Importance Of Wireless Communication

1.0 DATA COMMUNICATION

1.1 Protocol

A protocol is typically known as a set of systemized rules that permits a computer to connect and transfer data to another computer. This process is also known as communications protocol. (The Linux Information Project, 2005).

1.2 Bandwidth

Bandwidth is defined by the data transmission capacity of a communication channel. The information that can be carried per unit of time depends on the size of the channel’s bandwidth. It is also referring to the range of frequency that can be carried by a channel. Bandwidth is normally shown in bits per second (bps), kilobits per second (kbps), or megabits per second (mbps) for digital devices and in Hertz (Hz) or cycles per second for analog devices. The amount of

It typically contains tiny glass that carry light beams. Since the data is transmitted via light waves, information can be transferred at a really fast speed and has the fastest data transfer rates compared to other mediums. (Christensson, 2016).

1.8 Wireless Communication

The most common wireless communication is Wi-Fi. Wi-Fi is most likely compatible to a computer that has a wireless card since it transmits to the wireless router. This will then provides Internet access to any devices that is connected to the wireless network. (Christensson, 2006).

1.9 Microwave

Microwave communication is a technique of wirelessly transmission of data. It is related to radio technology. It is a powerful tool that enables data to be transmitted in a long distance without having to use physical wires. It also minimizes installations and maintenance since a microwave signal tower can transmit data across dozens of miles. (DPS Telecom, n.d.).

1.10 Satellites

Satellite communication operates as an overhead wireless repeater station that provides a microwave communication link between two geographically remote sites. It is commonly used in WAN networks, which plays a role as the backbone links to geographically dispersed LAN’s and MAN’s. (Bowla, 2012).

2.0 COMPUTER

Advanced Research Project Agency (ARPA) in 1967. Its initial purpose is to communicate with and share computer resources among users at connected institutions. (Rouse, 2016).

3.2 Packet Switching - a method to deliver data across a computer network connection. The concept was first invented by Paul Baran in the early 1960’s and then was independently developed by Donald Levies, until ARPANET, the world’s first packet switching network is built. (Packet Switching History, 2000).

3.3 Local Area Network (LAN) – Computers connected at a single physical site, however with limited number of networks. The development of LAN allowed the Internet to grow bigger and more widespread.

3.4 Wide Area Network (WAN) – Computers connected between two or more separated sites. The first public WAN was introduced in 1982. However, it was expensive even though it provides faster speed of connection. Nowadays, WAN rises as a popular and affordable option for many people. (Birch, 2016).

3.5 International Network (Internet) – a massive network of networks worldwide. It has become wide accessible by 1990s. It was originated from the ARPANET and has been developed years by years until it becomes a public, cooperative and easily accessible to people worldwide. (Rouse,
