- Overview

The main purpose of using wireless network is its flexibility, roaming, low cost, and high standard.

A wireless network provides a network without the use of wires because by using it you can connect your computer to the network using radio waves and can move your computer anywhere. 

A wireless network is extremely portable because of its digital modulation, adaptive modulation, information compression, and access multiplexing. Air is the medium for the wireless network and it offers you the best privacy, personal computer security than before.  

Examples of wireless networks include cell phone networks, wireless local area networks (WLANs), wireless sensor networks, satellite communication networks, and terrestrial microwave networks.

 

- Types of Wireless Network Technology

A large number of technologies have been developed to support wireless networks in different scenarios. Here are some examples of wireless networks: 

  • Wi-Fi: A wireless connection created from a wired network using a wireless router or access point. Wi-Fi can provide wireless connectivity for multiple types of internet service, such as DSL, satellite internet, and fiber optics.
  • Bluetooth: A wireless connection designed for short-range connections, typically up to 30 feet, directly between two devices without the need for an intermediary such as a router.
  • Wireless broadband (WiBB): A high-speed internet and data service delivered through a wireless local area network (WLAN) or wireless wide area network (WWAN).
  • Hybrid network: Any network that can use more than one type of connecting technology. For example, a home network that uses both Wi-Fi and Ethernet cables to connect computers is a hybrid.
  • Communications satellite: A wireless communication device in Earth's orbit that uses a transponder to send and receive data from Earth. It is primarily used to redirect communication data from one Earth-based communication station to another station.
