WHAT IS THE NEED FOR SWICOM?

CURRENT IN-VEHICLE COMMUNICATION NETWORK

ARCHITECTURE

Built-in devices Add-in devices In-vehicle gateways Application hosts

CURRENT IN-VEHICLE SERVICE ORIENTEDNETWORKS

LIMITATIONS OF THE CURRENT SYSTEM

Requirement of a dedicated hardware Difficulties in deployment High maintenance cost Modification possible only through physical

intervention Difficult to reconfigure and update Space constraints

SOFTWARE DEFINED RADIO (SDR)

"Radio in which some or all of the physical layer functions are software defined"

INTRODUCTION OF SDR INTO THE PRESENT

CONTEXTSoftware Defined

Radio-evolutionSignal processing

by software components

Generic hardware with programmable processors

SOFTWARE DEFINED RADIO (SDR) TERMINAL

Delegates much of its signal processing to software components

Inexpensive and efficient

CORBA used as a message-passing technique
