Wireless repeater is the network component employed by the administrator to extend signals in this scenario. A wireless network is a type of network that uses radio waves or infrared signals to transmit data between devices without using cables or wires. A wireless network can consist of various components, such as wireless access points (APs), wireless routers, wireless adapters, wireless bridges, wireless repeaters, etc. A wireless repeater is a network component that extends the range or coverage of a wireless signal by receiving it from an AP or another repeater and retransmitting it to another area.A wireless repeater can be used to support new devices connected to the network beyond the AP's range.In the scenario, a startup firm contains various devices connected to a wireless network across the floor. An AP with internet connectivity is placed in a corner to allow wireless communication between devices. To support new devices connected to the network beyond the AP's range, an administrator used a network component that extended the signals of the wireless AP and transmitted it to the uncovered area. This means that he used a wireless repeater for this purpose. A wireless bridge is a network component that connects two or more wired or wireless networks or segments together.A wireless bridge can be used to expand the network or share resources between networks.A wireless modem is a network component that modulates and demodulates wireless signals to enable data transmission over a network.A wireless modem can be used to provide internet access to devices via a cellular network or a satellite network.A wireless router is a network component that performs the functions of both a wireless AP and a router.A wireless router can be used to create a wireless network and connect it to another network, such as the internet.
