V. and I were talking about 3G mobile phone yesterday when he suddenly mentioned WiMax. What is WiMax? It is an acronym that stands for Worldwide Interoperability for Microwave Access, a certification mark for products that pass conformity and interoperability tests for the IEEE 802.16 standards.
With WiMax, one can also send and receive large files of video, photo, or music in a long distance, approximately 50 kilometers. It is useful having a cell phone integrated with this function in big cities. As for 3 G, one can also do the aforementioned things and even watch news or movies.
Now, the question is if WiMax or 3G provides the access of Internet, then one can also use free online telephone service such as Skype to make calls. What will happen with all those mobile phone companies? For those who are metropolitans, wouldn’t it be so convenient to use the free Internet phone to call friends or even clients any time and any where?
How would those mobile telecommunication corporations deal with this situation? Maybe they will have to increase the charge of the Internet service on cell phone. Although there are still a few years to go, I’m sure with the advance of technology, we will soon be able to use either WiMax or 3G in many places…
