Term: 1. July 2022 - 30. June 2025Funding source: BMBF / Verbundprojekt
Motivation
The increasing number of networked devices and sensors, the "Internet of Things" (IoT), enables diverse and new applications. However, it is also generating a rapidly growing volume of data. Processing data at its point of origin (edge computing) helps to deal with it efficiently. Edge computing strengthens the functionality, sustainability, trustworthiness and cost-effectiveness of electronic applications through the use of artificial intelligence and networking. The goal of the OCTOPUS projects is to provide application-specific, highly innovative electronics to unlock these benefits.
Goals and strategy
The aim of the project is to create the technological basis for an AI-supported, flexible, efficient and scalable multi-access edge cloud (MEC) with which future mobile networks can be realized. This should have low latency, high frequency agility and high data rates. To this end, analog and digital circuits will be designed, built and verified to linearize the radio signals to be transmitted using a centralized AI-powered algorithm. New approaches will be used to achieve the energy efficiency, frequency flexibility, bandwidth, scalability and cost efficiency requirements of the system. The focus is on new power amplifier architectures based on gallium nitride (GaN) and a new overall architecture that reduces the complexity of the MEC.
Innovations and perspectives
The MEC can be used to build powerful and efficient mobile networks that support complex applications, for example from industry or mobility. A special special focus is on the use of particularly energy-efficient technologies in order to promote not only digital progress as well as promoting the European Green Deal.

The increasing number of networked devices and sensors, the "Internet of Things" (IoT), enables diverse and new applications. However, it is also generating a rapidly growing volume of data. Processing data at its point of origin (edge computing) helps to deal with it efficiently. Edge computing strengthens the functionality, sustainability, trustworthiness and cost-effectiveness of electronic applications through the use of artificial intelligence and networking. The goal of the OCTOPUS projects is to provide application-specific, highly innovative electronics to unlock these benefits.
Goals and strategy
The aim of the project is to create the technological basis for an AI-supported, flexible, efficient and scalable multi-access edge cloud (MEC) with which future mobile networks can be realized. This should have low latency, high frequency agility and high data rates. To this end, analog and digital circuits will be designed, built and verified to linearize the radio signals to be transmitted using a centralized AI-powered algorithm. New approaches will be used to achieve the energy efficiency, frequency flexibility, bandwidth, scalability and cost efficiency requirements of the system. The focus is on new power amplifier architectures based on gallium nitride (GaN) and a new overall architecture that reduces the complexity of the MEC.
Innovations and perspectives
The MEC can be used to build powerful and efficient mobile networks that support complex applications, for example from industry or mobility. A special special focus is on the use of particularly energy-efficient technologies in order to promote not only digital progress as well as promoting the European Green Deal.
