Wi-Fi repeaters are the "first aid" tool when home wireless connectivity fails, and with the recent approval of the Wi-Fi 7 standard, the question arises whether it's worth investing in a repeater with this new technology. Let's find out.
Advantages of Wi-Fi 7
Wi-Fi 7 vs Wi-Fi 6/6e: Wi-Fi 7 operates on 2.4 GHz, 5 GHz, and 6 GHz bands, offering significant improvements over Wi-Fi 6/6e, including wider bandwidth and support for the 6 GHz band.
Expanded bandwidth: Wi-Fi 7 doubles the maximum bandwidth to 320 MHz, compared to Wi-Fi 6's 160 MHz, allowing more data to pass through and significantly increasing connection speeds.
4096-QAM encoding: Wi-Fi 7 uses more advanced encoding (4096-QAM) which allows more data to be transmitted in each symbol, improving the efficiency and speed of connections.
Improved coverage and speed: Although higher frequency bands offer less range, Wi-Fi 7 compensates with impressive speeds, even over shorter distances.
Device compatibility: To fully leverage the advantages of Wi-Fi 7, both routers and end devices must be compatible with this new standard.
Disadvantages of buying a Wi-Fi 7 repeater right now
- Cost: Wi-Fi 7 repeaters are considerably more expensive than Wi-Fi 6 models.
- Limited compatibility: Currently, there are few devices compatible with Wi-Fi 7, including routers, mobile phones, and network cards.
- Limited availability: The number of Wi-Fi 7 repeater models on the market is still very limited.
Factors affecting "Theoretical" Wi-Fi speed
- Interference: Wi-Fi signal can be affected by other wireless devices, such as microwaves, cordless phones, and Bluetooth devices.
- Distance: Wi-Fi signal weakens with distance. The further a device is from the router, the lower the speed will be.
- Obstacles: Physical objects, such as walls, furniture, and appliances, can block the Wi-Fi signal.
- Interference from other routers: If there are many Wi-Fi routers in the area, there may be congestion in the frequency band.
- Router capacity: Older routers may not be able to reach maximum Wi-Fi speeds.
- Device capacity: Older devices may not be compatible with the latest Wi-Fi standards.
When to buy a Wi-Fi 7 repeater?
Buy a Wi-Fi 7 repeater if:
- You have a Wi-Fi 7 router and several compatible devices.
- The maximum contracted speed is not essential for you.
- You don't need low latency for gaming.
- You need high-speed and stable Wi-Fi coverage.
- You are willing to invest in future technology.
Alternatives to Wi-Fi 7 repeaters
In general, a wired connection is still better than a Wi-Fi 6 or 7 connection, even with the improvements they offer.
- Mesh Systems: Offer more uniform and scalable Wi-Fi coverage, but are more expensive.
- PLC Devices: Use electrical wiring to carry the internet signal, ideal for areas with thick walls.
-
Plastic Optical Fiber (POF): An economical and flexible alternative that offers good performance for most homes.
Plastic optical fiber: A still viable alternative
Plastic optical fiber (POF) is a type of fiber optic cable that uses plastic instead of glass. It is more flexible and economical than traditional optical fiber, making it an attractive option for the home.
Conclusion
Wi-Fi 7 repeaters offer advantages in speed, stability, and capacity. However, their high cost, limited compatibility, and current availability mean they are not the best option for everyone. It is important to analyze your needs and consider alternatives such as Mesh systems, PLC devices, or plastic optical fiber.
