The 1990s marked a transformative decade for Semtech as the company executed a strategic pivot from its historical dependence on military and aerospace markets toward broader commercial opportunities. This period of reinvention established Semtech as a significant player in the protection technology and analog semiconductor landscape, creating the foundation for its future as a diversified technology leader.

Semtech Corporation in the 1990s: Strategic…Over the past decade, solar photovoltaic technology has evolved from a niche market to becoming the world's leading clean energy source. As installations scale, operators face rising costs, technician shortages and complex monitoring demands. With the O&M market projected to reach $9.48B by 2025, the employers report workforce gaps and over half seek cost reductions. Yet, fewer than 1% of systems have real-time monitoring in place. To meet these challenges, the industry must embrace predictive maintenance and smarter infrastructure enabled by easy to install and maintain, long-range communication technologies like LoRa®。

Semtech in the 1980s: Crisis, Resilience and…Beyond Basic Monitoring: The Intelligence Revolution
While Parts 1 and 2 explored current applications of LoRaWAN® in crop management and livestock monitoring, the true revolution lies in the intelligent systems being built on top of this robust connectivity foundation. Through integration with analytics platforms, farmers can spot trends, predict yields and quickly identify anomalies. These capabilities help improve resource efficiency, boost productivity and enhance the stability of agricultural operations.

Smart Agriculture Revolution: Part 2 - Smart…The Agricultural Revolution is Digital
Agriculture faces unprecedented challenges in the 21st century. With the global population expected to 到 2050 年将达到近 100 亿, agricultural processes involving food production will have to increase their output by 70 percent by 2050. Climate change, resource scarcity and the need for sustainable practices are pushing farmers toward "precision agriculture" or "smart farming" solutions。
