3G/4G & Next Generation Mobile Technology • What is 3G? refers to the third generation of mobile telephony (that is, cellular) technology. The third generation, as the name suggests, follows two earlier - 3G refers to the third generation of mobile generations. telephony (that is, cellular) technology. The third generation, as the name suggests, follows two earlier generations (1G & 2G). - At the moment 3G is a well-established mainstream mobile technology around the world. - In Bangladesh,3G has not been implemented commercially.

System/Protocol architecture

The Core Network The XG architecture contains a core IP network that has relatively little intelligence. Thus, most core network functions, such as routing, are handled by existing and evolving IP technology.

Conti-



The High Level Control Layer - Above the core is what we call a high-level control layer. It is important to specify not only what this layer does but what it does not not do. do. In particular, it does not provide functions for routing or call path setup, unlike the control layer of SS7 in the PSTN, but leaves that to the core. - It focuses on functions f unctions that can be made available to applications and overlay network elements, such as access to decision points for AAA, agents for mobility management, and role and rule assignment for policy management. Conti-


•


Access Networks - Below the core is a collection of access networks that serve different market niches and needs. - The 4G RAN is the evolution of the current RAN toward t oward higher data rates, support for interactivity and multimedia, and distributed control elements interconnected by an IP network.

Overlay layer - Finally, the XG architecture has an Overlay layer that provides higher-layer functionality and support services for applications, such as Application Layer Multicast (ALM), location services, and content distribution.


Evolution of Mobile Network

Generation of Mobile Network


Evolution of Mobile Network

•

First generation (1G): Analog voice systems

•

Second Generation (2G): Digital voice systems

•

Second Generation – advanced (2.5G): Combining voice and data communications Third Generation (3G): Digital voice and data communications – Developing a more general mobile network • Handling Internet access, email, messaging, multimedia • Access to any services (voice, video, data, etc.) – Requires high quality transmission Fourth Generation (4G): All-IP mobile networks – Ubiquitous wireless communications – Transparent to any services

•

•

3G/4G & Next Generation Mobile Technology • Application •

Voice - Voice is and remains the most important type of application in mobile telecommunications. - The most important features of ASCI include the following: • Voice broadcast service (VBS): the capacity for a single mobile to talk to a group of mobiles; • Voice group call service (VGCS): the capacity for a group of mobiles to talk to each other; • Enhanced multilevel priority and preemption (EMLPP): The fact that urgent calls can preempt less urgent calls.

Application

•

Messaging



Multimedia Messaging Services (MMS) – Text, sounds, images, and video – Transition from Short Message Service (SMS) – Open Internet standards for messaging

•

Internet Access



Web Applications – Information portals – Wireless Markup Language (WML) with signals using Wireless Application Protocol (WAP) Conti-


Application

Location-Based Applications Emergency services • E911 - Enhanced 911 Value-added personal services • Friend finder, directions Commercial services • Coupons or offers from nearby stores Network internal • Traffic & coverage measurements

Conti-


Application

Lawful intercept extensions • Law enforcement locates suspect Location (in 3D), speed and direction • With timestamp Accuracy of measurement Response time • a QoS measure Security & Privacy •authorized clients, secure info exchange, privacy control by user and/or operator Conti-


Application

Games - Games will be another major application segment in 3G/4G.

• Electronic Agents - Electronic agents are supposed to play an important role for mobile working in the future – as agents are dispatched to carry out searches and tasks on the Internet and report back to their owners. - They will be e-assistance, e-secretaries, e-advisors, e-administrators etc. This kind of control is what home automation applications anticipate. Conti-


Application

• Dating Applications - These are already very popular in Asia. - It can be a simple bulletin board with dating adverts combined with an anonymous anonymous e-mail server, or it could be a lonely-hearts mobile chat room. • Adult Entertainment - And the last in this list, but certainly not the least profitable, is the adult entertainment sector. This is the most profitable entertainment business in general, and it will remain so in 3G. The premiums will be very high.


Advantages Adv antages of 3G/4G/ Next Generation Mobile Technology

•

3G/4G visions take into account installed base and past investments.

•

Strong position of telecommunications t elecommunications vendors expected in the marketplace.

•

Faster data transmission and higher bit rate and bandwidth,, allow more business applications and bandwidth commercialization.

•

Has advantage for personalized multimedia communication tools.


Limitation of 3G/4G/ Next Generation Mobile Technology

•

No large user community for advanced mobile data applications yet.

•

Growing divergence between telecommunications t elecommunications vendors and operators.

•

Not possible to offer full internet experience due to limited speed and bandwid bandwidth. th.

•

Comparatively higher cost to use and deploy infrastructure compared fast mobile generation.

•

Since 3G mobile is still in the market, 4G reduces the market competition in the mobile industry.


Prospects of 3G/4G/ Next Generation Mobile Technology

•

Evolutionary approach may yield opportunities for the 3G/4G.

•

Emphasis on heterogeneous networks capitalizes on past investments.

•

Strategic alliance and coalition opportunities with traditional non-telecommunication industries.

•

Sophisticated and mature commercialization of 3G/4G technology would encourage encourage more applications of ecommerce and m-commerce. Conti-



•

Worldwide economy recover stimulates consumption and consumer confidence, therefore bring in opportunities for telecommunication sections.

•

It is expected and predicted that consumers will continue to replace handsets with newer technology at a fast rate.

•

Desirable higher data capacity rates, the growth opportunity for 3G/4G is very bright and hopeful. Conti-


•


5G (Real wireless world) (completed WWWW: World Wide Wireless Web): - The idea of WWWW, World Wide Wireless Web, is started from 4G technologies. The following evolution will based on 4G and completed its idea to form a REAL wireless world. Thus, 5G should make an important difference and add more services and benefit to the world over 4G; 5G should be a more intelligent technology that interconnects the entire world without limits.

3G/4G & Next Generation Mobile Technology • Conclusion •

This term paper was based to differentiate between 3G & 4G.

•

4G just right started from 2002 and there are many standards and technologies, which are still in developing process.

•

Therefore, no one can really sure what the future 4G will look like and what services it will offer to people.

•

4G is the evolution based on 3G’s limitation and it will fulfill the idea of WWWW(5G), World Wide Wireless Web, offering more services and smooth global roaming with inexpensive cost.
