The Reality of 4G in India

Despite having a 4G network, Indians are still suffering from buffering. The average 4G LTE data speed in India stands at 6.1Mbps, while the global average is 17 Mbps. According to mobile analytics company open signal, 4G download speed in India is slowest across 88 countries spanning six continents. Even if subscribers in countries like Pakistan & Algeria enjoy internet at a speed of 14 Mbps & at 9 Mbps.
According to online speed Tester Ookla India ranked 109th–almost at the bottom in its list of 124 nations.


Ookla spokesman Adriane Blum said another possible reason behind India’s slower mobile internet speeds is the challenge of serving an extremely dense population. Experts also said a country’s 4G speeds also hinge on how much spectrum is devoted to LTE, whether it has adopted new 4G technologies like LTE Advanced, how densely networks are built and congestion levels. “The spectrum per operator in India is low compared to other countries, which affects 4G network speeds,” said Rajan Mathews, director general of the Cellular Operators Association of India.
Some analysts partly ascribed the phenomenon to higher latency levels of Indian telecom companies. Latency is a measure of the delay that users experience when their computers/smartphones try to access internet servers. Lower latency connections typically mean webpages load faster and videos start playing sooner.
Daily concerns like Server down at ATM, getting stuck while making online payments waiting for uploading of the web page.
While most companies are aggressively pitching about 5G, Indian subscribers are still in dilemma that will they get the speed according to global standard or their hard earned money will be looted in the name of 5G. Concerns over poor services & slower speed are a vogue now. It is a big issue as the Indian government is offering many online services. I often listen that people are saying that Think out of the box. I think that first, we should be aware of the dimension of the box. So, let the 4G network can spread successfully throughout India so that we can proudly say that we are in digital India.

Bluetooth

Bluetooth is wireless technology used everywhere. There come many versions in every year which fulfills the demands of users of that year. But with the advancement in everything, users also want some new and tempting feature for Bluetooth. The new versions have changes and more support than the previous ones. Now the Bluetooth 5 has released which promises to deliver best and quality connectivity to its users. Bluetooth 5 has come with dramatically improved performance and functionality.

The Bluetooth SIG presented Bluetooth 5 on 16 June 2016. Its new features are mainly focused on emerging Internet of Things technology. The Samsung Galaxy S8 launched with Bluetooth 5 support in April 2017.

Connecting Where We Work, Live, & Play

Bluetooth® technology is connecting cities to enhance the visitor experience and improve the quality of life for citizens, businesses, and employees around the globe. Bluetooth beacons create rich, personalized experiences for concert goers, museum lovers, sports fans, and tourists. Bluetooth also powers a growing bike-sharing industry that is changing how residents make their way around urban neighborhoods and bringing the sharing economy to life.

As pressure on resources, utilities, and public funds increases, so too does the need for smarter solutions to effectively manage growing city populations. Bluetooth helps public officials connect city infrastructures in ways never before imagined and gather data to guide informed policy making.

Key Uses-

Bluetooth_5Smart Buildings
The smarter the buildings, the smarter the city. Bluetooth enables the automatic, centralized control of a building’s essential systems, including heating, ventilation and air conditioning (HVAC), lighting, and security. Building automation harnesses energy savings, lowers operating costs, and improves the life cycle of a building’s core systems. Bluetooth technology also powers building-wide networks of sensors and beacons that enable indoor positioning and location services like way finding, asset management, and point-of-interest solutions.

These intelligent Bluetooth devices are driving advancements in smart tourism. They help venues like museums, stadiums, and airports guide visitors to where they need to be and provide them with a more personalized and fulfilling experience. Smart cities also leverage Bluetooth technology to boost local retail. Beacons power proximity marketing services and apps that help stores attract shoppers in the vicinity.

Bluetooth_7Smart City Management
Government officials and city managers turn to Bluetooth to increase energy and operational efficiency and maximize resources and budget. Bluetooth roadside traffic sensors help officials map public transportation routes and allocate resources more efficiently based on demand and traffic patterns. Bluetooth beacons enable smart parking systems, create efficiencies in public transportation, and give city officials the data they need to make confident policy decisions.

Bluetooth_9Beacon
A beacon is a small Bluetooth radio transmitter.
It’s kind of like a lighthouse: it repeatedly transmits a single signal that other devices can see. Instead of emitting visible light, though, it broadcasts a radio signal that is made up of a combination of letters and numbers transmitted on a regular interval of approximately 1/10th of a second. A Bluetooth-equipped device like a smartphone can “see” a beacon once it’s in range, much like sailors looking for a lighthouse to know where they are.
