Speciality Change

Dears

I am not sure if this place is the right place for asking such questions. I searched the forum and I found this place to be closest for asking my question.

I do apologize in advance if I am asking the question in the wrong place.

I have a BS in Electrical Engineering and I work for a Major Airline as an Avionics Engineer.

Currently, I am in my last year in doing my Master in Computer Engineering.

I am planning to do my PhD in Communication specialty Networking and Wireless Networking.

I have a good background in Computers. As a matter of fact I am Web Developer (Freelancer). Trust me I am not a novice. I built website on 99% standards.

I do appreciate any help, comments and things to read. It is easy for someone who his/her background is Communication to PhD in Networking and Wireless Networking but it might be a hard for someone like me.

Thank you,
