Towards 6G Evolution: Three Enhancements, Three Innovations, and Three Major Challenges
Over the past few decades, wireless communication has witnessed remarkable growth, experiencing several transformative changes. This article aims to provide a comprehensive overview of wireless communication technologies, from the foundations to the recent wireless advances. Specifically, we take a neutral look at the state-of-the-art technologies for 5G and the ongoing evolutions towards 6G, reviewing the recommendations of the International Mobile Communication vision for 2030 (IMT-2030). We …

Beamforming Optimization for Active RIS-Aided Multiuser Communications With Hardware Impairments
In this paper, we consider an active reconfigurable intelligent surface (RIS) to assist the multiuser downlink transmission in the presence of practical hardware impairments (HWIs), including the HWIs at the transceivers and the phase noise at the active RIS. The active RIS is deployed to amplify the incident signals to alleviate the multiplicative fading effect, which is a limitation in the conventional passive RIS-aided wireless systems. We aim to maximize the sum rate through jointly designi…

What-if Analysis Framework for Digital Twins in 6G Wireless Network Management
This study explores implementing a digital twin network (DTN) for efficient 6G wireless network management, aligning with the fault, configuration, accounting, performance, and security (FCAPS) model. The DTN architecture comprises the Physical Twin Layer, implemented using NS-3, and the Service Layer, featuring machine learning and reinforcement learning for optimizing carrier sensitivity threshold and transmit power control in wireless networks. We introduce a robust "What-if Analysis" module…

This ranking biases toward places lots of people walk/bike to begin with. Tons of pedestrians/cyclists at Market & Octavia = tons of opportunities for injury.
Very few people walk or bike near 19th Ave & Sloat, but it still made the citywide top 10. So if you're wondering where, if *you* decide to walk there, you'll have the highest risk of getting hit, 19th Ave & Sloat is by far the most dangerous on the list.
