NEC Corp has announced that it is upgrading microwave links on behalf of fixed and mobile operator Tanzania Telecommunications Company Limited (TTCL), connecting six key rural and island locations in the country to double mobile network capacity and meet demand from local citizens, enterprises and tourists. The USD1.6 million deal is designed to support rising mobile broadband usage and sustainable development in Tanzania, and comes in the wake of a recent government initiative to connect the route from Dar es Salaam, the main economic centre of the country, to the island resort of Zanzibar. Further connections are now planned to run from Shinyanga to Maswa in the north and Mikumi to Kidatu in southern Tanzania.
Under the upgrade, TTCL is using NEC’s iPASOLINK 400, 1000 and 5000iPS solutions which support a hybrid Time Division Multiplexing (TDM) and IP-based mobile backhaul service. This enables the operator to continue to leverage investments in existing legacy TDM systems for voice traffic and use high speed, high capacity Ethernet for data with the option of transitioning to an all-IP network to enable highly efficient long-haul transmissions in the future, the vendor said. The solution can also support the expansion of Long Term Evolution (LTE) when required with minimal capacity upgrades, it noted. State-backed TTCL currently provides voice and data communication services to over 300,000 business and residential customers in Tanzania.
