The Department of Electronics and Communication Engineering is pleased to announce the publication of a significant research paper by Dr Anirbhan Ghosh, Assistant Professor, exploring MIMO channel capacity at high frequencies (300 GHz), which holds great potential for beyond 5G and 6G networks. The paper “MIMO Channel Capacity Measurement in Open Square Hot Spot Access Scenarios at 300 GHz” published in the Q1 journal IEEE Wireless Communication Letters, investigates data transmission in three different line-of-sight (LoS) scenarios and contributes to building the next generation of communication networks, which will have a significant positive impact on society by improving connectivity, supporting technological advancements, and promoting economic development.
Abstract
This letter explores the possibility and effectiveness of using multiple communication paths for futuristic outdoor networks, focusing on three scenarios: clear line-of-sight (LoS), partially obstructed line-of-sight (OLoS), and completely blocked line-of-sight (NLoS). A study was conducted at a high frequency of 300 GHz to measure how many useful communication paths are available for transmitting data simultaneously. Based on the results, the average data transmission capacity for these paths was calculated, both with and without the help of passive reflecting surfaces (PRS). The findings show that using multiple antennas significantly boosts the average data capacity, and PRS further enhances this improvement.
Practical Implementation of the Research
The results align with the design of high-frequency, ultra-high-speed, low-latency, reliable communication envisioned for several futuristic applications beyond 5G and 6G Networks.

Dr Ghosh plans to extend his efforts to other communication scenarios for a similar study. He opines that generating appropriate channel models, coverage design, etc., for the explored scenario would also be an exciting study.
