These wireless innovations create tangible advantages for phones, laptops, and smart home hubs. With Wi-Fi 7 clients, streaming latency drops below 2 milliseconds under load, and throughput remains stable even in high-interference areas. VR headsets retain high framerates, cloud gaming platforms deliver consistent responsiveness, and 8K video playback streams smoothly without buffering.

Backward compatibility with Wi-Fi 6/6E and Wi-Fi 5 ensures that legacy devices don’t get sidelined. However, when connected to Wi-Fi 7-compatible devices—like the 2024 MacBook Pro or Samsung Galaxy S24 Ultra—the jump in real-world performance becomes unmistakable.

Range and Coverage: Signal Strength Without Compromise

Testing the Limits in Real-World Environments

Distance means little if the signal falls apart halfway through. To test the real-world range of the ASUS RT-BE88U, this router was deployed in a variety of spaces — a 2,500 square foot single-story home, a 3-floor townhouse with concrete walls, and a 4-room office floor packed with interference from neighboring networks.

In the residential setups, the RT-BE88U delivered usable 6 GHz bandwidth up to 55 feet through one drywall and a glass door. In open space, 2.4 GHz coverage extended to 110 feet before signal degradation dropped throughput below 30 Mbps. Within the urban office environment, signal consistency remained impressively stable across the entire 4-room layout, with speeds holding above 500 Mbps on the 5 GHz band even across two concrete walls.

Techniques to Push the Signal Further

ASUS equipped the RT-BE88U with eight external, high-performance antennas configured to optimize beamforming and multi-directional coverage. Apart from hardware, the router leverages ASUS RangeBoost Plus, an AI-based algorithm that dynamically adjusts signal strength and targeting based on active device locations.
