Samsung Electronics Co. will develop 5G network infrastructure for Verizon Communications under a $6.65 billion deal announced Monday. The contract runs through 2025. Samsung has developed limited 5G systems for Verizon before, and Verizon said it was excited to expand the relationship. The South Korean technology giant beat out rivals like Finland’s Nokia, which has also worked with Verizon in the past. But another rival, China’s Huawei Technologies, was off the table. The U.S. government has warned U.S. and European phone carriers against Huawei because it considers the company a security risk.
