: Early development of algorithms that adjust power and bandwidth based on channel conditions.

The 1990s saw the rapid growth of mobile communications, with the introduction of digital cellular networks and the first wireless local area networks (WLANs). Feher's contributions to the development of mobile communication systems were instrumental in shaping the industry. His work on wireless modems, which enabled high-speed data transmission over wireless channels, paved the way for the widespread adoption of mobile internet.

: Unlike purely theoretical textbooks, Feher provides a "down-to-earth" treatment of R&D, design, and testing of system components. Who Should Read It?
