There's no doubt: the most important part of any mobile or fixed network are its Configuration Parameters. Making an analogy (comparing) of a network with the human body they would be the brain.
Of course, in the human body all the organs are important. However, some have more importance, and other less - on a scale, the brain would be the first in the list.
And in a network it is no different. There are several mechanisms of management or control, but the most important (as we shall see... read more

If you work with telecommunications, it is very likely that already has come across the following request: generate a map in Google Earth (kml file) from a table with latitude, longitude and some other basic information.
This task may seem simple, but if you've tried to do it, probably realized that it is not as easy as it sounds!
Many people don't even know where to start: ask for a friend to help, do a good 'Google Search', among other efforts.
What happens is that as this... read more

The reach area of each cell of the network directly affects the efficiency of the system in terms of Quality, Capacity and Coverage.
Therefore it is essential that each one be perfectly adjusted. These adjustments include changes to the configuration parameters (eg, for load balancing), and also adjustment of physical parameters.
In the latter case, the adjustment of tilts and azimuths (and sometimes height) of the antennas is a key factor in achieving the best possible results.
The... read more

Hello friends, today we will talk about a small change in our presentation way, or the methodology of Hunter tutorials, mainly due to user requests.
Until today, all tutorials were written so extensively, aiming mainly to allow an easy understanding of everything that was needed so that all users could learn how to use their own tools available, such as Microsoft Access and Google Earth.
To do this, in several tutorials, we extensively detailed the use of Access and VBA, demonstrating how ... read more

When you need to access a specific FTP server and download or upload one or more files, the best option is to use the standard FTP programs, like the one we recommend: Filezilla.
However, when this task has become repetitive, as when we download daily files from multiple OSS (via FTP), then it's better to automate it - less wasted time, minimize errors, etc..
And a way to automate the execution of FTP is to create a Windows application that performs the work.
Let's ... read more

The conversion of Coordinates to Addresses is an issue that arouses interest from many areas, not just Telecom.
And one reason is that this mapping is increasingly present in our day-to-day, for example when we receive a list of Addresses, and we need to make such a coverage analysis at each point.
There are several ways to obtain this conversion from a manual to fully automated type. But when we don't have a standard procedure to obtain these data, we ended up... read more

Microsoft Office Excel without any doubt is one of the most used program when we need to do Data Presentations such as charts and graphs.
When Data are showed in tables, a feature also commonly used are the filters, to limit the records of the table based on certain criteria.
The Excel Filter options are already good, but we can always do a little better, especially in the issue of improving the the user experience and interactivity.
For example: we can quickly ... read more

Frequency Planning and Neighbor List Verification are two major tasks required to ensure an efficiently Optimized Network.
This analysis can be done in several ways, and one of them is by checking geo-referenced plots, where possible problems of 'Interference' or 'Missing Neighbors' can be easily identified.
Google Earth is a good place for this type of inspection, but Mapinfo also has its advantages - especially in terms of interactivity (eg it is easier to create an ... read more

One of the most important tasks for an efficient control of a cellular network is to ensure that all of its Configuration Parameters (GSM, UMTS, LTE ...) are properly adjusted.
Any one parameter, incorrectly configured can cause real damage to the Performance, and therefore to Customer Satisfaction. And the time it takes to find such a problem is unnecessary - since the problem could be easily and quickly found by an efficient and automatic algorithm.
The causes for... read more

One of the keys to the success of all activities of the Network is to collect all information of the configuration parameters (GSM, UMTS, LTE ...) on a single and updated database.
From this base (parameters database) we can accomplish a lot of actions, with benefits of several types: audit parameters, accurate reporting, plotting to Google Earth and Mapinfo, updating other databases and other tools such as drive test etc..
If you're reading this tutorial, you... read more

Let's talk today about organization, especially the documentation of sites in a cellular network. Quite simply, let's see how this information can work to our advantage.
We like and agree with a famous phrase used in IT: "Every non-hierarchical structure tends to become obsolete."
But what does this have to do with me? Let's talk a little more about it, and then you decide for yourself whether the suggested practices apply to you, or you can help.
So here we... read more

At first glance, this is a subject that seems to be not so important, or at least not have much relationship with Telecom and IT.
But then answer the following question: "If your boss asks you to do a draft, an outline of the installation of a site on the rooftop of a building, how would you get it? What are the minimum information that such a design should contain?"
So, even if it seems a simple matter, it's worth talking a little about it. Even if only to remind... read more

When we talk about or KPI in Performance Analysis, what immediately comes to mind? While the answer to this question is particular to each person, we can think of a general answer in a report: a table, chart, map or even a combination of all.
No matter what the format of this report is, it is correct to state that it serves to tell us a comparison of indicators. This comparison may be on a fixed value, or on a different magnitude, among others. These are the 'algorithms' ... read more

We've already learned some applications using System Hunter, mainly using VBA and Access and Excel. Except that until now, we need to run any of it - for example Hunter GE Network, which plots the network information sectors in Google Earth - we neede to use methods not so friendly, like running macros directly in the program interface or the VBE environment.
But when we talk about applications, the first thing that comes to mind is an interface, does not it? Okay, the... read more

Hello! If you are following all the tutorials, you've seen that we can represent our network through geo-referencing tools such as Mapinfo and Google Earth, and also that with this kind of tools we can perform tasks such as analysis of drive tests. But there are other important ways to evaluate a network, one, probably the main one, is through the analysis of statistics, and this is what we'll start seeing today.
Start? Yes, start, because the analysis of statistics is a ... read more

The representation of sectors across our network of lines as we have seen is sufficient for several tests. However, it is sometimes more interesting to work with symbols instead of simple lines, such as the sector represented by a symbol like a rose petal. Today we will create our first program Mapbasic - where we'll see how this is done.

In the previous tutorial, we had our first contact with Mapinfo and Mapbasic. We had a brief introduction to Mapinfo, and also how to use Mapbasic - your programming language without having Mapbasic installed. Although soon we will see a series of programs Mapbasic, today we will take the opportunity and not let us use the Mapbasic itself, through the interface of your program. Alternatively, we learn a new concept that can be learned and that we also use a lot, not only with the MapInfo:... read more
