function, from radio and television broadcasting, satellite transmission to now ubiquitous mobile phones. Wireless communication has many more advantages as compared to the earlier successful wired communication: These are because of its portability, flexibility, and coverage.
The freedom a hand-held device like a cell phone offers the user is portability. The ability to add/remove device into existing networks without any changes in hardware is flexibility. Technologies such as cellular radio…
Television and the Internet are, in the 21st century, replacing radio. In fact, advances in technology have allowed people to access an increasing amount of information, through different forms. A person wanting to learn about world news can now go on the Internet, read a newspaper, watch television or listen to the radio. The technology behind radio as well as its inventors is the reason why, nowadays, people have an unlimited access to information; it began in 1844, with the invention of the…
measure the effects of RFID technology in a five-layer supply chain management system for the utility sector. While the main objective is to expand, the reader understanding of the possible effects of RFID technology with dealing with supply chain. Radio-frequency identification (RFID) uses electromagnetic fields to mechanically recognize and track tags attached to items. Some believe that RFID is to be well-thought-out the next big thing in supply chain management.…
- Without the sun, we all would be dead, it gives us light, heat and energy to heat up the Earth
- Most of the energy stays inside of the sun because of its gravitational pull, and all small amounts leave the surface in the form of radiant energy

Phones can even cause cancer. Furthermore phones give off radio frequency energy (radio waves). It sends a form of non-ionizing radiation from their battery or antennas. Tissue near it could get cancer and damage your body. Your body can not handle energy like that so it damages your immune system and opens your pores so any type of cancer can get into your body. “It’s looking increasingly likely that cellular phones (mostly…

The lab experiment on Fabrication and Microwave Frequency Measurement of a ring Resonators was about finding the relative dielectric constant and the response of a ring resonator. These values are found by using a ring resonator and setting a frequency signal to the ring to resonate the signal. This lab also shows how to make the ring resonators from paper or any type of electric device from fabrication. Fabrication is used to print electric devices such as printed circuit boards.…
