# 6G Enabled Industrial Internet of Everything: Towards a Theoretical Framework
## 6 GIIoE Architectural Framework
### 6 GIIoE Priority Areas, Applications, and Challenges  
#### Priority Areas  
Based on the exhaustive literature review, survey (mentioned in the Section 3.2) [33] and white paper published by Siemens, Huawei, Cisco [3,8,9], findings divulged that IoT/IoE affects various industries, and the topmost priority areas are customer experience, asset management and financial decision making.  
First on the list of priority area is to enhance customer experience. The following ways 6G enabled IIoE system can enhance the customer experience:  
* Perpetual monitoring of customer experience with company offerings.
* Personalizing the situation for each customer.
* Updating products and services based on learning over time with customer interactions.
* Continuous innovation product access and purchasing experience.  
The second and third priority areas are asset management and financial decision making, respectively. The 6G enabled IIoE system can play a significant role in financial decision making by facilitating asset tracking and managing real time visibility. Top priority areas may differ based on industrial applications. Customer experience and financial decisions (asset management tracking) facilitate a sound foundation of functional areas for practitioners and academic researchers to appraise.  
Furthermore, the following specific priority areas of 6G and IIoE needed attention:  
* 6G should entrust MTRLLC for mobility management at high frequency mmWave bands and THz beyond.
* 6G requires a move towards radio centric system design and end-to-end co-design 3 CLS [25] (p. 3) (Convergence of Communications, Computing, Control, Localization, and Sensing) driven by artificial intelligence (AI).
* 6G vision should be driven by a diverse portfolio of applications, technologies, and techniques.
* 6G high density tiny cell base station paradigm should embark upon a new era of smart surfaces communicating with human-embedded implants.
* Performance target analysis and optimization of 6G should operate in 3D space.
* IIoE: customer focused perspectives--the term \"IIoE\" is about the ways IoE can be used for industrial applications. IIoE focuses on improving connectivity between devices, time/cost savings and achieving efficiency optimization for industries. IIoE is amid a fundamental transformation with connected devices growing, up to 75 billion by 2025 [45], more and more enterprises are entering the industrial IoE arena. In the past, IoE interconnectivity was exclusively for enterprises that had the resources to build an IoE system. Nowadays, companies opt for a pre-built and full-stack managed IoE service that can offer the necessary hardware, software, and edge (cloud) infrastructure to handle billions of concurrent device or sensors, or machine connections to edge (cloud) network infrastructure such as 6G.
* IIoE: predictive maintenance and analytics (PMA)--Industries are using IoE-enabled systems to send out notifications to maintenance crews to predict when equipment is about to fail. This reduces the amount of maintenance time and allows maintenance crews to spend time to focus on other tasks. IoE-enabled systems collect massive data on how often these notification failures are sent out. Industries can use and communicate this massive data via 6G to create maintenance timelines and save significant cost and time, allowing teams to service equipment before it even fails. Predictive maintenance and analytics (PMA) [46] are becoming one of the most important use cases for industrial analytics.
