URLLC (Ultra-Reliable Low-Latency Communication) is transforming industrial automation by providing faster, more dependable wireless communication. This technology delivers under 1ms latency and 99.99999% reliability, enabling advanced automation, real-time control, and efficient workflows. Here’s what makes URLLC a game-changer:
URLLC’s performance empowers industries to improve efficiency, safety, and scalability, making it a core component of next-gen manufacturing systems.
5 Key Benefits of URLLC for Industrial Automation: Performance Metrics and Impact
URLLC (Ultra-Reliable Low-Latency Communication) pushes latency below 1 millisecond through innovations in data transmission. One key advancement is mini-slot transmission, which reduces the time taken to send data by using just 2 symbols instead of the usual 14, significantly cutting waiting times for control signals. Another breakthrough is grant-free uplink access, allowing devices to transmit immediately without the delays of traditional 4G handshakes, which can save up to 11 milliseconds.
Edge computing plays a vital role by moving data processing directly to the factory floor, reducing round-trip times to a minimum. Meanwhile, network slicing creates dedicated virtual lanes for URLLC traffic, keeping it separate from high-bandwidth applications like video streaming. This ensures that critical data flows smoothly, unaffected by other network demands – meeting the real-time requirements of industrial operations.
These advancements are crucial for precision control in next-gen processes. For example, high-precision robotics rely on millisecond-level synchronisation to execute algorithms flawlessly, avoiding errors that could damage sensitive components. Likewise, Automated Guided Vehicles (AGVs) demand latency of approximately 5 milliseconds and 99.99% reliability for safe and efficient navigation, both of which URLLC easily delivers.
To achieve these low latencies, industrial operators must deploy edge nodes on-site to avoid delays caused by backhaul processing. Using synchronisation protocols such as IEEE 1588 PTP or GPS ensures sub-millisecond timing accuracy. This is critical because even a minor timing error – like 1 microsecond – can increase latency by as much as 15%.
This ultra-low latency is foundational to the efficiency, reliability, and advanced automation capabilities explored further in the following sections.
URLLC ensures an astonishing reliability rate of 99.99999%, which translates to just one failure per million packets. This level of consistency is crucial for preventing communication issues that could lead to robotic assembly lines or CNC machines halting unexpectedly. For example, in car parts assembly, even a slight signal interruption can disrupt production and potentially damage components. Such reliability is essential for keeping operations running smoothly and without interruptions.
This technology also excels in environments where standard wireless signals often struggle. Factories with induction motors or high-frequency equipment, which typically interfere with wireless connectivity, benefit greatly from URLLC’s stable performance. By leveraging network slicing, critical data is prioritised, ensuring that control commands reach machinery without delays or interference. This eliminates the brief stoppages that are common with traditional networks.
"The high reliability ensures that data packets are delivered with minimal failure rates… [it] is critical for applications in automation, manufacturing, and transportation for continuous and reliable operation of industrial systems."
– Dan Omalley, Expert in 5G, Nybsys
Reliable connectivity doesn’t just prevent production halts – it also supports proactive maintenance. By maintaining a continuous flow of data from sensors to AI-driven analytics platforms, operators can monitor equipment in real time. This allows them to detect early signs of wear and schedule maintenance before a breakdown occurs, rather than scrambling to fix unexpected failures. In high-stakes safety scenarios, such as when a human enters a hazardous area, proximity sensors can instantly shut down machinery, avoiding accidents and the downtime they would cause.
To ensure uninterrupted operations, additional measures complement URLLC’s low-latency capabilities. Deploying edge computing alongside URLLC guarantees localised processing, which maintains connectivity even during network disruptions. Dual connectivity – combining 5G with LTE as a backup – adds another layer of reliability, keeping operations running even if one network experiences an issue. Partnering with providers like Firecell for private 5G networks further enhances stability, offering interference-free connections seamlessly integrated into existing enterprise systems.
Thanks to URLLC’s low latency and dependable performance, wireless systems are transforming operational workflows. Unlike wired setups, URLLC offers unparalleled flexibility, allowing daily production adjustments to maximise output. As Ericsson aptly put it, "Cutting the cables is the real game changer in enabling Industry 4.0." This wireless adaptability is driving noticeable productivity improvements in modern manufacturing environments.
Take, for instance, an electric vehicle manufacturer that, in November 2023, transitioned from Ethernet connectivity to a 5G URLLC system developed by QCT and Intel. This shift eliminated the cable-related downtime that had been causing 60 hours of delays each month, boosting production by an impressive 3,600 vehicles monthly. Guang Yang, Senior Principal Analyst at QCT, highlighted the impact:
"The 5G system with URLLC capability can eliminate [downtime] loss whilst providing the same SLA, enabling an additional production of around 3,600 vehicles per month."
The sub-1ms latency of URLLC plays a key role here, ensuring precise synchronisation of robotic arms and machinery. This precision allows machines to operate at higher speeds without risking errors or misalignments. Real-time sensors, combined with advanced learning algorithms, continually optimise production processes, maintaining stability and reducing inefficiencies. For example, high-precision indoor tracking – accurate to within 1 metre – ensures tools activate only in designated zones and that assembly sequences are completed correctly. This eliminates costly rework and reduces the need for manual quality checks.
Safety is another area where URLLC excels. During a January 2020 test by Audi and Ericsson at Ericsson’s factory lab in Kista, a laser curtain connected via 5G instantly halted robots when needed. The robots, which were assembling steering wheel airbags, relied on wireless connectivity rather than cables, allowing their cells to be moved daily to optimise production layouts.

URLLC serves as the foundation for cutting-edge industrial systems that depend on instant and reliable communication. Technologies like autonomous guided vehicles (AGVs), collaborative robots, and augmented reality systems thrive on network performance that older wireless solutions simply cannot match. These systems demand not just connectivity but also sub-millisecond latency and near-flawless reliability.
Thanks to URLLC’s low-latency and high-reliability features, advanced automation technologies are now more viable than ever. For instance, AGVs require latency of about 5 ms, while motion control systems demand an even tighter 1 ms latency, along with the precision and dependability needed for millimetre-level accuracy. These stringent benchmarks are essential for ensuring safe and efficient operations. Augmented reality applications take this a step further by overlaying real-time assembly instructions or maintenance guidance directly into workers’ fields of vision. This opens up new opportunities for training and handling complex assembly tasks – scenarios that traditional wireless networks could not support.

URLLC isn’t just about speed and reliability – it also shines in environments packed with devices. Think of modern factories, where hundreds of devices, from sensors to autonomous guided vehicles (AGVs) and safety systems, are all working simultaneously. URLLC handles this complexity through network slicing. This technique creates dedicated virtual pathways within the same physical network, separating mission-critical signals from large data streams. The result? Control commands are delivered on time, no matter how busy the network gets.
Another standout feature is grant-free uplink access. By reserving capacity in advance, URLLC reduces delays in crowded networks, ensuring that time-critical commands get through without a hitch. If resources in other slices are needed, URLLC steps in to reallocate them for these urgent tasks.
To further guarantee reliability, URLLC uses redundant transmission. Essentially, it duplicates data packets and sends them through separate paths. This ensures that even in the face of congestion or system failures, the information arrives when it’s needed. With private 5G antennas powered by URLLC, a single base station can support hundreds of devices while maintaining strict performance standards.
"URLLC facilitates highly efficient scheduling of data transfers, shorter transmissions through larger subcarriers, and overlapping transmission scheduling."
