UMTS Devices

Virtual Home Environment

Virtual Home Environment is defined as a concept for personalized services portability between the terminals and across the network boundaries such that user is constantly presented with the same personal features, user Interface customization and services by the service provider where ever the user may be .The beauty of this setup is the freedom of personalized services enjoyed at the customer end provided by the UMTS, though this is just a beginning of the dream era but the offers made by the UMTS are much heart throbbing and the word VHE has become the dr

Introduction

Basically UMTS has been develope, evolved and adopted mostly in Europe. A survey was conducted in Great Britain, France, Germany, Spain, Italy and Belgium called as Harris Interactive Survey. The survey was aimed to capture people's response to the UMTS. This survey was conducted between 27 February and 4 March 2004, among 10,581 adults, from which 9,865 were determined to be mobile users.

Introduction

Location Based Services

A location-based service (LBS) in a cellular telephone network is a service provided to the subscriber based on his current geographic location. This position can be known by user entry or a GPS receiver that he carries with him, but most often the term implies the use of a radiolocation function built into the cell network or handset that uses triangulation between the known geographic coordinates of the base station through which the communication takes place.

Introduction

Even after 4-5 years after UMTS licences being issued, UMTS still didn’t spread all over the world and is yet to become the heart of people.There are continuing delays in network installation/launching from licence holders. The mobile network operators can not leave their optimisms about the success of UMTS in providing insane data speeds for full movie downloads and other stuff in the form of 3G mobiles (the third generation mobiles) but there are other things the end user should look at. Lets discuss some factors.

High Speed

UMTS has the ability to provide data rates upto 2 Mbps. This is maximum if we compare it with other 2G and 2.5G networks. This would in turn bring features such as video conferencing, real time streaming and other high bandwidth applications into reality. Furthermore, Bearer services have different QoS (Quality Of Service) parameters for maximum transfer delay, delay variation and bit error rate.

Introduction

Since a couple of years, a debate has been going-on that WLAN (wireless local area network) technology has the pottential to compete with 3G. In my opinion, all this is true from a theoretical perspective but things are quite different if one considers practical implications, lets discuss.

WLAN Advantages over UMTS

Introduction

UMTS networks are emerging in various parts of the world. These networks supports high bandwidth and features like video call. Effects of the new UMTS network on the heath because of electromagnetic radiations need to be studied. This includes both UMTS stations and UMTS phones.

Radiations in the UMTS network

One could be glad to know that UMTS is using a better technology to encode data over radio signal with a combination of small cell size of UMTS network.

Introduction

The basic theme of UMTS revolves around providing extensive features such as video call, high bandwidth rather than just voice calls and short text messaging on GSM cellphones. According to a rough estimate, around 125 billion dollars are being spent by operators in Europe to buy UMTS licences. Because of this and other cost issues discussed below, some analysts think that this huge investment might be risky !
