Basic Wireless Networks Tutorial

Wireless network uses 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 in to Wireless LAN, MAN, WAN etc. They are mentioned as WLAN, WMAN and W-WAN respectively. This article gives you a brief introduction of each type of WiFi networks. We order them below according to the  size of 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.

Some Examples of Wireless Networks
  1. Mobile Network

    Mobile networks cover a land area to enable mobile communication and is 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 use IEEE802.11 standards and comes under WLAN. Examples are 802.11a, 802.11b etc. Each standards 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 5GHz frequency. 802.11n standard works in both 2.4GHz and 5 GHz frequencies.

Destination Host Unreachable - Reasons and Solutions

The error message "Destination Host Unreachable " tells that the ping request from our computer cannot find the route to the destination IP address(destination host). It means, the Packet send from your computer reached the destination network successfully but the remote gateway failed to find the destination host. So the remote gateway sends an Echo message Destination host unreachable. One major possibility for this error; there is no route listed in the remote gateway, for the packet send from your computer, to the destination host. If there is no route available, it is impossible to find the destination host and your computer will receive an error message "Destination host unreachable" from remote gateway. So one of the reason for this can be faulty routing table. If the destination host is down at the time the packet send, it may result destination host unreachable error message.
