In India, like most other countries, RF spectrum is considered to be a natural resource. The use of the RF spectrum for “Wireless Communication” is controlled by the Wireless Planning and Coordination Wing (WPC) , a body specially created by the Government for this purpose.
To be very specific, any wireless transmission less than 3000 GHz and without the use of artificial guide is considered as “Wireless Communication” and is controlled by the WPC. That is to say that wireless transmission at a frequency higher than 3000 GHz (example Infra- Red communications) is not considered to be “Wireless Communication” as defined by WPC and hence is not controlled by the WPC.
From regulatory point of view, WPC issues licenses for importing (WPC Import License) , selling (WPC - Dealer License) , and using (WPC- End-User License) wireless devices that perform Wireless Communications as defined above. An End-User License may be seen as an exclusive ownership of a particular frequency band for a specified period (usually 2 years) bestowed on the licensee by the WPC for which the WPC charges a license fee.
(fee depends on band and application)
With the exponential increase in demand and usage of lower power wireless communications devices for everyday use , WPC , from time to time has amended its rules and regulations to match the international market trends in respect of wireless products.
Accordingly WPC has “de-licensed” several frequency bands of the RF spectrum subject to specified emission power limits, that is to say WPC has “released control” on imports, sale and usage of those products that fall into the so-called “de-licensed” category. A separate cell in the WPC issues “Equipment Type Approval” (ETA) for de-licensed products based on the products RF characteristics as evident from accredited test reports from its manufacturer. A product whose frequency band is contained in the de-licensed spectrum, but whose output power exceeds the specified limit is treated as a licensed category wireless product.
To summarise, a wireless product can be classified either as de-licensed, or as licensed product. A list of de-licensed bands as on 1st January 2011 is as below.

For Licensed products, the process WPC End-User License

On a license, the licensee name, site address, its geo-coordinates, frequency band and max. allowed power is mentioned, Product name , model and manufacturer is not mentioned.
The application involves considerable involvement from the end-user (not from the manufacturer).
1. Application for frequency clearance is file at WPC. The application contains the full details of the proposed installation site, names of employees who will operate the system, geo-coordinates of the location and desired frequency band and power. (There is no mention of product ,model or manufacturer on this application)
2. WPC will analyze the application and check if the frequency is already allotted to some other organisation, or, if the location is close by to airport, military base etc. where the frequency could be absolutely forbidden.
3. Depending on 2. above, WPC will either intimate either that the case cannot be considered , or that the frequency allocation is feasible. Pl. note that the result can be different for different applications. That is to say that some application may be approved, and other rejected, depending on the site address. The decision is taken by a special committee called SACFA (Standing Advisory Committee for Frequency Allocation)
4. If the result of 3. is positive, then if the antenna is on a mast and at a height , site-clearance for mast height is separately required to be obtained from WPC.
5. The application for license is then accepted and processed . The applicant is has to take security clearance from the Internal Security Ministry. The end-user representative will be required to be present for security clearance from the Police authorities.
6. After the security clearance is obtained, the letter of "approval to grant of license" is issued. This letter contains the approved power, band, etc. and the amount of the annual license fee and royalty (typically about USD 2000 per year). This is not the final license. The applicant can then legally purchase the wireless product.
7. The applicant must then pay the annual license fee and royalty and provide the full equipment details . WPC then issues the final license valid for 2 years is issued.
The above process needs to be done for each and every enduser. There is no guarantee that all the applicants will be granted the license.

1. WPC Dealer Possession License

2. WPC Import License

3. WPC Demo License

TEC (Telecom Engineering Center):-

TEC (Telecom Engineering Center) is a Technical Group specially appointed by the Department of Telecommunications (Govt. Of India) and functions as a Government department.
Who needs TEC approval ?
Only products which will be connected to the DOT owned PSTN, ISDN, Leased Line etc. (like modems, telephones, fax machines, ISDN routers, EPABX…) need to be TEC- approved by the concerned trader/manufacturer of such products. Products that will not have any connection to DOT owned networks (like private operators’ lines, VSAT etc.) do not need approval by TEC.
TEC issues 2 kinds of approval :
1. Interface Approval - for products to be sold in general market for public use (modems, Fax, ISDN terminals etc.) .
2. GR Type approval -for products that will be procured by the DOT for use in implementing their Public Network (Cables, Exchange Switch etc.)
3. What is the requirement for TEC approval ?
For obtaining approval the following are the prerequisites.
a) The trader / manufacturer of the product must have his authorised distributor in India (in whose name the approval certificate will be issued )
b) The trader must have a valid status in respect of the necessary permissions to import and trade. If the trader is a company with foreign equity, the permission to trade must be granted by FIPB .
c) The product must meet all the technical specifications (refer to Annexure. 1) as per TEC. Two samples (2 nos.) of the product will be submitted for testing to TEC.
d) For GR Type approval, the applicant must have a full fledged support system for repairs, servicing etc. for the product. An “Infrastructure Approval” is additionally required to be taken prior to the product approval.
e) If the product is manufactured, and the applicant desires Interface Approval, Infrastructure approval is required to be taken.

What is the TEC Approval schedule?

a) Submission of Application with the following documents:
• Applicants details in prescribed “FORM A”
• Clausewise compliance to TEC spec sheet for the product. Each clause must be supported by test report from an accredited lab or by detailed documentary evidence. Click here for list of TEC specifications
• Technical manuals of the product with circuit diagrams and other details.
• Instruction manuals of product with trouble shooting guide etc.
• Product Brochure
• Letter from manufacturer authorising the applicant ( if the applicant is not the manufacturer)
• Legal undertaking
• Testing Fee

The TEC officials will undertake a complete study of the documents above and will ask for additional information in case required. Thereafter TEC will ask for submission of samples and will inform the applicant of the testing dates.
b) Submission of samples with prescribed “FORM B”
Both the samples will be tested in the TEC lab for compliance with the prescribed specs. (see Annexure 1) In case there is any failure, TEC will, at its own discretion, allow for minor adjustments in the product. However TEC will not allow any modifications in the lab. In case such modifications are required to be done, the application will have to be withdrawn and a re-application will be required to be done as in (a) above along-with the testing fees, after the necessary modifications are done.
For GR Type approvals, the tests are more stringent and have to go through environmental tests and field tests in addition to the interface tests. After successful testing, TEC will prepare the approval certificate.
If the product still does not meet the specifications, TEC will issue a rejection letter.
The applicant can always re-apply again after some more modifications. There is no limit to the number of re-applications for a product. TEC will charge their testing fees for each application.
c) Receipt of Certificate of approval from TEC
Usually the certificate is mailed to the applicant in a weeks’ time after completion of successful testing. d) Return of samples on submission of the following documents :
• Relevant photographs of the product
• Undertaking of retention of samples for future reference by applicant.
