How are wireless networks connected?
Computers, tablets, and other devices connect to a wireless network via a wireless access point or wireless router. In Wi-Fi-based wireless networks, the access point or router acts as an Ethernet switch. All devices connect to the router, rather than directly with each other.
How does WiFi communicate?
Wi-Fi uses radio waves to transmit information between your device and a router via frequencies. Two radio-wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz.
How are wireless devices connected to the network?
As with other forms of network communication, before transmissions between devices can occur, the wireless access point and the client must first begin to talk to each other. In the wireless world, this is a two-step process involving association and authentication.
Is it possible for two devices to connect to the same WiFi?
NB: If the client A & B are close enough to hear each other, it would be possible for them to communicate directly, but implementing the communications like this would introduce a lot of complexities. A great primer on WiFi is Matthew Gast’s book 802.11 Wireless Networks: The Definitive Guide (see the link for a “copy”). In particular Chapter 4.
How does wireless communication work and how does it work?
What is wireless? Wireless is a way of transporting signals without any wires or optic fibers. Signals propagate through free space in this case. Often, the term wireless, refers to wireless communication. This is a way of transferring information between devices that are not connected with wires.
What do I need to enable wireless communication?
Several components combine to enable wireless communications between devices. Each of these must be configured on both the client and the AP. The Service Set Identifier (SSID) Whether your wireless network is using infrastructure mode or ad-hoc mode, an SSID is required.
