Jio True 5G: Trial Review at Barrackpore
Though India's first spectrum auction for 5G airwaves was conducted in July this year, the telecom service providers - Jio and Airtel did make a hurry to launch 5G, unlike 3G or 4G. 5th generation of telecom services went mainstream in India on October 1st, 2022. That's just 2 months to get 5G live. Well that's fast, and thanks to DoT, all operators got trial spectrum to conduct 5G trials and tests on their 2G/3G/4G networks. Debt ridden telco Vi is yet to announce its 5G debut.

ব্যারাকপুরের গপ্পোঃ ডাক্তার ভোলানাথ বসু
ব্যারাকপুরের সরকারি হাসপাতালটির নাম ডঃ বি.এন. বসু মহকুমা হাসপাতাল (Dr. B.N. Bose Sub-Divisional Hospital)। অনেকেই একে বীরেন বোস হাসপাতাল বলে ভুল করেন। কিন্তু কে ছিলেন এই ডাঃ বি.এন.বসু?
B.N.Bose এর পুরো নাম ভোলানাথ বসু। ১৮২৪ সালে (মতান্তরে ১৮২৫ সালে) ভোলানাথ বসু চানক মৌজার তালপুকুর গ্রামে জন্মেছিলেন। এই চাণক-ই পরবর্তী সময়ে ব্যারাকপুর নামে পরিচিত হয়ে ওঠে। তাঁর বাবার নাম ছিল রামজয় বসু। তাঁদের বাগানবাড়ির বিস্তীর্ণ জমি ৫০ বছর আগেও বোসবাগান নামে পরিচিত ছিল। পরে কৃষ্ণনাথ মুখোপাধ্যায় তা কিনে নিয়েছিলেন। এই জমিতেই আজ জিমন্যাশিয়ামের বিশাল মাঠ।
প্রথমে তিনি গ্রামের পাঠশালায় পড়াশুনা করলেও পরে তিনি লর্ড অকল্যাণ্ড প্রতিষ্ঠিত ব্যারাকপুর বিদ্যালয়ে (আজকের ব্যারাকপুর গর্ভমেণ্ট স্কুল) ভর্তি হয়েছিলেন। লর্ড অকল্যাণ্ড এবং তাঁর বোন এমিলি ইডেন মূলত চারপাশের লোকালয়ের বাঙ্গালী ছেলেদের জন্যই এই স্কুলটি স্থাপন করেন। তারা মাঝে মাঝে সেই বিদ্যালয়টি পরিদর্শন করতেন এবং পড়াশুনার ব্যাপারে ছাত্রদের উৎসাহ দিতেন। ১৮৪০ সালে লর্ড অকল্যাণ্ডই ভোলানাথকে কলকাতা মেডিক্যাল কলেজে ভর্তি করিয়ে দিয়েছিলেন। শুধু তাই নয়, তিনি ভোলানাথ বসুর জন্য মাসিক দশ টাকা বৃত্তির ব্যবস্থাও করে দিয়েছিলেন।

Kolkata's Cheenepara: Toong On Church
Introduction to Kolkata's old China Town - Tiretti Bazar can be found here.
It can be assumed that the immigrant Chinese had no exact word for their place of worship and community meeting place - they started calling them as church as the British called their own place of worship. Though these Taoist temples have no link of Christianity.
Just like Kolkata's old China Town is more than the Chinese Breakfast, these Taoist temples are more than religious centers.
Toong On Church is the first Chinese temple you will find if you are coming from the Central Metro station.

Old China Town in Kolkata - Introducing The Bazar of Mr. Tiretta
Though I have written about Old China Town previously on my blog, this one is distinct cover up on the Old China Town of Kolkata.
Introduction: Old Chinatown of Kolkata - Teriti Bazar
Chinese people has long history of coming to India since the time of Fa Hien in early 400's and Hiuen Tsang during 600's. But in modern India Yang Daijang (British called him Tong Achew /টং অছি) was the first Chinese man to settle in Budge Budge, 33 km south of Calcutta. The place Achipur (আছিপুর), near Budge Budge is named after him (Achew). He started a sugar mill there in 650 bighas of land when Warren Hastings was the Governor General (1774-1785). Many says the sugar got its Bengali name, Cheeni (চিনি) as it was made by the Chinese immigrants.

Private 5G networks are the latest excitement to the industry, as it would support Indian enterprises preparing for the Industry 4.0 revolution.

