Seminar Report on 3G and 4G Technology covers details about different levels of development. Below we provide detailed explanation on development stages.
Introduction to 1G and 2G:
The 1G system are analog systems which use radio signals for communication. FDMA technique is used for transmission of signals. In 2g systems digital radio signals are used for communication. TDMA and CDMA techniques are used for transmission of signals.
Features and Drawbacks of 1G and 2G:
In 1G only phone calls are possible and it has many drawbacks like poor quality of signal and noise interference. In 2G along with phone calls , voice mail and email messages were included. It has a transmission speed of 10kb/sec. in between 2G and 3G 2.5G has come which has GPRS technology and has transmission speed of about 64-144kbps. It include facilities like web browsing and navigation facilities.
Overview of 3G and 4G:
In order to meet the growing network demands 3G technology has come into existence. It has additional features like video calling, fax and TV streaming and high speed web. It has a browsing speed of about 144-2mbps. In 3G WCDMA technique is employed which allows multiple users on a common carrier signal.
Coming to 4g technology VSEOFCM technique is employed for data transmission. It has a band width of 5.20mhz and transmission speed of about 100mbps. But for the usage of 3G and 4G technology the networks has to be modified and 3G compatible phones has to be used for accessing. At present only some of the countries has switched to 3G technology and the companies started modifying the networks for the wide spread use of 3G technology. The call charges are a bit higher when compared to that of 2G networks. Thus we can conclude that the usage 3G technology has many features and reduces the loss of time for data transmissions.
