VRM Portal
An outdoor antenna typically increases received signal by 15 dB to 25 dB.
Note that when the GX Device is already connected to Ethernet or WiFi, these have priority over the
cellular connection. Even when the available Ethernet or WiFi connection does not have a good
connection to the internet. There is no automatic detection in place which in such case switches over
to the GX GSM. In more technical language: when the cellular data connection is active, it is
configured with a high routing metric. This way, the Linux kernel prioritises Ethernet or Wifi when
these are available.
This screenshot shows how all details look when everything is OK:
7. Supported Frequencies (2G/3G)
2G (GSM/GPRS/EDGE): 850/900/1800/1900 MHz (Quad-Band)
3G (UMTS/HSPA+): 900/2100 MHz (Dual-Band)
Regional Coverage Information
Northern America: 1900 MHz is the most common frequency for 3G, which is unsupported for the
current version of GX GSM.
Australia: The 900MHz 3G frequency in remote areas is typically provided by Optus. Telstra's rural 3G
network operates at 850MHz which is not supported with the current version of GX GSM. Both Telstra
and Optus operate 2100Mhz networks in urban areas, and are supported.
In case of uncertainty please double-check:
