5Antenna
5.1 Antenna type
This product uses IPEX interface connect to stick antenna.
5.2 Antenna interference reduction
To ensure optimal RF performance, it is recommended that the antenna be at least
15 mm away from other metal parts. If metal materials are wrapped around the
antenna, the wireless signals will be reduced greatly, deteriorating the RF
performance.
