The 5G rollout is reportedly slowing.

The Wall Street Journal reports that equipment makers are seeing a slowdown in infrastructure spending, including in the U.S.

Executives told the Journal that telcos want to see whether 5G will actually prove profitable before they invest significantly to further develop their infrastructure. They also cited local government reticence to the developments over the many extra antennae that 5G networks require.

One bright note: The delayed T-Mobile/Sprint merger led the former to postpone new 5G orders, the Journal reports. Now that it's been approved, it may resume spending.
