Wireless Standard Evolution

Overview of wireless generations from 1G of 4G

• Paste that Table in Page 4 & 5 in the doc here and explain about that.

GPRS (General Packet Radio Service)

• It is a packet switched wireless protocol for global system for mobile communications (GSM) that mirrors the Internet model and enables seamless transition towards 3G networks.

• it is also designed to work on TDMA (Time Division Multiple Access) standard used by many mobile vendors.

• The real advantage of GPRS is that it provides an ‘ALWAYS – ON’ connection between mobile terminal and the network.

• SPEED is main advantage over existing networks. • HIGHER BANDWIDTH enables applications such as low quality

video monitoring or music download.• Packet switching replaces the circuit switched transfer mechanism

of GSM. • SPECTRUM is used efficiently.

Working of GPRS

GPRS PROTOCOL LAYERING

WAP (Wireless Application Protocol )

• The internet and mobility are main drivers behind our economy.

• WAP the defacto standard, is essentially a browsing protocol, brings them together enabling anywhere anytime access to information from any device over any network.

• The idea behind WAP is to take a client server approach with emphasis on the server doing most of the work.

• Its main feature is that it does not depend on any one specific underlying transport standards which means that WAP complaint services and applications run over all network types, both current and future.

How does WAP work ?

• The mechanism behind WAP communications is fairly simple comparable to IP.

THE WAP MODEL

WAP AND GPRS A GOOD MATCH

• To become practical and useful WAP needs precisely those upgrades that GPRS provides.

• GPRS is very efficient medium and it consumes far less air resources.

• Therefore the result is that operator cost for WAP over GPRS services are significantly lower than with WAP over CSD.

WAP AND GPRS A GOOD MATCH

• Packet Switching vs. Circuit Switching

• Instant access

• Higher Transfer rate

• Security

3G AROUND THE GLOBE

• Europe’s transition to 3G technology, generically called W-CDMA (Wide band Code Division Multiple Access) may begin sooner, the major hurdle being economical rather than technical.

• North America suffers from a lack of standardization on 2G cellular service. Some carriers use CDMA (Code Division Multiple Access) while others use TDMA (Time Division Multiple Access).

• In Japan, NTT Dacomo has announced the launch of 4Gservices dubbed FOMA (Freedom of Mobile Multimedia Access).

Conclusion

• The world is witnessing the transformation of mobile phone from a voice centric communication device to a tool fro managing business and private life and sharing and storing experiences.

• WAP over GPRS together bring mobile services one step forward on the road of evolution towards 4G services.

• Although both standards have a lot of industry backing there is also a lot of pressure from competing technologies.

• If 3G is deployed soon, 2.5G technologies may not have sufficient to penetrate the market properly.

• Whatever happens, GPRS and WAP are useful migratory technologies, which will be, heard a lot more.
