SMPP(Short Message Peer to Peer) is a standardized protocol that handles the communication between SMSC and other SMS entities. It is an interface between the SMSC and NON-PLMN SMEs ( Short Message Entity). Typically it specifies the interface used between the SMSC and ESME ( External Short Message Entity) systems. This SMPP protocol may be implemented over a variety of underlying communications protocols X.25 or TCP/IP over internet or leased line by pluging in the IP cables into the SMPP server and opening the correct SMPP port.

Posted by admin on July 2nd, 2010
In Mobile Network, microwave radio are used to transfer data between BTS sites, between BTS and BSC or MSC. There are both advantages and disadvantages of using Microwave Radio links. Microwave radio communication is normally used for sites which are located in rural areas where site accessibility is difficult. It is because the cost of Microwave Radio communication installation and commissioning is cheaper and it's also easier to implement than other transmission technology such as Optical fiber. The disadvantage of Microwave Radio over Optical fiber is the data transmission speed and interference. ....
