The accommodate has just revealed its two newest mobile hotpots, the AirCard 754S and 753S unlocked. The former supports dual-carrier LTE, while the latter handles dual-carrier HSPA+,

enabling up to five WiFi devices to surf on either of the fastest two mobile super highways. We all know that the 753S can hit downlink rates as high as 42Mbps (and upload rates near 5.76Mbps) on a DC-HSPA+ network, while the 754S unlocked can reach 100Mbps (down) / 50Mbps (up) while operating on an 4G-LTE network. Both of these are right around the size of a deck of cards, and no software installation is required to get ’em working. There’s also an integrated LCD that provides a look at WiFi access information, battery life, network signal strength, and the number of devices connected, with audible alerts and a web admin interface available as well.

Moving right along, the other operators will be offering yet another new one from Sierra Wireless this March: the AirCard 319U unlocked USB modem, a device we recently spotted in the FCC’s database. This one promises download speeds of up to 42Mbps and upload speeds approaching 5.76Mbps, with a swiveling design that allows the body of the modem to be tucked up against the side of the notebook and protects it from being damaged by accidental bumps. The LTE-friendly AirCard 320U is the USB version of the 754S hotspot shown above, with an articulating and pivoting hinge that works with the widest possible variety of USB port placements, and if all goes well, it’ll ship during Q1 2012 for an undisclosed rate. Sierra wireless plans on having Mac and PC support for the whole lot, and we’ll be digging for details surrounding price and availability.
