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.
1G WIRELESS SYSTEMDeveloped in 1980s and completed in early 1990’s
1G was old analog system and supported the 1st 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
