How to transfer files using Wireless LAN (WLAN / hosted network)

How to transfer files using Wireless LAN (WLAN / hosted network)

Communicate is a process that transfer information from source or server to receiver across a media. This media called transmission media. There are two kinds of transmission media base of the material used. these are wire and wireless.

In a wire connection such as RJ-45, using this cable you have to connecting the sender and receiver using it. Range of transmission are will be as long as the wire, and also more wire needed to connect on multiple receiver or source. This is the primitive one but in some case will be effective one. And now we are commonly use wireless connection which have more efficiency and surely less cost. Using wireless connection will improve the range of transmission area based on gain level of source antenna, and receiver antenna. And other advantage also for some receivers just need to add more antenna and connect to same network.

Sharing is a type of communication, because it sending some datas and informations to receiver. In this tutorial i will talk about how to make a windows files sharing and transfer using a Wireless LAN.(WLAN).

You need to prepare a computer that support hosted network. Because we have to create an Ad Hoc connection first.

To check your hosted network is available yet, just type this command on cmd
netsh wlan show driver
and then see on that red square.

For how to create ad hoc or wireless lan connection click on this link  or you can use a simple apps to create hosted network

And next.. set up our network discovery.

Go to Control Panel - Network and Internet - Network and sharing center - and click on change advance sharing settings

Set up in your computer as the following image (windows 10 other windows version can be a little different but exactly same)

Set up this setting on both receiver and sender computer, so it can be connected each other.

Next we should set the shared folder at sender computer.
Just right click on a folder - properties and ...

Click share

 click share

 just wait some minutes, depend on your folder size

DONE

see the folder now be shared

And now, from the receiver (should connect in same network with sender) go to windows explorer (press WIN + E) and click on network.

You will see your computer name and name of sender computer. Just click on sender computer and click on the folder. And last you are able to copy/cut and paste.

END-joy ^^

Modulation and kinds of modulation

Hello all.. good morning or afternoon or night whatever you read this post, (lol)

Now i will explain about a basic knowledge of networking that called Modulation. What is modulation and what kind of type modulation, i will describe it as far as i can.

Let we start about a sample analogy.

Think about your lecturer sound, when he/she talk there are something different when you are in front of the class and behind the class. While you are in front, you will hear his/her sound well but while you are in behind of the class, the sound will be smaller and get some trouble than it. The trouble is called  noise.

Now lets think again.. While your lecturer use speaker while talk, his/her sound will heard better from behind the class than before. This is in same case with modulation.

The information that you send without modulation have smaller range than after modulation. But why??

Here is the answer, in modulation the information signal will be transmitted and overlapped with carrier signal. Carrier signal make a better range because it has more high frequency. Higher the frequency will give a larger area that affected.

So we get the conclusion that Modulation is a process that make information signal to overlapped with carrier signal which is have higher frequency.

Base on the information signal type modulation can be differentiated about 2 kinds:
1. Analog Modulationn
2. Digital modulation

The analog modulation, can be differentiated about some kinds:
1. AM (Amplitude Modulation)
2. FM (Frequency Modulation)
3. PM (Phase Modulation)

The digital modulation, can be differentiated about some kinds:
1. ASK (Amplitude Shift Keying)
2. FSK (Frequency Shift Keying)
3. PSK (Phase Shift Keying)

Detail about that kinds of modulation will be available in next post.
