INTRODUCTION TO WIRELESS COMMUNICATION Our ultimate goal is to communicate with any type of information with anyone, at anytime, from anywhere. This is possible with the aid of WIRELESS TECHNOLOGY
MULTIPLE ACCESS APPROACHES AND NETWORKS IN MULTINETWORK
EVOLUTION OF CELLULAR SYSTEM
1G WIRELESS SYSTEM Developed in 1980s and completed in early 1990 s 1G was old analog system and supported the 1 st generation of analog cell phones speed up to 2.4kbps Advance mobile phone system (AMPS) was first launched by the US and is a 1G mobile system Allows users to make voice calls in 1 country
2G WIRELESS SYSTEM Fielded in the late 1990s and finished in the late 1998s Planned for voice transmission with digital signal and the speeds up to 64kbps 2G was the digital handsets that we are used today, with 2.5G representing handsets with data capabilities over GPRS,SMS.
3G WIRELESS SYSTEM Developed in 2002 with Large capacity and broadband capabilities Allows the transmission of 384kbps for mobile systems and up to 2Mbps Increased spectrum efficiency 5Mhz In 2005, 3G is ready to live up to its performance in computer networking (WCDMA, WLAN and Bluetooth) and mobile devices area (cell phone and GPS)
4G WIRELESS SYSTEM Developed in 2010.It offer both cellular and broadband multimedia services everywhere Faster and more reliable Multi-standard wireless system 100 Mb/s Used instead of CDMA Lower cost than previous generations
Problems in 4G SMS - very low rate, highly delay-tolerant & requires more reliability than voice E-mail - very low rate, highly delay-tolerant & requires more reliability. The potentially high level of traffic variation (non-uniformity) across the area of network s coverage. The fluctuations in traffic demand (both in space and time) will be at unprecedented levels in future networks, which will result in tremendous stress to wireless operators.
5G WIRELESS SYSTEM 5G is next major phase of mobile telecommunications standards beyond the 4G 10 times more capacity and broadband capabilities than other Expected speed 1GB/S More Faster and more reliable than 4G Mobile Multimedia Communication
Anywhere, Anytime with Anyone Global Mobility Support Integrated Wireless Solution Customized Personal Service Multi-standard wireless system Lower cost than previous generations
Functional architecture for 5G mobile networks
THE 4A PARADIGM 5-G wireless technology is fulfill for 4A PARADIGM 4A paradigm:- Any rate, Anytime, Anywhere, Affordable.
FEATURES OF 5G TECHNOLOGY Bi-directional large bandwidth. Large broadcasting. Less traffic. 25 Mbps connectivity speed. Connectivity just about the world. Uploading and downloading speed of 5G technology touching the peak.(up to 1GBPS). Better and fast solution. Based on Policy to avoid error. Support virtual private network. More attractive and effective.
