The physical dimensions are shown in table 9. Units are in mm.
Figure 4. Physical Dimensions of Module
For ideal RF-Performance when using the on-board antenna, the antenna should be located at the
edge of the carrier PCB. There should be no components, tracks or copper planes in the keep out
area which should be as large as possible, preferably 10-15mm around the antenna.
If using the U.FL RF-Connector the keep out area can be significantly reduced. The Module
transmit/receive range will depend strongly on the antenna used and also the housing of the
finished product.
