implementation of wifi hotspots through HSDPA
CHAPTER 1
INTRODUCTION
In this project, the wifi hotspot is implemented using HSDPA because of its features like Hybrid ARQ , Adaptive modulation and coding, High speed downlink shared channel. This features enhance wifi hotspots to support an evolution towards more sophisticated network and multimedia services, the main target of HSDPA is to increase user peak data rates, quality of service, and to generally improve spectral efficiency for downlink asymmetrical services. HSDPA can achieve theoretical data transmission speeds of 8-10 Mbps(megabits per second). Though any data can be transmitted, applications with high data demands such as video and streaming music are the focus of HSDPA. Hence by implementing HSDPA in wifi hotspots theoretical data rates of about 10 Mbps can be achieved even in wifi hotspots.
1.1 ADVANCEMENT OF CELLULAR STANDARDS There is a rapid development of technology, mobile phones nowadays can do so much more than merely cellular communication. They have become smarter, not only name-wise, but also application-wise. Incorporating wireless data access technology, mobile phone has brought communications to another level offering mobility to the formerly fixed internet service. Web browsing, online video streaming, emailing and instant messaging previously monopolized by computers are now penetrated by third-generation mobile phones. The wireless data standards are the keys to the world of World Wide Web. The advancement in technology is stated below.
1.1.1 GPRS GPRS (General Packet Radio Service) which is also known as 2.5G can deliver data rate up to 114 kbit/s theoretically, yet its typical rate is usually around 56kbit/s. Video conferences and interaction with multimedia websites are for the first time made possible, but often with frequent lagging. This technology allows you to download some ringtones and games, but it will not be the choice for those with heavy internet consumption.
