Symmetrically, on both sides of the road, s = 20m wide, there are WiFi masts transmitting at 2.4 GHz. The antennas are 5m high and d=200m apart. Do 4 m high trucks driving on the the meadle of the road affect the transmission quality? Calculate the lowest distance of the truck roof from the border of the first Fressnel zone in metres. If the roof is out the zone put down the positive numers. If it is inside - negative. (Speed of WiFi signal 300000 km/s). H-h=1m
