Druid Software to partner with siticom for private 5G solutions. Initial large-scale deployment for a Research Institute in Germany's southern region of Bavaria Dublin and Weiterstadt, 19th of November 2020 Druid Software and siticom GmbH partner to deliver 5G wireless connectivity for a wide variety of Industry 4.0 vertical use cases in Germany such as manufacturing, automotive, healthcare and the agricultural sectors. Enhanced mobile broadband (eMBB), Massive Machine Type Communications (mMTC), and Ultra-Reliable Low Latency Communications (URLCC) will deliver a next-generation, future proof Industry 4.0 solution. 5G technology in the enterprise market is booming since the German Federal Regulator Bundesnetzagentur (BNetzA) awarded dedicated 5G spectrum licenses to industries that can be utilized to build locally managed, reliable, secure, and highly scalable private networks. 5G Non-Public Networks (NPN) networks will provide new levels of increased high-performance and coverage but also accurate distributed timing and synchronization for industrial applications and indoor and outdoor real-time proximity positioning and tracking. The Druid Raemis core platform is a 3GPP compliant 4G/5G core network with unique features designed specifically for enterprise critical communications. For example, the platform is differentiated by its ability to easily prioritize and “slice” devices while providing them with a guaranteed quality of service. Interoperability with any small cell RAN vendor, with 25x 5G small cells tested with Raemis to date, gives partners greater options to choose from indoor or outdoor specialists. Raemis scales up as easily as it scales down, enabling the setup of small or very large private networks. Raemis can be deployed on edge hardware devices or in high dependency cloud native environments. This flexibility is key for certain highly resilient mobile use cases or customers who do not want their data on the public cloud. Built on an open REST API, Raemis provides easy integration to enterprise critical applications and makes private networks simple to use and manage with a user-friendly dashboard. Private 5G networks empower enterprises to modernize and improve, allowing them to finally implement their own high performing wireless networks.

CONSTRUCTION KIT FOR ALL INFRASTRUCTURE PLANNING PHASES PLANNING SERVICE CIVIL ENGINEERING Modular planning service: Our flexible approach offers tailored solutions, e.g. for fiber optic expansion. With prefabricated modules and standardized processes, we can implement projects time- and cost-efficiently without compromising on quality. From design and approval planning to detailed planning and documentation, we are at your side. Our experienced experts use state-of-the-art GIS technologies to optimize your connection points, routes and housing locations. We also take care of approval procedures and communication with stakeholders. A fully digitized approach in our construction kit for planning services enables us to provide efficient coordination and documentation. Our experience in planning ensures that every detail is taken into account, e.g. to build a reliable and high-performance network. We optimize routing, select the best locations for distribution points, and thus ensure efficient and stable connectivity. VIEW SERVICES USE OUR MODULAR SYSTEM IN EVERY PLANNING PHASE PLANNING SERVICES Services DESIGN PLANNING In this phase, GIS planning with connection points, backbone connection, clustering and route centerlines with initial optimization of the course routes, quantity determination and overview map takes place . All early planning phases of the expansion projects are optimized in a basic module and additional modules such as surface survey and address clearing can also be added. APPROVAL PLANNING Taking into account the approval processes, an optimization of the locations and the routing takes place in this phase. All application documents are created and application returns are followed up . In addition to the basic module, further modules can be added, e.g. the incorporation of official requirements into the system. FINE PLANNING In this phase, pipe and fiber planning takes place in GIS-SW. Splice logs and material quantity lists are also generated . In addition, differences between self-supported and subsidized expansion projects, different map layouts and formats of the implementation documents can be taken into account. DOCUMENTATION Complete digital documentation in a GIS of your choice . CONSTRUCTION BOX TURNKEY AND CIVIL ENGINEERING We offer various realization models, gladly provide for the processing of the entire range of services from one source, in which we take over control, planning, documentation services and construction accompanying services for our construction executing partner companies. ​ The construction kit as PDF download contains in detail all additional modules that we offer for each planning phase. Contact us, tell us in which planning phase you need support and together we will find the right modules for you! DOWNLOAD CONSTRUCTION KIT CONTACT US OUR GIS EXPERTISE TOOLS In our construction kit of planning services, we use various tools to enable an advanced and fully digitalized way of working. We use QGIS, Smallworld, Megaplan and AutoCAD to capture, analyze and visualize precise geographic data. With the help of TKI NET Design and TKI NET Engineering, we ensure optimal routing and site selection. ​ ​ ​ Thanks to the use of ArcGIS (ESRI), we can also offer an efficient solution for documentation during fiber optic expansion and other network projects.

Insight DLTs Discover DLT's Impact: From Bitcoin's Birth to Diverse Market Applications. DLT EVOLUTION. Since the anonymous release of the first Distributed Ledger Technology (DLT) concept in 2008, epitomized by Bitcoin, DLTs have evolved from a niche playground to transformative tools impacting diverse industries. This article navigates through the basics and advanced functionalities of DLTs. DLT Basics: Blockchain and DAG Blockchain: Originating with Bitcoin, blockchain DLTs create a linear chain of blocks for secure and unchangeable data storage. Each block contains transactions and a hash, validated by miners and nodes. DAG (Directed Acyclic Graph): In DAG DLTs like IOTA's Tangle, transactions occur in parallel, speeding up confirmation. DAG is resource-efficient, suitable for micro devices. Network Components: Nodes, Miners, and Clients Nodes: Servers replicating data ensure DLT integrity and availability. While one node can operate a DLT, networks typically have numerous nodes. Miners: Common in blockchain DLTs, miners validate transactions through cryptographic puzzles. The first miner to validate adds a block to the chain. Clients: Wallets and Data Transactions Wallets: Authenticate users for transactions and data interactions in DLTs, similar to a banking account. Additional Features & Use Cases Smart Contracts: Automated contracts trigger actions based on preset conditions, facilitating responses to real-world data. Digital Twins: Real-world assets get digital twins, unique identifiers connecting digital information. Decentralized identifiers offer a standardized framework. Asset Tokenization: DLTs digitize assets, distributing their value across tokens. For instance, apartment shares are sold as tokens, allowing decentralized investments. Digital Data Marketplaces: Devices sell data on DLT-based platforms. For instance, a 5G antenna provides location data, influencing dynamic pricing for advertisements. Digital Supply Chain Management: DLTs enhance transparency in supply chains, allowing consumers to trace product details through QR codes. E-Voting: DLTs secure electronic voting, providing unique tokens for verifiable and transparent elections. DLTs, from Bitcoin's origin, have grown into versatile tools reshaping industries with applications ranging from finance to supply chain management.
