ISPs are supplying routers today so you don't see as much action there as you used to.
As to IoT, would you include Amazon and Google devices? (Echo?)
What was the IoT and Smart Router market size and revenue in the United States in 2017? What is the projected CAGR in both these cases? Also, what is the forecasted value in 2022 or 2023? Any help or suggestions would be appreciated.
P.S. Please quote data from legitimate sources
Thanks in advance!
