## basics facts about 5G

- higher frequency is higher capacity

1 Hz means on average a capacity of 15 bit, and up to 256 bits - achieved by amplitude modulation 
1 GHZ means Gbits

optic fibre is better on any count but expensive to get to places

- higher frequency is lower/shorter coverage

- higher frequency is lower/faster latency

targeted 4ms delay - this is why conceptually new technology

- economics

opportunities versus costs

for the same 100Mb/sec capacity, optical fibre is about 45-70 usd (per client?), while FWA (Fixed Wireless Access) on 5G is about 650-1050 USD.
Therefore 5G will be used only for niche categories.

Edge computing shows up for computing on the boundary of 5G
eMBB - enhanced mobile broadband - for retail
mMTC - MASSIVE machine type commuications - for IoT
URLLC - ultra-reliable and low latency communications - for autonomous vehicles
