I am trying to understand that!
EX.
Frequency band Uplink Band Downlink band Bandwidth
B3 1710 - 1785 MHz 1805 - 1880 MHz 75 MHz
As I know the B3 is the band which is use on region. uplink band & downlink band are how much we can send and receive. But bandwidth I do not understand it.
Please correct if I am wrong!
Hello Ihab,
Downlink and Uplink Bands that you've listed are in fact frequency ranges that can be used for communication with the base station (network), not throughput (data exchange rate). And, similarly, Bandwidth is the span of that range:
Uplink Band: 1710 - 1785 MHz (it spans a range of 75 MHz)
Downlink band: 1805 - 1880 MHz (same here)
Best regards,
Ida
Hi Ida,
You are really perfect!
I understand that now totally good but I want to make sure about other things which you connected to.
Downlink Peak Rate 26 kbit/s
Uplink Peak Rate 66 kbit/s (multi-tone)16,9 kbit/s (single - tone)
Downlink Data rate 250 kbps
Uplink Data rate 250 kbps (multi-tone), 20 kbps (single tone)
Is peak rate and data rate the same?
As you explained that data rate is throughput. In other word, it is how much data I can send and receive?
Right or??
Hello Ihab,
Throughput or data rate is the actual amount of data that travels across the link in a given period of time. In your example it is measured in kilobits per second. And it's measured separately on uplink and downlink. The peak rate would be the top or maximum value archived during a period of time.
