The higher carrier frequency, the broader bandwidth and better transfered rate.
Is there any other opinion?

In GSM the higher frequency bands doesn’t have anything with transmission bandwidth and datarate, which actually is the same for all bands.
The need for higher frequencies is only related with the network planning, especially for using smaller cells in very populated regions.

| in fact we can not give many adv. of 1800 than 800 as the main goal of using 1800 is giving more resources to serve more users

sorry to tall u frds its not like that...
i am working in technical part of NSN..
so i think i am able to solve this doubt...
there r only two frequenciecs wher water absorption losses r very low at
arround 900 & arround 1800 mhz
if we use other frequency rather than this all signal is absorbed by water of environment (HUMINITY) so........
& remember call capacity is depend on aloocated bandwidth not on frequency.....

As other have commented the reason is to allow more users on populated areas. The radiated area using 1900 is less that with 900 so you can have more users in the same area. But 1900 is worst if you are planning to cover a wide and not populated area because you need more base stations and more money.

| this is because the 900M band is rare, so use the 1800,certainly y can use the 2.4g,depend on the frequency resource.
