Ericsson today said it has achieved interoperability between a commercial LTE device and LTE network, claiming the move to be a world-first. The Swedish vendor used Samsung's new LTE dongles and its own live LTE network in Stockholm. "This is the first time a commercial, standard compliant LTE device demonstrated full interoperability with a live network," said Johan Wibergh, senior VP and head of networks at Ericsson, in a statement.
