1. Client Reaction Between Two APs
If clients are between two APs with similar signal strength, they typically evaluate which AP provides the better connection. The decision often hinges on factors such as signal strength (measured in dBm), signal quality, and load on the APs. Clients do not use a fixed dBm threshold universally; instead, they use their algorithms to decide when to switch to a better AP.
2. Switching Process Between APs
The process of switching between APs (roaming) is generally client-driven. The client (e.g., an iPhone) continuously monitors the signal strength of the connected AP and neighboring APs. When the client determines that another AP offers a significantly better connection, it will disconnect from the current AP and connect to the better one. The AP itself doesn’t typically instruct the client to move unless it has a min dB set which will force a disconnect.
3. Frequency of Polling and Decision-Making
Clients frequently check the signal quality of their current connection and neighbouring APs. This polling can happen every few seconds to minutes, depending on the client’s operating system and the network configuration. The exact frequency can vary but is designed to ensure optimal connectivity without causing excessive battery drain.
4. Band Preference (2.4 GHz vs. 5 GHz)
When a client detects a stronger 2.4 GHz signal from AP1 and a stronger 5 GHz signal from AP2, the decision can depend on several factors:
- Client Algorithms: Many modern devices prefer the 5 GHz band due to higher throughput and less interference.
- Band Steering: Some APs, including the Alta Labs AP6 Pro, can guide clients to the 5 GHz band if it’s deemed more optimal.
5. AP Placement and Signal Penetration
Mounting an AP on a wall can result in lower signal strength behind the wall. Placing the AP about 40 cm (1.3 feet) away from the wall on a shelf may improve signal penetration behind the AP slightly, but it also increases signal reflection off the wall and can improve coverage in front of the AP. This placement can indeed create a better overall signal distribution by leveraging reflections.
6. AP-6 Pro vs. Regular AP-6 for Home Deployment
For a home deployment with ~50 WiFi clients and a 1 Gbit Up/Down Internet connection, the regular AP-6 might have sufficed. The AP-6 Pro offers higher performance, more advanced features, and future-proofing, which can be beneficial as your needs grow. Given your aim for future-proofing and optimal performance, the AP-6 Pro is a solid choice. It ensures you can handle increased demands and new technologies as they emerge.
