4G Wireless Networks - Research Paper Example

? [4G Wireless Networks] Compare and contrast 3G wireless networks to 4G networks Cellular data networks often referred to cellular generation is an advancement of cellular communication. This advancement includes 1G, 2G, 3G and 4G network communication protocols. The most recent version which is referred to 4G provides higher speed and faster communication as compared to 3G networks. The international standards recognized for mobile communication are regarded as 3G and 4G. The standards are used for specifying how the airwaves are utilized for broadcasting information which includes voice and data. 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 broad 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 “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 provide 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 speed of 50 Mb/s. In this scenario, WiMAX is derived from a Wi-Fi technology. Wibro is designed to provide data 30 Mbits to 50 Mbits per carrier while the area which can be covered by wimax is 70 kilometers along 4km radius (Krendzel, 2012). 2. User perceptions Considering the underlying technological concepts, WiMAX and LTE are extremely comparable, with most important divergence present in communication speed and the structure of this network which is designed to have operability within the network. LTE is considers quicker, but WiMAX offers ubiquity. WiBro is a new wireless technology which is designed to provide facility to users for watching TV on their cell phones. 4G networks are considered superior, and much better as compared to the third generation networks, on their on their differentiation. The new technology has many features to offer that 3G could not attain. However it is considered as an development of the previous version of telecommunication they are not being utilized extensively as prior technologies (goingwimax.com, 2009). 3. Backward compatibility The backward compatibility of LTE is designed with GSM and HSPA. The restructured WiMAX criterion of 802.16e is regarded as “Mobile WiMAX” which is backward compatible with the prior versions of WiMAX standards. The term which is coined for the earlier versions is “fixed WiMAX.” In addition, both WiMAX and LTE are able to afford elevated spectral competence, advanced signal competence, and condensed signal latency. Fixed WiMAX is designed to provide speediness of up to 75 Mb/s and Mobile WiMAX offers speeds of up to 30 Mb/s (freewimaxinfo.com, 2012). 4. Service availability Wibro technology has been implemented for achieving TDD for duplexing. WiBro was designed for defeating the data rate limitations of cell phones as CDMA. WiBro wireless technology is currently in the developmental process and when it is fully improvised it will be introduced with new standard on the whole with an ultimately different name. Wibro network expertise is comparable to Wimax the communication speed but both technologies are similar. In addition, WiBro design provides high speed which is up to 74MPH while Wimax provides connectivity over 31 miles. Possibly due to its novelty and high operation cost the current generations are seems to be moving towards 4G network technologies (Wurdeman, 2012). 3. Identify why the competition between the 4G LTE carriers has been so fierce and describe the benefits of this competition to the subscribers. The fourth generation 4G network of wireless communication is regarded as the best in having higher speed for internet connectivity as compared to the third generation (3G) networks. On the other hand, upgrading to a 3G or 4G wireless network can considered moderately expensive. It is evident that regardless of all the challenges faced the 4G LTE technology is catching fire among rural U.S. carriers References diffen.com. (2011). 3G vs 4G.
