The Wzzard™ Sensing Platform
The Wzzard intelligent wireless sensor platform makes it quick and easy to connect edge devices and assets and communicate their data to your IoT application for visualization, analytics or integration into business applications. The Wzzard platform connects to a vast range of industry-standard sensors. It uses Wzzard Intelligent Edge Nodes and a wireless SmartMesh IP network to transmit sensor data to the Spectre Network Gateway. The Spectre Network Gateway can connect to the Internet via Ethernet connections or the 3G cellular data network.
The Spectre Network Gateway
The Spectre Network Gateway connects to the SmartMesh IP wireless mesh network and the Wzzard Intelligent Edge nodes through an integrated 802.15.4e radio. The Spectre Network Gateway receives the incoming data stream from edge nodes in MQTT-SN format and converts the information into MQTT protocol for transport to an MQTT broker on your network or on the Internet. The leading IoT applications providers include MQTT brokers in their solutions, and open source MQTT brokers are available for installation on private networks.
The Spectre Network Gateway is built for plug-and-play simplicity with extensive remote management, deployment and customization options. It connects Ethernet equipment and other devices to the Internet or intranet via either 3G cellular or 10/100 wired Ethernet. The standard configuration includes a 10/100 Ethernet port, USB host port, binary input/output (I/O) port and an 802.15.4e radio. It also has an auxiliary port that can be configured for other purposes, like Ethernet or RS-232/485/422.
Secure Connections
To ensure secure communications the Spectre Network Gateway supports the creation of VPN tunnels using IPsec, OpenVPN and L2TP. The web interface provides detailed statistics about gateway activities, signal strength, etc. The gateway supports DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, control by SMS, and many other routing functions. The Spectre Network Gateway also provides diagnostic functions which include automatically monitoring the PPP connection, automatic restart in case of connection losses, and a hardware watchdog that monitors the Spectre Network Gateway status.
