SIMO is a smart antenna technology that uses a single antenna at the transmitter side and two antennas
at the receiver side, which can improve RX performance.
6.7. Electrostatic Discharge
The module is not protected against electrostatics discharge (ESD) in general. Consequently, it is subject
to ESD handling precautions that typically apply to ESD sensitive components. Proper ESD handling and
packaging procedures must be applied throughout the processing, handling and operation of any
application that incorporates the module.
The following table shows the module electrostatics discharge characteristics.
