Describe the main characteristics of transmit power control (TPC).
What will be an ideal response?
Transmit power control (TPC) is designed to reduce interference to other systems. This is accomplished by reducing the radio transmit power that the WLAN devices use. When a wireless device associates with an AP, the device informs the AP of its transmit power capability. The access point uses this data about the stations associated with it to compute the maximum power needed for the network. If other radio traffic is detected from outside systems, the AP can dynamically reduce the radio signal strength to maintain wireless communications yet not interfere with other systems. Because the AP already knows the power capability of each wireless device, it can adjust signal strength to reduce interference with other devices while still maintaining sufficient power for operation of the wireless network.

Benny is a thief who tried to break into an Automated Teller Machine (ATM) using a screwdriver, but was only able to break five different keys on the numeric keypad and jam the card reader, at which point he heard Alice coming, so he hid. Alice walked up, put in her ATM card, successfully entered her 4-digit PIN, and took some cash. But she was not able to get her card back, so she drove off to
find help. Benny then went back to the ATM, and started entering numbers to try to discover Alice's PIN and steal money from her account. What is the worst-case number of PINs that Benny has to enter before correctly discovering Alice's PIN? What will be an ideal response?
