2. What’s FMC?
“Fixed Mobile Convergence is a transition point in the
telecommunications industry that will finally remove
the distinctions between fixed and mobile networks,
providing a superior experience to customers by
creating seamless services using a combination of fixed
broadband and local access wireless technologies to
meet their needs in homes, offices, other buildings and
on the go”
