Havnt tested thoroughly, I think the ping times are probably the worse thing about them.
I remember we had problems with ping times being up in the hundreds, sometimes 350-600ms, can't remember what sort of speeds we had sorry.
"Latency- why is it a big deal for Satellite Internet?
It is a common perception that TCP does not work well over long-delay networks, particularly satellite. Although this is true in comparison to traditional T-1 or DSL lines, latency can be minimized to an extent where even most mission-critical applications can work perfectly over satellite.
Latency is defined as the amount of delay, measured in milliseconds, that occurs in a round-trip data transmission. Latency is unavoidable in any Internet connection and it can only be minimized using a netter managed network. Not directly related to speed, latency can be an issue with all networks including satellites.
What causes latency over satellite links?
Latency is caused by several factors including the number of times the data is handled along the transmission path (by routers or servers for example). The GEO satellites used for two-way Internet service are located approximately 23,000 miles above the equator. This means that a round-trip transmission travels 23,000 miles to the satellite, 23,000 miles from the satellite to the remote site, and then as the TCP/IP acknowledgment is returned, another 46,000 miles on the return trip for a total round trip of over 90,000 miles. Depending on your latitude, this distance to the satellite could be even greater.
Each time a data packet ‘hops’ (i.e. handled by a device along the path) several milliseconds of latency are introduced. The physics involved account for approximately 550 milliseconds of latency, a limitation shared by all satellite providers. This latency can negatively affect the performance of many business applications and software that requires real-time user input. "
