A question about entering communication side of the military

[anonymous individual]

If one wants to obtain a university diploma before having any obligation with the military with the wish of entering the communication side, such as dealing with radios, satellates, or equipment, as a non-civilian, what degree should that person have?

Thank you for any reply in advance.

Please excuse my poor English.
