LTE Data rates, frequency
and bandwidth.
In digital computing data rates are computed as number of bits that can be transmitted Over The Air
(OTA)
in one unit of time. The comparison of data rates between 3G and 4G technologies is discussed below.3G/4G data rate comparison.
Generation | 3G | 4G |
Technology | UMTS, HSDPA | LTE |
Uplink (Theoretical) | 5.7 Mbps | 50 Mbps |
Downlink (Theoretical) | 14 Mbps | 100 Mbps |
Bandwidth | 5 MHz | 20 MHz |
LTE Data rates
The data rates shown in table above are in units of
In practical, the data rates are generally reduced to one fourth of mathematical figures. There are several bottlenecks in modem
Mega(10^6)
bits per second. The rates are calculated using mathematical models.In practical, the data rates are generally reduced to one fourth of mathematical figures. There are several bottlenecks in modem
physical layer
and data link layer protocols that can effect actual data rate. These high data rates are highly suited for HD or 1080p videos, gaming, voip, web surfing etc.
