The executive of the Swedish company, said that "it is not known if future applications will require more speed and capacity of signaling or all at once." With the focus on the region, Ewaldsson said it does not matter whether you're just starting with 4G, because the telecommunications industry is unpredictable in terms of the services they should offer. He also warned that other sectors add  demand, such as mobility, broadband and the cloud, that spans to various industries.
