5 Antenna Information
5.1 Antenna Type
TCLWRQS1 uses the onboard PCB antenna.
5.2 Antenna Interference Reduction
To ensure optimal Wi-Fi performance when the Wi-Fi module uses an onboard PCB antenna,
it is recommended that the antenna be at least 15 mm away from other metal parts.
To prevent adverse impact on the antenna performance, do not use copper or route cables
along the antenna area on the PCB.
For details about the onboard PCB antenna area on a module, see Figure 3.
