480Mbps. The following requirements should be followed in designing PCB layout. USB_D+ and USB_D- signal lines should have the same length, and should be parallel; avoid right  angle wiring.  USB_D+ and USB_D- signal lines should be wrapped with GND at the ends.  USB2.0 differential signal line should be laid at the signal layer closest to the ground layer.  USB signal line shall be far away from stronger interference signal, such as power supply.

If SIM_DETECT is at low level, which indicates SIM card is not inserted, the module will not register it  to the network. Note: the default of +MSMPD parameter is “1”.SIM_DETECT is the detection signal. While the module first power on or plug after that, SIM_DETECT will detect if the SIM card is existing or not. Just only if the SIM_DETECT is low level, the module will cannot read SIM card. 5.6 Digital Audio L830-EA M.

7.5 Antenna Design 7.5.1 Main Antenna Design Requirements (1) Antenna efficiency Antenna efficiency is the ratio of the input power and radiant power. Because of the antenna’s return loss, material loss and coupling loss, the radiant power is always lower than the input power. The ratio is recommended to be > 40% (–4dB). (2) S11 or VSWR S11 shows the matching degree of the antenna’s 50 ohm impedance, which affects antenna efficiency to a certain extent.
