It depends on the course structure followed in your institution. For the first three years--assuming this is a 4 year bachelor's program in engineering--you do electrical science, control systems, and other important courses. In the fourth year or end of third year, you can chose to do more communications-related courses in EC or electrical-engineering courses (advanced control systems, microelectronics, digital signal processing, power systems, electromagnetics, microwaves/antennas, radar systems, instrumentation).
In India, for example, most students opt for Computer Science cold (if they can) and then for anything else, the preference order being EC and then EE for some weird reason (perhaps companies in the telecom arena prefer or consider EC people as they can be directly moulded to suit their workforce as opposed to EE people who have a wider course experience usually and hence might not be willing to work on software per se). I am told that EC has a higher rate of occupancy as does CSE and so a socially higher prestige value.
As your decision hinges on these options, you should get hold of the ENTIRE course list for both these programmes and then decide what you want to do. Mind you, academically, both branches (and ALL branches) are good...so you should ask yourself which one YOU want to chose rather than which is the better one :-).
Which college is this?
but I am just an undergraduate so I would say keep posting on these forums as there are many experienced people who can give some nice advice.
