Abstract
A roaming method based on MESH WIFI executable by an electronic device, comprising: calculating noise values and interference coefficients of a primary access point (AP) and surrounding APs, adjusting power values between the primary AP and the surrounding APs based on the noise values and the interference coefficients according to normalization, and, when a target AP from the surrounding APs reaches a preset condition, switching the client to connect to the target AP.
Claims8
A roaming method based on MESH WIFI executable by a client, comprising:
- by using a multiple access point (multi-AP) agent, monitoring a primary access point (AP) connected by the client in real-time and calculating noise values between the primary AP and surrounding APs according to mutual interference characteristics of the APs using formula (1) represented as:
- Noise
- fromotherAPs

- by using the multi-AP agent, calculating interference coefficients Wt(W1,W2) between the primary AP and the surrounding APs, where W1 indicates a leakage ratio calculated according to a center frequency of the primary AP, W2 indicates an interference source power calculated based on the RCPI values, and W(total)=(the interference source power)×(the leakage ratio);
- by using the multi-AP agent, adjusting power values between the primary AP and the surrounding APs according to normalization;
- by using the multi-AP agent, determining whether at least one target AP calculated using formula (3) is qualified, wherein the formula (3) is represented as:
