Wi-Fi Recommendations for Raspberry Shake#
Contents
Overview#
Wi-Fi can be used with Raspberry Shake, but we do not recommend it as the primary connection method. Whenever possible, use wired Ethernet for a stable and interference-free connection.
The reason is that Wi-Fi signals, particularly those coming from the internal Raspberry Pi antenna, generate electromagnetic noise that interferes with the Shake’s seismic readings. This is particularly true for low-frequency signals and can cause false or distorted events.
Acceptable Use Cases#
Wi-Fi may be used safely in some cases:
When using a USB Wi-Fi dongle, not the internal Raspberry Pi Wi-Fi.
When the dongle’s antenna is kept far from the Shake (at least 30–50 cm if possible).
When using a shielded USB extension cable to reduce interference.
When physical Ethernet wiring is not practical (for example, in educational or portable setups).
We recommend testing your noise levels before and after enabling Wi-Fi to ensure signal quality is not compromised for the purposes of your work.
Alternatives to Wi-Fi#
If Ethernet (LAN) cabling is the main challenge, consider one of the following options:
High-quality low-noise Ethernet-over-powerline adapters, which use your home’s electrical wiring to carry Ethernet signals.
Ethernet extension cables paired with repeaters, which can run long distances with minimal signal loss.
Wi-Fi bridges or extenders placed several meters away from the Shake, running an Ethernet cable from those to the Shake.
Advanced Information#
If Wi-Fi is your only option, and want to configure it manually or through the Shake’s web interface, refer to Configuring Wi-Fi and USB Dongles.
