The HWg SMS-GW3 LTE is a central text SMS gateway for use with compatible environment monitors connected to an Ethernet network. The SMS-GW3 LTE can send SMS alerts and dial pre-set phone numbers specified in the device or the HWg-Trigger software application. The SMS-GW3 LTE requires a SIM card and can be accessed by any of the compatible monitoring devices (see Related Products) on the same Ethernet network at a Box-2-Box level, to allow a single gateway for SMS messages and phone alerts.
LTE is an abbreviation for Long-Term Evolution (LTE) and is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. LTE is the technology behind 4G and is sometimes referred to as 4G LTE. LTE is slower than “true” 4G, but significantly faster than 3G.

The advantage of SMS-GW3 LTE over Email to SMS alerts subscription services is that the device does not require internet connectivity to send the SMS alter or dial a pre-set phone number.
Sending SMS alerts using Poseidon2 Environment Monitors over an Ethernet LAN
As well as a text message, the SMS-GW3 can call the pre-set phone number and let the phone ring for a short time.
HWg-Trigger is an MS Windows application monitors the connected Environment Monitor.
The Nagios NMS monitors the connected devices using SNMP. A plug-in in the Nagios system enables SMS alerts over the SMS-GW3 gateway with configured phone numbers for the text messages.
The SMS-GW3 LTE can be accessed via the Sensdesk.com portal which an be used to monitor and configure alarms using a single web interface. Sensdesk also monitors network connectivity via the internet of connected ARES devices. LAN and GSM sensors (HWg-STE Push and ARES send data to the portal.
SMS alerts from the SensDesk.com online portal
LAN and GSM sensors (HWg-STE Push and Ares 12) send data to the SensDesk.com online portal.
