Re: [c-nsp] Bonding multiple 3G HWIC signals?

2010-04-14 Thread Andrei-Marius Radu 
Hi Stephen,

I think that Cisco is saying you should use different carries because
if you have 3-4 3G cards with services from the same carrier all those
3G cards will associate with the same wireless phone cell and that
cell may or may not have enough uplink bandwidth. For example if that
cell has 4 E1s for packet traffic that would only sum up to 8Mbps.
This should apply to one or multiple routers in the same location.

 I'm curious as to whether or not Cisco's 3G HWIC's can somehow be aggregated
 (through IOS or not) in order to essentially get an Nx3G amount of bandwidth
 over a single carrier's network...haven't found any luck googling.



 Cisco says the only option is to use multiple carriers, if in the same
 router (and I'm not sure whether or not to believe that):

 http://www.cisco.com/en/US/prod/collateral/modules/ps5949/ps7272/prod_qas0900aecd80600f5d.html



 The application is for sending HD video over wireless, and we'd need at
 least 3-4 3G signals to make this work.



 Does anyone have experience with doing something like this with one single
 router? (i.e. 2800 with multiple HWIC-3G-CDMA's)



 OR...Is the only option to buy a few 1841's with one 3G HWIC in each, and
 route everything back to our LAN?



 Any advice is greatly appreciated!

IANAWWANE*, but I'd be curious to know just how unique cell cites are
to a carrier in dense/interesting locations; from my small, cursory
knowledge of cell sites and associated backhaul archs, it's more
GSM/CDMA than Carrier A/Carrier B...and even then...
