Difference between 3G and 4G

iphone5 has launched with the compatibility of 4G technology. After which question arises what is the difference between 4G and other technologies. Right now, we are generally using 3G technology in our communication devices. 3G was considered the best and high speed communication technology until 4G had not arrived.

When iphone5 has launched, the question comes what is 4G and what are its advantages over others?

4G: Fourth Generation is the latest generation of telecom services after 2G and 3G. It represents higher data speeds and faster downloads. 4G technology works on LTE can offer as much as 100 Mbps in ideal conditions and may, like 3G, see practical hitches.

	3G	4G
Ideal/Actual Speed	28Mbps/3.1Mbps	100Mbps/14Mbps
Ideal/Actual Download Time(movie)	30 min/5 hr 10 sec	19 mins/2 hr 50 min

Advantages:

1. Multimedia application - such as e-learning, high-definition videos, tele-medicine

2. Seamless online streaming - you can watch and play videos and songs without buffering. It is capable of transferring high speed data.

3. Online Gaming - you can easily play HD games online only without interruptions like buffering occurs in 3G and 2G.

4. Business applications - It supports and play high speed software online. Business applications required higher speeds and last-mile connectivity.

5. Cloud based applications - where data is stored on remote servers and accessing via Internet.

Buzzer interface with 8051 microcontroller

Buzzer is a electronic device that converts the electronic signal into buzzing noise, that is applied to it. It can be used as electronic bell or as quiz buzzer in many applications around us. Here, i world like to discuss the interfacing of a small buzzer with 8051 microcontroller and how different projects can be constructed. Buzzer Interfacing: This project shows the interface with AT89S52 microcontroller to a buzzer. When a push button is pressed, the buzzer will get ON and OFF ( number of times set in the code ) and then stops. Circuit Diagram: - The port P1 of the microcontroller is connected to buzzer. This type of connection is possible, if the current requirements of the buzzer is not more than 20mA. The output is in current source mode so that buzzer will turn ON when the output of the port is logic LOW. Switch is connected to port P3 which remains at logic HIGH by pull up resistor. Code: #include "REG52.h" #define buz P1 sbit SW=P3^0; long int i; voi

How to Switch OFF Citizen Calculator

You might be confused on seeing no OFF button on your calculator. Actually, these are general calculator available at low cost in the market. They process simple calculations like division, subtraction, Addition, Multiplication. But, how will you OFF that calculator having no option on them. There is always a trick which OFF them. It depends on the company calculator and their series to which they belong. I can tell you about Citizen Calculator CT-500 (as you can see in the image), how can you switch OFF it and can save battery too. If you leave calculator idle for 6-7 minutes, it will goes OFF automatically. My calculator goes OFF in 6.50 minutes from the point of leaving it idle. But, this is not the power saving trick for these types of calculator having not much backup battery. To save the power of your normal calculator, here is the trick to switch OFF it. Press ' /(divide sign)', 'x(multiply sign)', '%(percentage sign)', 'autoreplay option(

Different ways to generate delays in 8051

The delay length in 8051 microcontroller depends on three factors: The crystal frequency the number of clock per machine the C compiler. The original 8051 used 1/12 of the crystal oscillator frequency as one machine cycle. In other words, each machine cycle is equal to 12 clocks period of the crystal frequency connected to X1-X2 pins of 8051. To speed up the 8051, many recent versions of the 8051 have reduced the number of clocks per machine cycle from 12 to four, or even one. The frequency for the timer is always 1/12th the frequency of the crystal attached to the 8051, regardless of the 8051 version. In other words, AT89C51, DS5000, and DS89C4x0 the duration of the time to execute an instruction varies, but they all use 1/12th of the crystal's oscillator frequency for the clock source. 8051 has two different ways to generate time delay using C programming, regardless of 8051 version. The first method is simply using Loop program function in which Delay() function i
