The demand for personalised products from consumers is a growing trend and as such requires a paradigm shift from mass-production to mass-customization. The realisation of Industry 4.0 provides opportunities for the industrial sector to create modular and flexible production lines that can be rapidly adapted to cater for on-demand manufacturing needs. This modular approach demands a flexible communications infrastructure that can provide reliable connectivity across these manufacturing cells. The use of static wired networks limits adaptability and as such wireless communications are receiving far more attention. Wireless offers the advantages of low cost, seamless deployment, higher flexibility and scalability. However, before wireless communications can be leveraged they need to meet the tight constraints of industrial automation. As per Ultra Reliable Low Latency Communication (URLLC) for industrial communications, sub-millisecond-latency and 1 packet loss in 100K packets is essential. Industrial channel specific optimized approach using Polar codes is proposed as a solution.
