At the height of his career, the pioneering electrical engineer Nikola Tesla became obsessed with an idea.
Thingsdidnt go to plan, and Teslas ambitions for a wireless global electricity supply were never realized.
The last of these, mmWave, opens up much more bandwidth at the cost of shorter transmission distances.
For context, most WiFi routers operate in the 2GHz band.
This is why 5G masts aremore densely clusteredthan 4G masts.
These happen to be the same raw ingredients needed to create a wireless power grid.
Experimenting with 5G power
Theexperimentsused new types of antenna to facilitate wireless charging.
Being able to beam power directly to these IoT devices will encourage the move tofar more efficientmanufacturing practices.
Teething problems
But there will be challenges to overcome before then.
That said, this technology is in its infancy.