Which Processors Support NavIC, India's Answer to GPS?
If you don't know about NavIC, it is actually India's home grown satellite navigation system. Yes, it's like GPS. GPS is American made, and NavIC is made by Indian Space Research Organization (ISRO). NavIC is the short form of Navigation with Indian Constellation. It is also known as Indian Regional Navigation Satellite System (IRNSS).
As NavIC is available for civilian use over L5 band (and S band for military use), it is now offering regional coverage covering India and a region extending 1,500km around it. While American GPS, Russian GLONASS, European Union's Galileo, China's BeiDou have global coverage, i.e. all these 4 satnav services are Global Navigation Satellite System (GNSS). NavIC presently using only 7 satellites to cover a region centering India. As 4 out of 7 satellites are geosynchronous and remaining 3 are geostationary - as a result the satellites are always in line with Indian territories - that makes geolocation highly precise.
History of NavIC began in 1999, when US denied specific GPS data to India during Kargil war. The project of Indian GPS or IRNSS was approved in 2006, and planned to go operational by 2011. But it got delayed, eventually NavIC was launched in 2018.

Barrackpore Christian Cemetery - Commonwealth War Graves
ব্যারাকপুরে বেশ কিছু ঐতিহাসিক 'Hidden Gem' আছে। তার মধ্যে বেশিরভাগই আর্মি বা পুলিশের জায়গাতে অবস্থিত বলে সাধারণের নাগালের বাইরে। আজকে যেটা নিয়ে কথা বলব সেটা কিন্তু সবার নাগালের মধ্যেই - কিন্তু Cantonment এরিয়ার ঠিক বাইরে আর রাস্তা থেকে একটু ভিতরে থেকে বলে বেশিরভাগ মানুষই এর ব্যাপারে জানেন না। ছোটবেলায় এই সব এরিয়াতে সাইকেল চালিয়ে অনেক ঘুরেছি, আমিও জানতাম না এর ব্যাপারে। এটি হল ব্যারাকপুরের খ্রিস্টান কবরস্থান বা Commonwealth War Graves। ২০১৯ সালে West Bengal Heritage Commission এই জায়গাটিকে 'হেরিটেজ সাইট' হিসেবে নথিভুক্ত করেন - গেটে লাগানো হয় ব্লু প্লেক (Blue Plaque)।

Adani's Plan for Private 5G Focuses on Certain States Only
Just before the start of 5G auction of India, Gautam Adani owned Adani Group had cleared the fact that they will not enter into commercial mobile space and they did the exact in the Spectrum Auction 2022. Adani Data Networks Ltd (ADNL), an arm of Adani Enterprises picked up spectrum in the mmWave band i.e. 26 GHz band only, and that too only in key 6 circles - Andra Pradesh, Gujarat, Karnataka, Mumbai, Rajasthan and Tamil Nadu where industrialization is in massive scale and the scope of private 5G would be huge. They even did not spend money to win spectrum in Delhi-NCR circle. That's definitely not an aggressive bidding from Adani Data Networks.

Top Biriyani Houses in Kolkata
Without any introduction it is obvious that Biriyani is the most popular dish in India, though it has several local varieties. Online food order & delivery company Swiggy notes that Indians ordered whopping 115 biriyanis per minute in 2021. They also noted that 4.25 lakh new Swiggy users chose it as their first order. On a funny note, Swiggy also remembers that their delivery partner travelled longest 39.3 Km to deliver biriyani in 2021.
Biriyani came from the Persian word, 'Beryan' which means 'fried before cooking'.

Alliance vs Jio Fiber : Tariff Comparison
West Bengal’s top broadband provider, Alliance Broadband has expanded their coverage outside Bengal. It is now available in Bangaluru, Chennai, Mumbai and Hyderabad.
For the uninitiated, Alliance Broadband has became the top broadband player in West Bengal for last 7-10 years, beating the state-owned BSNL. Technically Alliance was offering cable broadband while BSNL relied on ADSL technology initially, but both now have moved to Fiber in most of the areas. Fiber offers faster data than cable or ADSL, and maintenance charge is also low. For last some years the cost of rolling out fiber has been declining due to huge deployment across the globe.
At present I have both Jio Fiber and Alliance Fiber connection at my home. Downtime is rare with Jio, while Alliance has some 30hr+ downtime in my area, thanks to local operator. Also during thunderstorm Jio never goes off - making it seamless internet experience.

Jio Updates: Jio Enters into Satellite Internet Biz
This update which came in February, 2022 is actually a big update, though Jio did it silently - Jio enters into satnet biz by founding Jio Space Technology Limited (JSTL) by creating a JV with Luxembourg based SES (Société Européenne des Satellites).
Jio owns 51% of the JV, while SES holds the remaining 49%. SES is already an established player in satcom business and newly formed entity will use multi-orbit space networks that is a combination of geostationary (GEO) and medium earth orbit (MEO) satellite constellations capable of delivering multi-gigabit links (upto 100Gbps) and capacity to enterprises, mobile backhaul and retail customers across the length and breadth of India and neighbouring regions.

