The "bright" future of wireless technology

The widespread development of telecom is an obvious trend of the beginning of the 21st century.

There are 1.4 million base stations in the world and more than 5 billion mobile phones, wireless communications penetrate all aspects of life, and this process will only intensify in the foreseeable future.

But already now - there are visible on the horizon the fundamental boundaries of the existing level of technology:

• Exhaustibility - frequency resources are limited;
• Efficiency - most of the energy is spent on cooling equipment;
• Accessibility - the ability to cover the entire territory of the planet with mobile communication is a big question;
• The security of data transmission is a very serious problem, the relevance of which will increase with every turn of technical progress and the increase in the amount of financial (and not only) resources flowing over wireless networks.

From the stage of the TED lecture hall, Harald Haas presented his scenario for the development of wireless data transmission technologies, recalling that light is the same part of the electromagnetic spectrum as radio waves (the width of the light spectrum is 10,000 times wider than the radio wave spectrum).

Harald Haas promises to extract 10 Mbit / s from the usual three-dollar lamp. And given that today our planet is covered by 14 billion lamps - the infrastructure is almost ready.

And although the usual curtain will be a serious obstacle to such a connection, such "scientific tricks" can not fail to fascinate.
