Frequency Band:

There are a few variants of 4G LTE networks which are currently deployed in various countries or territories.  

Type C supports the 4G LTE networks in China as shown in the table below.

Type E supports the 4G LTE networks deployed in the Europe, Middle East, Africa, Korea, Southeast Asia, Hong Kong, and Macau. The table below shows the details of the wireless technologies and the bands and frequencies supported.

 Application:

The concept diagram below shows a simple VoIP network for call center application.  It consists of a softswitch/IP PBX and VoIP clients such as an IP phone, a call center operator, and GoIPs.  All VoIP clients are configured to register to the softswitch/IP PBX.  For the GoIPs, each channel is inserted with a valid SIM card in order to access the 2G/3G/4G network.  Both incoming and outgoing calls between the VoIP and 2G/3G/4G networks can now be realized.
