Comprehensive coverage of wireless signal propagation effects including attenuation, shadowing, fading, and interference. Explains frequency-selective fading, Doppler spread, coherence bandwidth, coherence time, and their implications for bit rate adaptation protocols.
Presents PHY-aware link layer design with SoftPHY hints for bit error rate estimation and streaming PHY interface. Discusses SoftRate bit rate adaptation protocol and SoftCMAP MAC protocol that leverage cross-layer information for improved wireless throughput.
Introduction to wireless communication networks covering challenges in wireless data throughput improvement. Discusses signal propagation, SNR fluctuations, wireless channel complexities compared to wired networks, multipath fading, interference issues, and PHY/link layer interactions.
The paper analyzes performance, bottlenecks, and optimization opportunities for UPF designs in 5G using network function virtualization. It benchmarks kernel-bypass, smartNIC, and programmable switch deployments, with a focus on throughput, power efficiency, and scalability constraints in serving millions of subscribers.
Witals is a system providing causal diagnosis of WiFi network performance problems from an access point’s perspective, using comparable metrics termed WiFi vital statistics. It diagnoses multiple simultaneous causes such as interference, overcrowding, and slow clients, enabling system administrators to identify root causes effectively. The paper includes comprehensive evaluations with real and controlled WiFi deployments
