ITT :: Mesh Network with WiFi And WiMAX

Posted by MUBEEN AHMED , , 02:31

Mesh Network with WiFi And WiMAX


Mesh topology is not supported by existing IEEE's wireless LAN standards but it becomes popular as city-wide (municipal) Wi-Fi network deployment gains more supporters day after day. In a mesh network, each node (i.e. base station or access point) connects to several neighboring nodes and on to a mesh gateway (i.e. a base station that aggregates the mesh network traffic and routes it to the Internet). Since each node has many routes to a mesh gateway, mesh network is very reliable. But mesh network is more complex to manage and poses interference challenge especially for operation in a license-exempt band such as in Wi-Fi case.
WiMAX access, transport, and backhaul in a municipal Wi-Fi mesh network
Figure. Mesh Network with Wi-Fi and/or WiMAX
WiMAX can work on all layers of a municipal mesh network (hotzone/metro zone).
By examining current Wi-Fi mesh network architecture, basically there are three layers. These are mesh access handling user access to a mesh node, mesh transport interconnecting mesh nodes and routing traffic to mesh gateways, and backhaul connecting a mesh gateway to an Internet PoP (Point of Presence) or other content gateways.
Backhauls for mesh Wi-Fi networks are provided using various wired and wireless solutions, i.e. fiber optic, leased line, DSL, and proprietary point-to-point (PTP) or point-to-multipoint (PMP) radio including some pre-WiMAX equipment. A wireless backhaul - specifically WiMAX - enables flexible placement of a mesh gateway node anywhere in the network, therefore it doesn't have to be located in a telco's CO or close to a fiber/DSL termination point. The portable WiMAX equipment (Base Station) also allows fast installation and easy relocation. Moreover, WiMAX was designed for outstanding performance in NLOS environment, typical in metro area with many high rise buildings. WiMAX also can operate either on licensed or unlicensed band, giving more options for operator/ISP/municipality in addressing various interference conditions and users' requirements.
The mesh transport layer provides the interconnection between mesh nodes. There is a project in the IEEE to standardize Wi-Fi as an intra-mesh transport solution, but the work is still in progress. The current established Wi-Fi solution uses proprietary technology developed by each vendor which might cause interoperability issues in the future. WiMAX can naturally replace Wi-Fi in this layer, interconnecting mesh nodes using standard equipment based on the IEEE 802.16-2004 or 802.16e which includes support for optional mesh topology. Besides, WiMAX has built-in QoS support and is optimized for longer distance (WiMAX is a wireless MAN while Wi-Fi is a wireless LAN) .
For mesh access layer, at present users connect using their Wi-Fi-enabled laptops, PDAs, or smart phones. WiMAX integration into such portable/mobile devices is still in its early stage of development. However, in several months/years to come one may expect the emergence of dual-mode Wi-Fi/WiMAX devices and network adapters (NIC, PC card, PCI Express) which can connect automatically to any available network with the best signal.

ITT :: PPPOE connection on Windows 2000

Posted by MUBEEN AHMED , , 01:18

Learn How To Make PPPOE Connection In Windows2000

The first step is to DOWNLOAD RASPPPoE. You can do this with your alternative backup dialup service if you don't have an alternate Internet connection. Use the "Download and install" link on the left, and you'll want to download the version marked "32-bit release for x86 machines". Once you've completed the download, unzip the file into a temporary directory (such as C:\RASPPPoE).
Click "Start" then "Settings" then "Control Panel", then browse to "Network and Dial-Up Connections"

Download Patch:
http://www.raspppoe.com/files/RASPPPOE_098B.ZIP
http://www.raspppoe.com/files/RASPPPOE_098B_3COM.ZIP


 
Right-click "Local Area Connection" and select "Properties".


 
In the properties dialogue box, click the "Install" button.


 
In the "Select Network Component Type" window, select "Protocol" and click the "Add" button.

 
In the "Select Network Protocol" window, click the "Have Disk" button.
In the "Install From Disk" window, either type the name of the temporary directory to which you extracted RasPPPoE, or click the "Browse" button to navigate to it, and then click the "OK" button.
A new window opens, offering the "PPP over Ethernet Protocol" for installation. Click "OK" to start installing the protocol.

 
After the "PPP over Ethernet Protocol" is installed, return to the "Local Area Connection Properties" window and click "Close" to close the window. The protocol is now fully functional, but you still need to create a dialup connection to use it.

 
Click the "Start" button on the taskbar and select "Run" to bring up the "Run" dialogue box. Type raspppoe into the box and click the "OK" button to run the dialup Connection Setup application.

 
A dialogue box appears with a combo box labelled "Query available PPP over Ethernet Services through Adapter" at the top.
Select the network adaptor to which your broadband modem is connected from the list. If the protocol is only operating on one network adapter, the box will be greyed out, as there is no choice to make. Click the "Query Available Services" button. The application will send out a query for offered services and display the result in the list view below.
Click the "Create a Dial-Up Connection" for the selected "Adapter button".

 
Shortly afterwards, a shortcut to the new dialup connection named "Connection through (adaptor name)" should show up on your desktop.

 
Rename the connection icon to iiNet ADSL Connection.

 
To start the connection to the Internet, double-click the "iiNet ADSL Connection" icon. If it's the first time you've started the connection, you'll need to fill in the following fields:
  • Username: Enter your full iiNet username, e.g. john.citizen@iinet.net.au
  • Password: Enter your password as supplied by iiNet
Click the "Dial" button to connect to the Internet.

10BaseT & 100BaseT RJ Connectors

When working with 10BaseT and 100BaseT wiring, concentrators, and adapters from different vendors, it is possible to connect everything and get no communication between file servers and workstations. When there are several unknown variables, it is difficult to determine which component is broken.
