M.Tech Scope

IISC, Bangalore as their research facility is excellent. Otherwise IIT Delhi, Bombay, Madras are the ones.

Since you have already completed your PG in India, and since you have work experience it is better to apply for companies, which are present there rather than pursuing any courses. If you know any person who is living in Canada it would be easy for you to shift there and he/she could help you out in finding a job there.

Wireless communications and robotics courses are in ECE branch.

Scope of this course is vast. Seats are not specified. It could have been increased this year.
