...Technology has shaped the world into what it is today. We have gone from plugging mobile phones into the car, to wireless service over the years. As consumers become more demanding in what they want and need in a wireless network, the more technology evolves through faster service, connectivity, and mobility. 3G and 4G networks are the technology of today, but tomorrow will yield another network much better. 3G and 4G are similar but different when taking the services and applications, their architecture, data throughput, and users perceptions of these networks into consideration when choosing the right network. 3G is the 3rd generation of cellular telecommunications technology that offers broadband services in CDMA, EDGE, EV-DO, and HSDPA, while 4G offers LTE, WiBro, and WiMax (Turbin, 2011. Table 4.1. pg. 97). The Applications a network offers, brings the consumers closer choosing the right network. 3G allows streaming and listening to music, watching movies, playing games, taking better pictures, and video calling. 4G offers the same applications as 3G with additions of its own; Hi Def TV through the cellular service and multiplayer capable games, and downloading social media. The architecture of 3G lies within its Wide Area Cell based circuit switched system, providing voice and data. This means when a user makes a call, its signal is transmitted through a dedicated circuit that can only be used by that call until the session has ended (Turbin, 2011. pg. 94-95.)...

...4G Wireless Network | Compare and Contrast 3G Wireless Networks to 4G Networks 3G networks allow people to have high speed access to data and voice services, they are essentially a high-speed mobile Internet, that can offer speeds of up to 3.1 megabits per second (Mbps) or more. This speed is around the same speeds offered by earlier sellers of cable modems. However, depending on where you are and how many users there are, the actual speed of 3G networks will fluctuate. Even though 3G is still more commonly used, the recently introduced 4G networks have quickly become the standard for wireless communication. The 4G networks are 4-10 times faster than 3G protocols and are ideal for watching streaming videos or movies, and offer more security, unlike a Wi-Fi connection. We can compare and contrast 3G wireless networks and 4G networks in four areas: service and application, network architecture, data throughput and user perceptions. The following standards are typically branded 3G: CDMA2000, UMTS, and EDGE. Whereas 4G wireless is the term used to describe the fourth-generation of wireless service such as WiMax and LTE. Although 4G is a step up from 3G, the limited coverage that is the present 4G market keeps 3G as the frontrunner in wireless protocols being used by the public. While all 4G service is called "4G," the underlying technology is different. Sprint, for example, uses WiMax technology for its 4G network, while Verizon Wireless uses a technology called Long Term...

When individuals shop for services to help keep them connected to the outside world as well as family and friends, the service that is being considered has to be very reliable as well as affordable for the service or services that are being provided. So the quest remains; which network is better and more reliable, 3G or 4G? Throughout this paper there will be a comparison between the 3G network and the 4G network and the many different components that is used to make the networks function. There are many different aspects to the 3G and the 4G network that allow them to be similar in some ways and in different in other. The 3G network service and application offer higher speed that allows users to transfer data at a much faster speed. The 3G network is able to do these things because the network uses software such as CDMA 2000. The CDMA 2000 allow multipath to send signals that arrive in different time delays. Also being used is UMTS is responsible for dealing with high traffic data. This allows users to be able to use a large amount of data without having to deal with loss of connection and spend time waiting for the device finish buffering.

...Assignment 2: 4G Wireless Networks Sierah Nguon Professor Yeates CIS 500 April 29, 2012 Different wireless companies such as Verizon, AT&T, T-Mobile or Sprint always tries hard to convince consumers that their wireless network is the best, the fastest or offers the latest technology for mobile devices. With changing technology, almost everybody has a smart phone which enables them to check their emails or surf the web. Currently, there are two different wireless networks: 3G and 4G. 3G or 3rd generation mobile telecommunication is pretty much an application service that includes wide-area wireless voice telephone, mobile internet access, video calls, and mobile TV, all in a mobile environment. 4G is pretty much the same concept as 3G except it’s ten times faster than 3G. (Lee, 2011). Smartphone users are now consuming more data than ever before on a per-user basis (Kellogg, 2011). With the availability of new apps, services, and cloud storage, users are now utilizing their internet connection more than before (Nguyen, 2012). The current architecture of the 3G network starts with a base station what is referred as a Node B. The radio network controller (RNC) will provide various types of radio-related functionality such as: resource allocation, link layer encryption, and paging and fine-grained location tracking for mobiles in idle mode. It will also provide mobility anchoring for mobiles` data flow as they move from node to node. Meaning...

...Abstract:-The fourth generation of mobile networks will truly turn the current mobile phone networks, in to end to end IP based networks, couple this with the arrival of IPv6, every device in the world will have a unique IP address, which will allow full IP based communications from a mobile device, right to the core of the internet, and back out again. If 4G is implemented correctly, it will truly harmonize global roaming, super high speed connectivity, and transparent end user performance on every mobile communications device in the world. 4G is set to deliver 100mbps to a roaming mobile device globally, and up to 1gbps to a stationary device. With this in mind, it allows for video conferencing, streaming picture perfect video and much more. It won’t be just the phone networks that need to evolve, the increased traffic load on the internet as a whole (imagine having 1 billion 100mb nodes attached to a network over night) will need to expand, with faster backbones and oceanic links requiring major upgrade. 4G won’t happen overnight, it is estimated that it will be implemented by 2012, and if done correctly, should takeoff rather quickly. 4G networks i.e. Next Generation Networks (NGNs) are becoming fast and very cost-effective solutions for those wanting an IP built high-speed data capacities in the mobile network. Some possible standards for the 4G system are 802.20, Wi-MAX (802.16), HSDPA, TDD UMTS, UMTS and future versions of UMTS. The design is that 4G will be based on OFDM (Orthogonal...
