Basement, first floor and second floor are good. On the t-mobil gateway I added Two (MIMO Antenna (600451))"

Mesh WiFi systems can work effectively with concrete walls, but the performance may vary depending on the thickness and density of the concrete, as well as other factors such as the distance between mesh nodes and the presence of obstructions.

Concrete walls are known to attenuate WiFi signals, meaning they can weaken or block the transmission of wireless signals. This attenuation can result in reduced WiFi coverage and slower speeds, especially if the concrete walls are thick or reinforced with metal.

However, mesh WiFi systems are designed to overcome obstacles like concrete walls by using multiple interconnected nodes to create a seamless network with extended coverage. Each mesh node communicates with neighboring nodes, forming a mesh network that blankets your home or office with WiFi coverage.

When deploying a mesh WiFi system in a location with concrete walls, consider the following tips to optimize performance:

Node Placement: Place mesh nodes strategically throughout your home or office to ensure optimal coverage. Position nodes in areas with line-of-sight to each other and minimize the number of walls or obstacles between nodes to improve signal strength and reliability.
Signal Penetration: Mesh WiFi systems with dedicated backhaul channels or tri-band technology can penetrate concrete walls more effectively than single-band systems. Look for mesh systems that offer strong signal penetration capabilities for better performance in challenging environments.
Mesh Node Density: Depending on the thickness and density of the concrete walls, you may need to deploy additional mesh nodes to ensure adequate coverage and signal strength in every area of your home or office. Experiment with different node placements and configurations to find the optimal setup for your specific environment.
Wired Backhaul: If possible, consider using wired Ethernet connections to connect mesh nodes instead of relying solely on wireless backhaul. Wired backhaul provides faster and more reliable connections between nodes, reducing the impact of signal attenuation caused by concrete walls.
WiFi Channel Optimization: Use WiFi analyzer tools to identify and select the least congested WiFi channels for your mesh network. Avoid channels that overlap with neighboring networks or sources of interference to minimize signal degradation and maximize performance.
By following these tips and choosing a high-quality mesh WiFi system with robust signal penetration capabilities, you can overcome the challenges posed by concrete walls and enjoy reliable, high-speed WiFi coverage throughout your home or office.

Is mesh WiFi good for thick walls?

Yes, mesh WiFi systems can be an excellent solution for providing reliable WiFi coverage in environments with thick walls. Thick walls, such as those made of concrete or brick, can pose challenges for traditional WiFi routers by attenuating wireless signals and creating WiFi dead zones. However, mesh WiFi systems are specifically designed to overcome these obstacles and provide seamless coverage throughout your home or office.

Here's why mesh WiFi systems are well-suited for environments with thick walls:

Expanded Coverage: Mesh WiFi systems use multiple interconnected nodes to create a unified network with extended coverage. Each mesh node communicates with neighboring nodes, effectively blanketing your home or office with WiFi coverage. This allows the WiFi signal to penetrate through thick walls and reach areas that may be inaccessible to a single router.

Flexible Placement: Mesh WiFi nodes can be strategically placed throughout your home to optimize coverage and signal strength. By placing nodes in areas with line-of-sight to each other and minimizing the number of walls or obstacles between nodes, you can ensure better WiFi performance in every room.

Intelligent Routing: Mesh WiFi systems use intelligent routing algorithms to dynamically adjust the network's configuration and optimize data transmission paths. This allows the system to adapt to changes in the environment, such as signal interference or changes in device location, ensuring consistent and reliable WiFi connectivity.

Self-Healing: In the event of a node failure or network disruption, mesh WiFi systems can automatically reroute traffic through alternative paths, minimizing downtime and ensuring uninterrupted connectivity. This self-healing capability is particularly useful in environments with thick walls, where signal attenuation or interference may occur.

Scalability: Mesh WiFi systems are scalable, allowing you to add additional nodes to expand coverage as needed. If you encounter WiFi dead zones or areas with poor signal strength due to thick walls, you can easily extend your mesh network by adding more nodes to improve coverage and performance.

Overall, mesh WiFi systems are an effective solution for overcoming the challenges posed by thick walls and providing reliable WiFi coverage in challenging environments. By leveraging the flexibility, intelligence, and scalability of mesh technology, you can enjoy seamless connectivity throughout your home or office, regardless of wall thickness or other obstacles.

Can Wi-Fi 6 penetrate concrete walls?

While WiFi 6 (802.11ax) offers several improvements over previous WiFi standards, such as increased network capacity, faster speeds, and better performance in crowded environments, it does not inherently improve the ability of WiFi signals to penetrate concrete walls. The ability of WiFi signals to penetrate obstacles like concrete walls primarily depends on factors such as frequency, signal strength, and the thickness and density of the walls.

WiFi 6 operates on the same frequency bands (2.4GHz and 5GHz) as previous WiFi standards, so it faces similar challenges when it comes to penetrating obstacles like concrete walls. However, WiFi 6 routers may offer better overall performance and coverage compared to older routers, thanks to technologies like Orthogonal Frequency Division Multiple Access (OFDMA) and Target Wake Time (TWT), which improve efficiency and reduce latency.

While WiFi 6 may not improve the ability of WiFi signals to penetrate concrete walls, there are several steps you can take to optimize WiFi coverage in environments with obstacles like concrete walls:

Proper Router Placement: Place your WiFi router in a central location and away from obstructions to maximize coverage throughout your home or office. Avoid placing the router near large metal objects or appliances that can interfere with the WiFi signal.

Use Mesh WiFi Systems: Mesh WiFi systems consist of multiple interconnected nodes that work together to provide seamless coverage throughout your home. By strategically placing mesh nodes, you can overcome obstacles like concrete walls and extend WiFi coverage to every corner of your space.

External Antennas: Consider using WiFi routers or access points with external antennas, as they can help improve signal strength and coverage. Position the antennas vertically for optimal signal propagation.

WiFi Extenders or Repeaters: WiFi extenders or repeaters can help extend the range of your WiFi network by amplifying and retransmitting the signal. Place extenders strategically to ensure optimal coverage in areas with weak signals.

Powerline Adapters: Powerline adapters utilize existing electrical wiring to extend the reach of your WiFi network. They can be particularly useful in environments with thick walls where WiFi signals struggle to penetrate.

Overall, while WiFi 6 offers significant performance improvements over previous WiFi standards, it does not inherently improve the ability of WiFi signals to penetrate obstacles like concrete walls. However, by implementing the strategies outlined above, you can optimize WiFi coverage and ensure reliable connectivity throughout your home or office.
