A flexible PCB gives you an ultra flat shape and the freedom to glue the embedded GSM antenna inside your box, even it has a rounded shape. This embedded GSM antenna is ideal for use with cellular modules with Assisted GPS functionality on board where only one antenna connection is available. The antenna has been designed in a flexible material with a rectangular form -factor and cable connection for an easy installation. The embedded GSM antenna works on different plastics and thickness.

DTMF decoding by GSM modem
DTMF decoding by GSM modem http://ow.ly/1gZU6
GSM Audio Codec & DTMF. Why the Half Rate Codec could force trouble?
The DTMF signal is generated by a separated source, typically a landline (corded) phone, and sent to the input lines of the module (Uplink path). The frequencies couples, sent on the voice channel , are digitised, encoded and sent by the digital transmission system. In the receiving device the signal would be reconstructed, but since […]
