AT&T this morning announced first two devices 4G LTE devices, both Mac compatible: A 4G LTE mobile hotspot and a 4G LTE USB modem. If you live in any of AT&T’s five 4G LTE markets (Atlanta, Chicago, Dallas, Houston and San Antonio, with more coming by the year’s end), you can take advantage of 4G LTE speeds. Those living outside the initial 4G LTE coverage needn’t worry because AT&T, as they say, will have the only combo LTE/HSPA+ network and both devices feature HSPA+ support as a fallback technology. “Our customers will receive a more consistent mobile broadband experience that supports simultaneous voice and data connections and higher speeds than others can provide outside their LTE footprint”, AT&T argues. More on the devices, availability and price points after the break.
