Telia is one of the few companies in the world to build LTE networks (Verizon is the largest). Telia and Verizon's 4G base stations, IP networks and test network equipment all come from Swedish telecom equipment manufacturer Ericsson. It is estimated that Verizon's LTE network will be commercialized in the United States no earlier than 20 10, and the full coverage time will be 20 15. Telia has a clear lead. Telia said that the new 4G network can bring 10 times faster than 3G, which means that they have achieved a speed of 60- 100Mbps, and because Sweden's land area is relatively small, Telia will easily cover more than 99% of Sweden's population with 4G signals. But in the competition with Swedish operators, Verizon has its own advantage, that is, 700MHz.
