Cascade systems are based on the Teko Telecom Off-Air Repeater connected via leaky cable to Bi-Directional Amplifiers.
The Repeater interfaces itself with BTS on one side, while it feeds the first part of the leaky cable on the other side.
Bi-Directional Amplifiers extend coverage to the entire length of the shadow areas, compensating the attenuation introduced by radiating/coaxial cables.
Bi-Directional Amplifiers are powered and managed by Off-Air Repeaters via leaky cable.
The whole system can be managed locally (at Off-air repeater side) or remotely via wireless modem.
