4G Wireless Networks - Research Paper Example In 2001 a new technology was launched in Japan by the name of 3G which stands for third generation telecommunication. In mid 2010 the networks which were widely used for wireless transporters in U.S. were 3G. 3G networks are considered as a noteworthy development over 2G arrangements as they offer high speeds for data transfer. The improved technology offered by 4G over 3G can be compared to the High Definition TV features (diffen.com, 2011). 1. Services and application 3G is the abbreviation for 3rd generation which is a standard defined for wireless technology which allows internet browsing over wireless networks. A good example of 3G technology is EV-DO. Next is the 4G technology which is the generic abbreviation for 4th generation wireless technology which has been optimized for data transfer over wireless networks. This method provides improved speed and efficiency of data delivery. LTE technology is an instance of 4G network compatibility. The 3G and 4G networks comprise of a b road range of cellular data tools. 4G offers speed which is ten times quicker hen 3G networks and it is categorized having downstream range between 20 and 10 Mbps (Nadel, 2010). 2. Network architecture The underlying network architecture of 3G mobile network constitutes of a circuit-switched and packet-switched network. The services which are offered by this technology include wireless voice telephone, mobile TV facility, video calls and mobile internet accessibility. The underlying network architecture embedded in this technology is radio interface which is referred to as â€Å"Wideband CDMA (WCDMA), Code Divisions Multiple Access (CDMA), High Speed Packet Access (HSPA), 2000, GSM (Global System for Mobile), and some referred to as GAN (Generic Access Method)† (Nadel, 2010). 3. Data throughput CDMA2000 is a technology of 3G network which is largely utilized in North America, The data throughput which is offered by this technology is up to 14Mbits/s which has the ability to p rovide additional features like, supplementary outlets, altered inflection and the associated coding techniques, and an aptitude to recover easily from errors. The WCDMA disparate to CDMA utilizes a series of two up to around five channels. The fourth generation networks are outside the range of 3G technology which is designed at higher data rate that falls between 100Mbps to 1Gbps (netlogix.com, 2009). 4. User perceptions If we compare 3G and 4G networks it is clearly apparent that mostly 4G networks have elevated bandwidth which ranges to approximately 100Mbps. 4G networks are able to support multimedia services contrary to 3G networks. The 3G network is designed to include both circuit switched and packet switched networks. If we consider other functions of the system it can be found that 4G has emerged as a more secured and reliable 3G data transmission technology. Moreover 4G networks are recognized in providing international mobility and network scalability which is why it is widely recognized and accepted (Gobjuka, 2010). 2. Distinguish between the 4G LTE, 4G WiMax, and 4G WiBro networks 1. Download and Upload speeds 4G LTE is considered as the current advancement in the range of GSM broadband arrangement. HSPA is defined to provide uplink speeds of 11.5 Mb/s and downlink speeds having 28 Mb/s, while LTE is designed for working with data speeds in the range of downlink speed of 100 Mb/s and uplink
