Industrial Wi-Fi for explosive environments with the ability to build MESH networks

Industrial Wi-Fi is necessary for building a reliable and high-speed wireless communication system in various production and industrial environments.

Kyland’s wireless Wi-Fi devices of KyAir series can be used for such tasks as:

• Quick access to data and applications
• Automation of processes using wireless devices
• The ability to quickly move equipment, such as AGV carts, without the need to organize a cable connection
• Implementation of real-time monitoring systems to track the status of equipment and processes
• Connection of IoT devices for data collection and analysis

As a result, industrial Wi-Fi is becoming an important tool for modernizing and optimizing production processes, increasing efficiency and reducing operating costs.

Moreover, wireless Wi-Fi devices of the KyAir series include KyAir600F and KyAir800F models which can be used in explosive environments in accordance with the explosion protection class

_Exd IIC T6 Gb:

• _ Explosion protection level symbol - degree of protection of an electrical device from explosion (0 or no designation)
  An explosive gas mixture is present continuously or for long periods of time. Particularly explosion-proof electrical equipment, which differs from explosion-proof equipment by the presence of additional explosion protection means
• Conformity symbol - conformity of the mounted device to the international standard (Ex)
  Products incorporating one or more types of explosion protection for potentially explosive gas environments
• Explosion protection type symbol - what type of protection does the equipment belong to (d)
  Explosion-proof enclosure
• Subgroup symbol - mixture category (IIC)
  For indoor and outdoor installation (except mines). Industrial gases and vapors (BEMZ, mm up to 0.5)
• T6. Temperature class symbol - Autoignition temperatures of explosive gases and mixtures (temperature class)
  85-100°С
• Gb
  An area in which there is a possibility of the presence of an explosive gas mixture under normal operating conditions.

Also one of the significant advantages of Wi-Fi devices of the KyAir series is that in addition to the fact that most models support standard AP/Client/bridge modes, the KyAir800 series in turn supports IEEE 802.11k/v/r standards for seamless roaming using instant switching technology. Thanks to the support of these standards by the KyAir800 it is possible to build a MESH network at an industrial facility.

The MESH network provides seamless, high-speed switching between access points as the client moves between them and includes the following principle:

The client detects a decrease in the signal level from access point n1. It then analyzes the network to find another access point with a stronger signal. The client then disconnects from access point n1, goes through the authentication process and connects to access point n2, and so on as the client moves to subsequent access points n3-n[…].

Without MESH technology, the process would be different: the client would first disconnect from access point n1 with a low signal level and only then start looking for a new access point n2 with a more stable signal level. This could take up to several seconds to switch, which is often critical for industrial networks.

Up to 6 KyAir800 devices can be used in one MESH network в режиме AP (access point), with the ability to connect up to 254 client devices.

The table below shows the full range of wireless Wi-Fi devices of the KyAir series and their key features:

In addition, the Kyland Wi-Fi device lineup includes an industrial wireless controller of the KyAir3006 series, which makes it possible to centrally manage a wireless network built of KyAir600 and KyAir800 devices. This series of controllers, depending on the configuration, supports from 64 to 2048 access points in AP (access point) mode.
