3. 4G Definition
4G is not one defined technology or standard,
but rather a collection of technologies at creating
fully packet-switched networks optimized for
data.
4G Networks are projected to provide speed of
100Mbps while moving and 1Gbps while
stationary.
4. What is 4G?
Fourth Generation Technology
Faster and more reliable
100 Mb/s
Lower cost than previous generations
Multi-standard wireless system
Bluetooth, Wired, Wireless
Ad Hoc Networking
IPv6 Core
OFDM used instead of CDMA
Potentially IEEE standard 802.11n
Most information is proprietary
5. Communication Architecture
Personal Layer Gateway:
devices that connect to upper layers; cell phone, fax,
voice, data modem, MP3 players, PDAs
Info-Sensor layer:
environmental sensors
Fiber-optic wire layer:
high speed subterranean labyrinth of fiber optic cables
and repeaters
6. Ad-Hoc Networks
Spontaneous self organization
of networks of devices
Not necessarily connected to
internet
4G will create hybrid wireless
networks using Ad Hoc
networks
7. Enhance Mobile Gaming
Experience enhance wireless capabilities that
deliver mobile gaming interaction with less
than five seconds
Play online multi player games while traveling
at high speeds or sitting outside
8. Broadband Access In Remote
Areas
4G will provide a wireless alternative for
broadband access
It will provide first opportunity for broadband
access in remote locations without an
infrastructure to support cable or DSL
access.
9. LTE (Long-Term Evolution)
Specification managed by 3GPP organization
3rd
Generation Partnership Project
Scope to create global 3G spec based on GSM
architecture
UMTS (Universal Mobile Telephone System)
HSPDA (High Speed Download Packet Access)
HSPUA (Upload Access)
HSPA+ Rel 7, enhancements in Rel 8-10
New LTE specification in Release 8, 4G Scope
10. 4G LTE
An acronym for Long Term Evolution, LTE is a 4G
wireless communications standard developed by the 3rd
Generation Partnership Project (3GPP).
designed to provide up to 10x the speeds of 3G
networks for mobile devices such as
smartphones, tablets, netbooks, notebooks & wireless
hotspots.
4G LTE is one of several competing 4G standards along
with Ultra Mobile Broadband (UMB) & WiMax (IEEE
802.16).
11. 4G LTE Advance
LTE Advanced is a
mobile communication standard and a major
enhancement of the Long Term Evolution (LTE)
standard. It was formally submitted as a
candidate 4G system toITU-T in late 2009 as
meeting the requirements of the IMT-Advanced
standard, and was standardized by the
3rd Generation Partnership Project (3GPP) in
March 2011 as 3GPP Release 10
12. Continued…
The LTE format was first proposed by NTT DoCoMo
of Japan and has been adopted as the international
standard.
The first commercial services were launched
in Sweden and Norway in December 2009 followed by
the United States and Japan in 2010.
The work by 3GPP to define a 4G candidate radio
interface technology started in Release 9 with the study
phase for LTE-Advanced. Being described as
a 3.9G (beyond 3G but pre-4G).
