India has been investing heavily in the digital infrastructure space over the past few years, mainly because data usage has grown significantly. 5G roll-out, cloud adoption and the rise of data centres have all added pressure on networks to be faster and more reliable. But building this infrastructure is not just about laying cables across the country. It also involves smaller, less-talked-about pieces like street furniture and in-building networks.
The foundation layer
Optical fibre cable is the backbone of any digital network. It carries data at very high speeds over long distances with very little loss, which is why almost every telecom operator and internet company depends on it. Compared to older copper cables, fibre can handle much larger volumes of traffic and is far more reliable, especially as data consumption keeps rising.
India’s fibre network has been expanding quickly, and reports suggest the growth rate in the country is well above the global average. A lot of this expansion is happening in cities with a strong industrial and IT presence, since these areas generate the most demand. Mumbai, Pune, Bengaluru and Chennai are usually mentioned as leading hubs, partly because of dense population and partly because of the concentration of data centres and enterprises there.
Government programmes have also helped extend fibre networks to smaller towns and rural areas. Meanwhile, operators are increasing fibre connectivity to telecom towers. Fibre provides higher capacity and lower latency than wireless backhaul, making it better suited to handle the growing traffic on 4G and 5G networks.
Still, laying fibre across a city or a state is only part of the job. The fibre needs to actually reach people’s homes, offices and devices.
Street furniture
One of the biggest challenges in expanding fibre and small cell networks in cities is cost and time. Digging up roads, obtaining permissions and managing right-of-way issues can delay projects for months. This is where street furniture is becoming useful. Instead of creating new infrastructure from scratch, operators are using existing structures like lamp posts, traffic signal poles, bus shelters and signage boards to mount fibre access points and small 5G cells.
This approach makes sense on paper. The structures are already standing, connected to power in most cases, and spread across the city in a fairly even pattern. Using them cuts down on trenching costs, avoids repeated road digging and speeds up deployment considerably. As cities look to support more internet of things devices and denser 5G coverage, this kind of shared infrastructure is likely to become more common, not less. It is not a glamorous part of digital infrastructure, but it solves a very practical problem.
In-building solutions
Most of the data we use is actually consumed indoors, not on the street. Homes, offices, malls, hospitals and other buildings account for a huge share of overall internet usage. So even if the fibre backbone outside is strong, the experience can still be poor if the building itself does not have proper connectivity infrastructure.
This is why in-building solutions matter so much. These include things like fibre-to-the-home set-ups, distributed antenna systems and neutral host networks that allow multiple operators to share the same infrastructure inside a building instead of each one installing separate equipment. Newer buildings, especially in metro cities, are increasingly being designed with fibre ducts and structured cabling built in from the start, rather than added later as an afterthought.
Some cities have also started pushing policies that require new constructions to be connectivity-ready before they are approved. This kind of forward planning saves a lot of trouble later, since retrofitting an old building for fibre is usually far more expensive and disruptive than including it during construction.
In sum
Digital infrastructure is often measured by the amount of fibre laid or the number of telecom towers deployed. But these numbers do not always show how well the network serves users. A city may have fibre running across large parts of its road network, while people inside buildings still face poor connectivity because the final link to the user has not been planned properly. This is not really a technology problem at this point, since the technology is already there. It is more of a coordination problem, with telecom companies, municipal bodies and real estate developers still largely working on their own.
A bigger change is needed in how connectivity is planned. Fibre and telecom infrastructure need to be considered while a building or street is being developed, rather than added later when coverage problems appear. This is especially important in large residential and commercial buildings, where indoor connectivity can be difficult to improve after construction. Better planning of fibre, street infrastructure and in-building networks can make it easier to take connectivity all the way to the user.
