2.4ghz legal india

时间:04-10 整理:3721RD 点击:
Can any one tell me what are the restriction on RF transmission in various bands in India (NOT HAM) without req. any license. Are small walky-talky, fm transmitters etc legal ? Upto how much power and what are the laws. I'd also like to know, What about ISM band ? FAP (Freq. Allocation Plan) document is very confusing. I can't understand a word of the cryptic language used. eg what does it means that ISM band at 2.4 GHz 'has been delicensed' ?

Go to biggest post office in ur town & enquire there about ur specific interest.

Wireless Planning Coordination (WPC) is the wing of Department of Telecommunications in India that looks after the Spectrum management in India. Notifications are posted on WPC site about the 2.4 & 5 GHz (ISM) band. Delicensing means till the notification was issued it required to get the licence for the use of 2.4 GHz and now it is not.

@palesha If that works, it mean ur not in India. :)
@VSWR Off course, I know the sites regarding the departments. When I talk of NFAP document it had to come from authorities however I said they are not easy to understand. Moreover they don't list what all I've asked.
@ricksidd, Thanks for informing abt delicensing However I am still looking answers to other questions.

abhilohli, if you give me the relevant portion of the NFAP, i would try to explain the meaning to you.

@Sidd

Its not any specific part of NFAP that I want to understand, I just want to know general things like how much power radiated is legal without req. any license in different bands say FM radio or TV VHF/UHF band (U know what freq. bands these cover) or ISM band etc... Because there are equipments that use these bands eg FM transmitters/MIC, private data link modems etc. I just want to know what part of RF spectrum & under what limitation, can I use WITHOUT requiring 'any' license (not even amature radio/HAM license).

-Thanks

abhikohli, Yes the Indian Spectrum usage is neither very clear nor comprehansive, however the important and most used bands are defined for their kind of usage and power permitted to be radiated.
Now, WPC site has a link for Rules and Regulations in which list of subordinate Legislation ( a bit complicated matter for simple things ) gives some of these permissions. For example, one abstrct of on eof the frequency usage is Now, if you have any particular information requirement, you write a letter to Jt. Wireless Advisor, WPC and hopefully you get the required information about the permitted usage and power.

2. ...if these are working in License free band its OK otherwise you have to get the license for usage and pay the licence fee for the link annually.
3. For most of the things don't worry yaar, there is no monitoring of usage per se. For academic purpose just experiment without interferring Licensed users, thats all...

Thigs looking much better now. Thanx sidd. Still anyone, any idea, say if I transmit in FM radio band (off course unused freq. say 89 Mhz). Legally , how much power can I radiate, considering if monitoring is happening ;) And how much bandwidth can I occupy. What about unused (E)GSM band ? (Is there any left ?). And ISM ?

Typical AM and FM radio stations operate at power levels up to 50,000 watts

One more query....
My previous comment was for licensed and legal transmission.
Does anybosy know, what is the limit of power level for without license transmission? Considering that it is legal for some power limit....

Yes thats exactly the info I am looking for.
