Sony Ericsson MD400 User Manual

The MD400 has two built-in antennas and the MD400g has an additional GPS antenna.

1. Main - GSM/UMTS/HSPA (transmit and receive)

2. Diversity - UMTS and HSPA (receive only)

3. GPS - Global Positional System (MD400g only) (receive only)

The MD400g Mobile Broadband Modem contains a Global Positioning System (GPS) receiver. GPS 
is a satellite-based navigation system made up of a network of 32 satellites orbiting the Earth. GPS 
works anywhere in the world, 24 hours a day. 

To access the GPS features of the MD400g, select View 

 GPS in Wireless Manager. If you are 

using other software, for example, supplied by your mobile operator, please consult the 
documentation for that application. 

GPS data is provided over the Sony Ericsson GPS Port. This is a Windows virtual COM Port. When 
you install the MD400g, Windows will assign a number, for example COM23. To link a third-party 
GPS-enabled application to your MD400g's GPS receiver, you may need to access the application 
settings and select the COM port number that Windows has allocated. This is displayed in the GPS 
main screen. To view the COM port information select View 

 GPS. This information is also 

available in Device Manager. 

The data that the GPS device provides, is in Nautical Marine Electronics Association (NMEA) 
format. This format is commonly understood by GPS-enabled applications.

For more information on GPS, refer to your Wireless Manager User Guide.

The network subscription you use in conjunction with your MD400 depends on the functions and 
features that are available from your network operator. Contact your network operator or service
