Therefore, the coverage of the acquisition is determined by the coverage of the mobile phone and router signal (transmitted signal strength). It is recommended to use it within a radius of 30 meters (? × 30 × 30 = 2800, that is, about 2800 square meters of coverage), usually empty to 50-100 meters, the limit distance of 1000 meters Acquisition speed 1. WiFi has 13 channels. Because the signals of mobile phones and routers are distributed in different channels, 13 channels must be traversed and scanned once. Each channel scan takes about 250 milliseconds, that is, it takes about 3 seconds to scan one round. Clock (channel switching time). 2. The experience value is about 80% of the scan can be collected in 1 round, and more than 95% can be collected in the scan 2 rounds. Therefore, it is recommended to stay in one place and wait for scanning 1~2 rounds. Specification: Product detailed size: 44.2x22mm/1.74x0.87inch Package Includes: 1 Piece Serial WiFi probe
