To obtain Wireless Planning & Coordination (WPC) approval for hotspot devices, you will need to ensure that your device complies with the WPC's standards for wireless communication.

Hotspot devices typically operate using cellular networks, and therefore require approval from the Department of Telecommunications (DoT) as well as the WPC in India. You will need to submit an application and required documents to the WPC and the DoT, including a technical description of the device, test reports, and a copy of the user manual.

The WPC has different categories for radio frequency devices, and your hotspot device will likely fall under the "high power device" category. Once your application is approved, you will need to obtain a frequency allocation from the WPC. This ensures that your device operates on an assigned frequency that does not interfere with other wireless devices.

In addition to WPC approval, you will need to obtain type approval from the DoT, which regulates the use of telecommunications equipment in India. This process involves submitting an application to the Wireless Planning and Coordination Wing (WPC), which is a branch of the DoT.

It is important to note that WPC and DoT approval is mandatory for all hotspot devices that operate in India. Failure to obtain these approvals can result in fines or legal penalties. Therefore, it is important to ensure that your device complies with the WPC and DoT regulations and undergoes the necessary testing and approval process before you begin marketing or selling your product in India.
