5G Internet and Mean of 5G

Superfast "fifth generation 5G" mobile internet could be launched as early as next year in some countries, promising download speeds 10 to 20 times faster than we have now.

So let's learn and understand about the 5G Internet.

What is 5G?

It's the next - fifth-generation of mobile internet connectivity promising much faster data download and upload speeds, wider coverage and more stable connections.

5G performance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. The first phase of 5G specifications in Release-15 will be completed by April 2019 to accommodate the early commercial deployment. The second phase in Release-16 is due to be completed by April 2020 for submission to the International Telecommunication Union (ITU) as a candidate of IMT-2020 technology.

It's all about making better use of the radio spectrum and enabling far more devices to access the mobile internet at the same time.

What it will do for Us?

 Currently whatever we are doing to the current 4G network after launching the 5G network all these things can be faster and better.

Think of smart glasses featuring augmented reality, mobile virtual reality, much higher quality video, the internet of things making cities smarter. and all these things can be operates and mange by 5G network very efficiently and fast.

 

How Does it works? 

There are a number of new technologies likely to be applied - but standards haven't been hammered out yet for all 5G protocols. Higher-frequency bands - 3.5GHz (gigahertz) to 26GHz and beyond - have a lot of capacity but their shorter wavelengths mean their range is lower - they're more easily blocked by physical objects.

So we may see clusters of smaller phone masts closer to the ground transmitting so-called "millimetre waves" between much higher numbers of transmitters and receivers. This will enable higher density of usage. But it's expensive and telecoms companies are not wholly committed yet.

How it is different from 4G

5G will offer much higher bandwidth and capacity than 4G services. 5G not only unlocks more wireless frequencies to use between 5G NR (new radio) and mmWave (millimeter wave), it’s also designed to makes better use of what’s available between potentially many thousands of users in urban environments.

5G can offer a much lower latency than 4G. Ultra-low latency is desirable to consumers who expect a real-time response (video calling, streaming, etc), however 5G can even support some scenarios where an immediate response is not just preferred but mission critical: such as medical applications.

5G is a brand new technology, but you might not notice vastly higher speeds at first because 5G is likely to be used by network operators initially as a way to boost capacity on existing 4G (LTE - Long-Term Evolution) networks, to ensure a more consistent service for customers. The speed you get will depend on which spectrum band the operator runs the 5G technology on and how much your carrier has invested in new masts and transmitters.

Why we need 5G?

The world is going mobile and we're consuming more data every year, particularly as the popularity of video and music streaming increases. Existing spectrum bands are becoming congested, leading to breakdowns in service, particularly when lots of people in the same area are trying to access online mobile services at the same time. 5G is much better at handling thousands of devices simultaneously, from mobiles to equipment sensors, video cameras to smart street lights. 

Will it work in rural Areas?

Lack of signal and low data speeds in rural areas is a common complaint in the India and many other countries. But 5G won't necessarily address this issue as it will operate on high-frequency bands - to start with at least - that have a lot of capacity but cover shorter distances. 5G will primarily be an urban service for densely populated areas. 

How to Hide Whats Profile Picture from Specific Contact

Facebook-Owned instant messaging platform WhatsApp is one of the most used instant messaging app.It's used by million of users around all over the world.In the last couple of months, we have seen several new feature added to the app such as two step verification, hiding status, hiding profile picture and more.

But there's one things that's missing that WhatsApp does not have direct option that gives the user customize profile picture privacy setting for specific contacts.Having said that sometimes we just want to hide our profile picture or status from only one contact or a number of people without completely blocking them.

Let's know how to hide profile picture from specific contact.

Google Assistant (Google Home)

Google is one of the most popular technology company headquarter in Mountain View, California United State of America.Its provide internet services and product which include online advertising technologies, search engine, cloud computing, software and hardware.

Google Home

Google home is a smart speaker developed by Google. The first device is announced in May 2016 and release in the United States in November 2016, with subsequent release globally throughout 2017 and 2018.

It's great at answering questions, setting timers and playing music, but it's also really useful for  controlling your smart home devices, such as locks, light and more.

 

Google Home speakers enable users to speak voice commands to interact with services through Google's personal assistant software called Google Assistant. A large number of services, both in-house and third-party, are integrated, allowing users to listen to music, control playback of videos or photos, or receive news updates entirely by voice. Google Home devices also have integrated support for home automation, letting users control smart home appliances with their voice. Multiple Google Home devices can be placed in different rooms in a home for synchronized playback of music. An update in April 2017 brought multi-user support, allowing the device to distinguish between up to six people by voice. In May 2017, Google announced multiple updates to Google Home's functionality, including: free hands-free phone calling in the United States and Canada; proactive updates ahead of scheduled events; visual responses on mobile devices or Chromecast-enabled televisions; Bluetooth audio streaming; and the ability to add reminders and calendar appointments.

Manage Your Day

Get personalized help with your schedule, reminders, news and much more, whenever Google Home recognizes your voice.

                  "Hey Google, what is traffic like on my way to work? " 

    "Hey Google, When's my first event tomorrow?"

Entertainment Hands-Free

Google Home works with Chromecast, so you can stream shows, movies and music on your TV or speakers.

How to send Message Securily

We have seen that in many cases when we are sending message, we want that no one can see our message only receiver able to see those message for sending the message we can use cryptography and steganography is one of the technique of cryptography..
 So today we will learn about steganography and how the message will be send using this technique.

Steganography

Steganography is a technique of hiding data within data. Encryption can also be used in steganography to protect data to access the unauthorized user.
      Steganography can apply with images,audio,video files.Typically, however, steganography is written in characters including hash marking, but its usage within images is also common. At any rate, steganography protects from pirating copyrighted materials as well as aiding in unauthorized viewing.

Let's see how steganography will be apply with image.

Step1:- Open command prompt in your PC/Laptop.

Step2:- type

   echo  message >> image file name

ex.   echo " hello juliya how are you?" >> xyz.jpg

Now your message have written in the image and image is look like a simple image you can see your written message thru right click of image and then go edit with any text editor then in the last you will see that your message is write.
