+=====Qi standard introduction=====
 ====What is Qi====
-The Qi (pronounced chee) standard is a widely adopted wireless power transfer (WPT) technology designed for mobile devices. First introduced in **July 2010** with Version 1.0, Qi has since become the **leading global standard** for wireless charging. Developed by the **Wireless Power Consortium (WPC)** and supported by 285 companies, in particular major technology companies such as **Apple, Samsung, Google and Meta**, ensuring its continuous evolution and global adoption. Today, there are more than **11,000 Qi Certified products** on the market.
+The Qi (pronounced chee) standard is a inductive power transfer (IPT) technology. The standard is developed for smartphones and other mobile devices. Transmitter and receiver are placed in **close proximity** to each other (cm). This close coupling is essential for maximizing efficiency. To further enhance efficiency, the Qi standard incorporates **technology-specific features**. These features are discussed in detail later in this article. Today, there are more than **11,000 Qi Certified products** on the market.
+====Who are the developers====
+The Qi standard was developed by the **Wireless Power Consortium (WPC)** and was first introduced in July 2010 with Version 1.0. WPC is an open standards development group that collaborates with electronics and technology companies. Today, the consortium consists of over 300 member companies worldwide, including major technology firms such as **Apple, Samsung, Google, and Meta**
+====Previous versions====
 The Qi standard has been updated several times over the years to improve performance, compatibility, and efficiency:

 ====Key advantages====
-All these previous improvements have significantly improved the performance and capabilities of Qi, resulting in several key advantages:
+All previous improvements of the Qi standard resulted in several key advantages. The updated list of these **technology-specific features** are:
   * [[Qi power transfer|Transmitter can deliver up to 15W]]
   * Operating frequency of 360kHz

 ====Other WPT technologies====
-Other WPT technologies include the AirFuel Alliance standard (formerly Power Matters Allicance) and its magnetic resonance-based approach. While these alternatives offer benefits such as longer-range charging, the Qi standard remains the most widely adopted due to its efficiency, compatibility and strong industry support.
