GPRS
The device with GPRS includes an FME male type connector for an external
antenna. Any kind of external 50 Ω dual-band antenna can be used intended for
GSM900 (880–960 MHz) and GSM1800, also known as PCN, (1710–1880 MHz)
frequency bands. The antenna is connected directly to the connector located on the
device's back panel.
Commercially available antennas are usually provided with a flexible 50 Ω cable
with a length of 2–3 meters and a female type FME connector.
The device's IEC 60870-5-104 gateway is tested with antennas from Hirschmann
Rheinmetall Elektronik GmbH. Examples of tested external antennas include the
sticker type and magnetic mount antennas.
