Towards an Efficient Radio Network Planning of LTE and Beyond in Densely Populated Urban Areas (original) (raw)

Nominal and Detailed LTE Radio Network Planning considering Future Deployment in Dhaka City

Long Term Evolution (LTE) is the next major step in mobile radio communications and is introduced in 3rd Generation Partnership Project (3GPP) Release 8. It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. With industrial attachment very few radio planning works of LTE are going on. But because of certain commercial issues those works aren"t widely available. Radio network planning is a very vital step for wireless communication technology. As standardization work of LTE is approaching the end line, it is high time to go for efficient radio network planning guideline for LTE. In LTE just like other cellular technologies, initial planning is normally guided by various industries and vendors at their own discretion. They aren"t likely to disclose their advancements and findings. That makes the job even more challenging. As a result, going on with LTE radio network planning perspective is a well-chosen challenge and a certain hot topic in the current research arena. In this work, a detailed LTE radio network planning procedure has been elaborated which concentrates on nominal and detailed planning considering possible network implementation in the densely populated South-Asian city-Dhaka.

Long Term Evolution (LTE) is the latest and most enhanced broadband wireless access (BWA) technology. LTE is the latest standard in the mobile network technology tree that previously realized the GSM/EDGE and UMTS/HSxPA technologies. LTE is expected to ensure 3GPP"s competitive edge over other cellular technologies. The standardization process of LTE is almost at its end.

Network Planning LTE-Advanced

LTE-Advanced is conceptualized to solve the exponential mobile broadband data/voice traffic growth and constant growing mobile subscriber base. It evolved from enhancement of LTE performance to deliver faster mobile broadband. The improvement resulting from the combination of new air interface base technology like Orthogonal Frequency Multiple Access (OFDMA/Single Carrier-OFDMA), higher order modulation, multiple antenna techniques and flexible spectrum utilization has made LTE-Advanced a very attractive technology. A larger bandwidth of between 20-100MHz is expected to be achieved by the use of carrier aggregation concept. The capacity will be further enhanced with advanced MIMO, new features like Relay nodes (interference management) and Femtocell (capacity improvement). The attraction of LTE-Advanced is the backward compatible or integration features that will enable the operators to easily integrate with the existing LTE network. This paper reviewed the enabling technology of LTE-Advanced with the main focus on the planning of LTE-A . It considered planning for both greenfield or virgin network and existing network and also provided all the frequency spectrum of LTE-A both for Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD). A sample network planning based on some key assumptions is also included.

Urban Radio Network Planning for Mobile Phones

La planification de réseaux radio pour la téléphonie mobile en milieu urbain est une nécessite de gros calculs, qu'il est préférable d'exécuter sur plusieurs processeurs en parallèle. D'une part, il faut simuler la propagation des ondes radio afin de pr dire les zones qui peuvent être couvertes. Le programme ParFlow++ a été développé dans ce but. D'autre part, il faut choisir l'ensemble d'antennes qui couvre une ville au meilleur coût. Ce dernier point est un problème d'optimisation combinatoire d'une grande complexité. Nous le traitons avec un algorithme génétique, ainsi nommé pour ses similitudes avec des systèmes biologiques. Urban radio network planning for mobile phones requires costly computation that are better to run on processors in parallel. First, radio wave propagation must be simulated in order to predict the area that can be covered by a Base Transceiver Station (BTS). The ParFlow++ piece of software was developed with this goal. Second, the set of BTSs that cover a city with the lowest cost must be found. The latter task is a hard combinatorial optimization problem, that we try to solve with a bio-inspired genetic algorithm. RADIO NETWORK PLANNING One of the issues telecommunication operators must face when deploying a cellular network in a city is the selection of good locations for Base Transceiver Stations (BTSs). The problem comes down to finding out the best possible sites for BTSs, while guaranteeing that all-or at least a given percentage of the surface of-the streets are covered, and that the global cost of the radio network is kept at a minimum. Assuming that a set of potential sites is available, our goal is to select the best subset of sites capable of satisfying the coverage requirements. The first step, that is, the computation for each BTS of the zone that it can cover, is achieved by a radio wave propagation simulation piece of software called ParFlow++. The second step, that is, the selection of the best BTS sites, is done by a bio-inspired piece of software called Paragene. These two parallel pieces of software are parts of the STORMS 1 project, which aims at the definition, the implementation, and the validation of a software tool to be used for the design and the planning of the future UMTS 2 network.

Practical Introduction to LTE Radio Planning

This paper reviews basics of radio planning for 3GPP LTE. Both coverage-limited and interference-limited scenarios are considered. For the coverage-limited scenario LTE link budget is compared to that of 3GPP Release 8 HSPA+ with 2x2 MIMO. It is shown that, given the same 5MHz bandwidth, both systems have similar cell ranges but, for a given target bit rate, there exists an optimum LTE system bandwidth that maximizes cell range in both uplink and downlink. For the interference-limited scenario (with random uncoordinated interference) we illustrate the relationship between average network load, cell edge target throughput and cell range, as well as the notion of interference margin for cell range dimensioning. Impact of base station antenna configurations on dual-stream Multiple-Input Multiple-Output (MIMO) performance is demonstrated by means of a real-world measurement example. The impact of advanced LTE radio resource management features are briefly reviewed. Finally, the most important radio parameter planning tasks are introduced.
