5G is  slowly and surely getting rolled out across the US in some cities   and that can get speeds upto 400 megabites /sec is a huge deal. What we have now is 4G LTE delivering somewhere upto 20 megabites/sec and the 5G will blow every speed out of the water. Now, the catch like any thing too good to be true always comes with a catch and that is that these speeds are made possible by some clever work around done by the science team to find ways to dissect the already existing bandwidth and using the newly opened up   bandwidth to deliver the video and high processing required games and such. The 5g speed is a huge task to try and deliver this much speed to so much demand. Everyone from your neighbors grandma wants this speed , now what they do with it is a different subject altogether , but they want it!

Atlanta, Charlotte, Dallas, Houston, Indianapolis, Jacksonville, Louisville, Oklahoma City, New Orleans, Raleigh, San Antonio and Waco are all the cities that AT&T is now rolling out 5G and others will soon follow.The current makeup of the spectrum between 700 Mhz and 2.6Ghz is not divided as closely like the mm wave bands. The 28Ghz and 38Ghz bands are currently available with spectrum allocations over 1Ghz. The mm wave bands was thought useless due to effect off rain but due to shear demand of these formerly useless bandwidths are getting a closer look.

Rain effects are not too much to totally disregard that much bandwidth and hence the mm waves are putting to good use in spite of its drawbacks that rendered them useless in the past.
