Abstract Since the internet invention, modem as evolved tremendously and impacted lives globally. Modems transmit digital information over a telephone line by converting it into electrical signals and demodulate it at the receiver via another modem. Based on the amount of data a modem can transmit per unit of time, typically bits per seconds, they are classified. In next section of this paper, it will examine namely 3G and 4G LTE modem technology compare the latter in light to multiplexing and error correction when transmitting and exchanging data via the internet. Further ahead, and the paper will compare encoding ...

The monitoring of the Gigabit Passive Optical Networks (GPONs) is based on the optical coding (OC) technique and which is the most cost-effective monitoring technique. The performance of the OC technique relies on the design of the implemented hardware and on the design of the address code chosen. With an increasing number of GPON users, the address code selected must has the ability to support a number of code-words that are equal or larger than the available users. The main purpose for this research is to improve the GPON monitoring system using the OC technique. This research has developed ...

Introduction

Networking has been enhanced with the introduction of techniques to enhance the techniques that have been used in the networks. The process of communication in various channels undergoes a long process. This paper will focus on the multiplexing and how it enhances communication. It has a role it plays in networking (Abrams, 2004). The term multiplexing as refers to the process of converting many data communication lines or signals into a single data communication line or signal for transmission (www.computing.net) the main aim is to optimize utilization of the transmission channels given that several users share the same channel (Stallings, 2009). ...

Chronologically from the first generation of telephony (1G) that carried only analog voice data, to the current fourth generation (4G) of mobile technology, telecommunications have evolved over the years to cater for the growing networking demands of present day mobile communications users. Each generation has been developed building upon the previous technology to improve on it in order to deliver better services. The generations (G) specify the classes of technology, each having its own data rates and devices associated with it. - EVOLUTION OF MOBILE COMMUNICATION NETWORKS The 1G cellular networks started in the early 1980s and ...

Multiplexing is a method of transmitting multiple analog or digital data signals by combining them into one signal using a single physical medium. The single medium relays the data in high-speed. A multiplexer is the device that is used to combines the multiple low-speed signals and puts them in the high-speed channel. Another device called a DE multiplexer then separates the high-speed signal and extracts the original channels on the receiver side. The reason for multiplexing is mainly to share the high-speed channel which is usually expensive but faster and very efficient. Multiplexing originated with telegraphs and is commonly used ...
