When oil company Andes Petroleum Ecuador (ANDESPETRO) needed to deliver guaranteed telecommunications connectivity between two points over 100 kilometres apart, they selected 4RF Communications and the Aprisa XE.
The use of sub 3 GHz spectrum overcame the propagation problems encountered in areas of forest, mountains and tropical environments, to provide 99.999% availability, with an E1 and Ethernet communications between the two locations. The main requirement for this application was to deploy a communications solution that would provide a guaranteed E1, G.703 service.
The Aprisa XE in the 1.5 GHz licensed spectrum band was chosen for the challenging long distance link: the use of the low frequency band meant reduced path loss and immunity to the environmental effects that impact higher frequency bands. 4RF and its local partner, DIT Telecomunicaciones, carried out the required path planning to demonstrate that the link could meet both the distance and quality of service requirements.
The 106 km link provides ANDESPETRO with a total capacity of 2872 kbit/s, allocated to an E1 and 784 kbit/s Ethernet. The quality of service has remained at 99.999% availability.
