I dont agree telecommunications bhanne bittikai scope limited huncha bhanera. Telecommunications bhanne bittikai telecommunications matra bujhidaina. Telecommunications itslef has different communications.

Like I did my master's in microelectronic and telecommunications. My communications subject were optical fiber, antennas, radio frequency, telecommunications, Advanced signal processing, EMC etc.  Most of these subejects didnt focussed on telecommunications.  So go by subject. Kun kun subject sikaucha tyo hera rather than just the name telecommunications because name can only be decieving.
