Telecommunications, in my opinion, has a good market as far as employment is concern. It is still in its infancy as a lot of new technologies are being invented. However the downside is if you are in this industry you'll have to keep up with the technologies to remain competitive (kinda like the IT industry in some ways). Of course you dont have to work for the big telcos to be in this industry, you can be a supplier, a vendor, a content provider, sub contractor, etc.
