since you mentioned my village, it is located 5 km from the central office (cable run, AKA road, not direct distance) in bterram. Assuming the technology in use is ADSL2+
i found the following on the internet somewhere
ADSL2+ Sync rates
Less than 1km should be 23-24Mbit
1.0km = 13.81dB = 23Mbit
1.5km = 20.7dB = 21Mbit
2.0km = 27.6dB = 18Mbit
2.5km = 34.5dB = 13Mbit
3.0km = 41.4dB = 8Mbit
3.5km = 48.3dB = 6Mbit
4.0km = 56dB = 4Mbit
4.5km = 62.1dB = 3Mbit
5.0km = 69dB = 2Mbit
also this graph
and this one
it means that i can only get 2.0mbps with this current fiber penetration. If no fiber is deployed then matra7 ma 5ere shana2ou.
