The vulnerability of 5G telecom deployment cost with increased spectral efficiency, and new heterogeneous dense network deployments offers a big challenge in technology migration from 4G (LTE). Supply chains exist in both Mobile Service Providers (MSP) and Mobile Equipment Providers (MEP), although the complexity of the chain may vary greatly from MSP to MSP and MEP to MEP. In 5G purview, realistic supply chains have multiple end products with shared components, facilities and capacities. In this paper, we explore the effect of migrating legacy 4G MSP deployments into 5G to conform the e-governess needs. SDR applications algorithms from large form factor devices to the smaller one such as handheld mobile devices known as Elasticity Conscious Mobile Service Provider Systems (EConMSP). Our EConMSP framework concentrate on existing MSP infrastructure Volatility, including inherent migration complexity and the implementation. We expose our result for Migration Indictor (MI) in-terms of Device Dependent (DD) or Device Independent (DI) Transformation Steering Factors (TSF), such as Device Reconfiguration factor, Device Interoperability and their relation to inter-MSP or intra-MSPs Volatility. The impact of migration TSF is discussed for diverse mobile multimedia services obtained from standard vendors, OECD, Qualcom, to name a few; at the online website. Migration parameters are optimized against the native MSP services, while switching between different transformation schemes. Our results show that to conform with the 5G e-governess, the MSP infrastructure Volatility can be minimized by using an MSP-centric cost elasticity that enables both the effective use of underlying hardware architectures and the User Equipment (UE) access completely transparent to them. The robustness of our Elasticity Conscious Mobile Service Provider System (EConMSP) framework indicates 5G resource allocation problem in SCM must be decentralized when considering a practical application migration.

The patch antenna is a radiating element which radiates along the walls of edges. The size of the patch antenna reduces by increasing the resonant frequency. The gain and bandwidth of single patch antenna is not sufficient for military applications. For this purpose the patch array antenna is designed. In the present work a square patch antenna design at resonant frequency 5GHz and its array analysis is presented. Array antennas has wide applications in both military, wireless communications. The side lobe levels of linear and planar patch antenna array are -13.5dB. This is not suggestible for tracking the targets. In this present work the side lobe level are decreased in the patch array antenna by introducing the standard amplitude distribution and side lobe level is reduced from -13.5dB to -31.24dB. In this work raised cosine amplitude distribution is used to reduce side lobe level up to -31.24dB.

Antenna is a radiating element which radiates in all directions into space. The antenna is used in wireless communication systems for the transmission and reception .single antenna element is not sufficient to produce required gain and bandwidth. That is the reason why arrays are designed by researchers. Array is nothing but a group of elements arranged in rows (linear) or rows and columns (planar) which provides more gain and bandwidth. In an array system the main beam width is reduced by increasing number of elements, hence the gain and directivity is increased. The side lobe level of a linear array is -13.5 dB which is most advisable for point to point communication. In the present work by using standard amplitude distribution is used to reduce the side lobe level is reduced up to -22.0 dB and which is compared with the uniform linear array. Plots are drawn for small and large arrays from N=10, 20and 40. In the present work the practical element arrays are designed for small and large arrays .the results are compared with the ideal arrays which came with good agreement. The practical element used in the present work is waveguide. The standard rectangular waveguide are used in this work to produce narrow beams and high gain, by neglecting inter element interference the designed wave guide arrays for N=10,20,40 by adopting standard amplitude distribution to these arrays side lobe level are also reduced and are compared with the isotropic arrays. The results come up with good agreement.
