3 - Where Do We Come From? CAMTEL s global context Predominantly copper in the access network Copper technology around the decrease stage of its life cycle Major changes in the telecommunications environment of Cameroon (998) Market opened for competition with two mobile operators (999) Internet service provisioning is fully liberalized (both IAP and ISP) Camtel is created in 999 as a 00% owned state company (historical operator) and immediately put to the market (privatisation). 7 years after the privatisation process is still on. Dilapidated and outdated infrastructure Services offered are essentially those carried by copper lines No or insignificant infrastructure renewal Constant loss of revenues (High OPEX due to infrastructure aging, static copper based offer vs. dynamic range of services required by the demand) CDMA Development in Cameroon 3

4 - Where Do We Come From? Life cycle of CAMTEL copper access network Introduction High growth Maturity Decline Service Growth 2005* *Timid takeoff due to : -Succesful clean up operation of access network mainly in Yaoundé and Douala 2-Several completed low scale copper extension projects 3-Effective introduction of ISDN and ADSL services Time CDMA Development in Cameroon 4

5 - Where Do We Come From? Wireless Swipes Fixed Base From ITU data, the number of wireless subscribers overtook that of fixed Network in 2002.This turning point was reached much earlier in Cameroon The number of wireless subscribers increases much faster than that of the fixed network. In Cameroon the ratio is much less than one fixed subscriber for 0 mobiles. Yet the most important part of the global demand remain unsatisfied. The fast spreading wireless subscribers base has diverted huge traffic from traditional PSTN. This erosion of traffic has caused a constant slash of CAMTEL s revenue. CDMA Development in Cameroon 5
