QoE in Femtocells

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

Assistance with the current macro cell is required to power the small cells and coordinate with internet and radio backhaul and maintaining the Quality of Service (QOS) in the process [1].

Considering that 75 percent of mobile data use comes from streaming videos, Telstra’s wireless LTE roll out would be huge, as reported by the Financial Review. Gigabit LTE would roll out first in the inner metro areas. However, there is no official information yet if mobile internet plans will be updated with the faster speeds. But the fast speed will not be accessible from mobile phones. Which is why Telstra’s move also prompts Netgear to launch the first Gigabit LTE device called the Nighthawk M1 mobile router which will cost $360. This is because current smart phones in the market cannot access Gigabit LTE.

(i) Political: Bureaucracy and corruption may potentially slow down the pace of enhancing the necessary infrastructure for internet accessibility and usage e.g. laying of telephone lines, persistently high cost of computers etc.

The mobile subscribers can use their screen interface without worrying about the amount of RAM or computing power their mobile devices have. It will also help the mobile subscribers to effectively use their battery power and thus contributing towards lower energy bills [8].

It is also believed that the common issues that occur in the LTE network could be reduced drastically if attention if given to certain engineering practices. The research revealed and discussed some of those factors.

For the last thirty years, mobile phones have become a major contributor towards communication, and it has been an essential device to many people. The introduction of car telephones came in the 1980s, and the use of hand-held and hands-free devices has increased quickly.

This article focuses on one of the most used wireless technologies that uses wireless connections of data that avoids expensive process of cables at home: WiMAX. WiMAX stands for Worldwide Interoperability for Microwave Access. Being a faster version of Wi fi, this technology promises speed and large area coverage. It has been successfully proven to deliver the services to the customers (both residential and commercial) economically. WiMAX has the capacity to serve high rates of data that might reach up to 74 Mbps when used a wide spectrum of 20 MHz This has added to its brand value that attracts abound customers. WiMAX falls under the category of MAN technology that came into existence in June 2001. However, the updated version came in 2011 that allowed this technology to provide up to 1 Gbits for particular stations.

A Macrocell user operating in the same band as femtocell users may cause unacceptably high interference levels, if it is close to the femtocell base station supporting the aforementioned femtocell users, and far away from its own macrocell base station. Additionally, the fact that femtocells can be deployed in an ad hoc fashion anywhere within a macrocell, and can be removed as easily, adds to the critical importance of interference management. Notwithstanding the importance of this issue, the concerns listed above renders jointly optimal design of the two networks impractical due to the complexity and overhead associated with a large dynamic network. Consequently, a computationally manageable yet effective interference management strategy is needed. Interference management has been an important design element for multiuser systems in the past two decades. Judicious receiver design for interference limited systems, e.g., CDMA, and multiuser MIMO, proves useful for interference cancellation [3]. In addition to multiuser detection, transmit power control [4], and joint design of transmitters and receivers [5], [6] offer interference mitigation needed in interference limited systems. We note that while our approach does not involve explicit frequency partitioning between the tiers, i.e., relies solely on the space dimensions, allowing for greater flexibility, it is possible to have our scheme accompany a frequency partitioning scheme and increase the number

The overall objective for LTE is to provide an extremely high performance radio-access technology that offers full vehicular speed mobility and that can readily coexist with HSPA and earlier networks. Because of scalable bandwidth, operators will be able to easily migrate from their networks and users from HSPA to LTE over time. LTE assumes a full Internet Protocol (IP) network architecture and is designed to support voice in the packet domain. It incorporates top-of-the-line radio techniques to achieve performance levels beyond what will be practical with CDMA approaches, particularly in larger

Femtocells are fully featured, short range mobile phone base stations used to complement mobile phone services from larger macrocell towers. These range from very compact residential femtocells to larger equipment used inside offices or public spaces. They offer excellent mobile phone coverage and data speeds at all the places. Femtocells have been developed for 3G and also the newer 4G/LTE radio technologies.

Abstract— The ultimate goal of Fiber Wireless (FI-WI) networks is to convergence of various optical and wireless technologies under a single infrastructure in order to take advantage of their complementary features and therefore providing a network capable of supporting bandwidth hungry emerging applications for both fixed and mobile clients. The Fi-Wi architecture is based on radio

The Third Generation Partnership Project (3GPP) Evolved Universal Terrestial Radio Access (E-UTRA) Long Term Evolution (LTE) principles are a piece of 3G advancements. Multi-input,multi –output (MIMO) has turned into a key innovation to enhance communication over a wireless channel. With constrained spectrum, MIMO procedures attain to least target cell spectral proficiency, peak spectral effectiveness and cell edge client spectral efficiency which are the base necessities indicated by the ITU.

Now a day, in telecommunication field lot of antagonism between telecom service providers to provide good quality of broadband services with high speed. In recent year broadband communication

This project report helps to understand the project on SIGNAL BOOSTING USING SMALL CELLS. The main aim of this project is to enhance the signal strength of a carrier network in areas where there will be low network coverage in and around MSU. This can be achieved using small cells which acts as network boosters. Thus, people can make use of this product despite of low network. Each small cell is able to boost signal of a particular carrier, so different small cells are used for different carriers. This project is planned not to work continuously but only when required. If there are events in university, then we can set up the equipment and run the service. For better understanding of the project, it is divided into smaller sections, each section is described clearly, which adds to the overall project. There are specific deliverables for each section which explains in depth about the planning, developing, controlling, and executing of project.
