TI Digital Signal Processing Solutions for Wireless Technology

Given the requirements and future trends of wireless systems discussed in the preceding sections, four technology drivers emerge as the basis on which future progress will be determined.

Semiconductor technology will determine the levels of integration, power consumption and system performance that will be achievable.
DSP technology will continue to be the key baseband technology on which digital wireless systems are built. DSP solutions will grow in importance as the partition between the radio and the baseband subsystem gradually moves to drive more and more functionality into the signal processor.
RF components and architectures will drive much of future system cost and volume reductions. A key issue will be where the system is partitioned between the RF and baseband subsystems.
Batteries, through their size, weight and charge lives will ultimately determine how far the wireless revolution can go.

Wireless Systems in the 21st Century

Today's dream of a single-chip wireless engine may be available within a decade, making it possible to integrate the working electronics of a wireless instrument into almost any form factor imaginable. Wireless real-time communicators or store-and-forward devices will appear that can be carried or worn unobtrusively -- perhaps as jewelry. The vision then is of a wireless future where the guts of a subscriber instrument can be housed in a package as small as a ring, perhaps with the microphone and speaker in a separate package.

Technological developments in semiconductor processes and materials, DSPs and RF systems are hurrying along the development of advanced wireless applications. Batteries, speech recognition, and other important hardware and software technologies are also contributing to the growth of these applications. With its expertise in many of these technologies, TI is taking a leading role in enabling advanced wireless products, helping to make "anywhere, anytime" communications a reality in the 21st century.
