The Usage Of Cellular And Wi Fi Systems

This paper is organized as follows: Section II will discuss the evolution of mobile wireless networks, Section III will introduce objectives of the 5G mobile network, Section IV will talk about goals to be evaluated in 5G wireless network communications, and Section V will present some concluding remarks.

The increased demand for radio spectrum has resulted from the evolution of feature-rich and high-data-rate wireless applications. The spectrum is limited, and the current radio spectrum regulations make its use less productive. This has necessitated the development of dynamic spectrum allocation policies to make the utilization of the existing spectrum in a better way. As per the current spectrum allocation regulations, specific bands are assigned to particular services and only licensed users are granted access to licensed bands. Cognitive radio (CR) is expected to modernize the way spectrum is allocated. In a CR network, the cognitive radio part allows the unlicensed users (secondary users) to access spectrum bands allocated to the licensed

Define wireless technologies and mobile technologies. Next, determine at least three (3) ways which companies or organizations utilize such technologies to improve business efficiency.

With the advancement of mobile technology, wireless networks have become widely available and interconnected. For allowing people to get connected seamlessly using their mobile devices without being limited by the geographical coverage of their own home networks, roaming services have been deployed, for example, GSM [9], [17], 3GPP [20], and WLANs With the advancements in various mobile and wireless networks, e.g., long-term evolution (LTE) [1] worldwide interoperability for microwave access (WiMAX) [3], and roadside-to-vehicle communication systems [2], pervasive Internet access becomes a reality, enabling mobile subscribers (MSs) to enjoy Internet

Telecommunication technologies have evolved rapidly over the past decades, a situation which led to the arrival of the 4G Long Term Evolution (LTE) to provide faster data speed better than the legacy 3G EVDO data technology. Certainly, LTE has been of great benefit to both individuals and corporations across the globe. However, operators are often faced with challenges such us Capacity constraints, slow throughput due to increased numbers of usage, interference from other wireless equipment, as well as poor coverage issues.

Moreover, the Apple iPhone ought to make its products much more readily available to the consumer. The product will be offered for purchase from the

Wi-Fi (wireless fidelity) is a way to connect to the internet without any wires or cumbersome cables. Wi-Fi technology uses a radio technology called 802.11 b for the wireless connectivity. 802.11 buses 2.4GHz of band frequency spectrum with a bandwidth of 11Mbps(802.11a-5GHz,54Mbps & 802.l1g-2,4GHz,54Mbps).In this paper we have discussed in detail about what Wi-Fi is and How does it work, what the hotspots are and how does the Wi-Fi technology has been implemented in these hotspots.

(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

Abstract: The Broadcast service over is still a system to be commercially employed feasibly.In this paper we discuss how broadcast can be done over LTE-eMBMS and corresponding resource allocation strategies which will allow us to improve our performance. 5G systems are designed to be operational by 2020,we find whether it is feasible to employ LTE-eMBMS from a commercial point of view.

The era of new wireless communication is evolving and it will soon penetrate into daily life and change the way we live. The key concept is integrating the 4g capabilities with all of the existing mobile technology. The purpose of this paper is to provide an overview of different aspects of 4g technology which include its features, proposed architecture and key technological enabler.

In order to minimize the energy consumption at the end device and the usage of the Cellular spectrum should be used only if necessary [17]. We can aggregate Wi-fi and Cellular link Based on the detailed information available for a certain application is possible [18], and can be compared in terms of benefits as well as drawbacks.

This term paper talks of Wi-Fi, the wireless technology that allows internet connection to be broadcasted through radio waves. Its purpose serves directly to the users looking for internet access devoid of any cords or wires.

WiMAX technology has been approved by Bangladesh Government in last quater of 2008 in Bangladesh. Use of this technology has been increased through the passage of time. WiMAX combines the performance of Wi-Fi with the range and quality of service (QOS) of a carrier-grade cellular technology. WiMAX networks can be as small as single base stations with a few subscriber units, to much larger networks with thousands of users. 4G WiMAX gives us incredibly fast wireless access to the internet from four to ten times faster than 3G wireless. WiMAX technology will allow the subscribers to enjoy the amazing experience of high speed internet along with data, voice and video.There are few WiMAX service provider in Bangladesh, among
