Data rate
Current terrestrial radio transmission technologies for UMTS, propose data rates up to 2 Mbit/s in both directions.
Actually, the data rate depends on the mobility condition. This figure corresponds to a static or low mobility condition
of the terminal with respect to the base station. It refers also to a condition of short distance to the base station. This
corresponds typically to indoor and low range outdoor environment. Data rates as high as 384 kbit/s will be supported
in outdoor environments. UMTS further distinguishes between urban/suburban outdoor and rural outdoor environments
with achievable data rates of 384 kbit/s and 144 kbit/s respectively. For satellite, the need for high data rate depends
firstly on the services to be offered and also on the user mobility condition regarding the base station. The lower the
mobility, the higher the data rate is desirable.
