Short message service (SMS) is a service to enable short text messages transmission between wireless device communications. Short text messages are sent in the form of alphanumeric combination. SMS uses fixed length alphanumeric text encoding which is 7 bits per character or 8 bits per character or 16 bits per character depend on the kind of alphanumeric used. Widely used ASCII system encoding use 7 bit per character. SMS that use this encoding system only contains maximum 160 characters for each SMS packet. To increase the SMS packet capacity, other encoding system can be used to lessen the number of bits. <br />

In this final project, the writer will try how LZWs modified will work if this algorithm used for compressing data using emulator. This modified felt necessary to be done to cover the weakness of dictionary techniques that generally not good for compressing small data and need sendings protocol like SMS. This final project also contains planing of making the program using UML, the result from simulation with their grafic, and the analysis about the advantages and disadvantages of this LZW modification. <br />
