The coaxial cable, with its special radiating characteristics, is rugged and easy to install, and is suitable for use in areas susceptible to explosions (Zone 2), without special approvals. It is connected to SCALANCE W Access Points as an external antenna.

Smart additional functions

iFeatures expand opportunities in industry applications of all kinds

Wireless communication via Industrial Wireless LAN (IWLAN) is already used in countless solutions, e.g. by mobile network participants in Automatic Guided Vehicles (AGV) or in crane applications. Not only the hardware, but also the software of the network components must meet special requirements for use in the industry.

Siemens has developed special iFeatures for use in industrial environments which are enabled by KEY-PLUGs or CLPs inserted into the devices. These smart additional functions can be easily activated as software – also subsequently – on various IWLAN Access Points and Client Modules. These additional functions are suitable for all industries and all kinds of application. The following typical examples of application offer more detailed information.

FAQs

Wi-Fi 6 FAQs

Robust and long-lasting hardware, special approvals, and service

  • The life cycle of industrial Wi-Fi 6 is considerably longer since industrial cycles are longer term than for home or office use regarding investment planning. The devices with the respective technologies are available on the market long-term.  
  • The hardware for industrial Wi-Fi 6 solutions is considerably more robust compared to standard WLAN solutions – and thus optimally suited for demanding environmental conditions (e.g., higher temperature range, high IP protection class with increased protection against water and dust, conformal coating, etc.).
  • Wi-Fi 6 for industry offers special approvals and certifications that are required for the use in an industrial environment. This also applies to special fields of application with, for example, railway approvals for applications in the rail environment or ATEX certifications for potentially explosive areas (ATEX).
  • The industrial Wi-Fi 6 products from Siemens possess international wireless approvals for worldwide use. 
  • Siemens offers both technical and logistical support – internationally. 

Software (see also questions 2 + 3)

  • Wi-Fi 6 for industry makes possible a flexible, low effort scalability of wireless networks in an industrial environment. For example, through the integration into network management systems (such as SINEC NMS), several WLAN components in the network can be centrally commissioned, configured, monitored, and diagnosed.
  • Industrial Wi-Fi also offers expanded optimization options for WLAN parameters, e.g., roaming optimization, channel selection, adjustable channel width, retries, etc.
  • In addition, industrial Wi-Fi 6 solutions from Siemens also cover a comprehensive IT feature set, e.g., VLAN, 802.1x, NAT, etc., which ensures a smooth integration into existing industrial networks.
  • Wi-Fi 6 components from Siemens meet the highest standards, e.g., they are TÜV-certified, and the secure development process is carried out in accordance with the security standard IEC 62443.
  • In contrast to standard Wi-Fi 6 offerings, industrial Wi-Fi 6 solutions from Siemens possess so-called iFeatures – special additional functions for industry, e.g., for redundancy over WLAN.

iFeatures are software-based additional functions that have been specifically developed for the special requirements of industry. Even though Wi-Fi 6 offers numerous improvements over previous WLAN technologies, additional features are needed for industry that go beyond the standard. In focus are, for example:

  • Real-time communication for guided applications using RCoax systems, including Safety Integrated for critical safety applications over WLAN (iPCF)
  • High scalability in terms of the number of participants and the spatial size of the application, e.g., for fleets with automated guided vehicles (AGVs), including Safety Integrated (iPCF-MC)
  • Redundancy and increased availability via wireless WLAN communication (iPRP)

Further detailed information on the iFeatures can be found here.

 

Upon market entry, IEEE 802.11ax (Wi-Fi 6) devices will support iPRP for redundancy over WLAN.

 

IEEE 802.11n devices, on the other hand, also offer the iFeatures iPCF and iPCF-MC. These enable real-time communication, including Safety Integrated concepts, which standard Wi-Fi 6 products without additional industrial functions do not support.


That is why the IEEE 802.11n portfolio (SCALANCE W788/ W774/ W761) still offers better performance for these applications for the time being.

Wi-Fi 6 has the same range as the previous standards since the same frequencies with the same permitted transmission power are used. Both existing plans from the past and the existing accessories, e.g., antennas, can be used. No Wi-Fi 6-specific antenna portfolio is thus required. There are no additional acquisition costs.

 

Note: Spatial Re-Use/ BSS Coloring are not yet to be considered in planning, because these can only have full impact in pure Wi-Fi 6 environments. Within the next few years, we do not see a significant advantage here in 2.4 GHz and 5 GHz.

The portfolio can be used worldwide. You can find the current overview of wireless approvals here.

WLAN with iFeatures and Wi-Fi 6 already enable a wide range of use cases, e.g., connection of mobile participants to series machines, overhead monorails and thruster platforms in the automotive environment, automated guided vehicles (AGVs) and shuttle systems in intralogistics area, train-to-ground communication or passenger service in the transportation industry, and many more.
