4G Hardware & Software

8. • WiMAX ,LTE,VoLTE.
• The advantages of LTE are:
 It offers both FDD and TDD
duplexing.
 100 Mbps - download &
50 Mbps – upload.
 Uses OF DM.
Technology
Standards

9. o WiMax technology might not
achieve the required rate in a
high- density area .
o Useful when it is bundled with
IPTV.
o The wireless bandwidth will be
roughly 3Mbps/1.5Mbps; but this
is nowhere near the
100Mbps/50Mbps that LTE
promises.
WIMAX

10. • OFDM stands for Orthogonal
Frequency Division Multi-
plexing.
• It distributes the data over
a large number of carriers
that are spaced apart at
precise frequencies.
OFDM

11. • The IP address is based on IPv6.
IPv4: X . X . X . X (32 bits)
example: 216.37.129.9
• IPv6: 4 × IPv4 (128 bits)
example:
216.37.129.9 (Home Address),
79.23.178.229(Care of Address),
65.198.2.10(Mobile IP address),
192.168.5.120 (Local network address)
How 4G Works?

12. • Virtual Presence
• Virtual Navigation
• Crisis Management Application
• Tele geoprocessing, telemedicine
• Security
Applications

13. • Support for multimedia
services at low
transmission cost.
• High usability: anytime,
anywhere, and with any
technology.
• Higher bandwidth, tight
network security.
• Expensive.
• Battery uses are more.
• Hard to implement.
• Need complicated hardware.
