Small Cell Network 320
Small cells: fiber: Exchange: Cloud RAN: Core: Internet or PSTN. I believe Verizon has made the decision to spend ~$20B and add enough small cells to cover 1/3rd to 1/2 of the U.S. The major construction will be from 2019 to 2022. 

At the edge, 100,000-300,000 new small cells will provide both LTE and 5G service to perhaps 40M homes. They expect to do well enough to extend the build across the United States. All will have 5G millimeter wave fixed access. It will use the 28 GHz band and TDD coding. Likely speed will be ~ 5 gigabits, peak, shared. Most homes will be able to access a gigabit almost all the time because generally the cell will be lightly loaded. 

Latency will be under 10 milliseconds but not the 1 ms highly touted. Putting the intelligence back in the cloud makes 1 ms impractical. To get 1 ms, a massive network of "edge computing" would be needed. Neither Verizon nor any other telco has publicly committed to building that edge computing net. The cost would be massive and the market for 1 ms isn't apparent. Virtual reality is designing for 10 ms. Even the connected car doesn't need to go that low. João Barros of Veniam tells me, "3ms latency is enough for even the most stringent connected vehicle applications." 

When I saw both Verizon and AT&T planning cloud RAN, I knew 1 ms wasn't happening for a decade or more.

5GW News

dave rightStarting July 2017, all new articles are at wirelessone.news. The pols and the marketing folks have made "5G" a meaningless term so the name doesn't fit reporting on advanced wireless. This will stay so old links work. I've reported broadband since 1999 and now is the time for gigabit wireless. Catch a mistake or have news? Email me please. Dave Burstein
