DO you know what is LTE and VOLTE?

LTE
It is a mobile internet technology, which is the abbreviation of Long Term Evolution.
In other word 4G and LTE are synonyms.
               Theoretically, LTE supports 100 mbps downloading speed aud  50 mbps uploading speed.
At present LTE is the fastest data transfer technology.

VOLTE
Full form of VOLTE is Voice Over LTE.
A technology where you can simultaneously send voice and data over the network without diminishing the quality of voice is known as VOLTE.

                 In case of LTE , if you make a voice call while keeping your data connection on, then you will find your voice quality reduced.
                 But in case of  VOLTE voice quality will not reduce even if your data connection is on.


Thank you , I hope you will like my post.

Internet of Things (IOT)

History of IOT

The concept  of Internet of things first became popular in 1999 by the Auto-ID center at MIT and related market analysis publications

Internet of Things definition: It is a vast network of physical devices or "things" embedded with electronics, software, sensors and network connectivity, which enables these things to collect and exchange data.
              IOT allows object to be sensed and controlled remotely across existing network infrastructure, creating opportunities  for more direct connection between the computer and physical world, and resulting in improved efficiency,  accuracy and economic benefits.

Difference Between Microprocessor and Microcontroller

Difference Between Microprocessor and Microcontroller

Microprocessor is an IC which contain only CPU inside it, RAM, ROM Timers and other peripheral are connected externally. A system designer has to add them externally to perform functionality. Application of microprocessor includes PC'S, Mobile Phones etc.

But in case of Microcontroller, It has RAM, ROM Timers, Counters, and other peripheral are inside a single chip. That's why it is termed as mini computer.

Today there are many manufacturers produces microcontroller with wide range of features in different versions. Some of manufacturers are ATMEL , Microchip, Motorola etc.

Microprocessor find applications where tasks are unspecific like developing software, games, web designing, photo editing,  etc. In such cases the relationship between input and output is not defined. They need high amount of resources like RAM, ROM, I/O ports etc. 

Microcontrollers are designed to perform specific tasks, where Specific means applications where the relationship of input and output is defined. Depending on the input, some processing needs to be done and output is delivered. For example, keyboards, mouse, washing machine, remote, microwave, cars, bikes, telephones etc.

Clock speed of Microcontroller is a few MHz to 50 MHz but Today’s microprocessor operate above 1GHz as they perform complex tasks.

Sensors used in smart phones

There are many sensors used in smart phones. To facilitates better user experience sensors are used in mobile phones.
Some of the sensors are- Proximity Sensor, Accelerometer and  Gyroscope, Light sensor, Digital Compass etc. 

Proximity Sensor 

It detects the presence of the object near to the phone. Placed near to the earpiece of the phone for a reason  that- when you place the handset up to your ear then it turn off the display. This saves battery life as well as prevents accidental screen touch.

Accelerometer and Gyroscope

A sensor that measure proper acceleration. It is used to detect the orientation of the handset.

An accelerometer measures movement of linear acceleration while on the other hand  Gyroscope measures movement of angular velocity.

Light sensor

The function of ambient light sensor is to adjust the display brightness. Ultimately it saves battery power  as well as life.

The sensor adjust brightness according to the intensity of  the light.

Digital Compass 

The function of compass is to give proper direction with respect to North pole and South pole of the earth.
