WIRELESS TECHNOLOGY

The word wireless is dictionary defined as “having no wires.”

In networking technology , wireless means any computer where there is no physical wired connection between sender and receiver.

Radio waves or microwaves used to maintain communications.

FIRST GENERATION(1G)

FEATURES: Speed up to 2.4kbps. Voice calls in 1 country. Used Analog Signal.

SECOND GENERATION(2G) Based on GSM. Launched in1991. Digital signals. Data speed up to 64kbps. Text messages, picture

messages, MMS. Better quality and capacity.

DRAWBACKS OF 2G

GSM does not support high data rates Inefficient usage of bandwidth and

resources Unable to handle complex data Reduced range of sound Weaker digital signal

NEED FOR 3G!

80% of wireless subscribers Demand for high speed data services Interest in multimedia services To remove drawbacks of 2g

FEATURES OF 3G

Seamless roaming. Data rates : 2 Mbit/s for stationary 384 kbit/s in a moving vehicle High speed WEB. Greater security Improved voice quality.

APPLICATIONS OF 3G

Mobile internet connectivity. Mobile TV. Multimedia services. Downloading various applications Enhanced music on your mobile. Location based services. Taking games to the next level.

ADVANTAGES OF 3G

Support for multimedia data applications such as video and photography.

Faster data transfer rates. Cheap call rates worldwide. Capability to determine geographic

position of mobiles and report it. Anywhere access to internet.

DISADVANTAGES OF 3G

High spectrum licensing fees. Huge capital required to build

infrastructure. Health impact because of the

electromagnetic waves. Comparatively higher prices. Majority of users preferring 2G services.

4G Technology

5G TECHNOLOGY Next major phase of mobile

telecommunications standards. 10 times more capacity and

broadband capabilities than 4G. Expected speed 1GB/S Faster and more reliable than 4G
