Radio signal interference
How can I avoid radio signal interference from wireless devices?
1.
Ensure camera installation complies with
Electromagnetic Compatibility
.
Wireless devices and USB 3.0 / 3.1 Gen 1 commonly use 2.4 GHz frequency (WLAN
uses 2.4, 3.6, and 4.9 GHz).
Even USB 3.0 / 3.1 Gen 1 cables can interfere harmfully with other electromagnetic
devices. For example, despite shielding, a USB 3.0 / 3.1 Gen 1 cable can interfere
with a wireless mouse. Tests have shown an increase of the noise floor up to 20 dB
for the affected devices.
•
To enable maximum bandwidth, 2.4 GHz radio frequencies must be avoided;
therefore, use
maximum shielded cables only
.
•
Keep
maximum distance
between your Alvium USB camera setup and
interfering devices.
•
Use
high-gain antennas
to reduce power of the radio signals.
