The Implementation Of The LTE Networks : Case Analysis

The last best practice evaluated is a new optimization and management services process that monitors, updates and implements third-generation (3G) data services. The article mentions two very important influences in the wireless cellular network industry are "the increasing complexity of wireless network services and the increasing customer demands and competitive pressures upon cellular service providers." (Buvaneswari, Ravishankar, Graybeal, Haner & Rittenhouse, 2004) This new process will not only increase cellular network quality, speed and flexibility but it will also allow these companies to "monitor, diagnose, and optimize their increasingly complex networks." (Buvaneswari, et al., 2004) All five best practices have strengths and weaknesses covered further on in the paper.

In terms of architecture, it has been very challenging to provide platform, and ability to render service with high availability from the providers of the first generation (1G) networks to 4G

The telecommunication industry that AT&T essentially created has undergone radical advancements, particularly within the last decade. According to the IBM Institute for Business Value, approximately 15% of the world’s population had access to a telephone in 1999 but by 2009, 70% of the world’s population had mobile phone subscriptions (Nelson & van den Dam, 2010). Given the extraordinary explosion of mobile computing and wireless communications, continued advancements within the global telecommunication industry are certain. A number of trends drive this evolution including the advancement of devices and network access technology, changes

As one of the world’s largest mobile operators, T-Mobile is growing at a rapid rate. While expanding its 3G and now 4G networks across the world to the UK, T-Mobile is now considered the best data services provider of choice. Customers need to compare the different broadband plans available to help them make an informed decision. By doing this, they need easy broadband access while in the retail stores. The vision for this company is to increase bandwidth speeds for customers. My strategy for this vision is to help improve internet services to customers by migrating, provisioning and configuring the ISP equipment on-site at designated retail store. The steps will include accurately migrating appropriate stores for better services, continuing to monitor circuits after migration is complete for several days and answering questions involving problems with circuits.

Moreover, T-Mobile has successfully strengthened its position as a provider of LTE service with high speed by continuous

While much of the world is connecting their personal devices to fast data sharing 4G mobile networks, on other hand industry pioneers are shaping next generation networks to feed the world’s increasing

As 3G technologies are broader in use when compared to 4G are in limit [2]. The major difference between two is in the existence of yielding technologies. Many technologies EV-DO, HSPA and WCDMA these drop under 3G network. Whereas, many mobile phone companies are intelligent to dup their technologies as 4G; such as WiMax, LTE, and UMB. But, none of these technologies gives detailed description set forth by the 4G network standard, so they are often mentioned as Pre-4G or 3.9G. Here, are the some important points which are compared between two efficient technologies.

Back too 4G/LTE, these two network are the next stage in mobile networking that is suppose to deliver much faster speed than there predecessors. Now some company’s offer 4G only not the LTE, 4G is actually a High Speed Packet Access network known as HSPA. The 4G HSPA offers down speeds between 5 megabits and 8 megabits per second. While 4G LTE is considerably much faster than 4G alone, 4G LTE uses (Multiple Input Multiple Output) MIMO technology. MIMO

In order to maintain the competitiveness of the 3GPP cellular system, Long Term Evolution (LTE), is developed. For downlink transmission the technique selected is Orthogonal frequency division multiple access (OFDMA). In this time and frequency resources are reused in adjacent cells, inter cell interference becomes the crucial limiting factor. This problem can be overcome by using interference mitigation techniques. The

With the development of mobile devices and web applications, people tend to access data, audio, picture and video from their mobile devices anywhere and anytime, thus, wireless mobile telecommunication becomes more and more important. Cellular network technology is the basis for the wireless mobile telecommunication. And the generation is used to describe the development history of wireless mobile telecommunication standard and technology, from first generation (1G) to fifth generation (5G). Fourth generation (4G) is currently widely commercialized around the world by different wireless service providers, or carriers. Mobile WiMAX and Long-Term Evolution (LTE) are two technology categories in 4G systems and the spread spectrum radio technology behind 4G is orthogonal FDMA (OFDMA). 4G not only provides internet speeds that are five times faster than 3G, but also reduces likelihood of losing the connection significantly, solving the problem of unreliability. with sudden drops in speed and complete outages. LTE is based on the GSM/ EDGE and UMTS/ HSPA network technologies, offering high speeds and low latencies over long distances. FDD-LTE and TDD-LTE are two different standards for LTE 4G technology. Besides, LTE Advanced is a major enhancement of the LTE standard, in order to reach and surpass the ITU requirements.

As far as software implementation is concerned, we have to learn the usage of SDR on GNU Radio or MATLAB platform for the successful working of our project. We have to figure out 802.11n protocol variant protocol for its implementation on an SDR in a way that provides viable network performance testing condition. The same has to be done for implementing LTE protocol on an SDR. Testing has to be done to ensure the performance and accuracy of the two protocols on SDR using performance measurement tool kit. Due to the space like environment there will be several propagation constraints that will be analyzed by using EDX wireless software tool. A space communication like environment has to be set up and testing the performance of the two protocols has to be evaluated. The following are the explanations of the various components that will be used in our project and the wireless propagation aspects that will be covered through our project:

(4G) Long Term Evolution (LTE) to provide higher data rates to end users by improving spectral efficiency, deploying more base stations, and/or aggregating more spectra. While some of the LTE enhancements, such as advanced multiple-input multiple-output (MIMO), Coordinated multipoint (CoMP), heterogeneous networks (HetNets), and carrier aggregation (CA), deliver the additional capacity needed to sustain the traffic surge for the next few years, none of them is seen as a viable solution to support the hundreds of times more traffic demands foreseen in 2020 and beyond, the so-called 5G era[5]. However, it is expected that in 5G millions more base stations (BSs) with higher functionality and billions more smart phones and devices with much higher data rates will be connected.[6]. In 5G mobile communication it is expected to have the presence of higher traffic volume, increased indoor or hotspot traffic, and higher energy [7]. The growth of wireless system capacity ever since the invention of the radio right up to the present can be attributed to three main factors: increase in the number of wireless infrastructure nodes, increased use of radio spectrum, and improvement in link efficiency. These three ingredients continue to be the dominant drivers of wireless capacity growth today [8]. As it is

3G and 4G wireless networks can be compared and contrasted by four areas of capabilities: Service and application, network architecture, data throughput and user perception. “Some examples of services offered by 3G wireless networks are CDMA2000 (also known as IMT MultiCarrier (IMTMC), Universal Mobile Telecommunications System (UMTS), and EDGE as well as a long list of others while 4G offer Worldwide Interoperability for Microwave Access (Wimax2) and Long-Term Evolution (LTE- Advance).” (Jamia Yant, 2012, April 26) 3G applications allows users the ability to stream video and audio, video conferencing as well as other multi-media

Because the femtocells will be using a non-dedicated shared (with non-femto traffic) backhaul access technology (such as xDSL), the importance of delivering QoE is greater and more complex than in the macrocell case. Especially in the uplink as many of the fixed broadband technologies use asymmetrical link capacities.

Energy efficiency: Wireless/mobile broadband infrastructures account for more than 50% of the energy consumption of telecommunication operator networks, while the amount of global energy consumption of ICT approaches 4.5% with a rising trend4. It is important that future 5G networks meet requirements
