Introduction to Wireless

Enabling the Wireless Communications of Tomorrow

Wireless communication systems will be one of the biggest drivers of integrated circuit products over the next decade. IC technology, in turn, will continue to be the enabling factor for greater mobility, versatility and affordability in wireless applications. For wireless designers, key areas of technological development include basic semiconductor processes, digital signal processing, and radio frequency systems and circuits. TI is confronting the challenges in all of these areas to develop new IC products that will enable the wireless communications systems of tomorrow.

The only thing that seems to be restraining growth in the wireless industry is the high cost of using wireless services.

Twenty years ago, few would have predicted the revolution which resulted from the development of the personal computer in the late 1970s. It is hard to imagine, but the wireless revolution is an even more recent phenomenon. The question now is what will take this industry to the next level -- to make wireless products as pervasive for consumers as the telephone or the television. The answer is clearly technology -- technology to expand functionality and reduce costs.

The past decade has shown that the demand for wireless services is huge. The only thing that seems to be restraining growth is the high cost of using these services. Several key areas of technological development have fueled the wireless revolution and now have the potential to move it to the mass market quickly. These areas include:

Semiconductor materials and processing technologies. The drive to smaller, faster and cooler systems is being led by advances in transistor geometries and other aspects of IC manufacturing technology.
Digital signal processing. The prime enablers for digital communications, digital signal processors (DSPs) are confronting the specific needs of wireless systems for higher levels of integration and greater performance with low power consumption.
Linear/radio frequency (RF) electronics. High component counts and power consumption in radio subsystems must be reduced drastically. Some of the most important activity in the wireless industry is concentrating on developing integrated RF components.
System issues. Size, weight and battery life are important determinants of mobility in wireless systems. Emerging technologies such as speech recognition will also make future systems more versatile.
