Wifi hotspot

A hotspot is a site that offers Internet access over a wireless local area network (WLAN) through the use of a router connected to a link to an Internet service provider. Hotspots typically use Wi-Fi technology.
The public can use a laptop or other suitable portable device to access the wireless connection provided.
For venues that have broadband Internet access, offering wireless access is as simple as configuring one access point (AP), in conjunction with a router and connecting the AP to the Internet connection. A single wireless router combining these functions may suffice.

^Security 

Security is a serious concern in connection with Hotspots. 
There are three possible attack vectors. 

• First, there is the wireless connection between the client and the access point. This needs to be encrypted, so that the connection cannot be eavesdropped or attacked by a man-in-the-middle-attack. 
• Second, there is the Hotspot itself. The WLAN encryption ends at the interface, then travels its network stack unencrypted and then travels over the wired connection up to the BRAS of the ISP. 
• Third, there is the connection from the Access Point to the BRAS (Broadband Remote Access Service) of the ISP (Internet Service Provider).

The safest method when accessing the Internet over an Hotspot, with unknown security measures, is end-to-end encryption. Examples of strong end-to-end encryption are HTTPS and SSH (Secure shell).

Types

 Free hotspot operates in following ways:

• Using an open public network is the easiest way to create a free HotSpot. All that is needed is a Wi-Fi router.
• Closed public networks use a HotSpot Management System to control the HotSpot. This software runs on the router itself. With this software, operators can authorize only specific users to access the Internet.

Hotspots are found at restaurants, train stations, airports, libraries, hotels, hospitals, coffee shops, bookstores, fuel stations, department stores, supermarkets, parks, public pay phones, and other public places. Many universities and schools have wireless networks in their campus.

Some cheapest solutions for your wifi antenna accelerator

Just arrange these items which will help you to made cheap wifi accelerator antenna.

1. A USB wifi modem,
2. Aluminum foil,
3. Antenna holder,
4. USB extension cable.

Making of steps:

• The Reflector:

First of all we have a problem to making a reflector.I have found some pre-made template on the internet, for that download the template and just fit on your cardboard.When you download the template just cut it into shape.I am using a plastic file's case you may use an cardboard also to get the cheapest solution one.that you cut a square hole in the middle of the cardboard to fit an wireless usb adapter.

• Covering with aluminum foil:

Once you get the template ready.Just go to the kitchen and Grab an aluminum foil. Atleast you may ask for permission from your mom first.Cover it with aluminum foil using an ordinary glue.

 

• Antenna holder:

 

 

Use any materiel for holding your antenna.It is very easy just take a stick or some another item.I have used a wooden stick and just stick it on the back surface of the reflector.You can use a nut or some strong glue which you have to buy from market.

 

• Setting:

 

 

Now just set up the wireless modem inside the center of the reflector as shown in the diagram.Than give it the correct position and direction to check up in which direction the speed get boosted than adjust that position in which you will get the maximum speed than just fix it on that direction carefully.  

 

And thats all your cheapest antenna is ready to use. 

Prevent the Unwanted Users And Reduce your traffic that can Accelerate your Wifi Network

You can now boost up your wifi signal to avoid unwanted users.This technique is presented to you by our famous company macintos. This mac address filter is very effective and very secured technique  to stop the unwanted users.These are commonly use in many institutes and companies to keep checking the unwanted users under their wifi range and also to stop them.

It is a also very effective because it allows only a limited users to pass through the check gateway to the network. So you can include the mac address Of all the computer which is used by you and your known person to get easy access.

How to use MAC address filter : 

This feature can be use by opening of your wifi router.As all the routers are not same.So kindly use your router manual for details.In general you will have to enable the feature of mac address filtering and add the mac address to those computer in which you want the network.

Limitations:

Like other technologies even this is not fully secured from the hackers because the trick to spooring the mac technology can easily be implemented and you can also get the check gateway of the protected network. It may be a safe technology but the hackers are still keep improving themself to access your network.

Advantages:

Increases the security of the wifi network and also its access.

No unwanted users on your network.

It will grow up the speed  of your wifi because of no unwanted users in your network.

