ant bit pattern called chip sequence whereby an nchip code spreads the signal by
a factor of n If some interference destroys part of the chip sequence the original bit may still be recovered
from the remaining chips

Orthogonal FrequencyDivision Multiplexing OFDM

The general idea of OFDM is to split a highrate data stream into lowerrate streams which are trans
mitted simultaneously over a number of subcarriers These subcarriers are orthogonal to each other in
the sense that when listening to one subcarrier the others don t interfere hence the name Orthog

MOBILE COMPUTING LOCATION MANAGEMENT


Introduction
Managing location information of mobile nodes is an important issue in mobile computing systems. Location management is one of the fundamental issues in cellular networks. It deals with how to track subscribers on the move and how to update his or her movements. In mobile communication environment, they are going to accommodate more subscribers; the size of the cell must be reduced to make more efficient use of the limited frequency spectrum allocation. This will add to the challenge of some fundamental issues in cell..................==> [ Click Here to Read More ]

Mobile Communications Overview
Data Communications have been achieved using a variety of networks such as PSTN, leased-lines and more recently ISDN (Integrated Services Data Network) and ATM (Asynchronous Transfer Mode)/Frame Relay. These networks are partly or totally analogue or digital using technologies such as circuit - switching, packet - switching e.t.c.
Circuit switching implies that data from one user (sender) to another (receiver) has to follow a prespecified path. I..................==> [ Click Here to Read More ]

Flow Control
TinyTP specifies a flow control mechanism based on extended credit; that is, during the setup of a TinyTP connection, each side informs the other of a number of outstanding “credits,” where each credit represents a TinyTP packet that may be sent to the side extending the credit.

ARCHITECTURE, CHALLENGES AND RESEARCH ISSUES ON MOBILE COMPUTING

Abstract

With the advent of the Internet and the plurality and variety of fancy applications it brought with it, the demand for more advanced services on cellular phones increasingly becoming urgent. Unfortunately, so far the introduction of new enabling technologies did not succeed in boosting new services. The adoption of Internet services has shown to be more difficult due to the difference between the Internet and the mobile telecommunication system. The goal of this paper is to examine the characteristics of the mobil..................==> [ Click Here to Read More ]
