Qtel has invested 600 million Qatari Riyals to upgrade Qatar's infrastructure with fiber optic cables, which transmit data 100 times faster than other cables and can carry signals over longer distances. The company is laying underwater fiber optic cables between Qatar and India to connect Qatar to the world, and will provide ultra-fast broadband internet and high definition TV to customers over the next 18 months as they lay cables across the country area by area.
