During the last several years, there has been a tremendous increase in the usage of mobile communication systems for data transfer, generally by means of web based data or voice data. This expansion is related to the go up in the number of cellular devices, particularly smartphones, and a rise in the number of web-based services, for instance, banking, video streaming, cloud computing and so on. According to the past data figures from Cicso , globe mobile data demand grew about 2.5-fold on a yearly basis at the time of 2008 to 2011, together with may be mobile-connected items, which include smart phone, netbook, is usually projected to remain across. 7.1 billion in 2015 and As per the latest measurements from Cicso  that the worldwide mobile video would be the three-fourth of the aggregate mobile data traffic by 2020. To meet this increasing data-demand of a growing number of users, better communication systems need to be designed for future mobile generation (5G). However, this proposal will concentrate on one...

...and grounds the Pilot Pollution Interference (PPI) problem, however, this PPI problem, identify for the 5G and will make the solution is the other key goals of this proposal.
Rapidly increasing the user demand will cause load balancing problems for future generation (5G) and therefore the future generation will affect by queuing delay. So, this solution will make to investigate is the other strong objective for this proposal.
2.3 Research Questions
1) How heterogeneous network deployment based on micro, pico and femtocells can be used to build a ?green? cellular network?
2) Why Interference problem is one of the most important challenges for 5G, how this problem have solved for 3G and 4G?
3) Why Load balancing technique is very important for the massive differences in the coverage areas with different cells and possible solution to overcome this problem?

- Introduction Wireless communication has improved dramatically in the last few years. Their networks are indispensable providing the means for mobility, city-wide Internet connectivity, distributed sensing and outdoor computing . It allows the transfer of messages between people that are on the other side of the world. Without wireless communications people would not have a lot of the devices many 21st century citizens could not live without, namely the smartphone. It is also required for devices using Bluetooth, remote controls, Wi-Fi; really any electrical devices that communicate via a wireless or wired channel ....

- The future wireless communication systems (sometimes said to be 4G systems) are required to support various multimedia services such as speech, audio, video, image and data at much higher data transmission rates. With the multiple users on a system, resources need to be shares between among the users in order to establish a communication links between the mobile user and base station (BS). However, the available resources are often limited, as the total bandwidth of system is limited or restricted.... [tags: Mobile phone, GSM, Cellular network, Radio]

- In the early days of the mobile phone, AT&T and Bell Systems was no doubt a first mover which is a technology company that competes with other high tech companies to develop innovative products and services according to Hill, Jones, and Schilling (2014). The company’s actual first mobile call took place on June 17, 1946, and was made from an automobile in St. Louis, Missouri. There was a first mover advantage for AT&T which offered an innovative idea, mobile telephone service, when there was no similar service being offered for the general public of its kind out on the open market....

- Mobile Application were designed to be used on smart phones, tablets and any other hand held devices. Mobile Applications have become such a viral thing in today’s century. Mobile Communication has integrated so much in our lives we almost feel incomplete if we were to leave our cell phones at home. When mobile apps were first created it were just the basic applications on your software such as, calculator, calendar and clock. The first cell phone manufactured was the Motorola Brick this phone was just a simple operating system whereas it was only use for calling and the only application was the contact list....

- ... It uses persistence scheme such as weighted p persistence, slotted 1and p persistence. in well connected neighbourhood. In sparsely connected neighbourhood, vehicles can instantly rebroadcast the message with vehicles travelling in the same direction. If the network is totally disconnected, vehicles use the method of store and broadcast message till another vehicle enters into communication range. Advantage: DV-CAST can handle both the broadcast storm or disconnected network problem Disadvantage: DV-CAST has many design parameters that need to be tuned properly in order to optimize the performance....

- ABSTRACT Long queues are experienced in retail stores as customers have to form a line at the checkout stand to make payment for merchandise purchased. High costs of operations are thus experienced due to the large number of employees needed to ensure smooth running of the business enterprise as a minimum of two employees are required on each counter to facilitate scanning, receiving payment and packing of the purchased goods. This research work seeks to address this problem by proposing a mobile self-checkout system using a combination of barcode scanning technology, mobile money integration and card swiping technology....

- The History of Mobile Communications (Aundrea) The history of mobile communications has made a huge impact on how we live our lives on a day to day basis. Who would have thought that a small piece of equipment, had great influences in our society and the world. This all began in the 1940 's, when Bell Laboratories introduced the United States and Canada to the idea of cellular technology. One of the largest communication companies, Motorola was the first company to embark on this technology.... [tags: Mobile phone, Text messaging, Cellular network]

- Mobile devices have had a short history of only forty years, but the large technological advancements that we have access to today have started to take over the scene and will continue to do so as long as technology becomes more accessible and more functional. In the very beginning of mobile phones they were largely inconvenient and extremely pricey, and though they were open to all consumers, only the wealthy could afford to own one. A driver in St. Louis Missouri made the first mobile phone call in 1946, and it was made possible by an AT&T team that worked for more than a decade to make possible....

- 2.1 Handheld Mobile Devices and Mobile Applications 2.1.1 Defining Handheld Mobile Devices The medium for mobile applications is a mobile device. While the functions of mobile devices vary, the key criteria such a device must fulfil is portability. To that extent, mobile devices have been described as ‘interactive wireless media’ (Haghirian and Madlberger 2005, 2). Mobile devices offer a range of capabilities, but essentially they allow access to data and information with the opportunity of being used in a variety of environments (ISACA 2010, 2)....
