Use of the infrared units will be affected in outdoor or infrared-intensive environment. Measured in an interference-free and unobstructed environment with a distance of approximately one meter between the mobile device, the router, and the S1. The iOS device used was an iPhone X. The results of testing with different Android device may be different. Outdoor use of the 5.1 GHz and 5.8 GHz frequency bands is prohibited in some areas. Always follow all local laws and regulations in your country or region. Measured in an interference-free and unobstructed environment. For Connection via Wi-Fi, the mobile device used for testing was a sixth-generation iPad (released in 2018). For Connection via Router, several router models were used for testing. FCC: TP-Link Archer C9; SRRC: TP-Link WDR8600; CE: TP-Link Archer C7; MIC: WSR-1160DHP3. The gel beads will swell to a usable size after being soaked in water for four hours.
