Need Help/Info re. Sun Cellular Bandwidth

[nuno]

---

At work, I was given the task by our boss to find out which bandwidth Sun Celluler uses including its upstream and downstream. Info I found on the net says they use 1800Mhz, other says 1900Mhz. I tried calling up the company's customer service but was not given any information.

Any information will really be appreciated..

(I am also interested to know what upstream/downstream is)

Thanks

1800 MHz is not the Bandwidth but only the Frequency used by the system.

Thanks Scarab.
Therefore is it the upstream/downstream that uses bandwidth?
Any info will really be appreciated..

afaik, Upstream is the bandwidth of the system when transfering data from your mobile phone to the cell site, and downstream is the bandwidth from the cellsite to your mobile phone...
