The US city of Seattle has been named as the inaugural winner of Bloomberg's American Cities Climate Challenge, an ambitious program which helps cities achieve their environmental and sustainability goals.

US telecommunications operator Verizon has announced that it plans to rollout 5G fixed wireless services in five major cities across the country in 2018. The development would represent the first application of 5G wireless in the United States.
