Reliance Jio To Launch 4G VoLTE Smartphone At Rs 1000

Hey webber

Ohh my god again surprising news from Reliance Jio, Reliance Jio owner Mukesh Ambani decided to launch 4G VoLTE technology based LYF smartphone. As the Jio team decided the price of this smartphone will be around 1000 RS to 1500 RS.

Getting the knowledge about the smartphone specification some facts are uncleared the basic thing which is announced by the developer team is that the processor going to use is Spreadtrum 9820.
Features like Camera,Bluetooth,Wi-Fi and other will be included like other smartphone has.Screen Display will be of 4.5 inch size.

Basically VoLTE stands for Voice Over Long Term Evolution and it’s more or less exactly what it says on the tin. It’s voice calls over a 4G LTE network, rather than the 2G or 3G connections which are usually used. We tend to think of 4G as mostly being about downloading, streaming and web browsing, and indeed that’s primarily what it’s been used for so far, but it can also be used to improve calls.

Profits when we will use it -
1. Superior call quality
2. Improved coverage and connectivity
3. Better battery life
4.Video calling – It’s also theoretically possible to make video calls over 4G, much like a Skype call   except you’d just use your mobile number and be able to use the regular dialer and call interface, so you can make and receive video calls from anyone else with VoLTE, rather than relying on separate accounts.

Here we can say that all these features will be in Jio's upcoming smartphone.

That was ultimately praise of Reliance Jio but regarding to the services that they are providing question will arise that Are they going to stay on their promise that they made ?

Saying this because Jio speed was 7.2 Mbps in September  and later fall by 20 percent in October they provided 6 Mbps. This speed is  a half of Airtel's 4G as Airtel provides 11.47 Mbps.

But no matter at all, its Reliance group the can manage it very well as they extended the welcome offer to March 2017 for their customers.

Now its time to wait for their smartphone.

Information Security Series - Tunnel Bear VPN

Hi webious readers,

I am going to write a number of posts regarding Information security and VPN and here is the first article in this series.

You might be aware that the Indian government has started to block huge number of web sites these days and we are very annoyed of these bans over the internet. One way to access the open internet without any restrictions is using a VPN service.

Today I am going to introduce you to a VPN service provided by "Tunnel Bear". VPN is a technology which allows our data to pass through a secure connection.

virtual private network, also known as a VPN, is a private network that extends across a public network or internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
VPN encrypts and passes data to the private network. This provides an additional security to your data.

 Tunnel Bear VPN :

First of all you need to create an account on After which the download of VPN client will start automatically.

Install the client to your preferred location. Sign in to the client using your credentials.

After then you'll see the installed client, it has a creative and nice user interface :P  Click the ON switch to connect to closest tunnel and you can even select the country you want to route your traffic through. It may take some time though while connecting as it has to establish a secure and encrypted connection on both ends.

Also one thing you need to keep in mind is that if you have installed any antivirus then you need to provide permissions to Tunnel Bear VPN client to work properly.

In the free version you'll get 500 MB free data tunneling and there is an offer to get additional 1 GB data, you just need to tweet about tunnel bear from your twitter account.

So guys, this is all about Tunnel Bear VPN. I will do more research and find more such great VPN clients available and will write reviews about those in upcoming posts.

Lets keep the information security on first priority while accessing the Internet.
Thank you guys for reading this post, I hope you liked the article, let me know through the comments. More posts are coming in this series so stay tuned. :)

Li-Fi Technology Beyond The Expectations

Hey Webber

After a Long time i'm writing, but its said that never wait to do something new. This time we are going to look on a best technology called Li-Fi. It is Light Fidelity a way of transmitting data at large speed towards Smartphones, laptops and PCs.When the heading stuck into the mind it look like the Wi-Fi. The question will arise into your minds thats Is it Like Wi-Fi or something different ?
Don't worry I'm here to tell you to get deep understanding of this subject we have to through different following steps.
Lets Start

Wi-Fi Limitations

Capacity: Wireless data is transmitted through radio waves which are limited and expensive. It has a limited bandwidth. With the rapidly growing world and development of technologies like 3G, 4G and so on we are running out of spectrum.
Efficiency: There are 1.4 million cellular radio base stations that consume massive amount of energy. Most of the energy is used for cooling down the base station instead of transmission. Therefore efficiency of such base stations is only 5%.
Availability: Availability of radio waves is a big concern. It is not advisable to use mobile phones in aero planes and at places like petrochemical plants and petrol pumps. 
 Security: Radio waves can penetrate through walls. They can be intercepted. If someone has knowledge and bad intentions, they may misuse it. This causes a major security concern for Wi-Fi.

        What is Li-Fi Technology ?
        Li-Fi stands for Light-Fidelity. Li-Fi is transmission of data through illumination by taking the fiber out of fiber optics by sending data through an LED light bulb  that varies in intensity faster than the human eye can follow. Li-Fi is the term some have used to label the fast and cheap wireless communication system.
         Li-Fi uses visible light instead of Gigahertz radio waves for data transfer.It offers much larger frequency band (300 THz) ,RF communications is (300GHz).

         Li-Fi can be the technology for the future where data for laptops, smart phones, and tablets will be transmitted through the light in a room. Security would not be an issue because if you can‘t see the light, you can‘t access the data.

         The idea of Li-Fi was introduced by a German physicist,Harald Hass.Li-Fi is a fast and cheap optical version of Wi-Fi. It is based on Visible Light Communication (VLC) VLC is a data communication medium, which uses visible light between 400THz (780 nm) and 800 THz (375 nm) as optical carrier for data transmission.

 The main components of Li-Fi system are as follows:
                 A) A high brightness white LED which acts as a transmission source.
                 B) A silicon photodiode with good response to visible light as the receiving element.
LEDs can be switched on and off to generate digital strings of different combination of 1s and 0s. To generate a new data stream, data can be encoded in the light by varying the flickering rate of the LED.The LEDs can be used as a sender or source for Parallel data transmission.

        Wi-Fi – IEEE 802.11n Speed is 150 Mbps.Bluetooth Speed is 3 Mbps.IrDA 4 Speed is Mbps.
          Li-Fi Speed is More than1 Gbps .


         Capacity: Light has 10000 times wider bandwidth than radio waves.
       Efficiency: Data transmission using Li-Fi is very cheap. LED lights consume less energy and are highly efficient.
         Availability: Availability is not an issue as light sources are present everywhere.
         Security: Light waves do not penetrate through walls. So, they can‘t be intercepted and misused.
         Education systems :Class Rooms
