wifi provides 3g speed in 2g areas

Sir,
i have a doubt that
" wifi provides 3g speed on areas where 3g is not present but 2g is present "

It is not very clear what you are asking...
WiFi is Ethernet technology. 2G/3G are cell-phone technologies.
By their design, WiFi is faster than both 2G/3G, but is depends where the "other end" of WiFi is connected to.
