1xEV-DO Architecture for Wireless Internet seminar topic for B.Tech students / Seminar topics for the Electrical and Electronic Engineering Student

Millions of people around the world use the Internet every day -- to communicate with others, follow the stock market, keep up with the news, check the weather, shop, entertain themselves and also to learn. Staying connected has become so important that it's hard to get away from our computer and our Internet connection because we might miss an e-mail message or any news we need to know.

With the world's business and people's personal lives growing more dependent on communication over the Internet, we must be ready to take the next step and get a device that allows us to access the Internet on the go.

That's where Wireless Internet comes in. This revolution has coincided with the cellular boom in the last few years. The expanding network of digital cellular and personal communication services (PCS) has created a solid foundation for wireless Internet services

SEMINAR TOPICS FOR THE B.TECH STUDENTS ON "Multiterabit Networks"

The explosive demand for bandwidth for data networking applications continues to drive photonics technology toward ever increasing capacity in the backbone fiber network and toward flexible optical networking. Already commercial Tb/s (per fiber) transmission systems have been announced, and it can be expected that in the next several years, we will begin to be limited by the 50 THz transmission bandwidth of silca optical fiber. Efficient bandwidth utilization will be one of the challenges of photonics research. Since the communication will be dominated by data, we can expect the network of the future to consist of multiterabit packet switches to aggregate traffic at the edge of the network and cross connects with wavelength granularity and tens of terabits throughout the core.

The infrastructure required to govern Internet traffic volume, which doubles every six months, consists of two complementary elements: fast point-to-point links and high-capacity switches and routers. Dense wavelength division multiplexing (DWDM) technology, which permits transmission of several wave-lengths over the same optical media, will enable optical point-to-point links to achieve an estimated 10 terabits per second by 2008. However, the rapid growth of Internet traffic coupled with the avail-ability of fast optical links threatens to cause a bottleneck at the switches and routers.
