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.

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...
