Problem Description The 3G network system has been successfully integrated with the varied applications which are required for smartphones. The technology has advanced to an extent which requires enhanced performance as well as capacity. The 4G network system has been introduced for the new technologies such as tablets as well as notebooks for faster accessing the varied information as well as services. There are certain basic differences in between the 3G and 4G network services which are offered to the people worldwide. 3G is considered as the world’s most appropriate and utilized connection service provider for the telecommunication world while 4G is capable to provide ultra speed internet connectivity worldwide (Faisal, “Performance Analysis of 4G Networks”). The technologies which are categorized in 3G are Wideband Code Division Multiple Access (WCDMA), HSPA as well as EV-DO whereas LTE, Ultra Mobile Broadband (UMB) as well as WiMax are considered in 4G. The speed of 4G has exceeded that of 3G and it provides a speed of 100 Mbps to 1 Gbps. 3G is based on the usage of packet switching as well as circuit switching for providing its internet services. 4G is completely based on packet switching for providing its services in an efficient way (Kumaravel, “Comparative Study of 3G and 4G in Mobile Technology”). Therefore, the basic differences are as follows: 3G is the third generation mobile communication standards whereas 4G is the fourth generation mobile communication standards 3G network has been successfully used by users worldwide for great speed as well as performance. The 4G network services provide ultra speed broadband services and it requires to be implemented in an effective way 3G comprises circuit as well as packet switching networks whereas 4G system primarily consists of packet switching network In several segments worldwide the 3G network services have not been fully established for the cost factors involved in spectrum licensing fees. There are many aspects which are to be considered for the effectiveness of the 4G network system such as spectrum allocation, standardization decisions, innovation of technology, processing of signal as well as development of switching methods along with coordination among the vendors providing the facilities. The varied new applications need to have diverse as well as timely different quality of services within the protocol layers in order to support 3G and 4G system. Thus, the newer technologies should be developed in accordance with the type of services it is offering to the people for its effectiveness. The 3G wireless multiple access techniques are totally supported with Code Division Multiple Access (CDMA) as well as WCDMA. The 4G system requires a better multiple access technique for enhanced services as well as performance. The 4G system is required to decrease the Multiple Access Interference (MAI) as well as Inter Symbol Interference (ISI) for enhanced bit error rate performance. Multi-Carrier Code Division Multiple Access (MC-CDMA) is the mixture of Orthogonal Frequency Division Multiplexing (OFDM) as well as CDMA and it is considered to the most effective technique for the 4G system. The framework of 4G is essentially separated into three elements which are terminals, networks and applications (Kumaravel, “Comparative Study of 3G and 4G in Mobile Technology”). There are a few issues which are to be eliminated for the effective performances as well as services provided through 4G system.

In order to improve the mobility, the handover delays as well as packet loss along with loss of communication state should be reduced for efficient performance. All these will help in improving the mobility in Internet Protocol version 6 (IPV6) for establishing a flawless connection of the user to the network (Bandi, “4G Wireless System”). 4G network is capable to provide enhanced multimedia services. The 4G network should be able to adapt the variation of radio conditions for better multimedia services. Furthermore, much variation in the Quality of Service (QoS) of the network may affect the quality of the multimedia services provided. There should be an appropriate framework for encoding the signals transmitted for enhanced multimedia services (Bandi, “4G Wireless System”). These are the a few issues which are required to be minimized for the enhanced performance of 4G networks in providing varied multimedia services. Information Security Model There are certain issues or problems faced by the wireless system and one of the main issues is interference. The interference rises with the use of the same electromagnetic spectrum by many wireless devices. The interference may lead to disruption in the flow of data and may also result in the termination of signal. A wireless network security is the combination of wireless channel security as well as network security which is introduced with the purpose of providing security when connected over the network. The objectives of implementing security model are to ensure that the data or information which is transmitted is secured as well as to ensure that the data is protected from misuse. Furthermore, the security model should also ensure that the security features can be updated as required for protection against new threats (Ahmad, Garrison, Gruen, Kelly and Pankey, “4G Wireless Systems”).
