1st Generation:
Introduced in 1980’s
Analog cellular mobile
Data speed 2.4kbps
Uses FDMA techniques with 30KHz
2nd Generation :
First digital mobiles-1990’s
Data support : 9.6-19.2Kbps
Used for voice transmission
Uses circuit switched network
3rd Generation :
Because of low speed and incompatible technologies 3g is arrived
Data rates are 128Kbps for mobile stations
For fixed applications 2Mbps
Universal global roaming multimedia
video calling
Increased bandwidth and transfer rates accommodate web-based applications
4th Generation :
High-speed data access
High-quality video streaming
Combination of Wi-Fi and Wi-max
5th Generation :
It is a packet based network
Data rate is 20Mbps
Frequency band is 2.8GHz
It is a network with wide area coverage and throughput
Need of IPv6 :
When a computer somewhere on the Internet needs to communicate
with the cell phone,
It first sends a packet to the phone's home address.
A directory server on the home network forwards
this to the care-of address via a tunnel,
The directory server also sends a message to the
computer informing it of the correct care-of address,
so future packets can be sent directly.
Because of the many addresses and the multiple
layers of sub netting, IPv6 is needed for this type
of mobility.
Importance of IPv6 :
IPv6 addresses are 128 bits, which allow for approximately three hundred and
forty trillion unique IP addresses
E.g.: 2001:db8:ff:1:201:02ff:fe03:0405
IPv6 allows more users and devices to communicate on the Internet by using
bigger numbers to create IP addresses
IPv6 also relieves other networking issues that can arise due to the limited
number of addresses available on IPv4
IPv6 Extend the IP address space enough to offer a unique IP address to any device
for providing global connectivity and mobility among networks.
