Technology has improved through out the years. Cell phones are one of the everyday technology we use. Cell phones help us stay communicated with our friends and family. Cell Phones are not only use to communicate by calling or a text message it also helps us stay communicated with the rest of the world by using social media. Cell phones can help us in many ways. If you don't know where a place is at you can always use the GPS your phone has. You can also purchase items online, which are much cheaper. You don't have to spend time and gas money on going to stores trying to find what you are looking for. High technology phones can save you gas, money,and time. This is why we want to introduce the new ES Phone. It has unlimited internet and text

Define wireless technologies and mobile technologies. Next, determine at least three (3) ways which companies or organizations utilize such technologies to improve business efficiency.

When Cellular phones first came out the main use was to make phone calls. The first generation of the cell phone transmitted information the same analog format as a fixed line. The second generation (2G) transmission switched to digital which gave cell phones the ability to

With the development of information technology industry rapidly, information system and technology had entered the daily life of thousands upon thousands of families. An information system is used to collect, process, create data and information as a complementary networks now. It can assist a large Internet which supports humans’ activities and decision. It is generally produced consists of six components, hardware, software, data, procedures, people, and feedback. Information systems include that people, processes, machines, DVDs, CDs, telephone, computer, iPhone, TV, iPad and information technology. Information’s produce needs Technology’s support. Technology is a collection of techniques, skills, methods and processes to

The First Generation Networks were referred to as cellular networks, which later termed as cell. The cell phone signals were based on analog signal transmission, where these devices were comparatively less heavy and more cost. The Second Generation phones deploy GSM technology used for mobile communication. GSM (Global System for Mobile Communication) make use of digital modulation to

Cell phones have changed in many ways throughout the years. First, we started with phones that we had to talk with when they were attached to a wall or they would have a line that you could only go so far with them. Then they grew to be able to travel with them, but still only being able to talk on them. They were these big things with an antenna for it to work. As technology kept growing these phones would get more

Information Technology (IT) always being referred to a technology used to make our live better, neither in data processing, communicating, advertising, entertainment nor others. We used IT in our daily live, starting at the very early morning until the very late night. IT has become part and parcel of our live. Nowadays, the hand held device that is one of the most common thing relatable to IT, it is fascinating to understand the benefits and the drawbacks for users.

Over a decade ago the house phone was such a remarkable advancement where it provided a person to call places over thousands of miles away. Then the ease and comfort of wireless phones came out. Now, the invention of cellular phones (a mobile telephone) is an excellent device to do business or call out for help when you need to. While for others it is a failure, annoying and a cause of accidents. “Today, cellular phones have become a necessity in a person’s pocket.”(VanLaecken, H.). In According to the site (http://www.infoplease.com/ipa/A0108074.html), the last survey that was completed contained one million owners in 1999 of cellular telephones. A

The ZigBee technology, has different subdivisions and names and works on the several layers of the OSI model, each having a different name and a distinguished function. This paper focuses on the first two layer of the OSI which is responsible for point-to-point connectivity. The ZigBee technology has an embedded set of features, which can be applied to a wide variety of consumer, commercial and industrial applications. ZigBee builds upon the IEEE 802.15.4 standard, and provides low cost solutions to short distance communications meant mainly for Personal Area Networks. It is in some ways similar to the Bluetooth Technology. This IEEE standard provides characteristics for Low Rate Wireless Personal Area Networks (LR-WPAN). The

This article focuses on one of the most used wireless technologies that uses wireless connections of data that avoids expensive process of cables at home: WiMAX. WiMAX stands for Worldwide Interoperability for Microwave Access. Being a faster version of Wi fi, this technology promises speed and large area coverage. It has been successfully proven to deliver the services to the customers (both residential and commercial) economically. WiMAX has the capacity to serve high rates of data that might reach up to 74 Mbps when used a wide spectrum of 20 MHz This has added to its brand value that attracts abound customers. WiMAX falls under the category of MAN technology that came into existence in June 2001. However, the updated version came in 2011 that allowed this technology to provide up to 1 Gbits for particular stations.

In first generation the radio telephony system is used. At that time a mobile station and a telephone operator are involved in the communication process. First when a person makes call then it goes to the mobile base station and then from there a mobile operator used to connect to the other person based on the request of who has called. Then the call will be connected to the receiver. This long process is done in the 1G systems. This communication is done using radio waves. This technology mainly uses Frequency division multiple access (FDMA). As we communicate through radio channels data is transmitted in

Abstract— The ultimate goal of Fiber Wireless (FI-WI) networks is to convergence of various optical and wireless technologies under a single infrastructure in order to take advantage of their complementary features and therefore providing a network capable of supporting bandwidth hungry emerging applications for both fixed and mobile clients. The Fi-Wi architecture is based on radio

2g systems are commonly refered to as second generation networks and have initiated exponential growth in the number of wireless network from 1990s when digital voice encoding replaced analog systems (1G). Second Generation 2G circuit switched systems are based on various radio technologies including frequency, code and time division multiple access. Examples are 2G systems GSM (Europe), PDC (Japan), and IS-95 (USA). The data links provided by 2G systems are mostly circuit-switched and have transmission speeds of 10-20 kbps uplink and downlink. An overwhelming demand for higher data rates resulted in the introduction of 2.5g which incresed availability and curtailed some challenges such as lack of radio spectrum allocated for 2G.

nowadays sensors are anywhere. We take it for granted, however there are sensors in our cars, in our clever telephones, in factories controlling CO2 emissions, and even inside the ground tracking soil conditions in vineyards. while evidently sensors were around for a while, research on wireless sensor networks (WSNs) commenced returned within the Eighties and it's miles only in view that 2001 that WSNs generated an elevated hobby from commercial and research perspectives. This is due to the supply of less expensive, low powered miniature additives like processors, radios and sensors that have been regularly included on a unmarried chip (system on a chip (SoC)).
