The project goal of Telkomsel, a big Cellular operator in Indonesia, was to bring 3G connectivity to a small village from Sambirampak to SeloBanteng at Probolinggo.

Competitors solutions

  • Using microwave solution 7GHz;

    Figure 2

    This Option makes it possible to reach a link between two radios. The main drawback is the necessity of additional repeaters. Although the implementation of extra equipment provides high capacity, it leads to high CAPEX and OPEX.

  • Using a higher Tower;

    Figure 3

    The link communication with the help of an higher tower renders possible the link and needed data transmission. The Disadvantages of this option are very low capacity and very high CAPEX and high OPEX.

Youncta's solution

The best solution is to use Y-HAUL.

Y-Haul is a new generation of UHF/VHF point-to-point wireless communication system. This equipment provides data transmission with a capacity of 30 Mbps and lowest CAPEX & OPEX.

  • Frequency range: 300-700 MHz;
  • QPSK to 64QAM for longer hops and/or increased capacity;
  • Different channel bandwidth: 1.75-12 MHz;
  • Fast Ethernet for Y-Haul TDD and Fast Ethernet plus E1 for Y-Haul FDD Interfaces available.

Y-Haul becomes a very good option to improve the services portfolio for:

  • Backhaul 3G for remote Node B;
  • Carrier class corporate customers;
  • Public services for Government remote zones;
  • NLOS links with high capacity;
  • And many more.

.... avoid high Capex:

  • Using repeaters with microwave regular solution;
  • Using low capacity with UHF low frequencies;
  • Using low capacity with expensive satellite services;
  • And more.

.... avoid high Opex:

  • Using many units to control;
  • Using complex low frequencies to deploy, operate and maintain spare;
  • Using services when you don't have the full control.
