how to increase WIFI's range

Hi experts ,
how to increase the WIFI,s range
What is the maximum range ?
Can i buy any module to increase it ?
or can i build any circuit for this purpose ?
please help me

thanks

A simple solution is a better antenna with higher gain, very easy to construct
Biquad Antenna Construction
The radiation pattern is wide but still limited is an angle in front of the antenna

Here is some ideas....................

I have used sometimes postcard sized al-plate formatted only
2-D paraboloid back my wlan-stick. Works nice.

Old small satellite antenna dish gives lot of amplification.

anybody tell me ,what is the maximum coverage or range of wifi.

Band Range:
a= indoor 35m outdoor 120m
b= 38m 140m
g= 38m 140m
n= 70m 250m

In most standard Wi-Fi routers, the three standards, a, b and g, are enough. But in long-range Wi-Fi, special technologies are used to get the most out of a Wi-Fi connection. The 802.11-2007 standard adds 10 MHz and 5 MHz OFDM modes to the 802.11a standard, and extend the time of cyclic prefix protection from 0.8 µs to 3.2 µs, quadrupling the multipath distortion protection. Some commonly available 802.11a/g chipsets support the OFDM 'half-clocking' and 'quarter-clocking' that is in the 2007 standard, and 4.9 GHz and 5.0 GHz products are available with 10 MHz and 5 MHz channel bandwidths. It is likely that some 802.11n D.20 chipsets will also support 'half-clocking' for use in 10 MHz channel bandwidths, and at double the range of the 802.11n standard. All links pass over tidal waters; they range in length from 2.5 km to 19 km..

both alexan and kak111 mentioned the technique but you only get some help with it for long range its all other thing.

What is the maximum range ?

Click to expand...

these are the ranges depending on your module band
a= indoor 35m outdoor 120m
b= 38m 140m
g= 38m 140m
n= 70m 250m

Can i buy any module to increase it ?

yes you can, but i will rather good to change he setup.

or can i build any circuit for this purpose ?

Click to expand...

it is though possible but i thing buying a whole module and setup will be more satisfiable.

If you use a high gain antenna or a amplifier for WLAN you have to make sure that you have not too much gain (exactly speaking not too much ERP) because there are strict regulations in the max ERP.

Do a google for 'Windsurfer'; or try **broken link removed**
