Reserve Your Seat TodayGlobal System for Mobile Communication (GSM) is a standard used in cellular communication networks. Amongst all cell technologies in use nowadays, GSM is one of the most widespread.
To begin, it's essential to distinguish between GSM modems, modules, and mobiles:
GSM Modems: These are external devices designed to connect to equipment, providing wireless communication capabilities. They function independently and are often used in various industrial applications.
GSM Modules: Unlike modems, these are embedded components integrated within equipment. They serve as a foundational piece of hardware, allowing devices to communicate over mobile networks.
GSM Mobiles: These devices are complete systems with embedded processors. They provide an interface between the user and the mobile network, offering a full range of functionalities beyond simple data transmission.
Each of these components serves a distinct role within the mobile communication landscape, offering varying degrees of integration and functionality.
GSM modules offer connectivity along with wireless data communication transfer. These devices are light and easy to use as well as having a surprisingly low power consumption for the amount of work they can do. They can be used for tracking communication projects, linking together a remote site monitoring system with your LAN, as well as many other applications.
A GSM module accepts a SIM card, and operates over a subscription to a mobile operator, just like a cell phone or pager.
Key Components of a GSM Module:
To understand its components, think of a GSM module as a chip or circuit designed to enable communication between a mobile device or computing machine and a GSM system. At its core, it includes three crucial components:
Power Supply Circuit: Essential for powering the module.
Communication Interfaces: These include RS-232, USB 2.0, and others, allowing for connectivity with computers.
A GSM modem can either be a dedicated device with options for serial, USB, or Bluetooth connections, or it can function as a mobile phone offering GSM modem-like capabilities to modules. This adaptability makes them versatile for various applications.
Cellular connections can be a quick and efficient way to get started with SMS notifications in network monitoring solutions because a special subscription to a separate service provider is not required. In most parts of the world, GSM modules are a cost-effective solution for sending and receiving alarm notifications since the utilization of existing networks instead of having to expand your infrastructure to include hardware that allows direct connections with your remote sites.
The NetGuardian 216 G3 optional GPRS/GSM or CDMA wireless modem, allowing you to report alarms from your remote sites without LAN or dialup connections via SMS notifications over a cellular band. This allows you to take your alarm monitoring outside of your network and have the flexibility to report to a central location such as a T/Mon Master Station.
This new NetGuardian 216 G3 can also quadruple the analog inputs of its predecessor. Now that you can choose up to 8 analogs, you can monitor temperature, humidity, battery voltages, fuel levels, and other critical values from a single compact RTU.
The other major feature of the G3 that's superior to the G2 is standard web browser access, which offers intuitive monitoring for technicians without extensive training. This is the client-favorite web interface that's become a standard part of modern DPS remotes. Your techs simply type the IP address of the NetGuardian into their web browser and log in. They'll have access to all current alarms, real-time analog values, and a handy editing interface for adjusting RTU settings.
