[chbot] Long distance data link, advice from the guru's please

[Mark Beckett]

Yep that right, but he has another thats lower at Halswell (about 300m)
My Gridpack is on a pole on the roof to clear the 4m hedge, and we can 
get 3.5 - 4Mb/sec.


I think you'll find that the satellite uplink is probably 128Kb, and the 
down is 256/512kb.
The problem is that its limited to a total of 4GB/week.

Adding a second modem is not going to help with the total limit.


Unlike us in NZ who have poor broadband, my Australia friend complains 
when he has to plug his computer in the get faster than his 54MB WiFi ...
I imagine our American friends are probably similar, and used to fast 
almost unlimited internet.