EV Boom in India, Nexon EV vs Nexon EV Max
India is getting its EV boom in the 4-wheeler car market. Lead by Tata Motor’s flagship Nexon EV the car market is bound to change in coming years. Though luxury car makers like Audi, Jaguar, Porsche have their EV models, but these cars never are aimed for mainstream. And it would be shameful not to mention Tesla, which may have 1/3rd of EV car market in America and Europe, is yet to be present in India.
Tata Motors
has launched their upgraded Nexon EV as Nexon EV Max, and will roll out Tiago
EV soon. They already have another EV - Tigor EV. That would make Tata Motors
with maximum EV offerings in India - 4 EV cars. At a point Tata Motors can be India's answer to Tesla.
Other EV
cars in India are - MG ZS EV (from Rs 20.88 L), Hyundai Kona Electric (from Rs.23.71
lakh), Mahindra e-Verito, Mahindra e2oPlus.
And those
are already in the list to be launched are, Mahindra e-KUV100, Nissan Leaf,
Mahindra XUV300 EV, and Tata Tiago EV.
Interestingly top automaker in India, Maruti Suzuki is yet to be join the EV race. As per reports, Maruti Suzuki is working with Toyota for a mid-sized EV SUV, codenamed YY8.

Jio Updates: Jio's Tower Arm Got New Branding under New Ownership
It is a late update #1 on Reliance Jio.
Back in December 2019, Jio announced Canada-based Brookfield Infrastructure Partners LP and its institutional partners (including Singapore's sovereign wealth fund GIC) would bought Jio's telecom assets through some complex deal. The valuation was Rs 25,215 cr. In September 2020 DoT cleared the transaction.

Website of Summit Digitel: https://www.summitdigitel.com/
Facebook page of Summit Digitel: https://www.facebook.com/SummitDigitel/
In March 2022, BSNL has inked a pact to use Summit's passive infrastructure assests, while in April Airtel did similar agreement with it.
In December 2020, Summit Digitel joins Tower and Infrastructure Providers Association (TAIPA).
TAIPA has members like: Indus Towers Limited, ATC Group Companies, Tower Vision, Ascend Telecom Infrastructure, Sterlite Technologies, Space World, Coslight, Suyog Telematics, Applied Solar Technologies, iBus Networks and Summit Digitel Infrastructure.
TAIPA did a makeover in September 2021, as Digital Infrastructure Providers Association (DIPA) (https://dipa.co.in/). The rebranding came in the time to reposition itself as the representative body for digital communication industry players while aligning with future industry requirements.

Windows 11 Experience - Issues and How to Solve it
This year (2022) I bought a new laptop - HP 14S - running on AMD Ryzen 5 5500U with Radeon Graphics 2.1GHz, which comes with Windows 11 Home version.
This article is made to list the issues faced with Windows 11. Back in 2005, I was on Windows XP on my first desktop, when many computer users were still stuck to Windows 98.

But had to move on to a new laptop, as I have transition to Windows 11 in 2022.

Mavenir Backing Open RAN Aggresively & Curious Case of India's 5G
Way back in September 2020, I wrote up on Open RAN networks and how it is reshaping future of telecommunications globally. After 1.5 years that O-RAN is very much alive and getting more traction from the industry. ORAN is now widely accepted globally. For those are uninitiated, Open RAN (Radio Access Network) offers the flexibility to the service providers to use hardware and software solutions from different companies in multiple layers. It's something like to use open source software.

FDA Approves Two Oral Antivirals against COVID-19 - India Got One of Them
COVID-19 Pandemic which started in 2019 is probably getting into its last phases as third wave hits India in December 2020-January 2021. Thankfully now we have got two oral drugs against SARS-CoV2 virus which is responible for COVID-19 diseases. So far as per our experience the latest variant of SARS-CoV2, aka Omnicron is the causative agent in the third wave.
America's drug controller FDA (Food and Drug Administration) has approved these two anti-COVID oral antivirals as Emergency Use Authorization (EUA) - Molnupiravir and Paxlovid.

Buy Now Pay Later (BNPY) Offerings in India
Though 'buy now, pay later' schemes are available in the market in the form of credit cards in India for many years, new concept of BN-PY was around for 5-7 years. First I heard of LazyPay and Simpl from my brother who was using them in Chennai for heavily discounted foods and etc. Then I got to know about Ola Postpaid which offers cashless rides and generate a monthly or 15-day bill to pay the ride charges at one go. The best part of this BN-PY schemes are while you pay later there is no interest charge (similar to credit cards with 30 day bill) but often these are easy to grab (not subject to approval from banks for a credit cards) - so for students or youngsters LazyPay, Simpl, Ola Postpaid were a hit.
