The Internet of Things (IoT)—the network of connected “smart” devices that communicate seamlessly over the Internet—is transforming how we live and work. At farms, wireless IoT sensors can transmit information about soil moisture and nutrients to agricultural experts across the country. IoT alarm systems, equipped with batteries that last for years, provide homeowners with long-term protection. Wearable fitness devices—for both people and pets—can monitor activity levels and provide feedback on heart rate and respiration. Although these applications serve different purposes, they all share one characteristic: dependence on strong connectivity.
