I have planned to buy Sierra Wireless module HL6528. which works on 850/900/1800/1900 MHz. Do I need to buy license from Indian government to use the module in this frequency in India?
Which are the license free freqencies ranges in India?
i dont think you need specific import license. you may need to ask the manufacturer if the instrument with HL6528 is certified to use it in india/chennai. if its not, you can ask the manufacturer to certify it for you or you can certify yourself.
