4G Wireless Networks Since 2008, fourth generation (4G) wireless networks have been proclaiming faster speeds for internet connectivity than the third generation (3G) networks. However, upgrading to a 3G or 4G wireless network can be quite expensive. Nevertheless, those who find the need for speed and mobility may find that it is worth the added expense. The war is on between the two generations of networks but there is speculation as to which is truly faster and better. The following paragraphs will provide an overview of both wireless networks, and will include a contrast and compare of 3G wireless networks to 4G networks in relation to application

The IEEE 802.16e design challenges the current 3G technology suppliers based on the orthogonal frequency division multiplexing (OFDM) base technology implemented in 802.16-2004, the 802.16e is devised to provide more sub-frequencies than the ODFDM 256-FFT. Both standards sustain single carrier OFDM 256-fast Fourier transform (FFT) and orthogonal frequency division multiplexing access (OFDMA) 1K-FFT (Wimax Wifi Technology & Broadband Internet, 2011).
Although Sprint’s network provides satisfactory coverage on the east and west coasts it still has problems with connectivity in the middle of the country, and currently there are 12 states with no 4G service whatsoever. If subscribers are unable to attain a 4G connection, they can always fall back to using Sprints 3G networks which is available in all 50 states. Although Sprint states that they will have a national 4G network for now subscribers in the upper Midwestern part of the country will continue to have connectivity issues (WiMAX.com, 2012).
Wireless networks today are primarily the same leading systems used for universal long distance voice communication by using universal mobile telecommunication systems (UMTS) voice-mode, and code division multiple access (CDMA) 2000, which use link accommodated switching and transmission technology. Evolving systems for video circulation, such as MediaFLO in the
