But in case of brick or concrete 2 4ghz band is preferred because lower frequencies can penetrate much better through thick walls.
Wifi signal through concrete walls.
Wi fi signals don t like concrete or brick walls so avoid these and wireless devices such as microwaves and baby monitors can also interfere with wi fi speeds so bear this in mind when you re.
Concrete will also let the wifi signal pass right through and with it the rf radiation.
However if you are dealing with brick or concrete your primary concern is the ability for your wi fi signal to penetrate the materials in your walls.
It has a strong range and can easily get to where you need it to go through any wall.
Concrete concrete with and without metal reinforcement is one of the worst building materials for wireless signals to pass through but masonry block and bricks can also be serious barriers for wi fi.
This is because we add metal into the equation.
But when we are talking about reinforced concrete the signal and the radiation will be weakened substantially.
Signal loss by the numbers.
Materials such as drywall plywood other kinds of wood and glass can be easily penetrated by wireless signals.
However it does weaken the signal a little bit.
The best wireless router for penetrating concrete walls is the netgear nighthawk r6900p.
Plywood and drywall come close to zero signal loss in tests.

The reinforcing steel rebar in the concrete somewhat depending on its denseness pulls even more juice out of your signal.
This is a versatile router that provides all of the supports that you would really want to get from your home router.
However in reality some walls are thicker or use reinforced concrete and may block some of the signals.
