Next-generation Wireless Networks will be As the wireless standards occupy larger parts of the spectrum with an ever-larger number of antennas, there is an opportunity to also use the communications spectrum for “imaging” the environment. Next-generation networks like 6G will be multi-function, i.e., use the same spectrum for multiple functions. In this talk, we will first briefly review our research contributions over the past decade that could play a role in developing multi-function networks. And then highlight our recent efforts to develop theoretical foundations to understand the tradeoff in multi-function networks.

One of the novel features of 5G is the local connectivity solutions and private networks for which some of the specific spectrum bands have been already allocated. 6G will target at developing mobile technologies at higher spectrum bands for mmWave bands and even sub-THz bands. When systems operate at higher spectrum bands, local networks start to make even more sense as the communication link ranges are drastically dropping due to harsh propagation conditions. In particular, when operating in indoor environments, private networks can achieve total interference isolation making adjacent networks co-existence straight forward and simple. This will open totally new business opportunities and can greatly accelerate digitalization of society. Property owners will be part of the value chain with dedicated networks customized for their own needs: hospitals, schools, shopping malls, factories, office buildings, private households etc. can have different offerings and capabilities of networks in the future. The global private 5G network market size was valued at USD 1.38 billion in 2021 and is expected to expand at a compound annual growth rate (CAGR) of 49.0% from 2022 to 2030. Currently, private 5G networks are non-public and not requested to allow roaming with MNOs networks. Towards 6G, the private network concept needs to be enlarged to enable also open local connectivity and roaming. The reason for this is both technical due to extremely high frequencies as well as the digitalization needs and expectations from the society. New players are needed with new investments speeding up digitalization of society. Furthermore, discussions on the technical superiority of 6G enabling up to Tbps peak datarates, cm level positioning, sub ms latency and ultra reliability at lower energy consumption etc., are also encouraging to focus on local connectivity solutions in innovative 6G developments. Evolutionary path of 5G solves larger area coverage needs also in the future – and local connectivity solutions will be part of this evolution.

We live in a data-driven world as everyone around has been telling us for some time. Everything is generating data, in volumes and at high rates, from the sensors embedded in our physical spaces to the large number of machines in data centers which are being monitored for a wide variety of metrics. The question that we pose is:
Dependability is the property that a computing system continues to provide its functionality despite the introduction of faults, either accidental faults (design defects, environmental effects, etc.) or maliciously introduced faults (security attacks, external or internal). We have been addressing the dependability challenge through large-scale data analytics applied end-to-end from the small (networked embedded systems, mobile and wearable devices) [e.g., CVPR-22, Eurosys-22, NeurIPS-20, Sensys-20, UsenixSec-20, NDSS-20] to the large (edge and cloud systems, distributed machine learning clusters) [e.g., OSDI-22, Sigmetrics-22, UsenixATC-21, DSN-20, UsenixATC-20]. In this talk, I will first give a high-level view of how data analytics has been brought to bear on dependability challenges, and key insights arising from work done by the technical community broadly. Then I will do a deep dive into the problem of configuring complex cloud systems to meet dependability and performance requirements, using data-driven decisions.
For the detailed part, I will show how distributed applications on the cloud can be configured for dependability and predictable performance even as the workloads are changing unpredictably. I will then discuss an exciting and emerging area of cloud computing called serverless applications on the cloud and show they can be configured for dependability and performance determinism.
