Sohra (Meghalaya), Oct 24 – Researchers at the National Institute of Technology (NIT) Meghalaya and the North Eastern Space Applications Centre (NESAC) are collaborating on a groundbreaking project aimed at enhancing 5G and 6G connectivity in Sohra, recognized as the rainiest place on Earth.

Following their relocation to a permanent campus earlier this year, the researchers expressed both fascination and frustration with the unique characteristics of rainfall in Sohra, located in the East Khasi Hills district. A scientist involved in the project noted, “The size and intensity of rainfall here are unlike anywhere else in the world. It disrupts communication signals and challenges existing network models.”

Dr. Anup Dandapat, Dean (Academic Affairs) at NIT Meghalaya, emphasized the goal of leveraging Sohra’s extreme weather conditions. “Instead of seeing heavy rainfall as a barrier, we want to use it as a natural laboratory,” he stated. The research focuses on understanding how raindrops interact with high-frequency signals, which could lead to the design of more adaptive and resilient networks, not only for Meghalaya but also for other rain-prone regions.

The study aims to investigate the impact of large raindrops and frequent rainfall on signal transmission, with the objective of developing rain-resilient communication systems. This advancement is particularly crucial for remote and hilly areas that experience connectivity disruptions during the monsoon season.

Sohra, formerly known as Cherrapunji, continues to captivate both poets and scientists alike. For the NIT and NESAC teams, each rainfall event serves as a valuable data point in their mission to enhance technology’s resilience against extreme weather.

In a separate achievement, NIT Meghalaya researchers have successfully designed and fabricated the state’s first integrated chip (IC) under the Special Manpower Development Program (SMDP) of the Ministry of Electronics and Information Technology (MeitY). The team, consisting of faculty members Dr. Prabir Saha, Dr. Shubhankar Majumdar, and Dr. Pradeep Kumar Rathore, along with PhD scholars Geetima Kachari, Parishmita Goswami, and Deibaphira Suchiang, developed a Finite State Machine (FSM) chip. This chip was fabricated at the semiconductor laboratory (SCL) foundry using 180-nanometre process technology.

Designed for precise control in irrigation systems and tensiometers, the chip has significant potential applications in advancing India’s agricultural technology sector. It was presented to Prime Minister Narendra Modi at the SEMICON India 2025 summit, showcasing the importance of academic research in bolstering India’s technological self-reliance.

Dr. Dandapat highlighted that these dual achievements—addressing monsoon connectivity challenges and pioneering IC design—underscore the burgeoning research ecosystem in the Northeast and the region’s contribution to the vision of a Viksit Bharat. The NIT team is currently working on a second chip, which has also been submitted for fabrication. This upcoming chip aims to facilitate agricultural development by comparing various environmental factors to yield accurate measurements for monitoring plant growth.
