Wireless

Wireless network to charge mobile phones and electronic vehicles are at the forefront of the no-connection future.

More than a hundred years have passed since wireless network technology was first established. Much has been changed since then. Wireless technology has been through many twists and turns in evolution. With the introduction of disruptive technologies like the Internet of Things, 5G and artificial intelligence, wireless networks got streamlined further. Wireless network used to charge mobile phones and electronic vehicles are at the forefront of future developments.

Nikola Tesla came up with the idea of transmission of wireless energy in 1880. He put in a lot of efforts to make his initiative ‘Tesla Col’ come true. Unfortunately, even though the concept came out to be very successful, the technology never went mainstream and ultimately fell into novelty and obscurity. In 1901, a brief letter between Britain and Canada became the first wireless transatlantic message to be sent across distant places. The introduction of a portable radio and the discovery of FM frequencies paved the way to think futuristic about wireless technology. After almost five decades, in 1970, the FM frequency framework supported the development of Ethernet and transmissions via high-speed packets. The famed phone Motorola came onto the scene with 1G network in 1983. Ever since the beginning of the 21st century, emerging concepts of 4G, 5G and LTE networks have proved the improvement of wireless technology.

Today, there are nearly half-dozen wireless charging technologies in use, all aimed at disconnecting the device from cables and making it work individually. Most wireless power and charging platforms utilise time-varying electric, magnetic, or electromagnetic fields to transmit power, and can be broken down into two categories namely non-radiative and radiative or near and far-field. Remarkably, since the emergence of IoT, wireless charging is making inroads in the healthcareautomotive and manufacturing industries by increasing the mobility and advances that could allow tiny devices to get power many feet away from the charger. Besides, wireless technologies and devices are also used to monitor and control heating systems that are starting to find applications in domestic, commercial and industrial environments.

Wireless mobile charging technology

Even though wireless technology has been around for a long time, the concept of wireless mobile charging came to impact only a couple of years ago. However, not all countries are quick in adopting a disruptive trend. But more and more mobile manufacturers and electronic device makers are entering the wireless charging market to make a difference. For example, Samsung has supported wireless charging since the Galaxy S6 and Huawei introduced the technology with its Mate 20 Pro model. Wireless mobile chargers transfer power from a power outlet to the device without the need for a connecting cable. It involves a power transmitting pad and a receiver, sometimes in the form of a case attached to a mobile device or built into the phone itself.

Wireless electric vehicle charging system

Whether we agree or not, the increasing fuel price and carbon emission from the fuel vehicles have pushed humankind to embrace innovative and less harmful concepts like electric vehicles. But for electric vehicles, travelling range and charging process are the two major issues affecting its adoption over conventional vehicles. Fortunately, with the introduction of wireless charging technology, electronic vehicle owners are relieved from the stress of waiting in long lines. They can charge their vehicle by just parking it on the parking spot or by parking it by their garage. Some advanced methods show that electric vehicles can even be charged through a wireless medium when they are on the move.
