a
For speech transmission (values for base stations, mobiles do not perform that good).
b
For 384 kbit/s data transmission (values for base stations, mobiles do not perform that good).
c
SNR = −16 dB (received power is 16 dB below thermal noise power).
d
Depending on coding rate and sub-carrier modulation.
e
Wireless access in vehicular environments (WAVE), e.g., car-to-car communication.
f
+44.8 dBm EIRP is for the United States, additional limitations apply per FCC 47CFR [B8], 90.375.
The cellular GSM system uses a combination of FDMA and TDMA (with eight timeslots). On the
contrary, UMTS is based on a combination of FDMA and CDMA.
