heal.abstract	The use of millimetre waves at 25 and 40 GHz for wireless communications appears to be a favourable choice as it provides sufficient bandwidth to support broadband services and high data rates. This paper intends to present issues arising in the design of systems operating at millimetre region. Transmitter and receiver height variation found to influence significantly the area coverage. Rain attenuation reduces the available system margin according to the required availability. Real time measurements showed that the rainfall rate does not exceed 39mm/hr. Maximum gas attenuation is found 0.25dB at 25 GHz and 0.18dB at 40 GHz derived also from real time measurements.	en
