H2: Think of a scenario where pure ALOHA performs better than
slotted ALOHA and describe this scenario ("better" in terms of fewer

H3: Describe two properties of the wireless environment that are
not present in the wired environment (i.e., why do we need different
protocols for wired and wireless networks?).
H4: Suppose you were deploying a network in your house/apartment/dorm

be an advantage to deploying a wireless network?
