Sorry if this doesn’t answer your question directly but I thought I should share my experience with satellite, with the hope that it helps you make an informed decision.
I’ve had the displeasure of dealing with a couple of satellite providers for the company I used to work
for and I will tell you a few things.
First, read you contract carefully before signing. In my experience, I never saw the service come even close to the speeds they advertised. In fact, in my experience, DSL was faster. Bandwidth was throttled during peak times. Also, there were data cap limits imposed during peak times and hefty penalties for exceeding that cap. Running something as simple as a credit card transaction took at least 30 seconds to a minute, which is an eternity for a mid to high volume retail store.
After dealing with all that, I told the CTO of my company that we should never open a retail location where satellite was the only choice.
Keep in mind this is solely my experience in the south eastern part of the US. And this was also about 6 years ago. The technology may have evolved since then. So take all this with a grain of salt.