Accelerate your wifi using a parabolic stainless steel net

This is an unbelievable Content to boost up your wifi hub.Let Start to make a  wifi accelerator.

First of all start gather your content which will be used.I will give u promise to set a cheapest solution during this promise i will suggest u cheapest products too.You can use any wifi adapter,a simple communicate cable,and an net which is in parabolic in shape.
First of all make an enough hole by which we can put the wifi adapter through it and than rotate it along a  particular direction in air.when you see that there will be grow up your speed in a particular direction.After that just fix it with some item.stay safe during this process use proper safety to do your job properly.

 I will use a simple and study trick which says that when we use an parabolic net than it will attract an large range of frequency because the strainer attract an large amount of frequency than pass it to the wifi hub which is inside it and the center of strainer.Because of according to the shape of the net the principle says about parabola that a maximum amount of rays falls on it when it is pass through air or the atmosphere.it attracts a maximum no. due this reason i will suggest you to use only parabolic shape net. It will help you to boost your wifi adapter.This is a simple less expensive and also easy to use product.

 Safety:-

This is a home made process due to this u can use an rubber hand gloves ,safety scissor,and ordinary tape.

Use palstic sandle during work because with this you can safe or less harm when electric shock will attracts you during process.

Making a home made wifi booster

Now you can made a WiFi booster at home and not with some expensive part.It can just made with the help of waste material just like an aluminum foil and only with two techniques and those techniques help us to boost up the signals of your wifi in a particular direction.let us discuss about the two techniques below.

Accelerate Wifi Using softdrink container:-

Let us make an wifi accelerator using aluminum foil or an softdrink container.First of all let first make a cylinder out of square cut the container by folding it which is hollow from inside and open at both ends now paste or attach it to a clipboard horizontally in the center of the cylinder. Now just bend the clipboard and make it like a parabola and a punch hole on the surface of the material  so that antenna of your wifi router can pass through it.Than leave it as it is than the signal of the wifi router will be more focused toward the opening of the cylinder this causes 40-50% increase in strength.Just do it and it really works.this is also easy and simple useable product. 


Accelerate  WiFi Using A Drink Can:-

You can't imagine that to making a wifi accelerator is just with the help of a soft drink can.It is a very easy for everyone also .First of all take any soft drink can which is hollow inside.now make a hole in its bottom side and upper side is opened the hollow is made up to cross the antenna through it.now start your wifi router than you will see that your wifi is speed up upto 30-40% make sure that the the can will be unscratchable and when you turn around everywhere than you will find that your actual speed is much more grow up than after you make an attachment of an simple and easy soft drink can.Just do it and enjoy with your growing speed.this is an less effective than the previous one due to this effect i will suggest you to use the softdrink container rather than that.

Precautions:

Use safety scissor when cutting the cylinder.

Beware of electric shock it can harm your body uses plastic sandle to safe from it.

make all connection tightly and check than that

Expand your wifi network range

Addition of more than one account

You can now add more than one access point. Businesses places requires more than one AP's, but typically residences requires only one AP, but sometimes large houses requires more than one AP's then you have to add your primary wireless router to the second one with the help of an Ethernet cable.

 Ethernet was originally based on the idea of computers communicating over a shared coaxial cable acting as a broadcast transmission medium. Ethernet's shared coaxial cable traversed a building or campus to every attached machine. A scheme known as carrier sense multiple access with collision detection governed the way the computers shared the channel.

Network repeater

A network repeater is a device used to expand the boundaries of a wireless local areanetwork. In the past, wired repeaters were used to join segments of Ethernet cable. Modern Ethernet networks use more sophisticated switching devices, leaving the wireless flavor of the network repeater a more popular device for use with wireless LAN at work and home. WLAN offer tremendous convenience, but a drawback of these systems is the limited area covered by wireless signals. Obstructions and other common electronic devices interfere with and degrade signal strength. This can make it difficult to connect from a basement, back room, or upstairs office, depending on placement of the wireless router and other variables. So we use network repeater for this problem. A WiFi repeater will pick up the signal from a wireless router and amplify it, propagating signal strength to boost the distance and coverage of the WLAN.
