Small cells take over the mobile world

To meet the ever-rising demand for mobile data services operators are planning a radical change in the way mobile networks are built. Instead of traditional high-power radio basestations covering cells from 10km to 30km, networks will be made up of much more closely packed 50m to 200m small…
