Google's New Project- Soli

"Your hands are the only interface you'll need"- Google

Soli is the new touchless radar-based sensing technology by Google. It is a small chip which may integrate in the future phones to make it touchless.

There was a time when you use buttons to use your phones. Then an era of touchscreen came. Now the future era may be based on Google's Soli where you can give the command to your phone just by creating a sensation in the air and this radar-based sensor will detect your motion.

Soli tracks and recognizes dynamic gestures expressed by fine motions of the fingers and hand. This tool is based on the virtual tool gesture. You can press it by tapping your fingers together. Rub your thumb against your index finger to turn on the virtual dial. Slide your thumb over your index finger to slide the stuff. This kind of interactions is being developed by GoogleThis chip is smaller than a 1 Rupee coin. Indeed it is ultra-compact 8mm x 10mm. Sensor and antenna are incorporated within it. 
Soli sensor technology works on electromagnetic waves in a broad beam. Objects within the beam scatter this energy, reflecting some portion back towards the radar antenna. The reflected signal, such as energy, frequency, and time delay capture rich information about the object's characteristics and dynamics, shape, size, and orientation. Soli chip can be integrated into IoT devices, computers, cars, smartwatches and of course in smartphones.

We may see the integration of Soli Sensor in Google's upcoming flagship smartphone- Google Pixel 4 XL

"I have just explained the upcoming sensor by Google i.e. Soli- a radar-based sensor in very simple language. Hope you guys understand it clearly."

How WhatsApp make money

We all know that WhatsApp is one of the biggest freeware social networking platforms. Currently, Whatsapp has 1 billion monthly active users. Do you know how WhatsApp make money?

Let's read this article:

WhatsApp was founded in 2009 by Brian Acton and Jan Koum as an alternative to pricey SMS services. The app allows users to upload their contact book and message anyone who has the app installed at no cost.

Facebook Inc. purchased WhatsApp in February 2014 for $19 billion, and according to the 2014 Facebook Form 10-Q, in the nine months preceding September 30, 2014, WhatsApp generated revenue of $1,289,000. How is WhatsApp making its money?
WhatsApp makes money in a different way, they didn't earn directly from WhatsApp service or any ad promotion.

Let me show you:

More than one billion people are now using Whatsapp every day in the world. Currently, 55 billion messages are being sent per day. 4.5 billion photos are being sent per day. Currently, it supports 60 languages all over the world. It is not like a traditional SMS app, it has much more good features. It is increasing and expanding at every moment. Still, now it is totally free of cost.

Now the story is:

You don't know after buying WhatsApp, Facebook has increased their net growth revenue in a multifold. Facebook knows all about you even you don't know about that information of you, sometimes you forget those small incidents. They have made a large database from WhatsApp. They are able to serve interest-based advertisement now.

Let's talk about it:

• Facebook knows about your personal information.
• Facebook knows about your professional information.
• It knows about your relationship and families.
• It knows what you like or dislike.
• It knows what kind of activities you are doing each and every day sometimes you forget about those activities but Facebook remembers it.
• Even they know about your mental and emotional situation. Sometimes you ignore these things but Facebook does not ignore, it records all these small things in their database system.
• It knows what you want and what you don't want in your daily life.
• It knows where you go when you go and why you go they always follow you (internet location services, group activities and status updating).
• Its ad performance is the best in the world, totally 100% target and interest-based ad they are selling.

So, the Facebook team is using their WhatsApp database system to grow and helps to achieve their target. Sequoia Capital invested around $8 million in the company, and many other investors are interested in investing in the venture. In India, Reliance Communications has teamed up with WhatsApp for providing a unique scheme for Reliance's prepaid users -- a WhatsApp Plan. So, WhatsApp is making money by tie-ups with popular telecom companies as well.

I have just explained 'How WhatsApp make money?' Hope you guys understand and find this article interesting.

Qualcomm Snapdragon 855, X50 and 5G compatibility

Snapdragon 845's elder sibling will be based on 7nm

Qualcomm Snapdragon 845 is the flagship chipset based on 10nm but its successor is set to release with the 7nm process.

Qualcomm is working on its next premium mobile chipset that will probably be called as Snapdragon 855. Although, the Qualcomm has not yet confirmed the name of its next flagship chipset but it has confirmed that it will be based on 7nm process while its predecessor, 845, is based on 10nm.
Snapdragon 855

Power Efficient

The 7nm process will allow the chipset to boost 20-30 percent performance and become more energy efficient than Snapdragon 845. Snapdragon 845 offers the GPU Adreno 630 whereas the upcoming 855 SoC will have Adreno 640 which will boost 20 percent performance with 30 percent reduction in power consumption.

5G Compatible

This year everyone talks about the 5G connectivity. So the wait is about to end. As the Snapdragon 855 comes with 5g compatibility. The 7nm SoC will be paired with the Snapdragon X50 modem. This will be the first 5G-capable mobile platform for premium range smartphones.

Artificial Intelligence (AI)

As far as AI matters, both Snapdragon 845 and Snapdragon 855 are Al-powered. This will use Al noise cancellation to block all the unnecessary sound around you. Suppose you get a call in a crowded place, this AI noise cancellation will help you by blocking all the ambient noise so that the recipient can hear your voice easily. The Google Assistant and the Alexa, the two voice assistants, may be embedded in the Snapdragon 855 with voice wake up command.
