Coexistence Analysis of 5G and Satellite Networks at 3.5 GHz Frequency

As the latest mobile broadband technology, 5G technology has entered Indonesia and it has influenced the demand for the use of unrenewable source frequency spectrum. In Indonesia, 5G technology is being planned to use the 3.5 GHz frequency spectrum to meet the traffic demand. However, this frequency has previously been filled by satellites that were previously in operation which incidentally is the C-band txpd. In this case 5G must be able to coexist with existing C-Band users so that problems do not arise in the future and this is closely related to the calculation of prices and aspects of its economic business. The method used so that coexistence can occur between 5G and C-band users who have operated previously is by reframing C-band tape, by deactivating transponders that have been empty because they have been moved and the allocation of 20 MHz guard bands and an additional 180 MHz released for auction. Coexistence of these two technologies can occur, 5G can occupy the available slots. The reallocation of 3. 4-3.8 GHz will benefit many parties including the government, satellite operators, which is because the NPV is positive by comparing the price of the 2.3 GHz band license, 5G operators and application developers that is because the spectrum position is worthy of consideration, and consumers because of the possibility of affordable prices for the use of 5G networks in this spectrum.
