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
LITERATURE SURVEY OF 3Go First launched by : NTT DOCOMO o BRANDED FOMAo Pre-release of WCDMA technology

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
