The IPv6 emerged as a result of the growth of the internet at an
unprecedented scale along with the depletion of IPv4 addresses. Only when the mobility and multihoming are implemented into the system can the full benefits of the system be reaped. But the need for security in internetworking protocols and the above goals contradict eaxh other. decoupling of and mapping between the identity of the host and its topological location is required by the internetwork consisting of mobile,
multihomed and secure end-points . The Host Identit ....etc

ABSTRACT

A SIM (subscriber Identity Module) is a removable smart card for mobile phones. It contains subscriber information, such as the IMSI (International Mobile Subscriber Identity). It can also be used to store user-defined information such as phonebook entries.
The use of SIM card is mandatory in GSM world. There are two types of SIM operating system – Native and Java card. The SIM card is activated in an environment using five stage process called, authentication process.

The accelerated growth of content-rich applications that demand high bandwidth has changed the nature of information networks. High-speed communication is now an ordinary requirement throughout business, government, academic, and work-at-home environments. High-speed Internet access, telecommuting, and remote LAN access are three services that network access providers clearly must offer. These rapidly growing applications are placing a new level of demand on the telephone infrastructure, in particular, the local loop portion of ....etc

ADSL technology is asymmetric. It allows more bandwidth downstream -from an NSP s central office to customer site - than upstream from the subscriber to the central office. This asymmetry, companied with always-on access (which eliminates call setup), makes ADSL ideal for Internet/intranet surfing, video- on -demand, and remote LAN access. Uses of this application typically download much more information than they send. ADSL transmits more than 6 Mbps to a subscriber, and as much as 640Kbps more in both directions. Such rate expands existing ac ....etc

Asymmetrical Digital Subscriber Line

1.Links subscriber and internet service provider only for residential users.

2.Uses existing local loops.

3.Uses currently installed twisted pair cable.

4.Can carry broader spectrum of 1MHz or more.

ADSL CONFIGURATION

The twisted pair local loop is actually capable of handling bandwidths up to 1.1Mhz, but the filter installed at the end office of the telephone company where each local loop terminates limits the bandwidth to 4Khz(for voice comm.). If the filter is removed the entire 1.1Mhz i ....etc

Positioning a Mobile Subscriber in a Cellular Network System based on Signal Strength




INTRODUCTION

In positioning a mobile subscriber (Location
Tracking), a mobile user is provided with
information pertaining to its current position. It
is one of the popular areas of wireless
computing research. Researchers paid attention
to Positioning Systems after the Federal
Communications Commission (FCC), mandated
that all wireless carriers in the United Stat ....etc
