6.3 GSM Antenna - installation Guidelines

Install the antenna in a place covered by the GSM signal.

The Antenna must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter;

Antenna shall not be installed inside metal cases

Antenna shall be installed also according Antenna manufacturer instructions.

6.4 Electro Magnetic Interference - Guidelines

The GE863-PRO3has been particularly designed in order to keep to a minimum the Electro Magnetic Interferences between the ARM part and the GSM/GPRS engine, however especially the ARM part remains a noisy device that must be threaten with care in order to avoid that its EMI affect the GPRS part through an external coupling.

Therefore:

Keep fast ARM lines far away from Antenna line in order to avoid direct coupling;

Keep fast ARM lines buried in the inner layers, with Ground Layers [fenced with vias] on the top/bottom layers;

If your lines are long, place a series resistor [ in the range of 47Ω – 100 Ω ] close to the GE863- PRO3 ARM ball to reduce the ringing and the EM emissions of the signal

If your PCB lines are very long, place a terminator resistor close to the device line end.
