Different types of networks

Different types of (private) networks are distinguished based on their size (in terms of the number of machines), their data transfer speed, and their reach. Private networks are networks that belong to a single organization. There are usually said to be three categories of networks:

• LAN (local area network)
• MAN (metropolitan area network)
• WAN (wide area network)

• Summary.

Network Types:

Communications networks differ in geographical size. Networks may be constructed within a building or across several buildings. Networks may also be citywide and even international, using both cable and air connections. There are three major network types: LAN (local area networks), MAN (metropolitan area networks), and WAN (wide area networks).

• Summary.

Network Operating System

A Network Operating System (NOS) is a software program that controls other software and hardware 

running on a network. It also allows multiple computers, known as network computers, to communicate with one central hub and each other to share resources, run applications, and send messages. Such a system can consist of a wireless network, Local Area Network (LAN), or even two or three computer networks connected together. Administrators running these networks typically have training in different network operating systems.

Network-Based Wireless Location

 Introduction:

This lesson provide to trainees more information for Network-Based Wireless Location to help the trainees Improve knowledge.

Objectives:

• Network-based wireless location finding.
• Summary.

Network-Based Wireless Location
Network-based wireless location poses several interesting problems from a signal processing perspective. The estimation algorithms must provide accurate parameter estimates under challenging conditions such as fast fading channels, low SNR, multipath effects, and multiuser interference. Small errors in estimation can lead to large errors in location.To get more information please DOWNLOAD the PDF by click over address link or picture.
