The device is a soft modem, which means that unlike hardware modems, it relegates most of the computational responsibilities to the system processor. This allows such modems to be smaller than hardware modems, and thus far more suited for laptops and notebook computers. They also consume less power and require no additional power supply, drawing power from the laptop device itself, which is another reason why mobile device manufacturers use them. The modem connects and communicates with the host computer via a PCI Express slot, which allows for 2.5 Gb/s bit rate speeds. The single DAA design means that it can be used anywhere in the world without any problems.
