### Acquisition System
However, these regions are not covered in their entirety, except for the region << Le Centre>>. The CMLs concerned are those currently available for the cities of Ouagadougou, Bobo-Dioulasso, Banfora, Koudougou, Ouahigouya, and Kaya, plus those on the Telecel Faso's backbones. Mobile phone operator Telecel Faso uses two types of links: urban connections and intercity connections. Urban links are used within cities such as Ouagadougou, Bobo-Dioulasso, Banfora, Koudougou, Ouahigouya, Kaya, etc. Those links are short distance ones--from a few hundred meters to 10 km--transmitting on frequencies in the range between 10 GHz and 15 GHz. Intercity connections are long-distance links--between 10 km and 50 km--transmitting on frequencies in the range between 6 GHz and 9 GHz. They are used to interconnect major cities of Burkina Faso. These include CMLs located on the axes Ouagadougou-Sabou-Boromo-Hounde-Bobo, Dioulasso-Banfora, Ouagadougou-Koudougou, Ouagadougou-Ziniare-Kaya, and Ouagadougou-Gourcy-Ouahigouya. For all links, the antennas all \begin{table}

It should be noted that horizontally polarized links are more sensitive to rain attenuation than vertically polarized ones [27].
