Cis 500 4g Wireless Networks

1. Third & Fourth Generation wireless NetworksThird-generation mobile networks or 3G represents the 3rd generation of mobile telecommunications technology. 3G supersedes 2G technologies and precedes 4G. 3GPP & 3GPP2 The 3rd Generation Partnership Project (3GPP) was formed in 1998 to foster deployment of 3G networks. New generations usually bring new base technologies, more network capacity for more data per user, and the potential for better voice quality, too. 3G networks were a significant improvement over 2G networks, offering higher speeds for data transfer.The third generation of data transmission focused on increased speed by way of sending information more efficiently. A few technological subsets were created, such as W-CDMA (Wideband Code-Division Multiple Access) and HSDPA (High-Speed Downlink Packet Access). The former promised 384 Kbps data transfer speed5 and the latter promised 400 to 700 Kbps. These impressive statistics made the transfer of video and other multimedia possible. With 3G, cell phones are able to access the internet as well as many home computers. 4G stands for the fourth generation of cell phone mobile communications standards, the successor to third generation standards, or 3G. Devices that can tap into a 4G network include smart phones, laptops with a wireless
