Having led in mobile adoption since the $1990$s$,$ South Korea is taking preemptive action to develop a $5$G network. The government of South Korea is spending $$1\mathrm{.}5$ billion on upgrading the network, which is expected to be fully rolled out in $2020\mathrm{.}54$

With the spending of $$1\mathrm{.}5$ billion, how do you expect the aggregate demand to change in South Korea?

If the $5$G network can be successfully rolled out in $2020,$ will there be any changes in South Korea$$s short$-$run aggregate supply $($SAS$)$ and long$-$run aggregate supply $($LAS$)?$
