Wireless power transmission (WPT) is a technology that allows electrical energy to be sent from one point to another without using physical cables.
As time progresses, wireless power transmission technology has been widely used in various fields, from wireless cellphone charging to applications in the industrial and health sectors.
But do you know what wireless power transmission is from history and how it works?

What is Wireless Power Transmission
Wireless power transmission (WPT) is the process of transferring electrical energy from a power source to a receiving device without cables. Unlike traditional charging systems that rely on cables, WPT uses methods such as electromagnetic induction and magnetic resonance to transmit energy.
This system enables wireless charging of devices, bringing convenience to users and opening up new application opportunities.
The History of Wireless Power Transmission
Maxwell’s hypothesis of electromagnetism, distributed in 1865, notices electromagnetic waves moving at the speed of light and concluded that light itself was fair such a wave.
In 1886 Hertz performed a fruitful exploration with beat remote vitality exchange. He created a device that created and identified microwaves in the UHF region.
Tesla moreover performed tests in the field of beat remote vitality exchange in 1899. His Amplifying Transmitter, an early sort of Tesla Coil that measured 16 meters in distance across, may transmit tens of thousands of watts without wires.
Tesla evidently overseen to light 200 lights, without wires, from 40 kilometers absent, in spite of the fact that no documentation from Tesla’s claim records was ever distributed.
In 1897 he recorded his beginning with licenses for the Wardenclyffe Tower, which was implied to be a pilot plant for his “World Remote System” to broadcast vitality around the globe. The office was never completely operational and was not completed due to financial problems.
How Wireless Power Transmission Works
Wireless power transmission technology works based on several principles, namely:
1. Inductive coupling (electromagnetic induction)
This technique transfers power through an electromagnetic field between two coils that are close together. The coil in the power source generates a magnetic field, which then transfers energy to the coil in the receiving device.
This technology is commonly used in wireless chargers for cell phones and other small devices.
2. Resonant inductive coupling
This method is similar to induction but uses matched resonant frequencies between the transmitter and receiver to increase the efficiency of power transfer over longer distances. Resonant coupling is widely applied in the wireless charging of electric vehicles.
3. Microwave power transmission
Using microwaves to send energy over longer distances. This technology is more common in projects that require long-distance power transmission, but its efficiency decreases as distance increases.
4. Laser-based power transmission
This method uses a laser beam directed at a receiver which can convert light energy into electrical energy. This application is used in very specific situations, especially for devices that require small amounts of power.
The Future of Wireless Power Transmission
With the growing need for smart devices and electric vehicles, wireless power transmission technology has great prospects in the future.
Innovations in transmission range, energy efficiency, and security could expand the use of WPT across industries.
Current research is focused on improving efficiency, extending range, and reducing environmental impact, so WPT could become a mainstream charging solution in the future.
Wireless Power Transmission Regulations in Indonesia
Every wireless power transmission (WPT) circulated or sold in Indonesia must be certified by the Directorate General of Digital Infrastructure (DJID).
This certification guarantees that the gadget meets the security and quality guidelines set by the government and does not meddle with other communication gadgets in the region.
The certification handle is managed by the pertinent specialists and incorporates specialized testing, such as recurrence alteration, security of utilization, as well as gadget compatibility in the encompassing environment.
After all tests are completed, gadgets that pass will be recorded in a Test Result Report as the premise for qualification to get a conveyance permit in Indonesia.
The Test Result Report ensures that the gadget meets specialized details and is secure for utilization by shoppers while expanding certainty in the item in the market.
For companies wishing to advertise WPT in Indonesia, Type Approval Certification Services for ICT Products are accessible to help with this preparation.
This benefit covers the planning of specialized and regulatory archives, testing of WPT concurring with pertinent measures, and authoritative completion to guarantee the gadget is prepared for the showcase.
By utilizing this benefit, companies can guarantee that the whole preparation is more effective, whereas certified items give a sense of security and comfort to customers.
