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 above diagram shows priori path model of functional impairment, pain, family satisfaction, depression and health-related quality of life (HRQoL). Regarding to the model, it shows that functional impairment, pain and family satisfaction may contribute to depression as well as it may also affect the HRQoL of patients with TBI.

In a study conducted by Karen P. Reed, William Nugent, and Lyle Cooper, the relationships between various components, such as age, gender, substance abuse, depression, and suicide attempts are studied. This study has been published under the name “Children and Youth Services Review” and could be found in volume 55, pages 128-137 of their August 2015 issue. The author’s purpose is to mediate the relationship between biological factors, along with environmental factors, like bullying victimization, and suicide rates and attempts in adolescents.

Affordable mobile communication for civilian and military applications is greatly enhanced by the significant investments in infrastructures such as cellphone towers and repeaters. However, such infrastructures cannot be provided for ad-hoc communication systems and the network connectivity for such systems is greatly degraded by the adverse effects of the communication channel such as multi-path fading, attenuation, non-line-of-sight, etc. As a result, operation at longer wavelengthes (UHF and VHF) is preferred for ground communication between army vehicles to decrease path-loss and bypass obstacles. Also because of the issues related to near-earth wave propagation, vertical polarization is the preferred choice to achieve minimum path-loss.

The idea of the multipath model is a way for mental health professionals to take in the key point information of their analysis of the situation. My analysis of the multipath model is that it’s ingenious because it acts as blue print on finding the specific underlying issues that point to mental health disorder. According to (Sue et al. 2014, p.30) the multipath model is “a model of models that provides an organizational framework for understanding the numerous causes of mental disorders, the complexity of their interacting components, and the need to view disorders from a holistic framework.” The multipath model is important for mental health professionals because it allows a way for them to place individuals within a certain criteria. If we take in to consideration the countless number of mental illnesses that plague society, the multipath model can help us better understand what mental illness individuals are suffering. The multipath model is a excellent stating point to trying to finding an diagnosis. . According to (Sue et al. 2014, p.30) the multipath model is “integrative and interactive. It acknowledges that factors may combine in complex and reciprocal ways so that people exposed to the same factors may not develop the same disorder and that different individuals exposed to different factors may develop similar mental disorders.” As we realize how the multipath model works mental health professionals can better assess the situation and come up with a diagnosis that

The fig.3 and 4 above is a simulated result showing the red is return loss (S11) and blue is insertion loss (S21) obtained for model. Figure 4 shows the reflection and transmission factor measured for the range 1 GHz to 4GHz. This result gives that the bandpass characteristics are valid for a wide range of EM spectrum for communication. In order to get detailed characteristics in the neighborhood of 2.45 GHz, Figure 4 gives more information needed to the measurement results. With the 3 dB boundary, we get about 260 MHz bandwidth, and insertion loss of -4.3 dB, with parametric dimension as given in Table.1.

With the advent of high technological advancements in the field of telecommunication, it has become necessary to provide full capacity network coverage and high data rates to a user at all places. The research paper will focus on introducing small cells as a solution to the user needs by giving an overview of different kinds of architectures for LTE deployment in small cells and coordination techniques for synchronization between these architectures.

The wireless mobile industry is still a growing industry, with revenues continuing to increase over the next few years. Wind Mobile’s unlimited plans have also contributed to the increase per subscriber usage of wireless. Features and functionality redefined by new technology i.e. new

Cell phones operate with radio frequencies, the cell phones use a lot from the waves

Lastly in section (C), path loss exponents are same as that of section (B) but the distance from transmitter and receiver are varied for individual value of path loss exponent. From the graph, it shows us that for n=2, the distance of reduced output power is in the range from 0.1 to 1.5km, similarly for n=3 it is in the range of 1.5 to 2.5 km, and for n=4 it is from 2.5 to

where d_0 is the reference distance and it is usually assumed to be 1 m to 10 m for indoor environment and 10 m to 100 m for outdoor environment, γ is the path loss exponent which depends on the surroundings. The value K is sometimes set to be the free space path loss at distance d_0, which can be calculated as:

In this paper, authors conducted a survey of RF power density in urban environment in order to design a rectenna for harvesting ambient RF energy from free space. Although, RF energy spread out in free space have very low power density levels of 36nW/cm2 at GSM 900 (BTx) and 84nW/cm2 at GSM 1800(BTx) which is a three times the MTx power therefore only power density of base station is considered. By the knowledge of the power available in free

A cellular network is a wireless network distributed over land areas called cells, each served by at least one base station/antenna known as a cell site. In this network each cell uses a different set of frequency so that no neighbor cell can interrupt other’s signal.

4G wireless mobile communication networks are been specified to support display, battery and computational power etc. 4G wireless mobile communication networks should not focus on air interface and data rate, but instead cover advance wireless mobile communication networks and high speed wireless access system into different platforms.

To avoid this situation, a simulation study will be carried on using as parameters: the future in-home data demands with the future femtocell voice and data demands, the different proposed
