HSDPA (High Speed Packet Downlink Access)
A dream beyond dream. HSDPA is also called 3.5G. Why 3.5G? Well the theory is that HSDPA doesn’t utilizes its ful potential. HSDPA offers 1.8 Mbit/s to 14.4 Mbit/s data rate in downlink direction.
Ciphering algorithm used in UMTS. A replacement for A5.
KASUMI is a block ciphering algorithm that uses a 128 bit key and generates a 64 bit output stream from a 64 bit input stream.
