Chapter 7, Problem 4RQ

Explanation of Solution

Bluetooth

• Bluetooth devices are used to transmit low power wireless data with devices in small range distance at the range of 10cm (Centimeter) to 30m (Meter).
• Bluetooth devices contains higher transfer rate at the range of 722 kbps (Kilobits per second).
• It is low-cost and easy to install, simple and convenient to use, and many applications can be transmitted using the device.
• The Bluetooth is used to transmit between music players such as mobile phones to headsets.
• It will connect one computer with another computer.

Wi-Fi (Wireless Fidelity):

• It has third generation wireless access connection. In this, the data is transmitted to or from the node points within the radius range.
• The radius of the network ranges up to meters. The node point is connected to a wired network and shares the data with wireless users.
• It is connected through Local Area Network (LANs), and Wide Area Network (WANs).

WiMAX:

WiMAX stands for Worldwide Interoperability for Microwave Access.

• WiMAX is the forthcoming new technology standard for long distance wireless communications.
• The WiMAX technology is designed to join the Wi-Fi and DSL (Digital Subscriber Line)...

Explanation of Solution

Capabilities and suitable applications of each types of technologies:

Bluetooth – it provides only limited access; it is used to create small personal-area network.

Wi-Fi – it covers from 30 meters to 50 meters; it is used to create small local-area network...

Explanation of Solution

Radio Frequency Identification (RFID):

• RFID is a mobile wireless technology that is used to facilitate supply chain management.
• Movement of data is tracked by RFID. It capture and provide instant goods movement information between the supply chain partners.

Working of RFID:

• RFID system provides a microchip that contains the details of an item and its location...

Explanation of Solution

Wireless Sensor Data (WSN):

It is a network of organized wireless devices. A network consists of thousands of nodes.

It helps to observe the building security or to detect harmful substances in the air.

Working of WSN:

• The WSN are networks of interrelated wireless devices with some processing and radio-transmitting capacity that are embedded into the physical environment to give measurements of various points over huge spaces...
