Mobility is one of the most invigorating features, having
an enormous impact on how communication is evolving
into the future.
Mobility in 5G networks requires new level of mobility
support as compared to traditional mobility.
0G refers to pre-cellular mobile telephony technology
in 1970s. These mobile telephones were usually
mounted in cars or trucks, though briefcase models
were also made.
Since they were the predecessors of the first generation
of cellular telephones, these systems are referred to
as 0G (zero generation) systems.
PTT(push to talk)
MTS(mobile telephone system)
AMTS(Advanced mobile telephone system)
First-generation mobile systems used analog
transmission for speech services.
A voice call gets modulated to a higher frequency of
about 150MHZ and it is transmitted between radio
towers using Frequency-Division Multiple
FDMA(Frequency Division Multiple Access)
NMT(Nordic Mobile Telephone)
AMPS(Advanced Mobile Phone System)
Disadvantages of 1G
It has low capacity, unreliable handoff, poor voice
links, and no security at all since voice calls were
played back in radio towers, making these calls
susceptible to unwanted eavesdropping by third
Very slow speed 28kbits/s to 56kbits/s.
The 2G introduced services for mobile, with SMS text
2G has been superseded by newer technologies such as
Advantages over 1G
Consumes less battery power.
Improves the voice clarity.
Reduce noise in the line.
Secrecy and safety to the data and voice calls.
2G networks were built mainly for voice data and slow
transmission. Due to rapid change in user expectation
they do not meet today’s wireless needs.
3G networks provide the ability to transfer voice and
no-voice data over the same network simultaneously.
HSPA(high speed packet access)
It is a combination of HSDPA (High Speed Downlink
Packet Access), HSUPA (High Speed Uplink Packet
Access) and HSPA+.
Data speed: 3.6Mbps-14.4Mbps.
Combines a mobile phone, laptop pc and TV
Send/receive large Emails
High speed web
4G development focuses around achieving ultra-
4G average speeds are in 100mbps to 1Gbps,roughly 10
to 100 times faster than 3G networks.
Protocol (IP) based communication such as IP
IP based mobile system .
High speed, high capacity, and low cost per bit .
Global access, service portability, and scalable mobile
Ad hoc and multi hop networks (the strict delay
requirements of voice make multi hop network service a
