GSM/GPRS module is used to establish communication between a computer and a GSM-GPRS system. Global System for Mobile communication (GSM) is an architecture used for mobile communication in most of the countries. Global Packet Radio Service (GPRS) is an extension of GSM that enables higher data transmission rate. GSM/GPRS module consists of a GSM/GPRS modem assembled together with power supply circuit and communication interfaces (like RS-232, USB, etc) for computer.

The MODEM is the soul of such modules. Wireless MODEMs are the MODEM devices that generate, transmit or decode data from a cellular network, for establishing communication between the cellular network and the computer. These are manufactured for specific cellular network (GSM/UMTS/) or specific cellular data standard (GSM/UMTS/GPRS//HSDPA) or technology (/SIM). Wireless MODEMs like other MODEM devices use serial communication to interface with and need Hayes compatible for communication with the computer (any microprocessor or microcontroller system). Is pretty simple, i hav done SMS based e-votin system, sms remote control, sms based e banking application for diferent firms and individual befor. I do it in 2 ways 1. Conect the Sagem phone(My x7,My V55,V56) modem to the 8051 serial inteface (green to GND,white to p3.0,blue line to p3.1 then send AT command strings to the d modem.

Set the d nodem on text mode first(AT+CMGF=1 & CARRIAGE RETURN(ASCII(13)), AT+CMGL='REC UNREAD' CARRIAGE RETURN(ASCII(13)), any new message will be red from the d phone modem via d controller UART lines 2. In the second method, i do use J2me on any Nokia phone using Messaging APIs(Message connections framework.

But it requires 2 applications runing on 2 phones with the same message port number. Then interface 1 one to the MCU using serialconnections protocol.

Is pretty simple, i hav done dat befor wit JSF and also wit dot net. All u need to do is to implement AT commands using Microsoft Communication control 6.0 in the d dot net framework or u can develop a DLL that listens for an incoming message using this strings(AT + CMGS ='Recipientn phone number' + chr(13),then the message body + chr(26) UNREAD'.

But u need to dedicated an internet computer which will hav a GSM phone modem interfaced to it. Then develop and publish a web service/ a web server side app using ASP.NET or JSF which will take take parameters like( userID, Message body, recipient phone number). The URL of ur web server app will be made available to user, such that users can made HTTP request wit the above parameters. Mscomm1.setSettings('9600,N,8,1'); mscomm1.setDTRenabled(true); mscomm1.setRSEenabled(true); mscomm1.setPortOpen(true); mscomm1.setHandshaking(MscommLib.FLOWCONTROLNONE); the above code wil initialise the d computer on serial communication. For the d Phone Modem to send SMS, it must be in TEXT mode using AT+CMGF=1 + chr(13) mscomm1.setOutput('AT+CMGF=1' + chr(13); // the above wil set d modem on text mode, then on the Request event handler paste //Querry a database to kno if the user is authorised using the userID as criteria mscom1.setOutput('AT+CMGS=' + '/'+ Recipient phone number+/' + chr(13)); mscomm1.setOutput(message body + chr(26)).

Cheers ucontroller, the programing and embeded system guru. Talk to me tru Gtalk wit this ID( add me to ur chat. Am always on line 24/7. Is pretty simple. Solution from ucontroller (the embeded system guru of the continent add me on Gtalk to kno more tins from me usin d ID below or face book ID - Tsokoh Frank) all u need to do is to use an XP system, they are 2 files to be copied - 1. A setup from ur windows NT folder, from Drive C go to program file - Windows NT folder copy Hyperterm and save it in a flash drive, then d second file is dll file from ur system 32 directory, go to Drive C-Windows-System32 folder den copy Hyperterm.dll and save in a flash drive. Den take d flash to ur Windows7 or Vista computer paste the setup in the same windows NT folder, paste the Hyperterm.dll file in the System 32 folder.

Finaly paste the setup also in ur desktop and double click, u wil see ur Hyperterminal runnig sucessfully. Cheers flex ur Hyperterminal.

GSM system was developed as a digital system using time division multiple access (TDMA) technique for communication purpose. A GSM digitizes and reduces the data, then sends it down through a channel with two different streams of client data, each in its own particular time slot. The digital system has an ability to carry 64 kbps to 120 Mbps of data rates. GSM Modem There are various cell sizes in a GSM system such as macro, micro, pico and umbrella cells.

