hai all,

I would like to design a antenna for wifi 802.11g system with data rate greater than 24Mb/s.

now my Q? is what should be my antenna gain, in order to cover the 50 meter distance.
 

Re: antenna for Wifi

The free-space path loss for this distance and frequency is approximately 75dB.
Including some other extra losses and assuming a -80dBm receiver sensitivity for 24Mb/s, and +18dBm transmitter output power, a 0 dB antenna gain would be fine to get the link.
