Engineering 5G

How do we make sure that Canadians will have excellent 5G wireless coverage everywhere? The higher frequency spectrum needed for 5G doesn't pass through doors or even trees like todays mobile signals do. So what can we do about it? Canada's Communications Research Centre has found a cool solution. Check out this short animated video to find out what it is.

Mobile networks today give you blazing speeds anytime, anywhere.

Road appears with wireless devices, like radios, TVs, tablet and laptops, travelling along it

Well, almost anywhere...

(sound of crickets)
But in the near future, as billions of new devices become connected, we'll need to open new, higher frequency spectrum to keep up.

New red sine wave is added higher up than the others

Unfortunately, these frequencies can't easily go through walls, doors, or trees like the ones we use today...
How do we stay on top of this?

Scene changes to a road with houses and red sine waves, representing 5G spectrum, are hitting houses and trees

One solution would be to install transmitters everywhere...

Many transmitters appear along the road with houses

... but we've come up with something a lot cooler to improve 5G coverage!
Something our scientists at the Communications Research Centre are calling "engineered surfaces". So what are they?... and what do they do?

Text: 5G Coverage with Engineered Surfaces

Well, think of the window of a microwave oven: it keeps the microwaves in to heat your food, and lets light waves out so you can see inside.

Similarly, 5G engineered surfaces use printed patterns to redirect wireless signals
in any direction to reach even the most remote corners.

These low-cost printed electronics can be integrated into wallpaper, curtains…

…making sure all Canadians can get 5G connected anytime, anywhere.
