SiKora

Sichere Kommunikationsräume

* PROJECT IS FINISHED

System Design

An innovative integration of SDR as DU and optical front-ends as RU.

Functionalities

Data Transmission

Facilitates reliable data exchange through LiFi communication channels.

Handover

Maintain uninterrupted connectivity during seamless transitions.

Control Channel

Dynamically adjusts amplification stages to balance energy efficiency and channel conditions.

Testbed Architecture

A modular framework to evaluate and enhance LiFi communication within Open RAN architecture.

Web Dashboard

Enables handover and data rate demonstrations, showing signal strength, active AP, and control channel adjustments.

Resilience to External Attacks

Demonstrating the resilience of the LiFi channel, requiring jammers to be within a few centimeters to disrupt signal integrity.

Table: jamming distance by peak-to-peak voltage – 300 mV under 22 cm, 500 mV under 27 cm, 700 mV under 30 cm
