Mobile System Generations

First Generation (1G) mobile systems were designed tooffer a single service, i.e., speech.

Second Generation (2G) mobile systems were also

designed primarily to offer speech with a limited

capability to offer data at low rates.

Third Generation (3G) mobile systems are expected to

offer high-quality multi-media services and operate in

different environments.

3G systems are referred to as Universal Mobile

Telecommunications System (UMTS) in Europe and International

Mobile Telecommunications 2000 (IMT2000) worldwide.

3G Realities

A recent study by Herschel Shosteck Associates noted

that operators that pay large amounts for spectrum will

have to charge end users so much that adoption of 3G

will be slow.

Another study by Strategy Analytics agreed, predicting

that, while wireless data revenues will soar, 3G

networks will account for less than a quarter of that

revenue by 2010. So-called 3G killer apps such asmultimedia won't succeed, the second study said.

What is fourth generation (4G)

mobile systems?

Fourth generation mobile communications

systems that are characterized by high-speed

data rates at 20 to 100 Mbps, suitable for high-

resolution movies and television, virtual.Initial

deployments are anticipated in 2006-2010.

Agent Definition

An agent is a software component (object) that issituated within an execution environment (e.g. computers)

and acts autonomously on behalf of a user or process

and has specific goal.

Agent Technology

Mandatory features

Reactive: senses changes in the environment andreacts in accordance.

Autonomous: has control over its own actions

Goal-driven: is pro-active

Optional features

Collaborative: communicates/negotiates with other

agentsMobile: travels from one host to another

Learning: adapts in accordance with previousexperience

Believable: appears believable to the end-user.
