Wi-Fi has its days numbered: optical system at 362 Gbps

Imagine a future where the Wi-Fi you know is no longer enough. A team of researchers from the United Kingdom has created a wireless system capable of reaching up to 362.7 Gbps, a speed that seems like science fiction but is already a reality.

This innovation not only promises unprecedented speeds but also reduces energy consumption and the usual interference of current networks. It is clear that the world of connectivity is about to change radically.

How the optical system works

The VCSEL lasers: the heart of the new technology

The system is based on a compact chip that uses an array of small lasers called VCSEL (Vertical Cavity Surface Emitting Laser), technologies already present in data centers but now adapted for domestic and office wireless connections.

During testing, 21 lasers from a 5x5 array were activated simultaneously, each transmitting between 13 and 19 Gbps. This allowed reaching a record aggregate speed of 362.7 Gbps at a connection two meters away.

Energy efficiency and sustainability

One striking fact is the energy consumption: only 1.4 nanojoules per bit, about half of what comparable Wi-Fi technologies consume.

In a context where global network energy consumption is increasing, this feature makes the new optoelectronic technology very attractive for a sustainable future.

Less interference and more stable connections

Precise control of lighting with microlenses

One of the biggest challenges was to prevent the light beams from interfering with each other. For this reason, the researchers designed an optical system that directs each signal to specific areas using microlenses and a grid scheme.

Tests showed lighting uniformity over 90%, which allows maintaining multiple simultaneous connections without quality loss.

Complementing Wi-Fi, not replacing it

It must be clear that this technology does not aim to eliminate current Wi-Fi but to complement it. The idea is to relieve the saturation of conventional networks, especially in spaces with many devices connected at the same time.

This opens the door to a new generation of wireless communications where light will play a fundamental role in daily connectivity.

Benefits and practical applications

Record speeds for the era of streaming and video calls

With the exponential increase of devices and services like video calls and streaming, the demand for faster and more stable connections is unstoppable. This new optical technology offers a surprising solution to this problem.

It could revolutionize everything from the office to the home, improving the quality of users’ digital experience.

Energy savings and reduction of saturation

The low energy consumption and ability to manage multiple connections without interference make this system ideal for environments with high user density such as offices, shopping centers, or public spaces.

Moreover, it helps reduce the pressure on traditional Wi-Fi networks, making them more efficient and sustainable.

The reality is that we are facing a silent revolution in wireless connectivity. This new optical technology could change the way we access the Internet at home and work.

We will have to see how its implementation evolves and when it becomes widespread, but the future promises to be much faster and more efficient.
