- 4. WHAT IS A MOBILE ? • A mobile is a portable telephone that does not use a wired connection. It connects to a wireless carrier network using waves. INTRODUCTION
- 5. WHAT IS MOBILE COMMUNICATION ? • A wireless form of communication in which voice and data information is emitted, transmitted and received via microwaves. • This type of communication allows individuals to converse with one another or transmit data while moving from one place to another. INTRODUCTION
- 6. • 1G refers to the first generation of wireless telephone technology. • Mobile telecommunication was first introduced in 1980s and completed in early 1990s. • Data service almost non-existent. • It allows the voice call in 1 country. • 1G network use analog signal 1G TECHNOLOGY
- 7. DRAWBACKS: • Poor voice quality • Poor battery life • Large phone size • No security • Limited capacity 1G TECHNOLOGY
- 8. • 2G technology refers to the 2nd generation which is based on GSM. • It was launched in Finland in the year 1991. • 2G network use digital signals. • It’s data speed was up to 64kbps • It enables services such as text messages, picture messages or multi media message • It provides better quality and capacity. 2G TECHNOLOGY
- 9. DRAWBACKS: • These systems are unable to handle complex data such as videos. • 2G requires strong digital signals to help mobile phones work. If there is no network coverage in any specific area, digital signals would weak. 2G TECHNOLOGY
- 10. • 2.5G is a technology between the 2G and 3G • 2.5G is sometimes described as 2G cellular technology combined with GPRS Features includes: Phone calls Send/receive E-mail messages Camera phone Speed: 64-144 Kbps. 2.5G TECHNOLOGY
- 11. • 3G technology refer to third generation which was introduced in year 2006. • Data transmission speed increased from 144kbps – 2 Mbps. • Typically called smart phones • Accommodate web based applications and audio and video files. 3G TECHNOLOGY
- 12. FEATURES: • Provides faster communication • Send/receive large Email messages • TV streaming/ mobile TV • 11 sec – 1.5 min time to download a 3min MP3 song. 3G TECHNOLOGY
- 13. • 4G technology refer to fourth generation which was started from 2011. • Capable of providing 100Mbps – 1Gbps speed. • One of the basic term used to describe 4G is MAGIC: Mobile multimedia Any time anywhere Global mobility support Integrated wireless solution Customized personal services 4G TECHNOLOGY
- 14. DRAWBACKES: • Battery usage is more • Hard to implement • Need complicated hardware • Expensive equipment required to implement next generation network. 4G TECHNOLOGY
- 15. • 5G technology refer to fifth generation. • Complete wireless communication with almost no limitation. BENEFITS: • High speed, high capacity • Faster data transmission that of the previous generations. • Support interactive multimedia, voice, streaming video , internet 5G TECHNOLOGY
