# Axel asks Andreas if he would like to join them for a barbecue.
# Axel's house is right in the neighborhood and the weather is fine.
# Andreas agrees, so he drives to a close store to buy some barbecue
# skewers.
#
# What happens: While driving, a different cell (mounted atop the
# store) becomes better.

# While Andreas is walking into the store, Axel asks, if he could also
# bring some beer. Andreas has problems understanding him: "I have a
# bad reception here. The cell tower is right atop the store, but poor
# coverage inside. Can you repeat please?"
#
# What happens: Inside the store the close cell is so bad, that
# handover back to the previous cell is required.
# bts 1 becomes bad, so bts 0 helps out:

# After Andreas bought skewers and beer, he leaves the store.

# bts 2 becomes better:
# Andreas drives down to the lake where Axel's house is.
#
# What happens: There is a small cell at Axel's house, which becomes
# better, because the current cell has no good comverage at the lake.

# Andreas wonders why he still has good radio coverage: "Last time it
# was so bad". Axel says: "I installed a pico cell in my house,
# now we can use our mobile phones down here at the lake."
