Frequently Asked Questions

Wireless networks are computer networks that are not connected by cables of any kind and uses the wireless data connections between network nodes. The use of a wireless network enables enterprises to avoid the costly process of introducing cables into buildings or as a connection between different equipment locations. The basis of wireless systems are radio waves, an implementation that takes place at the physical level of network structure.

There are FOUR main types of Wireless Networks :-

  • Wireless Local Area Network (LAN): It links two or more devices using a wireless distribution method, providing a connection through access points to the wider Internet.
  • Wireless Metropolitan Area Networks (MAN): It mainly connects several wireless LANs.
  • Wireless Wide Area Network (WAN): It covers large areas such as neighboring towns and cities.
  • Wireless Personal Area Network (PAN): It interconnects devices in a short span, generally within a person’s reach.


Wireless technologies employ radio waves and/or microwaves to maintain communication channels between computers. While many technical details behind wireless protocols like Wi-Fi often aren't important to understand, knowing the basics can be very helpful when configuring a network and troubleshooting problems.

There are four main kinds of Wireless which are available in the market :-

  • Fixed Wireless- Fixed Wireless is the operation of wireless devices or systems in homes and offices, and in particular, equipment connected to the Internet via specialized modems.


  • Mobile Wireless- The mobile wireless is the use of wireless devices or systems aboard motorized, moving vehicles; examples include the automotive cell phone and PCS (personal communications services).


  • Portable Wireless- It is the operation of autonomous, battery-powered wireless devices or systems outside the office, home, or vehicle; examples include handheld cell phones and PCS units.


  • IR Wireless- It is the use of devices that convey data via IR (infrared) radiation; employed in certain limited-range communications and control systems.

There are a number of Wireless Devices available today. To help prevent conflicts between all of the different wireless devices each category of devices have a designated frequency area (spectrum).

There are two types of wireless networks: infrastructure and ad hoc. The infrastructure network is most likely the type of wireless setup which is in the home or office. It’s laid out similarly to a wired network, but without wires.

The basic wireless, peer-to-peer network consists of these components:

Wireless router: The heart of the wireless network is the wireless router. Like a wire-based network, the hub is a central location that all computers connect to, providing the computers with network access.

The wireless hubs now available also serve as routers. Well, officially, wireless hubs are gateways, not routers, but they’re called routers. They’re also called access points.

Wire-based connections: Almost every wireless router has one or more standard, wire-based Ethernet port. One port is used to connect the router to a broadband modem. Other Ethernet ports might be also available, allows to connect standard wire-based networking to the wireless hub.

Wireless NIC: The computer needs a wireless network information card, or NIC, to talk with the wireless router. A laptop comes standard with a wireless NIC, but for a desktop PC, there is a need to get a wireless NIC as an option. It is an installed internally as an expansion card, or one can use various plug-in USB wireless NICs.
