Respected Dana,
Although I live in India but being a professional I am following telecom market growth around the world .
I personally feel that if you are talking about money , then one can make really good money while working in
Arab world as the telecom sector is growing . More over as new technologies are rolling out there in Arab world, one would really get a good exposure and will be able to learn more thing's besides earning . So in other words you will earn while you learn and being professional it's really good. It's kind of win win situation may be that's why many RF Engineers are looking for jobs in GCC.
