gps transceiver? gps transmitters are expected on gps satellites only. What are you talking about?
Hi there, I am working on a project. Its a tracker device. I have used a gps and gsm module sim900. and now I Got the location and I can send location to another mobile. But I want to know, how can I send and store the location data to a server? I don't know what to do. Someone please (...)
I am newbie for 8051 microcontroller coding. My need is to getting latitutude and logintude from gps device sending them through (gsm sim900)sms to another mobile. I want to do the coding in c language. I am femiliar with c language but I am newbie to 8051 coding. I searched many ways for finding the code in different links but everywhere (...)
Hi I have a situation of low gsm signal indoor and I need to amplify it I have seen some boosters availble but I wanted to know is it possible to amplify gsm signal using active gsm antennas ? I have some active antennas gor gps and gsm and they have LNA (...)
I have this SIM900 module from sainsmart: When I use it with a MEGA and the library from MarcoMartines here at github: That sketch has this method in it: if (gsm.begin(
Hello, I am building a battery powered application using one cell LIPO battery which is 2500mAh, I am using a system on chip for gsm and BLE, gps module, MCU IC, some sensors. I want to know what's the best design tips to power this application from battery please? is it good to power every module/Chip using a separate buck-boost (...)

Hello. We at are lokking for someone that can help us make a very small run of a custom circuit. The main components will be gsm chip, gps, chip, acclerometer, and a blt 4.0 module. As you might understand we are not pro at this heavey electronic stuff, but we got a full brief and mockups, dimension (...)
I think multi-band. Because of mobile phones (2sim gsm+cdma+gps+bluetooth). maybe. But more recent papers focus on beam steering, something like wifi wich alters beam direction to point in your phone/notebok/pad. To reduce interference, focus power, increase speed.
I heard first time gps module with SPI, Anyways Try going step by step first connect only gps module and then gsm. and display data received on LCD or any terminal for easy debugging.
you need to understand gps signals are not strong as gsm. gps usually was made to work on open sky and not indoor buildings. If you really need to make indoor then consider using active antenna with good gain.
hi friends for my project i am trying to interface gps and gsm in PIC MCU...But what problem now arises means gsm works on 9600Bps and gps works on now i want to use both in my project...but I have tried with PIC16F877A which one UART,,if it is possible to use both in same PIC or else I want (...)
Hi, I'm planning to buy gsm module from AliExpress, as generally available modules are SIM900 or SIM808 as on. I want to know does these modules are supported by most of service providers? like TELUS, Bell etc. Thanks. SIM900 is for gsm and GPRS. SIM808 for gsm+GPRS and gps. both (...)
I'm using PIC18F4550 at 115200 baud rate to get gps information from SIM908. It works fine with commands sent from PC. Also it works fine with commands from MCU. But the problem is, the MCU can not read the gps data sent from SIM908. I checked the MCU, it can read data if I send the data from PC UART. But can not read (...)
You cannot directly use the SIM548 in SIM908 breakout board. There are some modifications on the module, unlike SIM908, SIM548 has separate Power pin for gps , and one extra Serial UART for gps, gps RTC core to help hot Start, etc but if you are only looking for the gsm part, All the functions are exactly (...)
I don't know why do you want to use femtocells for this application. Femtocells ar small base stations, and normally people don't have access to their firmware to get location information. Only the carrier provider have this possibility. For less than $30 you can buy cheap USB tracking devices that use gps and gsm network (...)
As i am using Sierra Wireless gsm gps module HL-6528-G2.8V, in which my module is taking gps frames and after filling it in my packet format ,it is sending this packet format on TCP towards server. I am using TCP connect, Packet send, TCP disconnect in this fashion cycle continuous with interval of 1 minute. Problem is (...)
helo, i have a gsm shield, i want to send the data to php, but it not work.. i use library and using POST example from this but it not work, here the serial output from UNO gsm Shield testing
I am using Atmega 32 Application needs 2 Rx lines. In fact using gsm modem and gps module. It needs communication with both, but I need one at a time only. gsm needs both Rx and Tx, : so giving the serial port to this. One more Rx is needed for gps module. I wish to use 74LS257 (...)
HII!! I am working on project in which i require the person identification from 1-2 meter and that id need to be sent to web-server through gprs(gsm module)with gps location.I am having good knowledge of Atmel AVR(ATMEGA32) series MCU.But i am facing several issues..Please help me. 1) i couldnt found any RFID reader with 1-2 meter (...)
Hi to all, I need A COMPACT CPW-FED UWB ANTENNA WITH gsm, gps, BLUETOOTH and DUAL NOTCH BandS APPLI- CATION antenna design for my thesis. Is there any in these examples? Also i cant take wave port for coaxial in my project. i use hfss v15 in hfss full book v.10 . i donot know how to design slots
generally selecting power solutions for gsm/gps applications will have same requirements. Very good Transient response with little Under and Over voltage overshoots. Check these links.. Micrel good app note and gives possible solut
Please any body help me to design the cpw fed uwb antenna for bluetooth, gps and gsm application with dual notch charecterisics . please give me the steps to design this antenna using hfss
gsm is used only to send SMS ? If yes, then connect 5V TTL Rx pin of gsm to Tx pin of PIC. Connect 5V TTL Tx pin of gps to Rx pin of PIC. If gsm is used to send and receive SMS then use PIC18F46K22. It has two UART.
i tried to connect sim908 gsm gps module to connect with hyperterminal. but the hyperterminal window shows garbage values continously . please help me with the connections and commands to communicate with the module.
Use a I2C LCD + RTC like DS3231 which gives accurate timings. Both are I2C devices and needs only two wires. The eneryy meter will give pulses and you have to read these pulses and do the maths to find out units consumed and cost for the units. Add SIM908 which has both gsm and (...)
is there any virtual USART device like Virtual gsm modem,virtual bluetooth module,virtual gps devices that can be interfaced with proteus ?
which controller and gsm you are using.just read the data from gps and append that data to with your previous done sms programming.for help in code place your code here.
Hello! I'm designing SIM908 based Car gsm module, in which I need 12V to 4V PSU. The device in 99% in sleep mode in minimal current consumption and gps only available on-demand. I've been stuck in this problem for few days, but I don't have the experience to decide surely. I have 2 choices listed in the datasheet: 1. (...)
Hi all, I newbie of arduino and gsm/gps/gprs.. May i ask why we have to register gsm sim908 to network? What is function, and if I do not do so, what will happen? Thanks reply JJ

Hi people, I am trying to make a wiresless gps tracking system using SIM908C and SIM548C as the development board. The issue is, the gsm antenna for SIM908C is given on one side, but when it is placed onto the board the gsm antenna connection for the SIM548C dev kit is on the opposite side. Does it really matter which (...)
Hello, I am looking for antennas for vehicule traking. In fact, the antennes will be stuck with magnetic under the vehicule. For gps antenna (patch), there is no problem, i think, as it has his own ground plane but for gsm900 antenna, there is a problem. Indeed, to preserve a good S11, the reflector should be at lambda/4 and it is equal (...)
Hello, I'm an beginner argentinian programmer, with no idea about designing pcb, but forced to try to design one. Let me explain, my first idea was to purchase the "Small Breakout for SIM908 gsm&gps Module" for learning purposes. But here in Argentina is very complicated to import components. So I purchased the sim908 module, and I want to (...)
