hello everybody,
I am currently serving and would most likely go for my masters after my service year, but I am having a hard time
trying to decide what course to study postgrad. I studied Electrical Engineering undergrad and I have serious interest in computing and communication systems, I also like e-business and management courses, but I dont which one to settle for.
After some research, I discovered the following courses but dont know which to choose, pls any one with any suggestions and advices with respect to their level of lucrativeness and profitability in Nigeria?

*radio and mobile communications
*broadband telecommunications
*computing artificial intelligence and IT
*information & Business systems
*e-business and information systems

Thank you all, I eagerly look forward to hearing form y'all. thanksssssssss!
