Higher Capacity
"The technology will deliver higher capacity and speed to end user devices when eventually rolled out across the entire mobile network."
I'm sure they said similar about 4G, but it it can take minutes to open a Google map up in some parts of central London. Mobile data is like adding lanes to a road; journey times are reduced at first but eventually traffic volume increases until journey times stabilize back to what drivers would put up with before the road was widened. The cynic in me says that 5G will just result in more (ad) data per web page, hi-def movies will become higher-def, music streamers will offer higher-fi, and pretty soon we'll "need" 6G - which is good news, I suppose, for those who sell phones.
