Test and Measurement: NFC Forum releases test specs for wireless charging



NFC Forum has released new test specifications that the group said are the first that will enable manufacturers to certify that their products comply with the NFC Wireless Charging (WLC) 2.0 standard. That standard allows a smartphone, notebook or a dedicated charging device to wirelessly charge other small devices, such as styluses, wireless earbuds, fitness trackers or smart watches and so on, at a power transfer rate of up to one watt.

NFC Forum said that the Universal Stylus Initiative, or USI, is the first organization to test with TR13 and achieve NFC Forum certification — so that as long as the related device has power, the active stylus won’t run out of power, either.

Rohde & Schwarz is hosting a virtual event on May 24 focused on satellite technology development and its intersection with 5G in Non-Terrestrial Networks specifications (more on 5G and NTN here and here). “From the beginning of 3GPP, the vision of ubiquitous communications included the usage of satellite or airborne based network components. In the short history we saw a tremendous development in the satellite and aerospace community as well as in worldwide wireless communication requirements. With 3GPP Release 17, the vision of ubiquitous communication networks including satellite and airborne can become a reality. The global radio access technology 5G New Radio enables NTN connectivity. Diving into some technical challenges of NTN, the event will give insights on how to leverage the deployment of NTN capable devices and networks, ”said Reiner Stuhlfauth, wireless technology manager at Rohde & Schwarz.
