CAN WE HEAR FROM TECHNOLOGY GURUS WHY ALL THE TELECOMMUNICATION NETWORKS DO GO BAD DURING THE RAINY SEASON? WHAT ARE THE CAUSES?

In Nigeria, mobile service operators do very little or no optimization after deploying their network,
Rainfall also increases call drops and punctuated connectivity.
Some networks are already very choked and performing poor, rain will aggravate the effects of already choked networks.
Sometimes this happens where the local telecoms infrastructure is already old or badly connected allowing water to get into the equipment and change the electrical properties thereby causing a change in performance and in some cases causing a short of certain lines, reducing the total bandwidths.
In microwave communication there is a phenomenon know as Rain fade which refers primarily to the absorption of a microwave radio frequency (RF) signal by atmospheric rain, snow, or ice, and losses which are especially prevalent at frequencies above 11 GHz. It also refers to the degradation of a signal caused by the electromagnetic interference of the leading edge of a storm front. Rain fade can be caused by precipitation at the uplink or downlink location. It does not need to be raining at a location for it to be affected by rain fade, as the signal may pass through precipitation many miles away, especially if the satellite dish has a low look angle. From 5% to 20% of rain fade or satellite signal attenuation may also be caused by rain, snow, or ice on the uplink or downlink antenna reflector, radome or feed horn. Rain fade is not limited to satellite uplinks or downlinks, as it can also affect terrestrial point-to-point microwave links (those on the earth's surface).
