Modern wireless devices face increasing challenges as more wireless technologies compete for limited signal space. Sudhirkumar Prajapati addresses these challenges through advanced semiconductor wireless chip design, focusing on how devices communicate in crowded environments.
As the director of WiFi Systems Design at Infineon Technologies in San Jose, California, Prajapati leads global development teams across the USA, India, and Taiwan. His work gains significance as Internet of Things (IoT) applications expand throughout healthcare, urban infrastructure, smart homes and vehicles, where reliable wireless connectivity directly impacts critical operations.
Advancing IoT Technology
Sudhirkumar Prajapati’s work in wireless signal management, such as those in wireless chip design, has improved how wireless devices interact. His solutions enable smartphones, tablets and IoT devices to maintain multiple wireless connections simultaneously, such as streaming video while using Bluetooth headphones or using WiFi hotspot through cellular, without signal degradation. This technology extends to critical IoT applications, from medical monitoring devices that require constant, reliable connections to smart city sensors that manage traffic flow and energy distribution.
Through his leadership roles at Broadcom, Apple, and Infineon, Sudhirkumar Prajapati has developed wireless chip features that now power millions of consumer devices. His work on power efficiency has significantly improved, with new techniques reducing WiFi chip power consumption by 68% during standard operations and 33% in power-save mode. These improvements prove especially valuable in battery-powered IoT sensors and remote monitoring systems that must operate for extended periods without maintenance.
His work is particularly beneficial as the wireless chip design sector continues growing, projected at 8.36% annual growth from 2025 to 2030. Smart manufacturing facilities now deploy hundreds of sensors to monitor equipment performance and predict maintenance needs. On the other hand, smart agriculture systems use networks of soil moisture sensors and automated irrigation controls, and smart buildings use wireless systems to integrate climate control, security, and energy management.
Technical Innovation and Implementation
Sudhirkumar Prajapati’s research addresses fundamental challenges in wireless communications. His signal management protocols create designated time slots for different wireless signals, similar to traffic control systems. This approach proves particularly valuable in IoT environments, where millions of devices must communicate reliably while minimizing power consumption. For example, medical devices, patient monitoring systems, and asset tracking tags in smart hospitals must coexist without interference.
His work combines multiple approaches to improve wireless performance, including optimized antenna placement, advanced frequency management, and intelligent timing systems. These methods allow devices to maintain strong wireless connections and performance while conserving battery life. This is crucial for IoT deployments in hard-to-reach locations like industrial sensors in manufacturing plants or environmental monitors in remote areas. To implement these methods, Mr. Prajapati has done extensive study of WiFi, Bluetooth and LTE signal interference through complex test setup for achieving improved coexistence performance. His patented methods (US9131519B2, US9100108B2, US9420600B2, US10880884B2) are implemented in various smartphones, tables and IoT devices and currently in use worldwide.
Current developments focus on WiFi7 technologies, specifically multi-link operation (MLO), power optimization and multi-radio coexistence advancement. MLO enables devices to communicate across multiple frequency bands simultaneously, increasing data throughput, reliability and reducing latency in complex wireless environments.
The Future of Wireless Communication
Sudhirkumar Prajapati leads the development of next-generation wireless architectures, preparing for future simultaneous transmit-receive capabilities in IoT devices. This work involves creating new interfaces and hardware configurations to support increasingly sophisticated wireless communications, essential for applications like autonomous vehicles, smart homes and smart grid systems.
His team develops next generation wireless coexistence methods, fast wireless band switching and adaptive power management systems that respond to real-time network conditions. These advances become crucial as IoT deployments grow more complex, requiring performance and power efficiency. And as IoT applications expand, Mr.Prajapati’s research focuses on enabling new capabilities while improving existing ones. His recent work examines automotive systems and wireless coordination challenges, developing vehicle-to-infrastructure communication and automotive wireless solutions to support complex infotainment use cases and smart traffic management. He is also developing a technique to optimize overall power consumption of WiFi-BLE Coexistence connectivity solutions for improved battery life of IoT devices using PAwR (Periodic Advertisement with Response).
Sudhirkumar Prajapati’s solutions will particularly benefit large-scale IoT networks, enabling applications like factory predictive maintenance, efficient energy management in commercial buildings, automated inventory systems in retail environments and smart home applications.
