Megacable Pioneers World’s First 256QAM Digital MMDS System

Megacable, Mexico’s largest Cable Operator, has recently converted the analog MMDS system in Ciudad Juarez (Mexico) to a digital MMDS system which is the first operational system in the world transmitting with 256QAM modulation.

The Megacable system is designed to provide increased spectral efficiency so as to package a higher number of TV programs in less spectrum than older systems, thus allowing the simultaneous transmission of analog TV, digital TV and wireless Internet access.

The analog-to-digital MMDS conversion plan was devised and implemented by Megacable’s technical staff and it included a new digital Headend as well as a 1000 Watt broadband dual-redundant transmitter from Cable AML.

According to Ing. Francisco Sandoval of Megacable, “the new system is allowing Megacable to upgrade service to our existing customers as well as adding new ones with expanded channels. We are now planning to add wireless Internet service to our customers, which will give us the option of offering high quality triple-play service.”
