WiFi 7 Is Coming: What Sets It Apart from WiFi 6 and WiFi 6E

In the world of wireless technology, staying up-to-date is crucial. With the proliferation of smart devices and the increasing demand for faster and more reliable internet connections, the evolution of Wi-Fi is a topic of constant interest. WiFi 6, WiFi 6E, and now WiFi 7 are the latest generations of Wi-Fi technology. In this blog, we'll explore what sets WiFi 7 apart from its predecessors, WiFi 6 and WiFi 6E.

WiFi 6 (802.11ax):

  • Frequency Bands: WiFi 6 operates primarily in the 2.4 GHz and 5 GHz frequency bands.
  • Speed: It offers theoretical speeds of up to 9.6 Gbps.
  • Efficiency: WiFi 6 introduced technologies like OFDMA and MU-MIMO to improve the efficiency of data transmission and reception.
  • Coverage: The use of BSS coloring technology helps reduce interference and enhance signal range.
  • Interference: It provides better performance in crowded areas.


WiFi 6E (802.11ax Extended):

  • Frequency Bands: WiFi 6E expands into the 6 GHz frequency band in addition to the 2.4 GHz and 5 GHz bands.
  • Speed: It maintains the same theoretical speeds as WiFi 6, but the additional spectrum in the 6 GHz band reduces interference, leading to improved performance.
  • Coverage: The additional spectrum and channels allow for better coverage, especially in larger homes or offices.
  • Backward Compatibility: WiFi 6E is backward compatible with WiFi 6 and older devices.

WiFi 7 (802.11be):

  • Frequency Bands: WiFi 7 is expected to operate across a range of frequency bands, including 2.4 GHz, 5 GHz, and potentially the 6 GHz band as well.
  • Speed: Anticipated theoretical speeds are significantly faster, up to 30 Gbps, which is ideal for bandwidth-intensive applications like 8K streaming and augmented reality.
  • Reliability: WiFi 7 is expected to introduce advanced error correction and interference management techniques for a more reliable connection, even in crowded environments.
  • Power Efficiency: The technology aims to be more power-efficient, which will extend battery life for mobile devices and IoT devices.
  • Security: Enhanced security features are likely to be incorporated to protect against evolving cyber threats.
  • Device Density: WiFi 7 is designed to support a significantly higher number of devices in a network, catering to the expanding Internet of Things (IoT).

In summary, while WiFi 6 and WiFi 6E built upon the foundation of previous Wi-Fi standards, offering increased speed, efficiency, and coverage, WiFi 7 takes it a step further with even faster speeds, enhanced reliability, improved power efficiency, better security, and support for a higher number of devices. However, it's important to note that WiFi 7 is still under development, and it may take some time before it becomes widely available. In the meantime, WiFi 6 and WiFi 6E are excellent choices for high-performance wireless networking.
