Transcript of LTE Dimensioning
What is LTE?!
=> Long Term Evolution
LTE is the next generation of the mobile broad band technology
Data rate from 100 to 300 Mbps
It's the next level after UMTS (3G) technology
LTE technical aspects

e designed a tool by using
language, has the ability to calculate the actual number of cells need to cover a certain area by
technology via using
ricsson technology for
Spectral efficiency 2 to 4 times times more than HSPA technology (release 6).
Peak rates exceed 100 Mbps in downlink & 50 Mbps in uplink.
Decrease the latency comparing to 3G technology
Throughput according to shannon's theory:-
C = B log2 (1+SNR)
Band width on demands up to 20 Mhz
LTE network architecture
Network Service Area
Standard Of Livings
Dimension Of Site
Dimensioning Flow Chart
MIMOGains, Diversity&Beam Forming
Noise Rise in DL
Average DL SINR
DL average bit rate per resource block
LTE (Release 8)
Peak Data Rate
16.3 (4x4 MIMO)
30 (Up to 8x8 MIMO)
4.3 (64 QAM SISO)
15 (Up to 4x4 MIMO)
Why we used C#?!
1. Independent Platform :
Work in any environment ( Windows, Linux, MAC,…etc.).
Don’t need to develop different versions for each platform.
2. Object oriented programming :
Easily debugged and modified.
DL average user bit rate
Cell Throughput in DL
=> Fitted Parameteres
From Okumora-Hata propagation model we can get the cell radius leading to simply calculate cell area and site count.
DL noise rise at cell edge
DL cell edge SINR
The target of our project was to design a tool able to make automatic cell planning and how to use our resources in the best usage to get the best result, also how to calculate the bit rate for the network to get the best data rate for network users.
To use 3D maps instead of 2D maps.
Draw the actual coverage antenna shape via draw the real dimensions of the antennas.
To design a tool abl to edit previous projects to avoid building projects from scratch.
