Basic Wireless Networks Tutorial

A wireless network uses the wireless signal to communicate between devices connected in the network. Here we use signals like radio waves, microwaves or infrared to send and receive data between two devices. Just like normal network types, they too classified into Wireless LAN, MAN, WAN etc. They are mentioned as WLAN, WMAN, and W-WAN respectively. This article gives you a brief introduction to each type of WiFi networks. We order them below according to the size of the area they cover.

Types of Wireless Networks
  1. WPAN

    Wireless Personal Area Network (WPAN) uses to transfer data between two devices which are in short distance. Examples are Bluetooth and infrared. Some of the applications like WiFi keyboard, WiFi mouse etc. To learn more about it visit the link below.

  2. Wireless LAN

    WLAN uses IEEE802.11 standards to communicate between devices. It is also called WI-Fi and operates in different frequencies like 2.4GHz and 5GHz. To learn more about WLAN, click on the link below.

  3. Wireless MAN & WAN

    These two types of networks cover a large geographical area.

Some Examples of Wireless Networks
  1. Mobile Network

    Mobile networks cover a land area to enable mobile communication and are cell shaped. Different cells use different radio frequency to avoid any possible interference with neighboring cells. You can categorize mobile network under W-WAN.

  2. Wi-Fi

    As we explained above, Wifi uses IEEE802.11 standards and comes under WLAN. Examples are 802.11a, 802.11b etc. Each standard has its own frequency and speed. For example, 802.11n is faster than 802.11a/b and g standards. Both band g standards work with 2.4 GHz frequency. However, 802.11a works at the 5GHz frequency. 802.11n standard works in both 2.4GHz and 5 GHz frequencies.
