For example look at some of the popular UMTS bands
Band--------Uplink--------Downlink
2100> 1920 - 1980> 2110 - 2170> Named after the downlink frequencies
1900 > 1850 - 1910 > 1930 - 1990> Named after the downlink frequencies.
1700 > 1710 - 1755 > 2110 - 2155> Named after the uplink frequencies.
850 > 824-849> 869-894 > ------ both uplink and downlink are around 850 MHz.
It's easier if one criterion is used for naming the bands. My brother thought he would need a dual band phone for an operator with services in the first (2100) band.
Thank you
typical and
gunkdave. I hope you would allow me to rant some more.
UMTS Bands
Band 1 (IMT)
Uplink: 1920 - 1980 (MHz)
Downlink: 2110 - 2170 (MHz)
Band 4: (AWS)
Uplink:1710 - 1755 (MHz)
Downlink:2110 - 2155
Here is the reason why I have been so frustrated that it's making me rant again.
A phone with GSM 850/900/1800/1900 works in all 4 GSM bands.
What does a 3G spec of 1700/2100 mean? Does it mean band IV (AWS) only or band I (IMT) and Band IV (AWS). Simply put is 1700/2100 a 3G dual band or single band? I bought a Samsung (Quadband GSM) 3G (1700/2100) phone from T-mobile. If it's AWS and IMT, it should work in Japan. If it's AWS only, it won't. A call to T-mobile proved to be frustrating and a waste of time.
Can anyone shed some light on what 3G 1700/2100 means?
Thanks
