GSM Phone RS232 Data Acquisition For Your Wire Less Application!If you are working on a system that would work over a cellular network you really do not have much option. You need to possibly work either on a GSM network or on a CDMA one. With the wide spread use of GSM network it is easy for you to implement what you require on a GSM phone RS232 data acquisition system rather than on an equivalent CDMA system. The GSM network is prone to noise insertion in neighboring RF sources. Therefore, you need to take care of this eventuality. But for this issue with the GSM mobile network, there are no other issues faced in terms of signal strength etc., in any of the GSM phones. How would you go about implementing a GSM phone RS232 data acquisition system? It is pretty simple. GSM network is used in the data acquisition only as a transmission medium in lieu of say, a wire based service or a wire less service like a Bluetooth etc., In the case of GSM the distance limitation that the GSM and the WiFi have do not occur. Therefore, this is more or less in line with the high power transmission systems that are used for wire less broad band services. How do you connect your GSM Phone to your computer? One of the easiest ways of doing this is of course through your RS232 serial port. The GSM phone RS232 data acquisition is normally built over the driver for the GSM phone that you have. Most of the companies that make GSM phones also provide you with a CD that can be used to install the GSM phone over your RS232 serial port. This would identify the GSM phone as a modem that works on the serial port. There are of course, systems that also install the GSM phone on the USB port. In this case, we will only look at the phone that works as a serial modem on your RS232 port. The GSM phone RS232 data acquisition is easily done once the phone is installed on your computer. The rest of the operation is as comfortable as any other serial port modem is. Of course, the operational speed of the GSM phone RS232 data acquisition might be quite slow. Normal operating speeds just exceed 9600 bits per second. At such a low baud rate you might not be able to realize a great deal of data transfer. You can install the GSM phone RS232 data acquisition system and have the device also communicate to your phone over a wire less platform. You can find a number of such GSM phones that can also work as a modem on your RS232 serial port. Every one of the phones that can work this way can be used for data acquisition purpose. You need to ensure that the right driver is obtained by you from the manufacturer of the phone. |
