Swedish cell phone carrier TeliaSonera has powered up what it calls the world’s first commercial Long Term Evolution (LTE) 4G network in Stockholm, accessible via Samsung cellular USB modems.

The Ericsson-supplied network supposedly can run up to 100 Mbps when maxed out, though real-world speeds will be nowhere near that number.

Last month, several major telecoms around the world–including TeliaSonera, Orange, AT&T, Telefonica, Verizon, and others–finally agreed on a standard for voice and SMS communication over LTE 4G networks, in an effort to ensure that they’re used for more than just faster Web browsing and other data services.

Verizon is still expected to be first out of the gate with LTE in the U.S. sometime in the second half of 2010.
