Chapter 1 – Universal Socket Connectivity Design Considerations Noise Suppression Design Considerations Engineering noise-suppression practices must be adhered to when designing a printed circuit board (PCB) containing the SocketModem module. Suppression of noise is essential to the proper operation and performance of the modem itself and for surrounding equipment.
Chapter 1 – Universal Socket Connectivity Electromagnetic Interference (EMI) Considerations The following guidelines are offered to specifically help minimize EMI generation. Some of these guidelines are the same as, or similar to, the general guidelines but are mentioned again to reinforce their importance. In order to minimize the contribution of the SocketModem-based design to EMI, the designer must understand the major sources of EMI and how to reduce them to acceptable levels. 1.

Chapter 2 – SocketModem HSDPA Operating Modes The table below briefly summarizes the various operating modes. Mode Normal operation Function GSM / GPRS / UMTS / HSDPA SLEEP GSM IDLE Power saving mode set automatically when no call is in progress and the USB connection is suspended by host or not present. Software is active. Once registered to the GSM network, paging with BTS is carried out in order to achieve synchrony with the GSM network. The repetition rate depends on the parameter BSPA_Multiframe.
Chapter 2 – SocketModem HSDPA Turn off the Module Using AT Command The best and safest approach to powering down is to issue the AT^SMSO command. This procedure lets the module log off from the network and allows the software to enter into a secure state and safe data before disconnecting the power supply. The mode is referred to as Power-down mode. In this mode, only the RTC stays active. After sending AT^SMSO do not enter any other AT commands.
