Sending SMS by Cellular Hardware

Top  Previous  Next

Cellular hardware is the single most reliable and efficient method of delivering SMS. By using cellular hardware, you're removing PageGate's reliance on your internet connection to deliver your messages which means that your internet connection could go down and your messages would still be delivered. It's also incredibly important to note that allowing PageGate to interact with cellular hardware is the only method of configuring a two-way messaging system with SMS.


SMS capable cellular hardware comes in two varieties: cellular modem and cellular router/gateway.


It's also possible to turn an Android phone in to a cellular gateway with NotePage's Android SMS Gateway App. When the smart phone is connected by wifi to the same network as the PageGate server, this app grants PageGate access to the smart phone and allows PageGate to use that cell phone to send and receive text messages. It is important to note that all carrier rules regarding sending text messages for the cell phone plan on the phone apply.


A cellular modem connects to the system PageGate is installed on by USB or RS232 and provides a COM port in the operating system. If PageGate is running in a virtual environment, you can also connect a cellular modem to a COM port virtualizer that provides the COM port to the virtual machine. This grants PageGate access to the cellular modem, which allows it to send and receive text messages just like a cell phone does.


Good examples of cellular modem are:

Multitech's MTC-H5

US Robotics' USR3500

Microhard's IP4NG

Cradlepoint's IBR650


Cellular routers and gateways can be accessed by TCP, so you don't have to connect them to PageGate PC; they just need to be connected to your network and configured appropriately to receive messaging commands.


Good examples of cellular routers/gateways are:

Multitech's MTR-LVW2 and MTR-LAT1

Airlink's GX450 and RV50X
