5G - challenges and opportunities

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.
