Navigating Wireless Deployment in Automotive Manufacturing

More than a century has passed since Chevrolet first introduced the car radio. The first iteration was bulky and expensive; it wasn't embraced right away. Fast forward to today, however, and the advancements in network technology have taken wireless solutions far beyond this basic form of in-car entertainment.

Wireless now plays a crucial role in automotive manufacturing, as wireless network technology becomes integral to several manufacturing operations, including:

• Wireless data transmission for automated guided vehicles (AGVs) and autonomous mobile robots (AMRs)
  
  
• PDA-driven production operations and mobile data transfer via laptops
  
  
• Wireless data transmission for smart screwdrivers
  
  
• Data communication in emergency management systems (EMSs)

These wireless innovations bring several benefits to automotive manufacturing, including the ability to:

• Support free movement of AGVs and AMRs within the network coverage area, making sure they’re unrestricted by space so they can adapt to changes and obstacles in real-time
  
  
• Relocate equipment and machinery without worrying about restrictions due to cables
  
  
• Reduce operating and maintenance costs by eliminating the need for extensive cabling infrastructure

Overcoming 4 challenges in wireless deployment for automotive manufacturing

But deploying wireless networks in automotive manufacturing environments comes with its own set of challenges. Unlike traditional bus or Industrial Ethernet cables, wireless networks are intangible and invisible, often creating an air of mystery.

While issues with wired networks can typically be identified and resolved through established methods, troubleshooting wireless networks can be daunting for onsite engineers.

Here, we present four of the biggest challenges of wireless deployment in automotive manufacturing, along with our advice to overcome them.

1. The need for extreme reliability

A wireless network deployed in automotive manufacturing must offer high levels of reliability. Any network interruption could cause the production line to stagnate, which leads to downtime, revenue loss and even potential safety issues. As a result, wireless networks must have extremely high levels of stability and reliability and to be able to operate seamlessly for long periods of time in harsh industrial environments.

The solution: Choose reliable network devices.

Choose highly reliable devices and solutions to ensure stable network operations, even in harsh industrial environments. This includes deploying primary and backup wireless networks, implementing PRP (parallel redundancy protocol) networks, and ensuring redundant wireless data transmission.

2. Harsh operating conditions

Automotive manufacturing plants are typically filled with various pieces of large equipment, such as metal devices, robotic arms and conveyor belts. The electromagnetic interference generated by these devices may have a serious impact on wireless network signals. Moreover, environmental factors within the plant, such as temperature and humidity, may also have negative effects on wireless network and device performance.

The solution: Analyze the environment thoroughly.

Use professional wireless scanning software to conduct detailed research and analysis of the plant environment. Properly plan and deploy wireless equipment to minimize the effects of electromagnetic interference and other environmental factors on network performance.

3. Strict safety standards

Automotive manufacturing is a sophisticated industry that relies on sensitive data and trade secrets unique to specific businesses. This makes the security of wireless networks crucial. When deploying wireless networks, it’s necessary to consider requirements such as data encryption, access control and network security and auditing to ensure the security and integrity of data.

The solution: Improve security.

Implement advanced encryption technologies and robust security mechanisms to safeguard wireless data transmission. Additionally, establish a comprehensive network security management system and perform regular security audits and vulnerability assessments.

4. An ever-changing environment

As automotive manufacturing technology and production capacity continue to change and improve, wireless networks must be adaptable to future upgrades. This means that wireless network devices must have excellent scalability and be able to extend coverage and capacity easily.

The solution: Ensure scalability.

Select wireless network devices and solutions with excellent scalability, allowing for flexible adaptation to future production demands and technological upgrades. As production volume increases or processes change, wireless infrastructure can easily expand without major overhauls. This flexibility also supports the integration of new technologies that can enhance automation.
