Isha Ambani, daughter of Mukesh Ambani , Chairman and Managing Director of Reliance Industries, today unveiled what could revolutionise Indian telecom sector. Addressing at the Reliance Industries ' 41st annual general meeting today at Birla Matushri Sabhagar in Mumbai, she announced the launch of JioGigaFibre, the optical fibre-based broadband service.The company will extend fibre connectivity to homes, merchants and SMEs. 1,100 cities will offer most advanced fibre-based broadband connectivity solutions. Two of the main features of JioGigaFibre will be smart home technology and TV calling. JioGigaFiber broadband will come with a set-top box for TV. It will have enabled voice command feature on TV.JioGigaFibre will be based on Fiber to the home (FTTH) technology. It is expected to disrupt the segment of home broadband services now. Reliance is likely to offer an attractive combo of fast broadband connectivity at initial data speeds of 100 Mbps (with huge dollops of free data thrown in).FTTH, as the name suggests, means installing the fiber cable right up to the individual building. At present, the fiber cable reaches only till the main premises while the last connections to individual homes/offices are through traditional copper cable.The cable used for connections to individual units is not made of fibre. The traditional cable is not as efficient as the fiber cable. Due to patches, etc, the traditional cable is slower. A fiber cable till the individual unit dramatically increases speed and quality and improves the experience of surfing, gaming and streaming, etc. FTTH could be 100 times faster than the traditional modem connections. FTTH is also costlier than the traditional cable.No. Bharat Sanchar Nigam Ltd (BSNL) already offers FTTH broadband schemes in Kolkata and Chennai. However, Jio's entry in FTTH will at a much bigger scale and more aggressive. Jio is running a pilot in many cities.An aggressive FTTH service launch by Jio can cause two sets of disruptions, according to Rohan Dhamija, partner & head for India, South Asia & Middle East at Analysys Mason. First, it can immediately disrupt home broadband pricing, forcing rivals such as Airtel to slash rates. Second, it could also have a secondary impact on the larger mobile services market, if Jiochooses to bundle generous wired broadband packs with its current 4G plans.
