Importance of Wireless Technologies
Wireless connection to internet is very common these days. Often an external modem is connected to the Internet and other devices connect to it wirelessly. This Removed the need for last mile or first mile wiring. There are two ways of connecting to the Internet wirelessly – Wi-Fi and WiMAx. What are Basic Wireless Devices? 1. Wireless Access Points, 2. Wireless Network Interface Card (WNIC), 3. Wireless Antennas • Wireless Access Points In the wireless networks, you’ll find a central component such as a switch that’s there to connect hosts together and allow them to communicate with each other. Only that device is known as a wireless access point (AP) instead. • Wireless Network Interface Card (WNIC) Every host you want to connect to a wireless network needs a wireless network interface card (WNIC) to do so. Basically, a wireless NIC does the same job as a traditional Ethernet NIC, only instead of having a socket/port to plug a cable into; the wireless NIC has a radio ant
