Speed is another critical concern, and Kymeta advertises the ability to support data-transfer speeds faster than 100 Mbps. For comparison, this is roughly twice the speed of the fastest dome-based satellite-
communications system, Inmarsat’s Global Xpress. However, Olsson warns that there are multiple places from which speed can get sapped. For example, Kymeta uses iDirect X7 satellite modems, which have maximum download speeds of 65 Mbps, meaning that speeds can be limited by upstream and downstream hardware. Also, as with regular satellite communications, Kymeta’s mTenna technology typically downloads data faster than it transmits, but this metric currently can’t be quantified.
