Abstract
Massive capacity and connectivity are the main boundaries towards standing the Internet of Everything (IoE) basis and defining modern wireless generation requirements. These needs cannot be achieved by already deployed phased array antenna in terms of distributed and oriented geometry, dimensions and design. We propose in the present paper an innovating massive multiple input multiple output (MIMO) spherical array network aiming to draw a new three-dimensional configuration to enhance the beam steering, improve bandwidth, total capacity and the scan flexibility. Resolved issues in concordance with 5G requirements are adaptive massive MIMO by using millimeter-wave antenna arrays, small cell design and definition of recommended operational frequency considering the International Telecommunication Union (ITU) norms and directives. The new geometric forms of spherical smart antenna could easily scan all 3D space, ensure higher capacity and reach tens of Giga bit per second (Gbps) value besides eradicating energy wastage aspect of Beam Division Multiple Access (BDMA) in base stations. Mathematical design is detailed and performed simulation results are presented using MATLAB software Tool.
Highlights
The transported information via mobile networks, counting data, voice and internet are continuously growing with a drastic quality and quantity
Spherical antenna array with Massive multiple input multiple output (MIMO) ensures as a result in dense and vertical buildings agglomerations the coverage quality with the same probability for 3D space
We have modelled mathematically a spherical antenna array with Massive MIMO, which could offer several benefits for migration into 5G mobile in urban zones, when cylindrical array antenna is considered to be functionally limited to direct visibility and not for high buildings cases
Summary
The transported information via mobile networks, counting data, voice and internet are continuously growing with a drastic quality and quantity. In [8] authors propose a 3D spatial channel model controlling, aiming to evaluate practically conceivable boundaries of massive MIMO base stations standardized by the third Generation of mobile networks 3G They consider the Base Stations BSs completely loaded and different configurations of active User Ends UEs per cell besides, they present the established statistical approach to reduce to half the compliance distance in comparison to the traditional technique. Their control chain includes the transmission, under the severe latency and reliability of a short data packet comprising a trivial information payload, over a propagation channel that offers limited frequency diversity and no time diversity They present an achievability bound, built upon the random-coding union bound which trusts on quadrature phase-shift FSK keying modulation and pilotassisted transmission to estimate the diminishing channel, and scaled nearest-neighbor decoding at the receiver. The first section is the introduction, the second section treats the mathematical modelling of the spherical antenna, the third purposes to present performed simulation results and its related discussion and the conclusion and the main perspectives have been done
