I am going to set up a wLAN where there are 4 data collecting instruments (A, B, C, D shown in the plot) in a mountain. Two neighbor nodes are 10km line-of-sight distance away from each other as shown in the attached plot. Point D communicates with server (point E), which is 60km away.

/ \ 60KM
A D----------E
\ /

My plan is to set up three Cisco wireless APs in the A, B, C points, two Cisco 1310 wireless bridges at D, E points, and one amplifier at D or E to reach 60km transmission distance. But I haven’t found any AP with range around 10km. Shall I use Cisco 1310 wireless bridge at A,B and C or use AP with amplifer? I know somebody has achieved more than 10km range by only access point and amplifier with other brand equipments. Can I add amplifiers at any Cisco APs to get over 10km range if I choose the lowest data rate?
I also have another question about Cisco antenna. I only found information about antenna ranges at 11Mbps data rate and 54Mbps. Is there any information of antenna range at 1Mbps?
Thanks for reading my questions.
