Point to Point Wireless Communication.

Point to point communication means one point can be connected to only one another point.  At microwave frequencies at least 60% of the first Fresnel zone must be clear for good signal strength .

The device has to selected according to the link distance and data rate that is required.

As per the device specification if it is FDD we require two different frequencies for one point to point link , we have to configure the device  ( Radio ) with one uplink and one downlink frequency ,  It has to be configured on both the devices ( Radios ) so that communication can take place over those frequencies.

Another configuration is SSID ( System identifier) , SSID must be same on both the radios , IP must be configured so that reachability can be checked and also so that we can access the radio and tehre are some other configuration that varied from radio to radio.

If the device is TDD then same frequency must be configured on both the devices and both the radios must have same SSID, same channel channel bandwidth , rest of the confiduration depends on radio to radio .
Again the radio must be provided with IP so that it can accessed and reachability can be checked .

The range ( Distance of point to point link ) and data rate depends on antenna parameters.
