What Is 5G, Exactly? 5G is a term used to describe the forthcoming fifth generation of mobile network technology. Right now, it doesn't signify any particular type of technology. While 4G has become synonymous with LTE, there's been no publicly agreed upon standard for 5G networks. However, a couple of likely technologies are emerging. 5G networks will use a type of encoding called OFDM ( Orthogonal Frequency Division Multiplexing ) , which is similar to the encoding that LTE uses. The air interface will be designed for much lower latency and greater flexibility than LTE, though. The Next Generation Mobile Networks Alliance defines the following requirements for 5G networks: Data rates of tens of megabits per second for tens of thousands of users 1 Gb per second simultaneously to many workers on the same office floor Several hundreds of thousands of simultaneous connections for massive wireless sensor  network Spectral efficiency signifi...

What is HaLow? There's a new wireless networking protocol in town and it comes to bring connectivity to the Internet of Things. Wi-Fi HaLow (pronounced "HAY-low") is a marketing name used for products that utilize the IEEE   802.11ah   wireless technology, which offers longer range and lower power connectivity than traditional WiFi -certified products. Wi-Fi HaLow is the latest specification from the Wi-Fi Alliance looking to expand the range of Wi-Fi's connectivity options.  Wi-Fi HaLow will be able to easily work through walls and large barriers because of the propagation capabilities of low-frequency radio waves, as it will operate in the unlicensed wireless spectrum below 1GHz. HaLow’s range will be nearly double the range of today's Wi-Fi, with estimates extending as high as a whopping 3,280 feet.   HaLow is designed for the Internet of Things , designed to connect multiple devices wirelessly, over extended distances and using lower power...

What is Li-Fi? Light Fidelity or  Li-Fi   is a Visible Light Communications (VLC) system running wireless communications travelling at very high speeds. Li-Fi uses common household LED (light emitting diodes) lightbulbs to enable data transfer, boasting speeds of up to 224 gigabits per second . The term Li-Fi was coined by University of Edinburgh Professor Harald Haas during a TED Talk in 2011. Haas envisioned light bulbs that could act as wireless routers. How it works? Li-Fi and Wi-Fi are quite similar as both transmit data electromagnetically. However, Wi-Fi uses radio waves while Li-Fi runs on visible light . As we now know, Li-Fi is a Visible Light Communications (VLC) system. This means that it accommodates a photo-detector to receive light signals and a signal processing element to convert the data into 'stream-able' content. Visible Spectrum An LED lightbulb is a semi-conductor light source meaning that the constant current of...

Happy 70th Independence Day - 2016 Independence Day is an annual observance celebrated every year on 15 th of August. India’s Independence Day is a day of great significance for the people of India. At this day India got freedom from the British rule after long years of slavery. It has been declared as the National and Gazetted Holiday all across the India in order to independently commemorate the independence of country from British Empire on 15 th of August in 1947. The first Independence Day was celebrated in India on 15th of August in 1947. What’s Special on 70 th India’s Independence Day 2016 As per the media report, there is a plan by the Indian prime minister, Narendra Modi, to launch a programme named as “70 Saal Azadi-Zara Yaad Karo Kurbani”, also called “AZADI70” (means, 70 years of independence-Do recall the sacrifices). The aim of this campaign is to make Indian people aware that country is first and individual is secondary as well as remember t...

What is Project Loon? More than half of the world's population is still without Internet access. Project Loon is a network of balloons traveling on the edge of space, designed to extend Internet connectivity to people in rural and remote areas worldwide History  In 2008, Google considered contracting with or acquiring Space Data Corp., a company that sends balloons carrying small base stations about 20 miles (32 km) up in the air for providing connectivity to truckers and oil companies in the southern United States, but didn't do so Unofficial development on the project began in 2011 under incubation in  Google X  with a series of trial runs in  California 's  Central Valley . The project was officially announced as a Google project on 14 June 2013 The project has run its experimental pilot in New Zealand, Calafornia’s Central Valley, northeast Brazil, South Africa, Sri Lanka (in February),  as well as in I...
