The Evolution Of Mobile Communication System
![Page 14: Mask Lte Planning Tool](https://reader035.vdocument.in/reader035/viewer/2022081418/5578a68dd8b42a4d4b8b4704/html5/thumbnails/14.jpg)
The Evolution Of Mobile
Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires”. The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications).The 0th Generation Technology (0G – 0.5G) The great ancestor is the mobile telephone service that became available just after World War II. In those pre-cell days, you had a mobile operator to set up the calls and there were only a handful of channels available. 0G refers to pre-cell phone mobile telephony technology, such as radio telephones that some had in cars before the advent of cell phones.
Technologies used in 0G systems: 1- PTT (Push to Talk). 2- MTS (Mobile Telephone System). 3-IMTS (Improved Mobile Telephone Service). 4-AMTS (Advanced Mobile Telephone System). 5- OLT (Norwegian for Offentlig Landmobil Telefoni, Public Land Mobile Telephony). 6- MTD (Swedish abbreviation for Mobil Telefoni system D, or Mobile telephony system D).
![Page 15: Mask Lte Planning Tool](https://reader035.vdocument.in/reader035/viewer/2022081418/5578a68dd8b42a4d4b8b4704/html5/thumbnails/15.jpg)
The 1st Generation Technology (1G)
It is an Analog cellular network , uses multiple cell sites, and has the ability to transfer calls from one site to the next as the user travelled between cells during a conversation .
The first cellular network in the world was built in 1977 in Chicago and turned on in 1978. By the end of 1978 it had over 1300 customers. In 1979 a cellular network (1G generation) was launched in Japan by NTT. As the system expanded and neared capacity, the ability to reduce transmission power allowed new cells to be added, resulting in more, smaller cells and thus more capacity.
1G Frequency bands
![Page 16: Mask Lte Planning Tool](https://reader035.vdocument.in/reader035/viewer/2022081418/5578a68dd8b42a4d4b8b4704/html5/thumbnails/16.jpg)
The 2nd Generation Technology (2G)
The 2G is also known as Global System for Mobile communication (GSM). It is a digital mobile telephony system that is widely used in Europe and other parts of the world. GSM uses a variation of time division multiple access (TDMA) .
GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot.
GSM operates at either the 900 MHz or 1800 MHz frequency band.
Mobile services based on GSM technology were first launched in Finland in 1991.
Today, more than 690 mobile networks provide GSM services across 213 countries and GSM represents 82.4% of all global mobile connections. According to GSM World, there are now more than 2 billion GSM mobile phone users worldwide.
![Page 17: Mask Lte Planning Tool](https://reader035.vdocument.in/reader035/viewer/2022081418/5578a68dd8b42a4d4b8b4704/html5/thumbnails/17.jpg)
Basic Services of 2G technology
Voice services (speech coding with protection) Full rate: 13 / 12.2 Kbit/s (original coder / enhanced full rate coder) Half rate: 5.6 kilo bit/s (enhanced half rate coder). Data services (coding with different levels of protection) Full rate: 9.6 / 4.8 / 2.4 Kbit/s Half rate: 4.8 / 2.4 Kbit/s.
Advantages of the 2G :
1-Extensive Coverage.2-Greater Phone Variety.3-No Roaming Charges on International Calls.4-Huge Capacity.5-Low Power Consumption.6-Enhanced Range Of Service (Data + Voice ).Disadvantages of 2G:

Coverage Dimensioning Process
The target of coverage dimensioning is to estimate the maximum distance between a transmitter and a receiver while fulfilling the given system performance requirements under specific propagation conditions.
The main parameters affecting the coverage dimensioning process: frequency. Receiver & Transmitter heights. Transmitted power. Propagation environment.
![Page 58: Mask Lte Planning Tool](https://reader035.vdocument.in/reader035/viewer/2022081418/5578a68dd8b42a4d4b8b4704/html5/thumbnails/58.jpg)

Uplink Coverage Calculations
Most mobile telephony systems are frequently limited by the uplink, so it is useful to start link budget calculations with the uplink coverage requirements.
The calculations are performed according to the following stages: Bitrate ( Rrb ) requirements . SINR requirements . E-Node B receiver sensitivity . Uplink noise rise ( interference margin ) . Total losses. User equipment power per resource block . Uplink budget .

Margins
In LTE a user does not interfere with other users in the cell since they are separated in the frequency domain. The noise rise in the uplink depends only on interference from adjacent cells. In the link budget, an interference margin IMUL compensates for noise rise.

2.C# Programming Language
C# is a language designed to be fully compatible with Microsoft's .NET initiative while taking advantage of what has been learned from C++ and Java. We will use Microsoft Visual Studio 2010 to use C# programming.
We chose C# because it is very compatible with ArcGIS Server, easy to use in programming codes and functions with it’s digital maps beside as we run a web application here so we think the best combination to reach our target is by using Arc-GIS maps as a data base with C# as a programming language
We prefer to run a WEB application, Since the world trends to use WEB applications and all data stored on server not like normal Desktop applications, and we’ve find the best option we got here is “ASP.NET with JavaScript(JS)” application.

Future Work
Great effort has been made in order to make this work complete in all aspects, but as with all the projects, there is always a room for improvements and further enhancements. Same is the case with this thesis work. There are number of ways in which this work can be carried forward. A progressive work can be achieved through studying the detailed planning area which includes; frequency planning, neighbor planning and parameters planning. In addition to introducing the GIS maps in 3D which in turn will offer new opportunities in the tool as real prediction and simulations of the RF signal level in a real traffic distribution.
