High Speed OFDM Packet Access

High Speed OFDM Packet Access (HSOPA) also called as super 3G can be said as the successor of HSDPA and HSUPA technologies specified in 3GPP releases 5 and 6. This expected fraction of 3GPP s Long Term Evolution (LTE) upgrade path for UMTS systems has given a totally different air interface system with that of the W-CDMA.

The characteristics of HSOPA includes -:

· Utilizes 1.25 MHz to 20 MHz bandwidth compared with the 5MHz usage of W-CDMA.

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

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.

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

Revisiting Defenses Against Large-Scale Online Password Guessing Attacks




INTRODUCTION

Online guessing attacks on password-based systems are
inevitable and commonly observed against web applications
and SSH logins. In a recent report, SANS
identified password guessing attacks on websites as
a top cyber security risk. As an example of SSH
password-guessing attacks, one experimental Linux honeypot
setup has been reported to suffer on average

ABSTRACT

As the virtual centre of excellence in mobile and personal communications (Mobile VCE) moves into its second core research programme it has been decided to set up a fourth generation (4G) visions group aimed at harmonising the research work across the work areas and amongst the numerous researchers working on the programme. This paper outlines the initial work of the group and provides a start to what will become an evolving vision of 4G. A short history of previous generations of mobile communications systems and a discussion of t ....etc

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
