3. 2nd GENERATION:
Digital cellular systems
Digital modulation schemes-
Data speed in 2g is up to 64kbps
Data speed in 2.5g is up to
GPRS, EDGE and CDMA 2000 were
4. 3rd GENERATION:
3g technology is intended for true
multimedia cell phone
typically called smart phones and
features increased bandwidth and
transfer rates to accommodate
wed-based applications and
phone-based audio and video files
universal global roaming

6. WHAT IS 5G???
5G is a packet switched
wireless system with wide
area coverage and high
5G wireless uses OFDM and
millimeter wireless that enables
data rate of 20 mbps and
frequency band of 2-8 GHz.
5G is going to be a packed
7. OBJETIVES OF 5G:
5G being developed to accommodate QoS rate requirements
set by further development of existing 4G applications.
Flexible channel bandwidth between 5 and 20MHz,
optionally up to 40MHz.
Data rate of at list 1Gb/s between any two points in the
Increase system spectral efficiency of up to 3bit/s/Hz/cell
in the downlink and 2.25bit/s/Hz/cell for indoor usage.
8. STANDARD WIRELESS 5G:
WiMAX formed to provide conformance and interoperability of
the IEEE 802.16 standard. It aims to provide wireless data over
long distance from point-to-point link to cellular mobile type
WiBRO a part of IEEE 802.16e in process to provide
collaborative and generic mobile WiMAX.
3GPP LTE a project aims to improve the mobile phone
standard to cope with future requirements.
5GPP 2 UMB a project to improve the CDMA2000 mobile
phone standard for next generation applications.
10. IPv6 SUPPORT:
IPv6 increases the IP addresses size from 32bit to 128 bits, to
support more levels of addressing hierarchy and much greater
number of addressable node.
IPv6 support large number of wireless enabled devices.
IPv6 Extend the IP address space enough to offer a unique IP
address to any device.
IPv6 Improve support for IP Mobility.
