What should you compare when reviewing Ex wireless installation and maintenance requirements? 

When comparing Ex wireless solutions, product suitability, certification and cost will usually be the primary considerations. Installation and maintenance requirements should also form part of that assessment, as they can influence how straightforward the system is to deploy and support over its lifetime. 

Different suppliers offer varying levels of: 

• Installation guidance: Clear documentation to support correct installation and commissioning.  

• Hazardous area and wireless expertise: Specialist knowledge of Ex compliance and wireless performance.  

• System flexibility: Ability to adapt the solution to different equipment and site requirements.  

• Maintenance accessibility: Design that makes inspection and component access straightforward for the site’s own maintenance teams. 

These factors can affect how easily a system is installed, serviced, adapted, refurbished, or upgraded over time; ultimately influencing the total cost of ownership. 

Once the required specification and application fit have been established, consider how the system will be installed and maintained in practice. The use case will influence factors such as coverage and bandwidth to antenna design, access for inspection, and future maintenance. 

Ex wireless systems can support many hazardous area use cases, including: 

• Mobile worker connectivity: Access to site systems and digital tools. 

• Asset tracking: Locating people, tools, or equipment. 

• Telemetry: Sending field data to central systems. 

• Remote monitoring: Viewing equipment status and alarms. 

• Voice communications: Worker, control room, and team communications. 

• Video: Visual monitoring for safety or operations. 

• Control system data: Connecting devices to operational networks. 

• Connected safety applications: Improving safety visibility and response. 

The intended use case will influence the practical requirements of the system, including: 

• Coverage area: Where the wireless signal must reach. 

• Bandwidth: The volume of data being transmitted. 

• Latency: How quickly data needs to transfer. 

• Availability: How reliably the connection must operate. 

• Antenna design: Antenna type, placement, and orientation. 

• Power and data infrastructure: How the system connects and integrates. 

• Maintenance access: How easily teams can inspect components.  

• System flexibility: How easily the solution can be adapted as equipment or site requirements change. 

Once the use case is clear, you can compare installation and maintenance instructions more meaningfully for the solutions you are considering. For example, an asset tracking deployment may require a different number and placement of access points than a system supporting live video because its coverage, capacity, bandwidth, and latency requirements are different. This can affect antenna positioning, cable routes, power requirements, installation time, inspection routines, and ongoing maintenance. 

These considerations can vary significantly between suppliers. A lower-cost box-build solution may meet the initial specification, but limited wireless expertise, maintenance access, or upgrade options can increase effort and cost later. Purpose-designed systems that support refurbishment, component replacement, and future upgrades can therefore offer greater flexibility throughout the installation’s lifecycle. 

For example, Extronics (BARTEC’s connectivity & IoT brand) designs hazardous area wireless solutions as complete certified systems, helping simplify installation by considering antennas, cable entries, power, and RF accessories together rather than as separate components. This makes it easier to compare lifecycle requirements alongside wireless performance. 

What maintenance instructions can tell you 

Maintenance requirements for hazardous area wireless systems are shaped by both applicable regulations and the manufacturer’s instructions. Regulatory requirements determine many of the inspection and maintenance activities that must be carried out, while manufacturer documentation explains how those requirements apply to the specific equipment. 

When comparing solutions, consider both regulatory requirements and the manufacturer-specific information provided, including: 

• Inspection frequency: What inspection intervals apply, and does the manufacturer provide clear guidance to support them? 

• Inspection tasks: Which parts of the system need to be checked, such as the enclosure, seals, glands, antennas, cables, labels, or fixings? 

• Access requirements: How easily can the site’s own maintenance teams access the relevant components for inspection or maintenance? 

• Cleaning requirements: Are there specific instructions for managing dust, contamination, corrosion, or washdown conditions? 

• Replacement rules: Which components can be replaced, and what conditions or certification requirements apply? 

• Upgrade options: Can wireless hardware, antennas, or accessories be updated without replacing the complete system? 

• Documentation and maintenance support: Are clear manuals, maintenance information, and digital resources available to help teams carry out the required work correctly? 

The key difference is not necessarily how often equipment must be inspected, as this may be determined by the applicable hazardous area regulations and site procedures. Instead, compare how straightforward the equipment makes those activities and how clearly the manufacturer supports them. 

For example, the modular chassis design used in our iWAP allows key system components to be integrated within a purpose-designed hazardous area wireless platform. This can make inspection, component access, refurbishment, and future upgrades more straightforward than treating the wireless equipment and certified enclosure as unrelated parts of the installation.

Site conditions that change the comparison  

Installation and maintenance instructions should also be compared against the real site environment. Hazardous area wireless systems may need to operate in conditions such as: 

• Corrosive atmospheres 

• Washdown processes 

• Offshore or marine exposure 

• High levels of vibration 

• Temperature extremes 

• Outdoor weather exposure 

• Dust build-up or contamination 

• Restricted access for maintenance 

These conditions can change what “easy to install” or “easy to maintain” means in practice. For example, a system installed outdoors or offshore may need closer attention to: 

• Enclosure material: Whether the housing is suitable for the environment, such as stainless steel for corrosive areas. 

• Ingress protection: How well the system is protected against dust, water, and outdoor exposure. 

• Antenna mounting: How antennas are positioned, secured, and protected while maintaining wireless performance. 

• Corrosion resistance: How well components withstand chemicals, salt spray, moisture, or harsh atmospheres. 

• Cable routing: How power, data, and RF cables are run, protected, and terminated safely. 

• Inspection access: How easily maintenance teams can reach the system for checks, servicing, or replacement. 

For many hazardous area projects, selecting equipment designed specifically for demanding industrial environments can reduce maintenance effort over time. Extronics offers solutions engineered for harsh environments, including offshore, chemical processing, pharmaceutical, and manufacturing applications, where durability and long-term serviceability are key considerations.

How Extronics supports informed comparison

Extronics designs its hazardous area wireless enclosure solutions with installers, maintenance teams and future expansion in mind. This means considering not only wireless performance, but also how the complete certified system will be installed, inspected, maintained and adapted throughout its operational life. 

That includes the:  

• Application  

• Hazardous area classification  

• Certified system design  

• Antennas  

• RF accessories   

• Cable entries  

• Power and data arrangements  

• Maintenance access, and upgrade path.  

By reviewing these factors early, customers can select an Ex wireless solution that supports the required application while remaining safe, compliant, accessible, and maintainable throughout its operating life.
