First of all, I must appreciate your stand which you are likely to take up.
Since your Engineering degree is a graduate degree, so there exists a scope for your persuasion in B.Ed degree.
In this context, I would recommend you to have a regular degree course of B.Ed from a recognised university in order to enhance your chance to be selected as a teacher. However, you have to show in your application - form that you have had an exposure in teaching line for at least two years. The other option, in this regard would be to take up this course from IGNOU- a known reputed University providing education as a distance mode. The most advantageous part by going through distance mode in IGNOU is the management of your time if you want to persue your job in your related field.
The other alternative is to take up M.Tech course in Electronics and Telecommunications from a recognised University and by clearing the NET test, you can make your entry in the field of education as a lecturer in a Government Engineering college. NET is the essential criteria for absorption in Government Engineering colleges provided one has not pursued a doctorate degree in one's stream. This condition is waived for an aspirants having a doctorate degree in the relevant field. In that way, you would be enjoying decent pay- packet by joining a Government Engineering College. However, in a private Engineering college, such condition is not required. Even by doing BE in a particular stream is sufficient to apply in such Institutions and you will be offered the post of Lecturership after your satisfactory performance in the Interview.
