WattUp, RF wireless power transfer, allows you charge and power your electronics up to 5 meters. With WattUp the future of the digital world will drive to new uncountable possibilities in electronics and computer science technologies. Recently, the highly integrated power management, AC / DC power conversion, charging and Bluetooth low-power technology provider Dialog Semiconductor and Energous jointly launched the next generation of RF wireless charging solution WattUp.
DA4100 Wireless Power Transmitter
The technology includes DA4100 power transmitter and DA2200, DA2210 wireless charging receiver. It works with a small, low-cost antenna to replace the current larger coil and has the ability transfer RF energy up to 5 meters which we can use for charging our gadgets.
PCB Antenna
So you can throw away the regular charger and its cable! With WattUp, up to 5 meters wireless charging RF technology becomes real. WattUp is a radio frequency (RF) -based charging solution that replaces the induction coil with a PCB antenna. That provides a scalable power over the radio band and doubles the effective charging up to a distance of 4.5 meters. The future technology will need to install RF power transmitter in each room of the house.

So, shortly, you can wear the smart watch, or hold the smartphone in your pocket with their battery charging anytime without the hurdles of chargers and cables.
RF VS Induction Wireless Charging
Currently, mostly wireless charging solutions in the market have a base on electromagnetic induction or magnetic resonance technology. In which, the receiver and the transmitter in between distance creates a wireless link. That is not enough to say it wireless. More accurately we should say it docking charging system.

Also, with the conventional wireless charging system, there is an absolute limit of power transfer. In this method, a lot of electricity gets wasted in induction. In contrast, RF wireless charging method is more flexible and convenient to use.
Get Rid of cables and Batteries in your Gadgets
So, with this new RF power transmitter WattUp, you can have your gadgets on your working table without any wires. As data is already on RF, now you have power also on radio frequency, that will get rid of batteries in your wireless keyboard and wireless mouse set. Along with the gadgets, you hold like watches, tablets, etc. will also get charge by this new gadget WattUp.
Now, we will discuss the main characteristics of RF Wireless Charging Technology WattUp
1) Up to 4 to 5 meters of distance, it will work smoothly.
2) It comes with the PCB antenna instead of an induction coil. So, that reduces the cost.
3) PCB antenna receiver has a tiny size, which you can easily integrate into smaller devices, such as Bluetooth headset.
4) Thre is an option to charge multiple devices at the same time. That means it can feed as per user requirement.
No Radiations in WattUp
As in traditional wireless charging system uses magnetic induction. That extensively creates magnetic field radiations. These radiations are very dangerous to health. However, there is no such problem of emissions in RF Transmitter WattUp. Until now there is no case reported on is radiation hazards. The current WiFi signal frequency lies on 2.4GHz and 5.0GHz bands. And the RF wireless charging frequency band is 5.8GHz. So, there is no interference of communications systems by using WattUp.
Does RF wireless charging will have a high cost?
Wireless charging includes power management module, the transmitter circuit, charging board, etc. But it will also include the patent costs. And the cost of WattUp will be much higher than the traditional chargers.

However, compared to the coil-type wireless chargers, RF wireless charging technology uses low-cost PCB antenna instead of the expensive induction coil. So that will reduce the production cost as well. RF wireless charging system (near field communications), is a one-to-many wireless charging for wearable equipment.
iPhone 8 will have WattUp support?
There is also news over the internet that the up gradation of iPhone 8 will also get WattUp support. That is the next brand from Apple will have wireless charging up to 5 meters with this RF Wireless Powering Technology WattUp.
