Full preparations have been made for 5G network in India. Spectrum has also been auctioned off, with two telecom giants like Airtel and Geo also seen tests and live demos of 5G. But in the midst of all this is a big question that has been suppressed nowhere. 5G is going to be very useful for the internet but it can also be just as detrimental for TV broadcasts. The 5G network can cause problems with the signal of the TV broadcasting and the quality can also be poor.
TV broadcasts use frequencies ranging from 3.7GHz to 4.2GHz that downlink from satellite to TV and what is special is that for 5G a frequency of 3.00GHz to 3.7GHz is selected. It will have a direct impact on 900 channels. In this regard, the Indian Broadcasting Foundation (IBF) has given a presentation to the Department of Telecommunications and the Ministry of Information and Broadcasting on the difficulties encountered in TV broadcasting from 5G spectrum.
Generally all C band satellites use frequencies of 3.7GHz and 4.2GHz for downlink and most TV channels operate between 3.7GHz and 4.9GHz. Satellite TV now starts at 3.7GHz and ends at 5G at this frequency. If this frequency is used for 5G then TV services will be affected.
Experts believe that up to 3.6GHz frequency should be allowed for 5G in India. An official of the Telecom Regulatory Authority of India said in a statement that telecom companies should use filters so that other companies do not get in trouble. However, the government has not yet clarified how many GHz frequencies will be used for 5G. But that being said, this will be from 3.3GHz to 3.6GHz.
Now the question is, if 5G network is started on this frequency, then what is the arrangement so that the services of satellite TV are not disrupted? The answer is that satellite TV will have to be shifted to more frequencies. Or you have to use a bronze pass filter in the cable which is a very confusing job.
