In India, like most other countries, radio frequency is considered a natural resource. In order to effectively control the use of radio frequency spectrum in wireless communication, the Indian government department has set up a special control agency "Wireless Planning and Coordination Department". Its full English name is "Wireless Planning and Coordination Wing", referred to as WPC. Wireless products entering India need to obtain WPC certification.

Specifically, any wireless transmission less than 3000 Ghz that does not use human control is considered "wireless communication" as defined by the WPC. These frequency bands are under the control of WPC. That is, wireless transmissions (such as infrared) with frequencies above 3000 Ghz are not considered "wireless communications". WPC certification does not control these frequency bands.

With the exponential growth in the demand and use of low-power wireless communication devices for everyday use, WPC is constantly updating its rules and regulations to meet the needs of international wireless product market access.

Since India has two types of free and unopened frequency bands, for wireless communication products whose frequency bands and output power fall within the control range, it is necessary to apply for an ETA certificate from WPC. In addition, the holders of ETAs must be locally registered companies. In addition, WPC accepts RF report from CE report to WPC certification, no need to provide samples and tests.
