For those who want to take it to the next level we now have a 3G Cellular Modem breakout! The FONA 3G has better coverage, GSM backwards-compatibility and even sports a built-in GPS module for geolocation & asset tracking. This all-in-one cellular phone module with that lets you add location-tracking, voice, text, SMS and data to your project in a single breakout. This module measure only 1.75"x1.6" but packs a surprising amount of technology into it's little frame. At the heart is a powerfull GSM cellular module (we use the latest SIM808) with integrated GPS. This module can do just about everything Quad-band 850MHz GSM, 900MHz EGSM, 1800MHz DCS, 1900MHz PCs - connect onto any global GSM network with any 2G SIM. This is the European Version - with dual-band UMTS/HSDPA 900/2100MHz WCDMA + HSDPA () Fully-integrated GPS (Qualcomm PM8015 GPS) that can be controlled and query over the same serial port Make and receive voice calls using a headset or an external 8Ohm speaker + electret microphone Send and receive SMS messages Send and receive GPRS data (TCP/IP, HTTP, etc.) AT command interface can be used with 300, 600, 1200, 4800, 9600, 19200, 39400, 57600, 115200, 230K, 461K, 961K, 3.2M, 3.7M and 4.0Mbps Native USB support - plug it into a computer and you'll get serial ports for AT commands, GPS NMEA as well as a modem (note we've only tried out the AT&NMEA ports on Windows) Here's the GPS specifications: 16 acquisition channels GPS L1 C/A code Sensitivity Tracking: -157 dBm Cold starts : -144 dBm Time-To-First-Fix Cold starts: 100s (typ.) Hot starts: 1s (typ.) Accuracy: approx 2.5 meters , while we could get a fix with a passive antenna it took a long time. Please note! We've had a lot of requests for a 3G cell module and we're happy to oblige but this module has many small differences between it and the FONA 800 and 808, so it is not a drop-in replacement! In particular the data functionality is not as easy to use. We are adapting our F
