Thousands of households in Maputo, the capital city of Mozambique, on the African continent, can now enjoy Digital TV and Internet access thanks to a new Digital MMDS System integrated with a Wireless Internet System. The integrated system consists of a Base Station and subscriber equipment.
A Cable AML Indoor, 200 Watt Transceiver at the base station transmits digital data carriers from an existing Cable TV headend nearby. The transmitter output is routed to a 200 foot transmission line that feeds an omnidirectional antenna mounted at a height of 180 feet at the top of a transmission tower. The MMDS system transmits five digital PAL B/G DVB carriers, or a total of 40 TV programs modulated with 64-QAM. The DOCSIS wireless downstream carrier is also modulated at 64 QAM
Customers use either Downconverters or Transceivers. Downconverters accommodate TV-only reception while Transceivers deliver TV plus Internet service simultaneously. According to Humberto Barros, “The commissioning of this system is giving us the capability of substantially expanding the service footprint to areas previously not accessible to us.”
