You want your computer to be able to resolve a host name for a server on your network to its IPv4 address 3 answers What is the transmission medium used for wireless networks?Wireless communication is also referred to as Unguided Media or Unbounded transmission media. In this mode, no physical medium is required for the transmission of electromagnetic signals. In wireless communication, we can transfer our message through the air, water or vacuum i.e. Infrared, Radio wave, Microwave wave.
What is wireless signal transmission?Wireless transmission is a form of unguided media. Wireless communication involves no physical link established between two or more devices, communicating wirelessly. Wireless signals are spread over in the air and are received and interpreted by appropriate antennas.
Are radio waves that provide a high speed signal transmission?Microwaves are radio waves that provide a high speed signal transmission.
What is a wireless transmission media that can travel at the speed of light?Wireless optical networks could provide gigabit-per-second data transfer. A wireless network that uses reflected infrared light instead of radio waves has transmitted data through the air at a speed of one gigabit per second–six to 14 times faster than the fastest Wi-Fi network.
