How do wireless repeaters function in a network?

Wireless repeaters play a crucial role in extending the coverage of wireless networks. They function by receiving signals from an existing wireless access point or router and then retransmitting those signals to areas that the original network may not reach effectively. This process helps to amplify the signal and increases the overall range of the network, ensuring that devices located further away from the router can still maintain a stable and reliable connection. By effectively extending coverage, wireless repeaters help to avoid dead zones and improve connectivity in larger spaces or areas with obstacles that can weaken a signal.

Other options do not accurately describe the primary function of repeaters. Routing traffic between devices pertains more to network management and functionality that requires more complex decision-making, while repeaters do not inherently increase the speed of the network; their main goal is to enhance coverage. Managing network access control involves security and permissions rather than the basic functionality of signal retransmission.
