Wi-Fi Recommendations for Raspberry Shake#

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.
