When they say it is not wifi and not an Aircard...well, Aircard appears to be one trademark from one vendor (Sierra Wireless) that has been appropriated like Kleenex for tissue. Translation: Either they stole exotic quantum transceiver technology from Area 51, or they are indeed using an "Aircard" by any other name, a cellular radio
They seem to imply their's is a special one made by Sony, woo-hoo, Sony isn't much of a leader in quality or technology these days.
Personally I'd look askance at any claims from one vendor that refuses to be specific when it comes to questions like "what technology are you using?" when their product is, after all, supposed to be simple technology. Might be a good product, might be a reasonable price, might be they've got phenominal rates and roaming. But the smoke and mirrors attitude usually means "there's no there there".
Can only be installed on boats? Ahuh, sure. Last time I heard a story that good it was from a satellite
internet dish provider, who swore that you couldn't install it yourself because you needed an "FCC satellite
installer license". Which, oddly enough, the FCC had never heard of, and was fairly sure had never existed.
Would you go to a fishmonger who would only sell you "FISH! It is FISH!" without being a little more responsive about the product? <G>
Everything today is about putting the hocus in the pocus. Even with cellular...AT&T rushed into data services, using the same two bands they use for voice. Ooops, ran out of bandwidth. Which is why they are buying
T-Mobile, who waited and paid a fortune for space in the (auctioned at a later date) 1700MHz band. While both are GSM...that also means equipment
from either one cannot run at full speed on the other service
, because they don't share their highest-speed bands.
So even with a cellular data sharing box (i.e. MiFi) you need to make certain the particular box you buy, will work well with the services of the carriers you will be using. Which for the Carrib would probably match the AT&T products that use both US and "world" (EU) bands, quad-band.
Or maybe that fishmonger has a new box that is really the first to use all bands, all modes, and really is a cut above the rest. You'd think they'd speak openly and proudly about that, if it were the case.
