• Higher is better
•Measured in dBm (for example +10dBm)
Receiver Sensitivity
• How well can you hear?
• Lower is better

stations
• The hub to relay all network communications,
translating frames between a wireless medium
and a wired medium
• Given a service set identifier (SSID), which
becomes the network name for the users
• Sends out beacons to let stations know there is
an access point they can connect to
Stations
• Computing devices with wireless network
interfaces
• Stations associate with an AP to join a network
• Stations listen for beacons to understand if any
traffic is available
• Because stations know when the next beacon is
coming, they can go to sleep during this wait
period and wake up in time for the next beacon
• Stations can access the Internet through the
access point connected to a network
