What is a primary goal of using Transmit Power Control (TPC)?

  1. To boost signal strength across the network

  2. To maintain optimal power levels without interference

  3. To extend coverage areas of access points

  4. To simplify network management

The correct answer is: To maintain optimal power levels without interference

The primary goal of using Transmit Power Control (TPC) is to maintain optimal power levels without interference. TPC is a technique employed in wireless communications to dynamically adjust the transmission power of access points or wireless devices. By regulating the output power, TPC helps to ensure that the signal strength is sufficient for communication without causing unnecessary interference to other devices operating on the same frequency. Maintaining optimal power levels is important for several reasons. It helps to reduce co-channel interference, which can degrade the performance of nearby wireless networks. By minimizing interference, TPC can improve overall network efficiency and capacity. Additionally, optimizing power usage contributes to energy savings, as devices do not operate at higher power levels than necessary, which can also prolong battery life in portable devices. Other options may suggest increasing coverage or boosting signal strength, but these approaches can lead to interference problems if not controlled. Simplifying network management, while beneficial, is not the core function of TPC; rather, it is primarily focused on managing transmit power for quality communication.
