Can 5Ghz Go Through Walls. Today's wifi gear operates at either 2.4ghz or 5ghz. There's also a door around the corner that will occasionally be left.
5 ghz signals are much weaker than 2.4 ghz signals, so they do not pass through walls, ceilings or other obstructions nearly as well as the stronger 2.4 ghz signals.
The more common 2.4 ghz used by most routers and iot devices, and the 5 ghz one offered as an alternative by newer routers. It offered basically the same features as 802.11a, but used less expensive the frequency of the signal (in this case 2.4ghz versus 5ghz) comes into play, as does the composition of the walls. Today's wifi gear operates at either 2.4ghz or 5ghz. This happens because of electromagnetic waves' peculiar characteristics:
