Advantage And Disadvantage Of Mobile Communication

know that the tag responded and hence be able to track the tag. Hence, secure search protocols

The first cell phone was created by Martin Cooper on April 3rd, 1973. Cell phones are radio receivers and transmitters that use electromagnetic energy to send and receive information. Energy travels in waves. The distance from one wave to the next is the wavelength. Frequency is the amount of times the wave oscillates up and down per second. The higher the frequency, the more energy. Frequency is measured in Hertz. One Hz is one wavelength per second. Different electronical things are operated at different rates of hertz. At this point, the fastest connection runs at a 2.1 GHz (gigahertz) range-- that’s 2.1 billion wavelengths per second. Cell phones use low radiation called radio frequency (RF). A cell phone sends and receives

It also helps you to search the nearby restaurants, hotels and gas stations and is very useful for a new place.

-Texting is another good way to reduce the radio frequency radiation because your phone is not close to your

Check with each cell phone carrier about coverage areas and reception. With some carriers, you have better coverage over a larger area than others.

another cell phone. Once one of the RF channel is modulated one of the radio signals are then

The mobile technology has changed the world around us tremendously and it continues to evolve at a very fast speed. Today, we can buy almost anything from our cell phone device, from clothes to groceries; perform transactions between bank accounts, or even check –in for our flight.

An RFID system may consist of several components: tags, tag readers, tag programming stations, circulation readers, sorting equipment, and tag inventory wands. Security can be handled in two ways. Security gates can query the ILS to determine its security status or the tag may contain a security bit which would be turned on and off by circulation or self-check reader stations.

RFID tags are much more efficient than simple barcodes because of a few key features. Unlike barcodes, RFID tags do not need to be on the surface of the object. This means that the tag does not need to be subject to the elements. RFID tags can also be read much more quickly than barcodes. Where barcodes need to have a device pointed directly at them to scan them, RFID tag readers need only be within range of the transmitting signal. This allows scanning process to be much more automated. Finally, RFID tags can be read almost simultaneously (mostly due to the high speed reading and use of different wave lengths) (What is RFID, n.d.).

he current market for UAV control software lacks flexibility for long range flights with collision avoidance capabilities. There is currently no consumer available option for BVLOS besides wide range Wi-Fi

The Global Positioning System (GPS) is a very simple to use but very complex in terms of how it works. The Global Positioning System relies on a network of 24 satellites approximately 20200 kilometres above Earth in space, orbiting on 6 different routes (four satellites each route). These satellites will orbit the twice in the time frame of only 24 hours. The Global Positioning System Satellites work by transmitting 2 radio signals also known as L1 and L2 to the Global Positioning System, the L1 signal consists of a frequency of 1575.42MHz and the L2 signal with a frequency of 1227.60MHz. These signals are sent once a Global Positioning System is within the line-of-sight connection with at least 3 satellites. Once in the light-of-sight, the satellites broadcast radio wave signals towards the Global Positioning System that carry information of location and time. Once these signals are sent, a special type of equipment called a Global Positioning System receiver receives them and decodes the information carried. The Global Positioning System can be used for numerous jobs such as navigation for cars, ships and aeroplanes, various military jobs, measuring large landscapes and measuring changes in water levels. With the application of Global Positioning Systems for navigation the risk for road, air and water collisions has been greatly reduced due to the Global Positioning System giving guidance to driver, pilots and ship captains uncertain of their location. Along with the

Humans throughout the ages have used maps to help them travel. As we enter the modern age, maps on the internet and global positioning system(GPS) have become a more efficient way to travel because it allows users to get a step by step instruction on how to get to their destination. In 2004, Google debuted Google Maps, a service that that disrupt the GPS device industry and has paved the way for future navigation and GPS related apps. The success of Google Maps was primarily based on the advances of technology, economic events, its versatility, and how it is practically free to use.

Mobile technology gives people the power to build community and bring the world closer together, as we can connect our loved ones far and near. Regardless of where one resides, communication and strong community can be possible with the help of mobile technology. When I came to the United States back in 2012, I was homesick. There was not a lot that I could do to connect with my friends and relatives back home, other than send them texts or call them. Now, with more advanced technology that I am exposed to, I can video call on Facebook Messenger. I have been video calling my friends and relatives back home since 2013. Although we are living different lives, with the help of the Facebook Messenger, we are able to share our experience with one another. I am used to this feature, and I cannot imagine myself losing touch with my friends and relatives back home, as I learn from their experiences just as I tell them about mine. The reason I have not gone back home since 2012, is because of Facebook’s video calling feature. I did not feel a need to go see my friends and relatives because I was able to see them through video calling. When I video call, I am usually with my friends. That way I am able to connect my Indian friends with my American friends and form community between the two.

The domain chosen for this project is technology. I chose this field because of my strong passion and interest for innovative technology. This report will involve various datasets such as Statistics analysis of science, technology and industry, Innovation statistics and indicators, Key biotechnology indicators among others. The questions that I plan to answer in this analysis are:

As most technologies are started from some sort of military operations, the Global Positioning System (GPS) was used for tracking troop locations and evolved to precision-guided bomb and missile attacks. Today, the use of GPS has converted into everyday use by the average person.
