I need to transmit status of some digital I/Os and some analog data at a distance of approx 2km.

can any one please suggest the required hardware ?

urgent please.

Hello

in this case you can use the TIA Selection Tool. In this Tool, there´s a calculation of IWLAN, if the chosen antenna and SCALANCE W suffice for your distance.
