LoRaWAN gateway with GSM LTE

UG67 uses a concentrator based on Semtech SX1302 and has 8 LoRaWAN® channels.

The current manufacturer specification indicates support for both half-duplex as well as full-duplex and LoRaWAN® Class A, Class B and Class C end devices.

Receiver sensitivity reaches −140 dBm at 292 bps, while the maximum transmit power is 27 dBm.

Version 868M is intended, among other applications, for operation according to the European EU868function.

frequency plan. The UG67 hardware platform also supports the CN470, IN865, RU864, US915, AU915, KR920 and AS923-1/2/3/4 regional plans.

For installations in Poland, the appropriate frequency plan is EU868.

The UG67 has 2 external N-Female 50 Ω antenna connectors for the LoRaWAN® interface.

This allows the antennas and installation method to be adapted to the required coverage area, terrain conditions and gateway mounting height.

Milesight offers, among others, a compatible GA01 fibreglass antenna 130 cm long with 8 dBi gain for the 860–868 MHz range.

According to the manufacturer, one UG67 gateway can support approximately 2000 LoRaWAN® Class A/B/C devices with an uplink interval of approximately 10 minutes.

Actual network capacity depends on the number of transmissions, radio parameters, packet size, downlink communication frequency and propagation conditions.

The UG67 has built-in LoRaWAN® Network Server, allowing it to provide local network support without the need for a separate LNS.

The built-in codec library enables decoding of Milesight devices as well as definition of custom codecs for other devices.

Data integration can be performed via MQTT(S), HTTP(S), BACnet/IP, BACnet/SC, Modbus TCP and Modbus RTU over TCPfunction.

Function Gateway Fleet enables several Milesight gateways to be combined into one logical structure.

One gateway can act as the controller with a built-in Network Server, while the remaining devices operate as agent gateways extending network coverage.

The solution simplifies construction of larger installations and reduces the need to configure a separate Network Server independently for each access point.

Noise Analyzer enables scanning interference levels on individual frequencies and simplifies selection of appropriate radio channels.

Packet Filter allows packet whitelists and blacklists to be created, while Data Retransmission enables stored data to be resent after the network connection is restored.

The built-in Network Server also supports Multicast and FUOTA for compatible end devices.

Variant UG67-L08GL-868M is equipped with 4G LTE cellular communication and is the current successor to older UG67 versions with different cellular modules.

The cellular interface uses an internal antenna, so the installation does not require a separate external LTE antenna.

The gateway has one card slot Mini SIM 2FFfunction.

The UG67 has 1 RJ45 WAN 10/100/1000Base-T portfunction.

The port supports automatic speed detection, Auto MDI/MDIX and Full/Half Duplex mode.

The Ethernet interface can also power the device as IEEE 802.3af PoE PD, allowing communication and power to be delivered over a single cable.

The UG67 has Wi-Fi IEEE 802.11b/g/n 2,4 GHz with an internal antenna.

The interface can operate as both Access Point as well as Client, allowing it to be used for configuration and as an additional network communication method.

Supported security includes WPA/WPA2-PSK, and WPA/WPA2 Enterprise in client mode.

The UG67 supports WAN Failover and Failbackfunction.

This allows Ethernet, Wi-Fi and the cellular network to be used as alternative access paths to the higher-level system.

If the primary link is lost, the gateway can switch communication to an available backup connection.

The UG67 has a built-in GNSS receiver supporting GPS, GLONASS, QZSS and SBASfunction.

The GNSS antenna is integrated inside the enclosure.

The manufacturer specifies positioning accuracy of approximately 2,5 m CEP in open spacefunction.

UG67 uses 64-bit, quad-core ARM Cortex-A53 1,5 GHz processorfunction.

The device has 512 MB DDR4 RAM and 8 GB eMMCfunction.

Support for Node-RED and Python SDK enables custom logic, local data processing and implementation of additional functions directly on the gateway.

The UG67 supports multiple VPN technologies, including OpenVPN, IPsec, PPTP, L2TP, GRE, DMVPN and WireGuardfunction.

The built-in firewall offers, among others, Access Control, DMZ, Port Mapping/DNAT, MAC Binding and IP address and domain filtering.

Multi-level user permissions and encrypted administration methods via HTTPS and SSH are also available.

Device configuration can be performed via Web, CLI via SSH/Telnet, SMS, SNMP, HTTP API and MQTT APIfunction.

For remote management, updates and management of larger numbers of gateways, the following are available: Milesight Development Platform and DeviceHubfunction.

Diagnostic tools include Ping, Traceroute, Tcpdump, QXDM and Log Server.

The UG67 has a built-in supercapacitor providing approximately 1 minute of backup powerfunction.

This energy can be used to send a power-loss notification before the device shuts down.

This is particularly useful in remote installations where loss of power to the gateway itself should be recorded by the higher-level system.

The UG67 can be powered via IEEE 802.3af PoE through the Ethernet port.

Alternatively, the device supports 6–12 V DC through an M12 A-Coded connectorfunction.

Typical power consumption is approximately 3,6 W, with a maximum of 4,8 W.

The UG67 has an enclosure made of UL94 V0 polycarbonate and ADC-12 aluminiumfunction.

The IP67 enables the device to be used in outdoor installations exposed to dust and precipitation.

Gateway dimensions are 240 × 164 × 90,9 mm, weight approximately 1463 g, and the design enables wall or pole mounting.

The UG67 operating temperature range is −40…+70°Cfunction.

The manufacturer notes that cellular communication performance may be limited at temperatures above 60°C.
