Data Transmission in the Air: Complete Guide

This guide provides a clear overview of data transmission in the air, including the main concepts, practical steps, and common questions. Use it to understand the topic, compare the available options, and make a more informed decision.

The experiment faced many challenges such as air turbulence and thermal phenomena but was successful.

The team used a microelectromechanical system (MEMS) chip with 97 mirrors to transmit and achieve a bandwidth of one terabit per second (equivalent to 1,000 gigabits per second). When using standard technology the system can scale up to 40 terabits/sec. This success opens up the possibility of high-speed, cost-effective Internet connectivity through a constellation of near-Earth satellites.

Laser beams face many factors as they travel through dense air near the ground that affect the motion of light waves and data transmission. The biggest challenges are the crowded megacities, the water surface of Lake Thun, the erratic turbulence of air particles over the snow-covered high mountains and the Aare plane, which cause errors in the transmitted data. In addition, the phenomenon of heat causing the air to flicker also disrupts the uniformity of light motion.

To limit the engineering of the laser system, the mirrors correct the phase shift of the laser beam at 1,500 times/second based on the intersection surface along the slope. This allows the team to transmit more information per unit of time than the radio technology used in satellite Internet connections.

The team's new technology has the potential to have a major impact on the global Internet infrastructure, especially in remote areas. In the experiment, the system could easily scale up to 40 channels and 40 terabit/s transmission rate, so it could be a promising alternative to current deep sea cables.
