You no longer have to experience Wi-Fi drops or slowdowns when gaming online or streaming your favorite movies, no matter how many devices are on your network. Wi-Fi 6 is the epitome of internet connectivity. Here are the top reasons to upgrade to this Wi-Fi standard:
Breakneck Speeds
Wi-Fi 6 supports breakneck speeds and fast data transmission rates with every connection. It delivers higher data throughput than all other Wi-Fi generations, and it is 40% faster than its predecessor, Wi-Fi 5. Maximum link rates reach 10000 Mbps (10 Gbps), making it the fastest Wi-Fi specification globally. Thanks to these incredible speeds, you can play online games and stream 4K UHD movies without issues.
Reduced Latency
Latency refers to the time delay in transmitting data from one point to another. Many wireless networks experience some degree of latency during data transmission. The delay is usually unnoticeable since it does take more than a few milliseconds.
The average latency of Wi-Fi 6 is 2 milliseconds. This Wi-Fi standard uses Orthogonal frequency-division multiple access (OFDMA) technology to simultaneously transmit data to numerous devices, reducing latency and overheads.
Support Multiple Frequency Bands
Unlike Wi-Fi 5, which only supports a single frequency band, the 802.11ax standard (Wi-Fi 6) uses multiple bands for data transmission. It supports the 2.4 GHz and the 5 GHz bands, ensuring users make the most out of both worlds. Besides, the new Wi-Fi 6E standard supports the recently introduced 6 GHz band. If you want to experience faster speeds, you can switch your device to the 5 GHz band. The 2.4 GHz band is ideal for extended network coverage.

Higher-Order Modulation
While Wi-Fi 5 supports 256-QAM (quadrature amplitude modulation), Wi-Fi 6 upholds 1024-QAM. This feature lets your router combine multiple amplitude modulation signals into a single channel, boosting signal strength, increasing transmission speeds, and reducing interference.
Enhanced MU-MIMO Technology
Another technology that Wi-Fi 6 uses is MU-MIMO, which stands for Multi-User Multiple-Input Multiple-Output. This technology made its debut with Wi-Fi 5. It allows multiple devices to communicate with your wireless router simultaneously.
MU-MIMO Explained
However, MU-MIMO on Wi-Fi 5 is only available downstream and can only support four simultaneous streams. In contrast, MU-MIMO on the 802.11ax standard is available downstream and upstream and can support twelve simultaneous streams.
Supports Beamforming Technology
Legacy Wi-Fi standards usually send transmissions in any direction, leading to lost signals. Wi-Fi experts introduced beamforming technology with the Wi-Fi 5 standard to help curb this problem. Wi-Fi 6 also supports beamforming, a technique that transmits data in a specific direction. It sends data packets directly to the connected devices, improving signal strength and eliminating dead spots.

Better Network Coverage
Since Wi-Fi 6 supports multiple frequency bands, it has better network coverage than its predecessor, Wi-Fi 5. It uses the 2.4 GHz band, renowned for its extended range of about 150 feet indoors and 300 feet outdoors. The 2.4 GHz frequency band can also effortlessly penetrate through solid obstacles, thick walls, and floors without creating dead zones in your space.
Lower Energy Consumption
Wi-Fi 6 routers are energy-efficient and can help reduce the power consumption in your household or commercial premises. With higher transmission rates and more efficient signal allocation, your devices do not have to consume much power. The smooth and seamless data transfer can help conserve energy since you do not have to stay online for prolonged periods.
Backward Compatible
Another benefit of upgrading to the 802.11ax standard is backward compatibility. You do not need to worry whether or not your devices support Wi-Fi 6 since it is backward compatible and can work with older, legacy versions and gadgets. Moreover, Wi-Fi 6 is also future-proof, and many people predict it will remain in use for years, although Wi-Fi 7 is just around the corner.
Basic Service Set Coloring
Wi-Fi 6 is less prone to interference, and it can minimize disruptions from nearby networks using a technology called Basic Service Set Coloring (BSS). For instance, if you and your neighbor have Wi-Fi routers, the signals from the two neighboring networks can overlap and cause interference. BSS technology colors the signals from your network and distinguishes them from your neighbor’s signals, ensuring it goes to the intended recipient.

Wi-Fi 6 has the most advanced security features in Wi-Fi Protected Access 3 (WPA3). This security standard for wireless networks provides cutting-edge features that enable a more robust authentication process, preventing hacking attempts. For one to certify your router has Wi-Fi 6, it must have WPA3.
Cons of Wi-Fi 6
The excitement surrounding Wi-Fi 6 can make someone assume this Wi-Fi standard has no faults. However, Wi-Fi is not immune to shortcomings. Here are a few drawbacks to consider:
Narrower Sub-Carrier Spacing
Wi-Fi 6 uses Orthogonal frequency-division multiple access (OFDMA) to transmit data simultaneously to multiple devices. It subdivides channels into smaller subcarriers called resource units.
While these carriers deliver data to multiple devices more efficiently, their spacing is narrow at 78KHz, making them prone to Wi-Fi noise. For this reason, you might require phase noise oscillators to deal with this issue.
Requires Gigabit Broadband Connection
If you do not have a Gigabit broadband connection plan, do not waste time investing in a Wi-Fi 6 router. After all, Wi-Fi 6 is the fastest Wi-Fi standard, with maximum transmission rates exceeding 10 Gbps. A fast broadband connection plan will ensure you fully exploit Wi-Fi 6 technology for a fantastic internet experience.
Not Readily Available
Even though Wi-Fi 6 has been around for more than two years, Wi-Fi 6 routers are not readily available. Many shops and online stores are stuck with Wi-Fi 4 and Wi-Fi 5 routers, perhaps because most customers prefer these two Wi-Fi standards. Besides, many people consider Wi-Fi 6 a preserve for commercial use.
Pricey
If there’s a router that will force you to dig deeper into your pockets, it has to be a Wi-Fi 6 router. They do not come cheaply, with most costing hundreds of dollars, making them out of reach for many casual Wi-Fi users. However, if you can afford it, go for it since Wi-Fi 6 routers are worth every dime.
Conclusion
If you want to connect multiple devices to the internet without overwhelming your wireless network, consider installing a Wi-Fi 6 router. The primary objective of Wi-Fi 6 is not to increase transmission speeds but improve connections and performances in dense wireless environments.
It doesn’t matter how many gadgets you want to connect. Whether you have a laptop, smartphone, tablet, thermostat, refrigerator, or security camera, Wi-Fi 6 can support these devices without compromising performance or slowing down your network.
