Several companies develop radio modems that are compatible to their existing radio network alone. An attempt is being made to remove this incompatibility between radio systems in a wireless network by developing a radio modem which can be used with any radio that follow certain specifications. The radio modems being developed communicate with each other using a generic protocol.

The Radio Modem essentially includes an Intel 8031 microcontroller and the nessessary components. The main functions of the modem are as follows
 

• Protocol translation from RS232C to our own generic protocol over the radio.
• Buffering of input and output packets
• Voltage level translation
• Error detection
• Security and Data Encryption
• Collision Management
 

The communcation routines coded in C/C++ will be made available to the user as library files. The user can create his own applications using the primitives. At compile time, these library files have to be included.
