Antenna
You gateway can have different antennas connected. The software has to know about which antenna is configured to adapt the output power adequately.
By default, antenna type is not configured at all.
If the antenna type is not configured, most of the packet forwarders will not run.
Setting a bad antenna type will not damage the gateway.
Available antenna types
Antennas vary in two parameters : ingress protection and gain.
Ingress protection
Indoor and outdoor antennas are available. Whether it's one or the other, this has no impact on the software and is therefore not to be configured.
Gain
The gain depends on the antenna model you have. There are 4 different antennas depending on the type and the generation.
Type | Length | Gain | Illustration |
---|---|---|---|
Indoor | Small 210mm (8,27 inches) | 2dBi | |
Outdoor | Small 280mm (11,02 inches) | 3dBi (labelled) | |
Outdoor | Large 500mm (19,69 inches) | Check label (4dBi or 5 dBi) If no label: 4dBi |
On the outdoors antenna, the label is graved onto the metal connector base.
The gain has to be configured in the Manager.
Check the antenna gain
