Hello there, since you're mentioning that you are specializing in communications, I would assume you are leaning more towards electronics especially RF stuffs. I would say your future are bright indeed if you willing to step down in Penang.
For RF communications, there are a few big MNCs that you can pursue such as Keysight and National instrument. These company are pioneer in creating and manufacturing electronic test and measurement equipment. They are the one that supply equipment that measure and characterize your devices with LTE or 5G. They are also the key players in 3GPP organization that defines 3G, 4G and 5G standards.
Besides RF if you are willing to branch out, you can learn more about field-programmable gate array (FPGA), VLSI, Verilog and stuff and you can pursue your career in IC design in maybe Intel, AMD, Western Digital, Micron, Nexperia etc..
Still not convincing enough? Learn more about computer machine vision in your uni and land yourself a career in Vitrox, Cortex robotics, Aemulus etc. They supply equipment to inspect IC or PCB end product. As the world electronic demand increasing every day, so does company that makes inspection system

You like hardware design? You can approach Jabil or Plexus where they are the ODM of some audio product that u can see in the market and medical equipment.
There are even more big RF companies that I did not mention above. If your uni allows you to take elective subject in your 4th years (i.e. assuming you are in a 4 years course), proceed to take machine vision, and IC design related subject.
tldr: Future is bright 
Anyone who are clueless and not comfortable to discuss in the public can PM me as well.
Thanks for a very insightful info, will share out.
