Wi-Fi 5 vs. Wi-Fi 6: What’s the Difference?

Wi-Fi 5 and Wi-Fi 6 wireless technologies have quickly become ubiquitous today, with users often favoring one over the other depending on their requirements. However, selecting the proper Wi-Fi standard is crucial to avoiding potential losses and ensuring optimal performance.

Let’s examine some key differences between Wi-Fi 5 and Wi-Fi 6 so we can assist you with making informed decisions.

Maximum Data Rate

The maximum data rate is integral when comparing Wi-Fi 5 and Wi-Fi 6. Wi-Fi 5, or 802.11ac, supports data rates up to 6.9 Gbps. On the other hand, Wi-Fi 6, also known as 802.11ax, significantly outpaces Wi-Fi 5 with maximum data rates of up to 9.6 Gbps.

Consequently, increased data rates result in faster wireless connectivity, thus enabling quicker file transfers, smoother streaming sessions, and enhanced overall network performance. Furthermore, a higher data rate assists in handling data-intensive tasks. These include 4K/8K video streaming, online gaming, and extensive file sharing, which can all be managed seamlessly using this solution.

Additionally, network optimization improves network efficiency and reduces congestion in environments with multiple connected devices.

Battery Life and Efficiency

While Wi-Fi 5 and Wi-Fi 6 standards seek to optimize power usage, Wi-Fi 6 introduces several enhancements designed to boost battery performance and optimize the user experience.

Wi-Fi 6 introduces Target Wake Time (TWT), enabling devices to schedule and synchronize their wake-up times. Consequently, this feature can significantly extend battery life by decreasing how often devices transmit and receive data, thus decreasing power usage.

Significantly, the benefit of reduced power consumption for users includes prolonged device usage without frequent charging sessions. This benefit holds especially for portable devices like smartphones, tablets, and IoT devices that can run for extended periods on one charge.

Furthermore, Wi-Fi 6’s enhanced power efficiency also creates a greener and more sustainable environment by decreasing energy consumption.

Frequency Bands

Wi-Fi 5 operates exclusively within the 5 GHz frequency band, while Wi-Fi 6 supports both 2.4 and 5 GHz frequency bands.

On the one hand, Wi-Fi 5 employs its primary frequency band of 5 GHz to deliver faster speeds and improved throughput, and reduced interference. Accordingly, these devices feature higher data rates, making them perfect for high bandwidth applications such as streaming HD videos or online gaming.

On the other hand, Wi-Fi 6 supports 5 GHz and 2.4 GHz frequency bands, expanding Wi-Fi’s support. Consequently, this addition assists in achieving excellent coverage and better-enhanced penetration through walls and obstacles.

Additionally, this inclusion makes Wi-Fi 6 ideal for expansive spaces or environments with multiple obstacles that might interfere with signal reception. Differences in frequency bands have serious ramifications for the compatibility and performance of devices.

For instance, devices compatible with Wi-Fi 5 and 6 can take advantage of the wider frequency spectrum offered by Wi-Fi 6. However, older devices limited only to supporting 5 GHz may not work with Wi-Fi 6 networks operating on 2.4 GHz channels.

Modulation Scheme

Wi-Fi 5 uses the 256-QAM (Quadrature Amplitude Modulation) modulation scheme, while Wi-Fi 6 introduces an advanced modulation method known as 1024-QAM for modulation purposes. Generally, modulation schemes determine how data are encoded and transmitted across wireless channels.

To start with, Wi-Fi 6 devices with higher-order modulation schemes, like 1024-QAM, can transmit more data per symbol for increased data throughput and improved network performance. Thus, Wi-Fi 6 provides higher data transfer rates compared to Wi-Fi 5.

Additionally, the Wi-Fi 6’s adoption of 1024-QAM technology significantly increases its network’s transmission speed and capacity. However, the 1024-QAM’s benefits only become evident if the router and the client device support this modulation scheme.

If the router or client device only supports 256-QAM, its benefits may not be fully exploited.

While Wi-Fi 6 is the newest standard, Wi-Fi 5 still has its widespread uses.

Security Protocols

Wi-Fi 5 supports WPA, and WPA2 protocols, while Wi-Fi 6 adds the support to accommodate WPA3. Specifically, WPA3 is the latest and most advanced security protocol designed to increase wireless network security.

In addition, WPA3 features superior encryption algorithms and provides increased protection from potential security vulnerabilities compared to WPA2. Plus, WPA3 adds features like individual data encryption and stronger password-based authentication to make it more resistant to attacks.

Thus, Wi-Fi 6 networks that support WPA3 add a layer of protection, helping ensure user data remains protected. However, to maximize WPA3 benefits, router and client devices must support it.

Access Technology

Wi-Fi 5 employs Orthogonal Frequency Division Multiplexing (OFDM), while Wi-Fi 6 utilizes Orthogonal Frequency Division Multiple Access (OFDMA).

On the one hand, with OFDM technology in Wi-Fi 5, available frequencies are partitioned into multiple subcarriers that do carry data simultaneously. But with OFDMA technology in Wi-Fi 6, subcarriers are further divided into smaller resource units called Resource Units (RUs).

However, these resource units (RUs) can be assigned simultaneously to multiple devices for maximum utilization of bandwidth resources. Therefore, by adopting OFDMA technology, Wi-Fi 6 enables improved multi-user performance, particularly within dense network environments.

In addition, OFDMA technologies allow simultaneous data transmission across multiple devices, increasing network capacity while decreasing latency. Ultimately, this can be particularly advantageous in situations with numerous connected devices, like public spaces.
