By Paul Noumba Um, Laurent Gille, Lucile Simon, Christophe Rudelle

The liberalization of the telecommunications markets in Sub-Saharan Africa resulted in elevated festival at the provision and pricing of verbal exchange prone. yet, end result of the loss of acceptable regulatory instruments, newly verified regulators are poorly outfitted to arbitrate expanding interconnection disputes among competing operators.

The proposed expense version takes under consideration so much positive factors characterizing the improvement level of telecommunications networks in Sub-Saharan Africa (small measurement of mounted community, significance of rural telephony, over the top reliance on microwave expertise, explosive call for for cellular carrier, and vulnerable regulatory capacity). 'A version for Calculating Interconnection charges in Telecommunications' deals telecom regulators and operators not just a choice help software but additionally a stimulant to augment an realizing of the common sense of regulating a area open to pageant.

The networks still reflect choices of technology made in the 1990s. The scope of inefficiencies resulting from this technology legacy is rather great. • To reach remote rural areas, subscriber concentration systems (TDMAs) are installed. These systems serve from 8 to 256 subscribers and use time division multiplexing technology, known as TDMA. 19 • Fiber-optic systems are not yet massively rolled out. In many cases, the demand does not justify the rollout of broadband transmission systems; however, more and more operators are beginning to replace their microwave transmission links with fiber-optic cables.

Four sheets specific to mobile networks (whose results appear on the general results sheet). • One sheet on the sensitivity of the model to some parameters. • Three specific management sheets (two sheets for the publication of fixed and mobile reports and a • The model then aggregates network elements costs. • The model finally calculates the interconnection costs, depending on what network elements are used to supply the service. The network is made of network elements. Any communication or any interconnection service (which is a special form of communication) uses, on average, x times each of these elements (with x varying from 0 to a few units at a maximum).
