The document presents a project on wireless communication. It discusses the basics of wireless communication including definitions and block diagrams. It describes the four generations of wireless technology (1G to 4G) and their key features such as speed and capabilities. The document also discusses GSM architecture and different types of handovers. It provides an overview of radio frequency surveys and planning, including the tools, steps, and parameters involved.

2. Wireless communications is a type of
data communication that is performed
and delivered wirelessly.

Definition:

3. Block diagram of wireless
communication:

4. Generations:
• 1st generation (1G)
• 2nd generation (2G)
• 3rd generation (3G)
• 4th generation (4G)

5. 1G:
 1G is pure analog system
 FDMA
 AMPS(analog mobile phone system)
 Only voice
 Poor handoff

6. 2G :
 GSM(global system for mobile communication)
 Voice and data
 Works on 900,1800,1900 bands
 FDMA and TDMA
 Speed up to 64kbps

7. 3G:
 Speed increased to 2mbps.
 Video calling and TV streaming.
 WCDMA
 High security and performance.

8. 4G:
 LTE (long time evolution).
 Speed 100Mbps to 1Gbps
 High speed and capacity
 More security

9. GSM architecture :

10. handover

11. According to area :
 Four types of handover
1. Intra BTS handover
2. Intra-BSC handover
3. Inter-BSC handover
4. Inter-MSC handover

12. According to frequency :
 Hard handover (break before make)
 Soft handover (make before break)

13. RF Survey & RF
Planning

14. RF Survey : It is a process of identifying
the cell site location or feasibility of cell site
location & to get the basic knowledge of the site.
It is of 2 types :
1. Anchor Survey
a)Nominal survey
b)Blind survey
2.Sharing Survey

15. Tools Used For Survey :
i) GPS ii) Magnetic Compass iii) Digital Camera
v) Site Data / Reference latitude/ longitude
vi) Stationary
vii) R.F. Form
iv) Measuring Tape:

16. RF Survey report

17. As Planned:

E :78.53004
GPS :

18. SITE @0˚ SITE @30˚
SITE @ 60˚ SITE @ 90˚

19. SITE @ 120˚ SITE @ 150˚
SITE @ 180˚ SITE @ 210˚

20. SITE @ 240˚ SITE @ 270˚
SITE @ 300˚ SITE @ 330˚

21. ANTENNA 1 @0˚ ANTENNA 2@ 60˚
ANTENNA @240˚

22. RF Planning :
The three steps are as follows
STEP 1:- PREPLANNING OF NETWORK
STEP 2:-SURVEY
STEP 3:-POST PLANNING OF NETWORK

23. Preplanning of network :
• In Preplanning of a network, sites are established on
the map in the software without taking into
consideration the feasibility of the sites.

24. Open the ATOLL SOFTWARE and select the 3GPP MULTI-RAT.

28. Place the sites 0-5 of GSM UMTS and LTE.

29. Select an antenna and open the properties dialogue box
appears.

30. Now define the neighbours ( intra-technology , GSM and
UMTS ) of each antenna.

34. Now provide the coverage using signal level.

38. POST PLANNING :
In post planning of the network the site is moved to the actual feasible location, all the
parameters are adjusted to give coverage to the targeted location in this case telcocrats
technologies as shown in the pictures.
Change the angles of the antennas.

41. Now define the neighbours of all the antennas.

42. Now calculate the coverage of sites by signal level.
