The days of Voice Communication are coming to an end. In fact it has been happening in the background all along. It is Digital Replacing Analog Everywhere. Voice is now data. In the future Voice Communication is just an App you need to buy as an option.
Whatever the struggle between technologies, The future communications will be just Broadband Wireless Devices with Voice, Data and Web all in one. The intermediate technologies we see today, the Transitional Technologies are part of a Large Learning Curve. The future may be more of Optics, WiMax and more like Any Device can do Anything. Not Convergence but more an Intermeshed Collage.
This RF is also a Tough Science and needs Authentic and Highly Skilled Engineers to design and develop the technologies for the future. The Budget of the Average consumer will be less, the appetite enormous. The Business Models complex and very challenging. The customer potential is 100% and it will work only if it is affordable and planned carefully. It is not as easy as it looks.
With the Wi-Fi and WiMAX becoming essential in Intranet and Internet Networks, and as new low power consumption tablets, netbooks and webbooks become commonplace; RF Microwave learning is important for designers.
It is almost like, every person is a potential user for a Handheld Computer. Which is not only a communicator but more important, News, Knowledge and Information is at his fingertips. This is an empowerment that makes a better worker, student, citizen or a businessman.
