Abstract :
The paper describes the cellular coverage system design and implementation for the Rio de Janeiro Metropolitan underground transport system. The project was developed at WiNGS Telecom and implemented by a pool of companies for Algar Telecomunicac$80o˜es Leste (ATL), the B-band operator in Rio de Janeiro, Brazil. The project characteristics, assumptions made and chosen solutions are described, as well as the propagation models and measurements. The threshold degradation due to the use of several antennas to provide coverage in tunnels and platforms is analyzed and complete link budget equations obtained.
