In today’s connected world, IoT devices are asked to do more than ever — often serving as a bridge between cloud services, smartphones, and dense networks of local sensors. This requires a seamless combination of wireless protocols: Wi-Fi for high-throughput data and cloud connectivity, Bluetooth for mobile pairing and provisioning, and Thread or Zigbee for low-power mesh networking. Increasingly, supporting multiple protocols in a single device has become an expectation, particularly across smart home, industrial, and healthcare markets, although the exact mix of technologies can vary by use case.
The multiprotocol challenge
Bringing several wireless standards into compact, battery-powered devices creates significant technical challenges. Wi-Fi, Bluetooth, Thread, and Zigbee all share the crowded 2.4 GHz band, which can lead to interference, signal degradation, and timing conflicts that reduce performance. Engineers must also coordinate protocols with very different demands — some latency-sensitive, others bandwidth-hungry — while keeping power consumption in check. Add the complexity of global certifications, and multiprotocol design quickly becomes one of IoT’s more difficult hurdles.
Why the demand keeps growing
Several trends are accelerating the move toward robust multiprotocol platforms. The Matter 1.2 standard is helping unify ecosystems across major smart home platforms, often requiring Wi-Fi, Bluetooth LE, and Thread support. Edge AI applications need both strong cloud connectivity and fast local responsiveness. And global deployments introduce the challenge of ensuring consistent performance across diverse networks and regulatory environments.
Reliability is just as important as compatibility. Many next-generation IoT devices benefit from dual-band Wi-Fi (2.4 and 5 GHz), which helps reduce congestion, improve throughput, and maintain performance in busier environments. While 2.4 GHz-only solutions remain sufficient for some cost-sensitive or low-power applications, dual-band capabilities offer an advantage where user expectations for speed and stability are high.
Real-world applications
The importance of multiprotocol support becomes clear in real-world applications:
Smart thermostats use Wi-Fi for remote monitoring, Bluetooth for simple smartphone setup, and Thread for efficient interaction with HVAC systems and other devices.
Video doorbells and security cameras benefit from dual-band Wi-Fi for reliable video streaming while balancing battery consumption.
Voice-activated speakers and hubs often require simultaneous Wi-Fi and Bluetooth connectivity, while processing commands locally with minimal latency.
Outdoor AI security devices, such as battery-powered cameras, must maintain strong, low-power connectivity
Industrial IoT systems, from asset trackers to predictive maintenance sensors, rely on rugged, secure, and efficient multiprotocol performance in demanding conditions.
Without well-integrated connectivity, these devices risk shorter battery life, dropped connections, or inconsistent user experiences.
Platform-level integration
To address these challenges, the industry is steadily moving toward system-on-chip (SoC) platforms that support multiprotocol operation natively. By integrating RF, scheduling, power management, and security into one architecture, these solutions enable smarter time-slotting between radios, greater hardware efficiency, and advanced coexistence strategies. The result is smaller, more capable, and cost-effective devices.
Examples like InnoPhase IoT’s Talaria 6 Family demonstrate this approach, integrating Wi-Fi 6, Bluetooth 6.0, Thread, and Zigbee in a single, ultra-low-power SoC with support for both 2.4 GHz and dual-band operation. These platforms typically feature digital radio architectures that simplify RF design while maintaining strong performance, ARM Cortex-M33 processors for sensor management and edge AI, and comprehensive security protections including secure boot, hardware encryption, and tamper resistance.
Modern multiprotocol SoCs are also designed with future connectivity standards in mind, often supporting emerging features like Wi-Fi 7’s Multi-Link Operation. With development tools, reference designs, and pre-certified modules, these platforms help accelerate development and reduce time-to-market.
Final thoughts
As IoT expectations grow, support for multiple wireless protocols and, increasingly, multiple bands are becoming a central design requirement. Success demands more than simply combining radios—it requires platforms optimized for coexistence, power efficiency, and edge intelligence.
With scalable, secure, and low-power foundations, next-generation multiprotocol SoCs enable the next wave of smart thermostats, doorbells, voice hubs, remote cameras, and industrial sensors to connect reliably and operate efficiently in today’s crowded wireless environments.
