Cellular network

Cellular network A cellular network or is a means of communication network disseminated more than land areas called cells, every hand round by at least one permanent-location transceiver, called the cell site or base position. In a cellular system, every cell typically uses a dissimilar set of radio occurrence from all their instantaneous relationship to cells to keep away from any intrusion. When attached mutually these cells make available radio exposure more than a extensive geographic region

 Problem of Congestion in Cellular Network Shiva Nageswara Rao Bandereddy (sbandere@hawk.iit.edu) College of Science Department Illinois Institute of Technology, Chicago, USA. Abstract—In the next few years there will be an exponential grow in mobile data traffic due to the tremendous growth in mobile data like audio, video kind of different multimedia application. Cellular network operators invest huge amount to make their infrastructure better like installing new cell tower and offloading data

Radio Network Performance for Indoor Cellular Systems Keshav Kumar Bollu (M547X932) Abstract— Indoor wireless systems with cellular technology provides good coverage and high capacity with great potential if a large number of small radio-ports are connected to a centralized radio network controller. Various radio network solutions are investigated based on this approach. Architecture of a base station sub-system (BSS) is presented and the proposed BSS is based on a distributed architecture.

Summer 15 Nishant Bochare W1165712 Quality of service in Wireless and Cellular Networks A report by Nishant Bochare Santa Clara University Submitted to Dr. Keyvan Moataghed Audience Audience for this topic can be the anyone who has some basic knowledge about networking. This Document provide detailed information about quality of structure (QoS) in wireless networks and cellular networks. This document contain overview of QoS and several enhancement and schemes for

dramatic differences with Cellular Networks (another kind wireless network). The basic difference is Cellular networks have pre constructed structure made of fixed and wired nodes. These fixed and wired nodes are called as base stations. The base stations played a role as access points, and communication between two nodes completely depend on wired backbone and fixed base stations. In a MANET no structure exists, hence these are called structure less networks. In MANETs a network is organized dynamically

The work has been able to verify that the number of mobile cellular network operators who can effectively share infrastructure on a base station is limited by the following parameters: – Sensitivity degradation threshold – E-field threshold or radiation limit – Allowable BTS noise floor limit – Require antenna isolation – Interference level (from spurious emission, leakages, etc.) – Tower wind loading From the result, it was observed that six (6) GSM operators can share infrastructure for a passive

different varieties and classes of UAVs, but none currently offer long range beyond line of sight flight over cellular networks. The only existing networks currently utilized for long-range flight are i-Fi networks. However, flying over Wi-Fi has range limitations that restrict the full use of the UAVs. Therefore, the goal of this project is to design a UAV control system using existing cellular networks as the primary mode for communication. In order to accomplish this objective, an Android OS based application

communication networks. Although Wi-Fi is capable of sending and receiving very large packets of data, it has several physical limitations when used for UAV control. The main limitation is the lack of infrastructure outside of business campuses and test areas. Thus the ability for long distance flights are not easily obtained. A practical solution to this problem is designing a system for UAV control and collision avoidance that is capable of using the existing cellular LTE network infrastructure

there has been a steady climb in developing and enhancing, the mobile phone and its supporting technologies. The cellular network infrastructures as well as service providers have been hard at work; in making sure they are providing the best service as well as devices. The infrastructure alone

wireless scenario consists of homogeneous network and heterogeneous networks. In homogeneous network each base station has similar transmit power level, antenna pattern, receiver noise floor and similar backhaul connectivity. But this type of network has disadvantage of coverage hole. In heterogeneous network the macro BSs is collocated with micro, pico and femto cells. This arrangement increases overall spectral efficiency per unit area (capacity) of the network. Whereas small cell like micro, pico,
