KOLKATA: Remember all those stories about remote-controlled gadgets at home. These have remained dreams for Indians. Not any more. Bharat Sanchar Nigam Ltd (BSNL) is all set to install and test a killer application that will offer broadband speeds of at least 500 mbps (250 time the current speed) to homes through fibre optics network in Kolkata. Such speeds will be the basic enabler for these dream technologies.
Currently, BSNL offers a broadband speed of 2 mbps that can be stretched to 16 mbps allowing limited internet-based value added services like gaming and steaming video. Mbps is the speed at which a certain volume of data travels every second. Faster speeds help run more intelligent applications.
BSNL is currently working on two technologies. One that will offer speeds of 100 mbps and the other that will allow at least 500 mbps. The 100 mbps project will allow users to make his/her entire house a local area network on which all gadgets like TV, refrigerator, washing machine, micro-wave, gizzard, water filter or the lock at the main door and the gate will be connected. All these can be controlled remotely through a wireless gadget like the cell phone or any other handheld devices.
“These kind of applications require at least 100mbps speeds, termed FTTP (fibre to the premises). Once this speed is achieved a few additional instruments at the users end will enable wireless gadgets to control almost all electronic and electrical devises from remote locations. We are in advanced stage of rolling out this service. It has already been tested and will initially be offered to clusters of housing or large residential campuses. We will roll it out over the next two years,” BSNL’s chief general manager (Calcutta telephones) S K Chakravarti said.
He was talking to reporters on the sidelines of a seminar on telecom organised by Merchant Chamber of Commerce. The 100mbps technology will be based on a combination of fiber optics and ethernet — a kind of a wire currently used in offices to connect PCs on a LAN. “We will supply fibre optics from our exchanges to the premises of a housing complex. A special installation at the base of building will then carry internet (data) to individual flats through ethernet at 100 mbps,” Mr Chakravarti said.
He added: “The second project involves supplying direct fibre optics to individual houses. This technology is technically termed passive optical network (PON) and allows speeds of 500 mbps. A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32. PON does not require those installations necessary for FTTP.” “We have decided to install and test this technology. The project will be initiated next month and will be rolled out as demand for faster broadband rises,” he said.
The broadband technology that offers 2mpbs requires fibre optics to the exchanges. Rest is through copper wire. FTTP is through supply of fibre optics to premises and PON is supply of fibre optics to individual homes. All these will be offered in stages. Interestingly, price of fibre optics have declined by as much as 20% every year over the last three years making these technologies affordable.
“Possibilities are immense. PON will allow video conferencing from home. Professors and teachers will be able to hold virtual classes while doctors will be able to examine their patients from home through a very high resolution image transfer process. It will open a new world of possibilities,” the CGM explained.
