Vi 5G Review: Speedtest Results in Kolkata

Vi, the third largest mobile operator of India, has launched 5G, and it is now in Kolkata too, but in a few pockets of the metro. Though it's not present at my home area, it is widely available in Salt Lake. 

To deploy 5G, Vi took a multi-vendor strategy - made deals with Samsung, Nokia and Ericsson for different circles. In Kolkata Nokia is the vendor of Vi 5G. 

BSNL 4G Officially Launched on 27th September 2025 - Discussions

BSNL, the state owned telecom service provider has officially launched its 4G-LTE services in India in an event at Jadsuguda, Orissa as India's prime minister Narendra Modi unveiled Swadeshi 4G network of BSNL on September 27, 2025. In fact, BSNL completed its 25 years of milestone of September 26, 2025. 

BSNL has deployed indigenous 4G stack, made by Tata backed Tejas Networks & TCS and C-DoT. Multiple Indian startups are also part of it. It is aligned with the government's strategy of Atmanirvar Bharat (Self reliant India). 

Jio Deploys 5G-NR Country-wide, Details of UBR based Jio AirFiber

From the very beginning of deployment of cellular technology, India had behaved like any 3rd world country - late deployment, poor services and poor adaption. However since 2015 the perception gradually has been changed, all thanks to Mukesh Ambani backed Reliance Industries' telecom arm - Jio. 

Now Jio has launched 5G-SA and brought 5G-FWA (fixed wireless access) to connect homes with wireless broadband. Initially Airtel with their 5G-NSA could not enter into 5G-FWA market as 5G core is very much essential for roll out 5G-FWA, but they now entered into 5G-FWA market with their limited 5G-SA deployment. 

Coffees in India - Listing of new brands.

Over a cup of coffee

Coffee is an interesting drink, common to most Indian household, be it north India or south India. Coffee is not a native to India, rather in 17th century Sufi saint Baba Budan brought coffee seeds from Yemen, and started coffee plantation in Chikmagalur, a hill station on the Western Ghats, in Karnataka. Hence most of the coffee production are done in southern states like Karnataka, Kerala, Andhra and Maharashtra. Other states are Assam, Meghalaya, Nagaland, Tripura are also producing some amount of coffee.

Nescafé, owned by multinational company Nestlé is probably the most popular coffee brand in India. Next is Bru, now owned by Hindustan Unilever Ltd (HUL) - which was launched in India in 1968. Tata Coffee, with history of more than 90 years is another popular name among Indian coffee lovers. Others names include Davidoff - the luxury coffee brand, Cafe based Starbucks India and Coffee Day. The later mentioned coffee cafes like Starbucks, Café Coffee Day, Costa Coffee (now owned by Coca Cola) and Barista (https://www.barista.co.in) are also creating the traction of coffee popularity across the country. 

Private 5G: BSNL Cracked Two Deals

Indian operators are banking on FWA to make 5G tech monetized, but the most effort on FWA is being played by Jio. The next monetizing factor could be deployment of private 5G networks. First trial of private 5G network was done by Airtel, back in July 2022, at Bosch Automotive Electronics India Pvt Ltd's facility in Bengaluru using trial 5G spectrum allocated by the Department of Telecom (DoT). 

But private 5G network is not getting much demand from the enterprises, as many want to deploy bypassing the present telecom operators - as the companies want their own spectrum and will bring their own technology partner to deploy private 5G. Even if the business sector starts working with the telcos, the spectrum will be another issue. 

Road to 6G: 5G to 5G Advanced and 6G

When Chromebook was first launched in India in 2013, we were yet to get 4G. That time 3G from Indian operators was patchy, slow and too much costly! Airtel just launched 4G in 2012, which was not welcomed by the users. I could not take that cloud computing in India could be a future with such slow speed. 

Cut to post-COVID era, many are still working from home with the help of Cloud computing. India got 4G in 2012 but 4G went mainstream when Jio started offering free 4G data w.e.f. December 2015. Now 5G was launched in India in October 2022 by both Jio and Airtel - and both are offering free unlimited 5G data on the top of selected 4G plans. India's 5G adoption was very fast, and at par with global rollouts. 

BSNL to Launch 4G with Indigenous Gears, Jio too Switching to Desi

Despite multiple delays to launch 4G services, Bharat Sanchar Nigam Ltd (BSNL) - the state owned telecommunications service provider is seemed to be on the track to roll out the much awaited 4G-LTE services across the circles very soon.

As per the deal signed in August 2023, Tejas Networks-led consortium would be delivering 4G sites to BSNL worth Rs 7492 crore. Initially there was extensive trials run across the circles. On May 5, 2025 Tata backed telecom gear firm Tejas Networks announced that the company shipped more than 100,000 sites for BSNL's 4G/5G-ready network. This is one of the largest single-vendor RAN networks in the world ever delivered in record time.
