...4G Fourth-Generation Cellular Communication System AGENDA y y y y y Introduction Evolution of Data Standards WiMAX The Road Ahead Closing Thoughts 4G DEFINITION 4G 3G 2G 1G 0G Fourth Generation Cellular Communication (4G) 4G is not one defined technology or standard, but rather a collection of technologies and protocols aimed at creating fully packet-switched networks optimized for data. 4G networks are projected to provide speeds of 100 Mbps while moving and 1 Gbps while stationary. EVOLUTION OF DATA STANDARDS 4G 3G 2G 1G 0G Zero Generation Mobile Systems (0G) The radio telephone system preceded modern cellular mobile telephony technology (1G). The radio telephone system contained one central antenna tower per region. The central antenna required radio phones to have a powerful transmitter, capable of transmitting up to 50 miles. The number of radio telephones per region was limited by the number of available channels. Unlike closed radio systems, radio telephones were connected to the public telephone network and were typically mounted in cars, trucks, and briefcases. EVOLUTION OF DATA STANDARDS 4G 3G 2G 1G 0G First Generation Cellular Communication (1G) The 1G cellular telephone system divided cities into small cells. This division allowed extensive frequency reuse across a city, allowing millions to use cell phones simultaneously. 1G cell phone technology encompassed analog standards introduced in the 1980s and continued...

... Today, people have those same reactions but, with digital friends they may have never met. You may hear people say they have a few hundred Facebook friends, Twitter followers, or Youtube views of videos they put online. Is interacting with digital friends online considered human interaction? Where does this interaction take place? When you sit behind a computer screen, a tablet, or your Smartphone and update your status or read someone’s updates is it considered human interaction? This author thinks it is not. SMARTPHONE AND NETWORK TECHNOLOGY The first mobile phone call was made in 1973. Martin Cooper, a Motorola engineer called his competitor at AT&T. Although, it took some time after that first mobile call; almost every person has a Smartphone today. Martin Coopers dream has become a reality in that everyone has a mobile phone in their pocket or on their hip. As with the evolution of the mobile phone into a Smartphone so to the network speeds of those systems have evolved. When Martin Cooper made that first mobile call forty-one years ago there were no mobile networks per se. The first network was an analog first generation (1G) that provided speeds of about 14.4K...

This essay will discuss each development of mass media and how it has influenced American culture as we know it. Major Developments of Mass Media in the 20th Century The newspaper happens to be one of the pioneers of mass media. In its early stages the newspaper was handwritten during the 15th century. Newspapers has steadily increased since its earlier days, but a new form of mass media was on the horizon with the introduction of the radio. Radio was first introduced in the “early decades of the 20th century” (pg. 31). This allowed for millions of people to access anything from presidential elections to advertising. The next form of mass media to come was the television. Following the end of World War II the television revolutionized the way we communicated through mass media. With continual enhancements to the television like the VCR and cable television, this allowed individuals the freedom to record and view television whenever and however they wanted. It wasn’t until the creation of the personal computer sometime around the 1960’s that the world witnessed such an enormous breakthrough in mass media.

We cannot deny the fact that we are now more dependent on machines and technology to make our lives easier, especially in this time and age. But one of the most universally-used gadget in this age is the cellular-phones or simply known as cellphones. A cellphone is a portable device whose primary purpose is to make and receive calls for easier and more convenient communication. In today’s time, it’s very hard to find a person who does not own a cellphone. According to Yopie (2011) in her article “Cellphones in our Daily Life”; Cellphones, formerly regarded as a luxury, are now one of the basic needs of our lives. Currently, almost all people carry cellphones, including young children. The mobile phones were barely portable compared to how we see cellphones today. Motorola was the first company to produce a handheld mobile phone, made by Martin Cooper in April 1973. The first ever mobile phone used to make a call was known as a brick phone because of its brick-like shape and size. In 2000, Nokia released their globally-successful Nokia 3310, packaged with more features such as a simple calculator, a stop watch, a reminder function and it also had four games. The 3310 was popular for SMS text messaging because it allowed long messages with 459 characters. In 2007, Steve Jobs introduced the first ever iPhone...

...Communication Providers During the latter half of the 20th century to the early years of the 21st century, cellular phones have become a massive trend in our culture. Cell phones originally were seen as novelties that weren’t necessary and were items that only the wealthy wasted their money on. The majority of people have incorporated cellular phones into their everyday life. From 2006-2010 subscriber numbers increased an estimated 5.9% per year, resulting in increases in industry revenue at an average annualized rate of 3.9% (Brumley). Cell phone would be nothing without a cellular service provider. In order for you and I to have teleconferences, talk with family and friends, or hold any type of conversation while on the go without being tied down by wires cellular service providers offer transmission services to us through radio frequency signals rather than through end-to-end wire communication like land lines. These services can sometimes be complemented with data, messaging, and GPS packages and even more. Due to our constant need to be connected with each other cellular service providers are continuing to grow in the domestic market. For an industry that started less than 30 years ago it had revenues of about $138 billion in 2007 and currently has an estimate of 238.2 million subscribers. Wireless services were based on cellular technology in the beginning. Cellular technology divided geographic regions in cells and sent analog signals to customers using a wave through...
