How Technology Can Replace The Existing Wireless Technologies

This paper gives a clear understanding on the current state of art on the IoT. The primary idea of the IoT concept is the pervasive existence around us of a wide range of things such as Radio-Frequency Identification (RFID) tags, actuators, sensors, mobile phones, etc. These are able to communicate with each other and collaborate with their neighbors to reach collective goals through distinctive addressing scheme.

Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

The world is getting smarter and better and so are the devices. With the improved technology, we can check our mails on our watch; control our home temperature through our smartphone and much more. The term Internet of Things is referred to any object or device which connects to the Internet to automatically send and/or receive data [1].

This report fulfills the specific requirement for documentation as specified in FIT 5083 Assignment 1. In this technical report, we will identify the various steps and techniques used in deployment of wireless network. Initially, what is networking or network infrastructure? Networking mean to connect two or more devices and configure them in such a way that they can communicate with each other. In networking, network infrastructure means to connect the software and hardware part rather than actual connection between two devices. Now days, wireless network connections are highly on demand because it’s easy to access and it does not require any cabling structure.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

802.11ac is a fifth generation WLAN standard. The transfer speed of this standard is three times higher than the speed of its predecessor and is at the same time much faster than the standard that emerged in 1997. Its security is improved, and both the capacity and the range of this standard are significantly enlarged. Those features play a key role in its quality improvement. Its speed reaches up to 1Gbps, enabling high bandwidth transfer on multiple devices at the same time. The 5GHz channel reduces the number of errors. There is large number of wireless devices that broadcast equivalent omnidirectional signals but when using the 802.11ac standard there is an option to find the location of the broadcasting device in the network. Using this option, the sender can locate and send the packages directly to the device which is connected to the Internet and that is the reason why the signal is stronger, clearer and three times faster. The aim of this research would be to analyze all characteristics mentioned above and their practical implementation in a device that uses 802.11ac standard.

In order to establish a given area network, wireless communication means is used by wearable devices to transmit data to proximate devices. Data transmission must be secure since wearable devices transmit vital information. Wearable wireless communication system is exciting new frontier techniques. There are many devices worked in

Wireless is a technology that transmits signal without using cables as the medium to communicate from one end to other(s) end. Communications via wireless can be anything from radio broadcasting, SOS signal from a ship at sea, or day-to-day Wi-Fi that we use to connect to the Internet. Actually wireless technology is a technology that already been in development for quite a long time, it developments already begun since late 19th century. Here is the timeline of the development of wireless technology:

Focusing onto the WLAN Notions and Constituents, we already have got the basic idea on the wireless devices. Ranging from notebooks to smart phones, each and every device has got an in-built wireless card slot. It enables the gadget to be able to operate on a WLAN wiring consideration. In certain instances, enterprises and organizations are set up in search a way that the host is not directly attached to the device being used (Janevski, 2003). It is often stationed at a particular place in the office and from it, data can be transmitted to

IEEE 802.11 commonly known as Wi-Fi is a set of media access control and physical layer specifications for implementing wireless local area network computer communication in various frequency bands such as 2, 3, 3.6, 5 and 60 GHz.

Wireless network is indicated to a telecommunication network whose interconnections between nodes are implemented without the use of wires, such a computer network. Nowadays, wireless network has become the important thing in telecommunication. This sort of technology has been used for over a century and remains synonymous with radio. In 19th century, Guglielmo Marconi invented a radio and made his made his mark in the world of wireless technology.

-WPANS: Wireless Personal Area Networks: The two current technologies for wireless personal area networks are Infra Red (IR) and Bluetooth (IEEE 802.15). These will allow the connectivity of personal devices within an area of about 30 feet. However, IR requires a direct line of site and the range is less.

Consumer grade equipment that is used in most home network installations, is manufactured to support fairly small environments. Small environments are networks with about five to ten devices connected at the most, at one time. Enterprise grade equipment is created to support large corporate networks with large amounts on users. In the past, corporate wireless networks used multiple access points to ensure continuous connectivity. Today, wireless networking has evolved to enable the use of wireless controllers. Wireless controllers connect access points by using the same SSID and channel for each, which enables uninterrupted connectivity. The wireless controller is the wireless gateway. Corporate networks are established in a similar but more complex architecture as home networks. Networks utilizing a wireless controller base their infrastructure off of a hub and spoke or distributed mesh setup.

He is a German Professor of ‘Mobile Communication’ at University of Edinburgh, Scotland. He explained that in future a new standard of communication is required for wireless communication as current and most widely used standard Wi-Fi has some inescapable disadvantages. The term Li-Fi was also coined by him and is capable of overcoming some major bottlenecks of Wi-Fi like radio interference, bandwidth, security etc.
