4G Wireless Networks
Mobile phones have become a crucial part of our daily life nowadays. Everyone, from teenagers to old men, carry a personal cell phone. They are a vital part of today’s on-demand, on-the-go society. Mobile phones today have changed dramatically from the mobile phones of the past. From the huge brick-like mobile phones of 1995 to sleek and stylish smartphones we carry with us now, improved technology has made a great change in the history of mobile phones. As early as the 1980’s with the 1G, or first generation, that was a totally analog service. The nineties stepped up technology with the 2G network and this service was fully digital and the beginnings of wireless data being supported by mobile devices. The two most current used services are 3G and 4G (http://www.electronicsforu.com/EFYLinux/efyhome/cover/jun2003/Mobile-tech.pdf). For average consumers, 3G and 4G are two of the most mysterious terms in the mobile technology dictionary, but they're used relentlessly to sell phones and tablets. Third-generation mobile networks, or 3G, came to the U.S. in 2003. With minimum consistent Internet speeds of 144Kbps, they were supposed to bring "mobile broadband." 4G phones are supposed to be even faster (Segan, 2012). 3G and 4G wireless networks can be compared and contrasted in four areas: service and application, network architecture, data throughput and user perceptions. Some services and applications offered by 3G networks are CDMA2000 and UMTS. CDMA2000 delivers high-bandwidth data and voice services to users of mobile equipment. UMTS delivers high-bandwidth data and voice services to mobile users. UMTS evolved from global systems for mobile communications (http://www.altera.com/end-markets/wireless/cellular/cdma2000/wir-3gcdma2000.html). 4G networks by comparison offer Wimax2 and LTE-Advance. 3G technologies offer...
