Adair, E, and Peterson, R. (2012). Biological Effects of Radiofrequency- Microwave radiation, IEEE Transactions on microwave theory and techniques, Vol 54 (3) Sources of radiations in the modern world include mobile phones, radar installations, transmission pillars, and microwave heaters. These technological developments have made life faster and convenient. The ability to save time had greatly enhanced human capital capacity to be more productive. Adair and Peterson studied different forms of…

The HC-05 is a serial Bluetooth module for transparent wireless serial communication. It communicates with the microcontroller using serial port [5]. It operates in the 2.4 – 2.485 GHz frequency band The HC-05 has 6 Pins. Table 3.1 Pin description of HC06 Pin Description Key to toggle between data mode and command mode, if set to high, it works as command mode, but default is data mode. RXD Receive data serially (received data will be transmitted wirelessly by Bluetooth module). TXD Transmit…

crucial to understand the limit of certain wireless protocols and how it works in different situations. The most recent Wi-Fi protocol that this report will focus on is, 802.11ac, also known to be the next generation for wireless networks to be equipped with new technologies that could provide faster speeds, capacity, and range. The predecessor, 802.11n, wireless protocol had lower limitation of its full potential to keep the ever growing need of today’s wireless demand. 802.11n lacked the…

system that coordinates immensely high speed wireless communications by using light (Mercer, 2017) It functions by using common Light Emitting Diodes (LED) to facilitate data transfer at speeds up to 224 gigabits per second (Mercer, 2017). Li-Fi proposes a world where common sources of light are able to connect us to the internet. The term Li-Fi was invented by Harold Haas, a University of Edinburgh Professor in 2011. He foresees light bulbs acting as wireless routers and later went on to set…

An area that is more secluded and secure will be more appropriate for Jacket-X to run their business. This will lead to all access points on the Jacket-X network must be safeguarded. Wireless connection will not be open and outsider will not have access to any Ethernet ports or wireless connection. Jacket-X should also be careful when employees following the bring your own device (BYOD) policy to work especially if employees are using the network. Employees can cause substantial damage…

protocol for wireless networks, which includes WEP (wired equivalent privacy). The standards committee for 802.11 left many of the difficult security issues such as key management and a robust authentication mechanism as open problems. The standards they have established have many flaws that have led to a number of practical attacks. With the increase number of wireless technology there is an increase in the range of places people can perform their business. As a result wireless networks or…

Assessments (Or “What do we have of value that must be protected?”) A. The Company Network Figure 1: Existing Company Network 1. Physical Devices a) The NETGEAR MR814 Wireless Router (all versions) has two key vulnerabilities. First, the MR814 only supports Wired Equivalent Privacy (WEP) encryption to secure traffic sent over the wireless network [1]. WEP has numerous, well documented vulnerabilities and exploits. In its standard implementation, WEP can be compromised easily with a…

Process of elimination lets me know that the mesh, bus, etc. could be use, but do not fit the needs of the company. Mesh could be used for the wireless access point that will be put in the student lobby but may not be logical for the entire network. Mesh could be a separate topology from the rest, but for simplistic purposed it was not picked. The bus physical topology does not allow for computers…

1.1.1 Types of Sensor Networks Terrestrial WSNs: - In Terrestrial WSNs, nodes are distributed in a given area either in a pre-planned manner (sensor nodes are placed according to optimal placement, grid placement, 2-d and 3-d placement models) or in an ad hoc manner (sensor nodes are randomly placed in the target area by dropping it from plane). After all battery power is limited and it cannot be reenergized, terrestrial sensor nodes must be provided with a maximum power source such as solar…

Some of the pratical uses of cyber attacks are- fake wireless access points, cookie theft, and file name tricks. Fake wireless access enables hackers to mimic the free wifi of the establishment they are currently in. When users coonect the hacker can then sniff the users computer for unprotected data. With cookies theft hacks gather information…
