Choosing a Base Station Type
We offer two types of base stations: advanced and budget.
Advanced (Wired) Station:
- Supports Ethernet, 2.4GHz and 5GHz WiFi, 4G/5G USB modem
- Data Transmission via Radio Modem
- Powered via USB adapter or PoE
- Based on Raspberry Pi 4B
- Can be rack-mounted (standard 19-inch rack)
Budget Station:
- Connects via 2.4GHz WiFi only
- Powered by USB adapter only
- Based on the compact Raspberry Pi ZERO 2W
- Features an NTRIP LED and USB output from the receiver
Note:
WiFi without an external antenna can be weak. It will work best in the same room as the access point or maybe one wall away. This is especially true for 2.4GHz, which tends to be overcrowded in apartment buildings. So either get a wired station and connect it via Ethernet, or before purchasing a budget station, disable 5GHz on your smartphone and check WiFi quality where the station will be installed. This is explained in a bit more detail in the section “Connection Drops"
Aside from the ability to place a wired station far beyond WiFi range, the budget station offers better functionality overall.
That’s because it also acts as a GNSS receiver. If you don’t need the base station features, you can simply disable the “Main Service” and use it as a high-quality USB GNSS receiver.
