2. Contents:-
 BTS (Base Transreceiver System)
 Parameters for network optimization at MSC level
 Generation of wireless cellular system
 1st generation
 2nd generation
 GSM Architecture
 GPRS
 EDGE
 3rd Generation
 4th Generation

3. BTS (Base TransreceiverSystem):-
A BTS site contains:-
 Tower containing RF and microwave antenna
 Power supply containing SMPS(Simple Mode Power Supply)
and battery backup
 Shelter containing BTS device
 Jumper and feeder cables for the connection between BTS
and antenna
 DDF (Digital Distribution frame) perform bits formation

4. An actual BTS site:-

5. Parametersfor networkoptimizationat MSC
level:-
 ASR (Answer to Seize Ratio)
 PSR (Paging Success Rate)
 SCR (Success call Rate)

6. Generationsof wirelesscellular system:-
First Generation(1G)
Second Generation(2G)
GSM
GPRS
EDGE
Third Generation(3G)
Fourth Generation(4G)
LTE(Long Term Evolution)
Wi-Max(Worldwide Interoperability for
Microwave Access)

7. 1’st Generation(1G):-
 Works on analog system
 Related technologies-
(i) NMI(Nordic Mobile Technology)
(ii) TACS(Total Access Communication System)
(iii) NTACS(European Total Access Communication
System)
 Based on FDMA(Frequency Division Multiplexing)

8. SecondGeneration(2G):-
 Digital Communication first used
 Initial technology of 2G was called Groupe Special
Module which later converted to Global System for
Mobile Communication
 Used only for voice calling
 Channel distribution based on TDMA(Time Division
Multiple Access)
 Modulate 2-bit at a time
 Channel bandwidth of 200KHz is proposed

9. GSM Architecture:-

10. GSM Identifiers:-
 IMSI (International Mobile Subscriber Identity)
IMSI contains-
(i)MCC(Mobile Country Code) -3 Digit (404/405 for India)
(ii)MNC(Mobile Network code)-2 digits
(iii)MSIN(Mobile Subscriber Integrated Number)-10 digits
 MSISDN(Mobile Subscriber Integrated Service Digital
Number)
MSISDN Contains-
(i)CC(Country Code)-+91/0
(ii)NVM(National Valid Number)-MSC id + HLR id + Serial no

11. GPRS(GeneralPacketRadio Service):-
 Data transmission was introduced
 Data speed of up to 20-50 kbps
 Based on packet switching

12. EDGE(EnhanceData rate for GSM Evolution):-
 Used for enhanced data rate(up to 200 kbps)
 8PSK modulation scheme is used
 3-bit modulation at a time so data rate increase up to 2 to 4
times
 Both voice and data transmission is possible

13. Third Generation(3G):-
 Proposed by 3GPP(Third Generation Partnership
Project)
 UMTS (Universal Mobile Terrestrial System) standard
was used
 Minimum speed of 200 kbps was defined for 3G
WCDMA(wideband CDMA) interface was used
 HSDPA(3.5G) and HSUPA(3.75G) was further introduced
for higher data
 Channel bandwidth is 5MHz

14. 3G Architecture:-

15. 4th Generation:-
Objective:-
 Download speed of 1 Gbps for stationary users and
100 Mbps for moving users
Fully packet switched network
Mobile ultra broadband concept(fixed speed to each
user)
Total IP based communication

16. 4G requirements:-
MIMO Technology
OFDMA concept
Smart Antenna
Flexible Bandwidth

17. 4G Architecture:-

18. 4G standards:-
4G
LTE Wi-Max
(Long Term Evolution)

19. LTE(LongTerm Evolution):-
Introduced by 3GPP
First proposed by NTT DoCoMo of Japan in 2004
Initial objective was to achieve downloading speed of
1Gbps and uploading speed of 100Mbps
LTE only achieved speed up to 300 Mbps
Further releases was introduced as LTE-A and LTE-B for
achieving the speed of 1Gbps

20. Wi-Max:-
IEEE 802.16 standard
Provide higher data rate of 70 Mbps
Provide services in 2 modes:-
i) Line-Of-Sight Mode(10-66 GHz)
ii) None Line-Of-Sight Mode(2-11 GHz)
Range of operation is 10-15 Km(Using Wi-Max Tower)
