WIRELESS NETWORKING

Wireless Networks

Wireless networks are computer network that are not connected by cables of any kind In simple words. when two or more devices are connected without any networking cable, It is called wireless networking. From cell phone, to simple home wireless internet connection, Bluetooth and more, everything comes under wireless networking.

Wireless Networks:

Ir DA: Infrared Data Association

Data Association has developed a standard where data is transmitted via Infrared light waves It is a protocol where beams are used in the Infrared lights spectrum. In case of Ir DA, as the data transfer is done through infrared, you can send data to one device at a time.

 Bluetooth:

Bluetooth uses 2.45 gigahertz radio waves to share data between devices. The technology is limited to a short distance of 10 ft but it can cross walls in order to transmit data This also communicates without wire. The figure shows the various Bluetooth versions.

Home RF:

Horne RF was designed for home radio frequency work group and it is a specification that works for home devices. It has 6 voice and 1 data channel.

The network is slow and works in a limited range but it is cheap. Data channel of 802.11 wireless-Ethernet specification by the IEEE is used for the transfer and it can only be used for computer. In case you need to connect the printer, you first need to connect it to the home computer.


Types of Wireless Network:

WLAN


Wireless Local Area Network also known as WLAN offers wireless network Communication over a short distance. It uses radio or infrared signals instead of traditional network cables. It allows mobile users to connect to a local area network through wireless connection. Most commonly used WI-AN protocols are Wi-Fi d Bluetooth.



Wireless Ad Hoc Network

A Wireless Ad Hoc Network is a decentralized type of wireless network that does not rely on pre-existing infrastructures like wired networks, routers or access points in managed wireless networks. It is particularly helpful in sharing files or data directly from one device to another but have no Wi-Fi connectivity.

Wireless WAN

A wireless wide area network or Wireless WAN is a special type of network that gives out signals within a range of several miles to a moving or stationary device. It is commonly known as "Wireless Broadband" or "Broadband Wireless". This type of larger network often requires some type of encryption or security that a local area network may not require. Example Skype Wi-Fi.

Wireless Fidelity (Wi-Fi)

Wireless Fidelity  is a technology that sends radio waves to offer network connectivity. A Wi-Fi Connection can be established by using a wireless adapter that creates hotspot. Hotspot is an area in vicinity of a wireless router which is again connected to the network and permits users to access internet connectivity. This technology is based on the 802.11 IEEE network standards. The Direct-Sequence Spread Spectrum offers highest data speed which of 11 Mbps. In case Of interference, data speed drops to halves.

ITL wireless Equipment

Wireless Access Point Router and Personal Computer Memory card International

  • In a computer Networking Wireless Access Point Router is a Networking hardware device that allows a Wi-Fi compatible device to be connected to a wired network. WAP (wireless access point), in general, connects to the router as a standalone device but sometimes it is an integral part of the router itself.


  • personal Computer Memory Card International Association Cards (PCMCIA) are the hardware interfaces which are slightly bigger in size than your credit card. It enables additional functionality for your laptops and other Wi-Fi compatible

Wireless Access Point

wireless access point router (WAP router) which supports protocol standards including IEEE 802.3 (10BaseT), IEEE 802.3u and IEEE 802.11b (wireless). This device has a built-in router capability and it obtains an IP and uses DHCP. It features 4 built-in port switches. This device is fully configurable through simple web interface.

Broad network categories

Broad network categories There are two broad network categories, 1) Peer-To-Peer(P2P) Networks   -   Peer-To-Peer networks involve two or more  computers pooling individual resources such as disk drives. Each computer acts as both the client and the server, These computers can directly communicate with the other computers. On a peer-to-peer network, for example, a scanner on one computer can be used by any other computer on the network. P2P networks are cheap to set up. Its connection type can be by using Ethernet cable or a Wi-Fi router. 2)  Client-Server Networks -  This involves multiple client networks which are connected to at least a central server on network where, applications are installed.        Clients need access to these server resources, they can access them only from the server. Servers often have private user directories for special users (Example, Windows has Work folders for Special users). Client-server networks tend to have faster access spe

Internet Protocol (IP)

Internet Protocol (IP) An IP address is a unique address used to identify each devices (computer,mobile,printers) connected to an IP Network IPv4 internet protocol version 4 is currently the most used address in standard on the other hand IPv6 is also being used widely.  An IPv4 address contains 32 bit binary number as it is difficult to two people to work with the binary numbers that computer uses IP addresses are converted into decimal format before they are displayed this makes the whole process faster and more reliable - An IP address is a unique address used to identify each device connected to an IP Network.  - 32 bit IPv4 is most widely used while 128 bit why IPv6 is gradually taking over.  - IPv4 uses decimal format and IPv6 uses hexadecimal format. - In networking, IP is a base of networking or CCNA IP Classes The internet protocol or IPv4 system is divided into five classes, Each class is created to accommodate a network of a specific siz
