The Latest Advantech LoRaWAN Portfolio

LoRaWAN is a media access control protocol for wide area networks that has been designed to allow low-powered devices to communicate with internet-connected applications over long range wireless communications. This is where it gets its name – LoRaWAN – or Low Range Wide Area Network. The LoRaWAN specification defines three device types – Class A, B, and C.

  • Ø Class A devices support bi-directional communication between a gateway and a device, where uplink messages can be sent at any time. After an uplink transmission, the device opens two receive windows at specified times. If the server doesn’t respond in any of these windows, the next uplink transmission will be waited for.
  • Ø Class B devices are an extension of the Class A with an addition of scheduled receive windows for downlink messages from the server. Here, the devices periodically open receive windows by using time-synchronized beacons that are transmitted by the gateway.
  • Ø Class C devices are also extensions of Class A, wherein the receive windows are kept open unless they are transmitting. This allows for low latency communication, but the energy consumed is much more as compared to Class A devices.

Advantech has expanded its range of wireless products with the launch of its WISE-6610 LoRaWAN gateway and Wzzard LRPv2 LoRaWAN node. But, Advantech also understands the increasing demand for intelligent monitoring and warning systems, which make replacing and rewiring existing devices very difficult. This is why it focuses on use of wireless data communication solutions that have a rugged enclosure and flexible software design, and it very well understands that such systems are installed in remote areas and harsh environments.

The Wzzard LRPv2 Node is a LoRaWAN sensing platform that is designed for usage with applications ranging from I/O sensor data management to network protocol conversion. It can be utilized to form a private sensor network that yields immediate dividends by cutting maintenance costs, while increasing overall productivity. Moreover, this node can connect up to four sensors simultaneously, and is ideal for production lines that have sensors, or where there is limited space for additional devices. It is designed to be customizable such that it can accommodate the most sophisticated of monitoring plans. It also offers high flexibility in both hardware and software aspects, thus freeing users from having to deploy an infrastructure-heavy wireless network. This node has two modes, namely the sleep mode for when the node is idle, and the operation mode for data transmission. And, it also comes with an embedded alarm system to notify users when a threshold has been exceeded. All of this helps control the budget by saving power.

The WISE-6610 LoRaWAN Gateway uses the MQTT protocol to connect to a user’s application server or SCADA for data access. It is designed for long range and low bit rate communication among connected objects like battery-powered sensors.

Both these innovations support long range WAN communications, which means there is no need to pay any kind of additional telecommunication costs; thus significantly reducing the costs involved. Moreover, with an IP66 rating, both these devices are protected against dust and water.
