Allows you to create data connections on the GSM network through a standard USB interface.
The cellular modems, particularly USB-stick ones, are now at very affordable prices, however they’re limited: they are explicitly designed for Internet connections, so you cannot use it as a normal modem and so implement, for example, a point to point data communications with them. The GSM modems …

Some post ago we presented a PCB to mount the SIM900 module. The projects is used in our GSM remote control and the Arduino GSM Shield.
The dimensions aren’t big (1.75×1.95 inches) but in some cases they are too important for a projects, so….

..we have developed a small PCB GSM module to build device like localizators (coming soon… ), bugs or other …

This GSM Mobile is used for our Remote Control (for example Gate Control, Temperature Control….). We use the word ‘module’ because, unlike what we did in our remote control projects, this time around the mobile phone is not mounted on a printed board, but rather on a small auxiliary board which is then inserted in a connector specifically created on the …

This module produced by Quectel, too, is GSM/GPRS (GSM Phase 2/2+) compatible and is a Quad-band type; the radio section works at a frequency of GSM 850 MHz, GSM 900 MHz, DCS 1800 MHz,  and PCS 1900 MHz. GPRS compatibility occurs in class-12 multi-slot modality, schemes CS-1, CS-2, CS-3 e CS-4. The GPRS connection supports TCP/UDP, FTP e HTTP protocols. …

This is a GSM/GPRS-compatible Quad-band cell phone, which works on a frequency of 850/900/1800/1900MHz and which can be used not only to access the Internet, but also for oral communication (provided that it is connected to a microphone and a small loud speaker) and for SMSs. Externally, it looks like a big package (0.94 inches x 0.94 inches x 0.12 …
