Hi Tony,<div><br></div><div>I'd be interested to hear about this too as I've been doing some work in the last few weeks with the 881G with Telstra and it's been pretty good. �It would be good to know for sure which HWIC to use. �That said,�I can't imagine myself ever deciding to use Optus for 3G connectivity anywhere I was serious enough to put anything that had a HWIC in.</div>

Hi all,<br>
<br>
We're looking at wireless backup options, specifically HWIC's in Cisco routers. The question I have is in regard to the frequencies used by the providers and the HWIC required. It would appear that Telstra use 850MHz and Optus use 900MHz (and possibly 2100MHz).<br>
<br>

<br>
It says that part HWIC-3G-HSPA supports "HSPA: 850, 1900, and 2100 MHz"<br>
and that HWIC-3G-HSPA-G �supports "HSPA: 900, 1900, and 2100 MHz ".<br>
<br>
This leads me to the conclusion that I would need to purchase a different HWIC depending on which provider's network I'm wishing to use (850 or 900) ?<br>
<br>
This seems very annoying to me, because the specs on the PCEX-3G-HSPA-G modem for the 881G routers says it does all of 850/900/1900/2100 (ie. it should do both Telstra & Optus with same modem).<br>
<br>
Is this correct ? Does anyone have practical experience with this ?<br>
<br>
<br>
Thanks,<br>
