QUALITY OF SERVICES CHALLENGES
1.Multi-access interface, timing and recovery.
2. Higher frequency reuse leads to smaller cells that may causeintra-cell interference or higher noise figures due to reduced
power levels.
3. The Digital to analog conversions at high data rates, multiuser
detection and estimation (at base stations), smart antennas and
complex error control techniques as well dynamic routing will
need sophisticated signal processing.
4. Issues in the interface with the ad hoc networks should be
sorted out. 4G systems are expected to interact with other
networks like the Bluetooth, hiperlan, IEEE802.11b, etc.
5. Voice over multi-hop networks is likely to be an interesting
problem because of the strict delay requirements of voice.7. Security will be an important issues
8. Networking protocols that adapt dynamically to the changing
channel conditions.
9. Seamless roaming and seamless transfer of services.

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

Communication Architecture
Broadcast layer: fix access points, (i.e.) cell tower
connected by fiber, microwave, or satellite
(ISP) Ad-hoc/hot-spot layer:
wireless LANs (i.e. internet at Starbucks)

OUR VIEW ABOUT 4G
it has large application good connectivity
access speed is good
broadband mobility access
it is good but the limitation of 4g should o
overcomed for the improvement of 4g

TECHNOLOGIES AFTER 4G
5G technology offer high resolution for crazy cell phone user and bi-
directional large bandwidth shaping.
The advanced billing interfaces of 5G technology makes it more
attractive and effective.
5G technology also providing subscriber supervision tools for fast
action.
The high quality services of 5G technology based on Policy to avoid
error.
5G technology is providing large broadcasting of data in Gigabit
which supporting almost 65,000 connections.
