HD-FDD: Optimizing IoT Connectivity for 5G eRedCap

The Internet of Things (IoT) market is expanding rapidly, with device shipments growing at 22% annually from 2020 through 2030. As IoT deployments scale to millions of devices worldwide, power efficiency, cost optimization, and global compatibility become critical challenges. Traditional cellular technologies, designed for different use cases, often struggle to meet these unique requirements, resulting in increased complexity, higher costs, and shorter battery life.

This white paper explores how Half-Duplex Frequency Division Duplex (HD-FDD) technology is transforming the IoT landscape. Already the standard for LTE-M and NB-IoT networks worldwide, HD-FDD allows devices to transmit and receive data at different times rather than simultaneously, streamlining device design while maintaining signal integrity. The paper dives into how this proven technology can also unlock significant benefits for 5G eRedCap deployments, where power and cost constraints are even more critical. By adopting HD-FDD, device manufacturers can reduce component costs, lower power consumption, simplify manufacturing, and deploy a single hardware design globally.

For developers, engineers, and decision-makers working on next-generation IoT devices, understanding HD-FDD’s role in 5G eRedCap is essential. This white paper provides practical insights into overcoming the limitations of traditional cellular approaches and future-proofing your IoT strategy with efficient, cost-effective connectivity solutions tailored for massive scale deployments.
