous 802.11n standard. With 802.11ac, WiFi technology graduated to the 5 GHz frequency band from the more crowded 2.4 GHz spectrum. This provided two key advantages:

  • Higher Bandwidth – The 5 GHz band has more available channels compared to 2.4 GHz, allowing 80 and 160 MHz channel widths and, consequently, higher throughput.
  • Less Interference – The 5 GHz band has less interference from other devices like microwaves, Bluetooth, etc. This ensured more reliable connections.

WiFi 5 has a maximum theoretical data transfer rate of 3.5 Gbps, a huge jump from WiFi 4’s 600 Mbps. However, actual real-world speeds range from 433 Mbps to 1 Gbps.

Some key features of WiFi 5 include:

  • MU-MIMO (Multi-User Multiple Input Multiple Output) – Allows simultaneous data transmission to multiple devices instead of one at a time.
  • 256 QAM (Quadrature Amplitude Modulation) – More efficient data encoding to transmit more data over the same bandwidth.

Despite the faster speeds, WiFi 5 has some limitations that impact the experience:

  • Only operates on 5 GHz band – Can cause issues with legacy 2.4 GHz devices.
  • Susceptible to congestion – Performance deteriorates in high-density environments as devices have to share bandwidth.

Overall, WiFi 5 is great for streaming 4K video, online gaming, and handling multiple connected devices in a small to medium-sized home or office.

If you’re curious about the practical implications of internet speeds, the below posts will provide a comprehensive analysis.

Wi-Fi 6: Blazing Fast Speeds + Efficient Performance

WiFi 6 or 802.11ax aims to build upon the strengths of WiFi 5 and further enhance overall performance. Introduced in 2019, it brings higher network speeds along with advanced features to improve capacity and efficiency. Here are some standout improvements:

  • Faster top speed – Theoretical maximum speed of 9.6 Gbps, nearly 3x faster than WiFi 5. Real-world performance ranges from 1.2 Gbps to 4 Gbps.
  • Dual-band support – Operates on both 2.4 GHz and 5 GHz frequencies for wider device compatibility.
  • OFDMA (Orthogonal Frequency Division Multiple Access) – Allows more devices to share channels efficiently without congestion.
  • TWT (Target Wake Time) – Schedules transmissions for specific devices to improve battery life.
  • 1024 QAM – Increased to 1024 QAM from 256 QAM for 33% faster data rates.

These enhancements make WiFi 6 ideal for environments with many connected devices like corporate offices, college campuses, and even smart homes. Even if devices can’t match the top WiFi 6 speed, they will experience significantly better network performance.

Some key benefits include:

  • Up to 4x increased network capacity compared to WiFi 5.
  • Minimal congestion issues even with many active connections.
  • Longer battery life for devices through TWT.
  • Seamless streaming, gaming, and connectivity for all users.

With widespread adoption, WiFi 6 brings us closer to the goal of flawless wireless connectivity in any environment.

WiFi 6E: Unleashing the 6 GHz Spectrum

The newest WiFi standard – WiFi 6E offers all the capabilities of WiFi 6 with one major additional benefit – access to the 6 GHz frequency band. Approved in 2020, this is the biggest development in WiFi technology in over 20 years.

The key advantages of tapping into the 6 GHz spectrum are:

  • More available bandwidth – Up to 7 additional 160 MHz channels for blazing fast speeds.
  • Reduced congestion – Less interference and clutter even in very dense, high-usage environments.
  • Lower latency – Up to 2-3x faster response times for time-sensitive uses like AR/VR and competitive gaming.
  • Backward compatibility – WiFi 6E routers maintain compatibility with legacy 2.4 GHz and 5 GHz devices.

In essence, WiFi 6E provides a kind of “express lane” for supported devices to access superfast unfettered connections. This makes it ideal for bandwidth-heavy applications:

  • 4K/8K video streaming – Multiple flawless streams without any lag or buffering.
  • VR gaming – Truly immersive experience without motion sickness.
  • Smart homes – Support dozens of connected IoT devices securely.

Device Compatibility and Upgrading Considerations

When considering an upgrade to WiFi 5, WiFi 6 or WiFi 6E, an important factor is device compatibility. Let’s look at some key points:

  • WiFi 5 is compatible with 802.11ac and some 802.11n devices.
  • WiFi 6 maintains backward compatibility with 802.11ac and 802.11n on the 5 GHz band.
  • WiFi 6E routers are backward compatible with WiFi 6, WiFi 5, and WiFi 4 devices.

However, to enjoy the full speeds and features offered by any WiFi version, your devices need compatible network adapters:

  • Laptops – Most modern laptops have chips supporting WiFi 5 and WiFi 6. For WiFi 6E, you may need to upgrade the network card.
  • Smartphones – Android phones and iPhones from the last 2-3 years generally support WiFi 5 and 6. Only the latest models offer WiFi 6E.
