HSDPA(High Speed Downlink Packet Access) improves system capacity and increases user data rates in the downlink direction, that is, transmission from the Radio Access Network to the mobile terminal. This module, which is designed to supplement the UMTS Air Interface tutorial, explores the HSDPA channel architecture along with the additional functionality required in the UMTS MAC (Medium Access Control) layer. The processes of adaptive modulation and coding along with procedures by which HSDPA data is scheduled for transmission across the air in ....etc

The Ping of Death uses a ping system utility to create an IP packet that exceeds the maximum 65,536 bytes of data allowed by the IP specification. The oversize packet is then sent to an unsuspecting system. Systems may crash, hang, or reboot when they receive such a maliciously crafted packet. This attack is not new, and all OS vendors have fixes in place to handle the oversize packets.

High-Speed Downlink Packet Access (HSDPA) (Sometimes known as High-Speed Downlink Protocol Access) is a 3G mobile telephony protocol in the HSPA family, which provides a roadmap for UMTS-based networks to increase their data transfer speeds and capacity. Current HSDPA deployments now support 1.8 Mbit/s, 3.6 Mbit/s, 7.2 Mbit/s and 14.4 Mbit/s in downlink.

Further speed grades are planned for the near future. The networks are then to be upgraded to HSPA Evolved, which provides speeds of 42 Mbit downlink in its first release.

The topic is related to improving end-user experience for web browsing services in the HSDPA scheduler.

I wanted to ask some questions related to it.

The basic idea is to identify web browsing applications in the WRAN from their traffic characteristics, define the user requirements for them and then basically optimizing the application in order to improve the scheduling algorithm in hsdpa.
For the web browsing services, the characteristics I have taken into account are, i.e. with these characteristics we would be able to identify web ....etc

A speech needs time to grow. Prepare for weeks, sleep on it, dream about it and let your ideas sink into your subconscious. Ask yourself questions, write down your thoughts, and keep adding new ideas. As you prepare every speech ask yourself the following questions.

In one concise sentence, what is the purpose of this speech?
1) Who is the audience? What is their main interest in this topic?
2) What do I really know and believe about this topic as it relates to this audience?
3) What additional research can I do?
4) What are the main ....etc

1) Take into consideration that you were most likely asked to speak because you have knowledge about the topic.
2) The most important thing --- don't panic. If you can, find a copy of the presentation handouts and scan them, writing down the main topics for each portion of the presentation.
3) This allows you to quickly look at the content of the presentation.
4) If the original speaker planned to use slides, quickly skim each slide and write down the key points.
5) Do not concern yourself with the exact words on the slide.
6) If the sli ....etc

High Speed Downlink Packet Access (HSDPA) – A Means of Increasing Downlink Capacity in WCDMA Cellular Networks
Abstract:
The increasing demand for capacity in order to provide high data rate multimedia services in wireless environments necessitates enhanced radio transmission techniques and network protocol functionality. Such techniques have to be added to already existing mobile cellular networks, e.g. as provided by EDGE. For 3rd generation UMTS networks based on WCDMA, the High Speed Downlink Packet Access (HSDPA) is bein ....etc
