The information flow is often critical and therefore needs to be reliable, available and high speed. To date, the information has been sent using wired networks. Laying cables to each device is both costly and unnecessary. For hazardous environments, Wi-Fi offers many benefits. Wi-Fi is more cost efficient than laying expensive intrinsically safe cables to the places where connectivity is needed. Wi-Fi is more flexible since one access point can serve many different clients and processes at once. Also having Wi-Fi coverage opens up for the use of new technologies such as wireless video collaboration systems for remote problem solving and monitoring.
Benefits from having wireless infrastructure
As described briefly in the introduction, wireless networking opens up possibilities and reduces costs. Wi-Fi is the best way of providing connectivity to the growing number of connected devices. For industrial and hazardous environments, the benefits are even more obvious. These environments are more demanding, meaning that a proven solution that is customized to the application is needed. Installing wireless networks instead of cabled networks cuts cabling cost and enables temporary network connections while maintaining communication speed and security. The cost/benefit of introducing wireless networks is even greater in hazardous and offshore environments, where cables, throughputs, glands and manpower are very expensive. There are several reasons for choosing wireless infrastructure for hazardous area:
- Ease of installation
- Reduced installation costs
- Increase HSE
- Flexible placement of access points
- Short time from installation to commissioning
- Lower footprint and weight compared with wired networks
- No wiring and cable trays leads to increased safety
- Reduce the need for personnel offshore
- Bringing the problem to the expert, not the other way around
- Support multiple locations, operations and processes at once
- Accelerate decision making
- Access to operational data in real time
- Reduce unscheduled downtime on assets
- Coexistence with WirelessHART and other technologies,
- Cisco and Emerson has proven successful coexstence with 802.11 and 802.15.4 technologies
Characteristics of a smart wireless network
A smart wireless network is reliable, secure and easy to deploy. A smart wireless infrastructure allows the user to remotely manage and configure usage and settings. You also want to ensure that the infrastructure supports common standards and enable a wide range of devices to be connected simultaneously and seamlessly. You want the network to be ready for the future, meaning that you want the newest and most up to date technology available. Also, the network should be self-healing and self-optimizing. New installations should embrace the 801.11AC standard since it offers Gigabit Ethernet speeds and excellent flexibility. In addition it cuts down on the number of antennas required reducing the cost compared to the older 802.11n standard.

BARTEC PIXAVI pioneered Wi-Fi for hazardous areas
BARTEC PIXAVI started developing intrinsically safe, IECEx certified wireless infrastructure as far back as in 2002. This gives BARTEC PIXAVI over a decade of experience with wireless networking in hazardous environments. The primary reason for the development of these first Wi-Fi products was to support the use of mobile device for hazardous areas, also developed by BARTEC PIXAVI. The problem was that there was no Ex certified wireless access points available in 2002. BARTEC PIXAVI wanted to make an access point which could easily be retrofitted to existing installations, directly to in the Ex zone. This will decrease installation costs for both retrofitting and new builds. The access points also needed to be customizable and support the latest communication standards. The IECEx and ATEX Zone 1 certification is key for most installations offshore. Increased focus on HSE, ease of installation, and the need to use the access point during an emergency makes this an absolute requirement for most usage scenarios offshore.
BARTEC PIXAVI has been, and will be, a pioneer within wireless infrastructure for hazardous environments. BARTEC PIXAVI was first to introduce dual band access points. Wireless networking infrastructure installations should be ready for tomorrow’s devices. The bandwidth and capability of today’s technology is growing rapidly.