Each cell varies as per the implementation domain. There are five different cell sizes in a GSM network macro, micro, pico and umbrella cells. The coverage area of each cell varies according to the implementation environment. Time Division Multiple Access TDMA technique relies on assigning different time slots to each user on the same frequency. It can easily adapt to data transmission and voice communication and can carry 64kbps to 120Mbps of data rate.

GSM Architecture A GSM network consists of the following components:. A Mobile Station: It is the mobile phone which consists of the transceiver, the display and the processor and is controlled by a SIM card operating over the network. Base Station Subsystem: It acts as an interface between the mobile station and the network subsystem.

It consists of the Base Transceiver Station which contains the radio transceivers and handles the protocols for communication with mobiles. It also consists of the Base Station Controller which controls the Base Transceiver station and acts as a interface between the mobile station and mobile switching centre.

Network Subsystem: It provides the basic network connection to the mobile stations. The basic part of the Network Subsystem is the Mobile Service Switching Centre which provides access to different networks like ISDN, PSTN etc. It also consists of the Home Location Register and the Visitor Location Register which provides the call routing and roaming capabilities of GSM.

It also contains the Equipment Identity Register which maintains an account of all the mobile equipments wherein each mobile is identified by its own IMEI number. IMEI stands for International Mobile Equipment Identity. Features of GSM Module:.

Improved spectrum efficiency. International roaming. Compatibility with integrated services digital network (ISDN). Support for new services. SIM phonebook management.

Fixed dialing number (FDN). Real time clock with alarm management. High-quality speech. Uses encryption to make phone calls more secure. Short message service (SMS) The security strategies standardized for the GSM system make it the most secure telecommunications standard currently accessible. Although the confidentiality of a call and secrecy of the GSM subscriber is just ensured on the radio channel, this is a major step in achieving end-to- end security. GSM Modem A GSM modem is a device which can be either a mobile phone or a modem device which can be used to make a computer or any other processor communicate over a network.

A GSM modem requires a SIM card to be operated and operates over a network range subscribed by the network operator. More than or more than. It can be connected to a computer through serial, USB or Bluetooth connection.

A GSM modem can also be a standard GSM mobile phone with the appropriate cable and software driver to connect to a serial port or USB port on your computer. GSM modem is usually preferable to a GSM mobile phone. The GSM modem has wide range of applications in transaction terminals, supply chain management, security applications, weather stations and GPRS mode remote data logging. Working of GSM Module: From the below circuit, a GSM modem duly interfaced to the MC through the level shifter IC Max232.

The SIM card mounted GSM modem upon receiving digit command by SMS from any cell phone send that data to the MC through serial communication. While the program is executed, the GSM modem receives command ‘STOP’ to develop an output at the MC, the contact point of which are used to disable the ignition switch. The command so sent by the user is based on an intimation received by him through the GSM modem ‘ALERT’ a programmed message only if the input is driven low. The complete operation is displayed over 16×2 LCD display. GMS Modem Circuit Intelligent GSM Device for Automation and Security In these days, the GSM mobile terminal has become one of the items that are constantly with us. Just like our wallet/purse, keys or watch, the GSM mobile terminal provides us a communication channel that enables us to communicate with the world. The requirement for a person to be reachable or to call anyone at any time is very appealing.

In this project, as the name says project is based on GSM network technology for transmission of SMS from sender to receiver. SMS sending and receiving is used for ubiquitous access of appliances and allowing breach control at home. The system proposes two sub-systems. Appliance control subsystem enables the user to control home appliances remotely and the security alert subsystem gives the automatic security monitoring. The system is capable enough to instruct user via SMS from a specific cell number to change the condition of the home appliance according to the user’s needs and requirements. The second aspect is that of security alert which is achieved in a way that on the detection of intrusion, the system allows automatic generation of SMS thus alerting the user against security risk. Circuit Representation of Intelligent GSM Device for Automation and Security: Intelligent-GSM-Device-for-Automation-and-security GSM will allow communication anywhere, anytime, and with anyone.

The functional architecture of GSM employing intelligent networking principles, and its ideology, which provides the development of GSM is the first step towards a true personal communication system that enough standardization to ensure compatibility. Photo Credit. GMS Modem.
