2. 4G is not one defined technology or standard,but
rather a collection of technogies at creating fully
packet switched networks optimized for data.
4G Networks are projected to provide speed of
100Mbps while moving and 1Gbps while
stationary
3.
4. 1G refers to the first-generation of wireless
telephone technology was developed in 1970’s
1G had two major improvements:
the invention of the microprocessor
the digital transform of the control link between the
phone and the cell site.
Analog signal
5. Around 1980’s
Better quality & capacity - More people could
use there phones at the same time
Digital Signals – consist of 0’s & 1’s
6. Allows for lower powered radio signals that
require less battery
Power–CODEC introduction -program that
encodes and decodes digital data stream or
signal
Translates data from digital to analog and vice
versa
7.
8. The digital voice encoding allows digital error
checking
increase sound quality
lowers the noise level
Going all-digital allowed for the introduction
of digital data transfer
SMS –“short message service”
E-mail
9. Cell towers had a limited coverage area
Jagged Decay curve
Discontinuous dropped calls
Analog –gradual sound reduction
“Spotty” coverage
10.
11. Large capacity and broadband capabilities
Allows the transmission of 384kbps for mobile
systems and up to 2Mbps
High data rates at lower incremental cost than
2G–Global roaming
12. HSPDA-High speed down link packet access
3.6 Mbps-14.2 Mbps
HSPA + evalved high speed packet access
1Mbps- 7Mbps
13. High input fees for the 3G service licenses
Great differences in the licensing terms
3G phones are expensive
14.
15. 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
OFDM used instead of CDMA
Most information is proprietary
16. self organization of
networks of devices
Not necessarily
connected to internet
4G will create hybrid
wireless networks using
Ad Hoc networks
17. 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.
18. 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
19. 4G LTE- long term evolution
100Mbps(down) 50Mbps(up)
4G WiMax-world wide interoperability for
micro wave access
128Mbps(down) 56Mbps(up)
