(question)scientific explanation of the baud rate and improves

Projects Programming

I need know what is the improve if i set a high baud rate to the arduino.
I got a SMS service, and i implement a simple baud rate of 9600, i want to increment the speed of my service.

My Questions and desires:

  1. The better the baud rate better speed of my service?
  2. The scientific explanation of the baud rate of arduino

I use arduino uno, GSM shield SIM900 and a java app with the library of panamahitek to connect my arduino with a java app.

THX.

it can increase my speed service if i use a high baud rate???

It increases the speed that the arduino transmits data. In order for the "service" speed to increase, other things have to be true as well:

  1. The device you are connecting to needs to support the higher baud rate.
  2. there can't be some other "path" with a slower transmission speed. If you have some sort of radio whose maximum transmission speed is 1200bps (which is not uncommon for some of the ultra-cheap radio transceivers), then increasing the baud rate between the radio module and the arduino from 9600 to 38400 will not have any significant effect on the overall service. (even if it's technically supported due to some buffering in the radio module that allows the arduino link to operate at a higher speed than the radio link.)

("Scientifically", a "baud rate" is the number of times a "signal level" changes state per second on a transmission line. Some communications gear (modems) implements techniques where there are more than two signal levels, so that the "baud rate" and the "bit rate" are NOT the same. However, you probably won't find it used this way in common practice.)

You want to send SMS messages faster? I think that is going to be limited by your network carrier. SMS was originally only a very slow service because it was intended for technicians as a diagnostic tool. It's now used by billions of people every day but it still doesn't need to work quickly for most of them.

You cannot make a train run faster by stuffing people into the carriages more quickly.

You can (a little) by reducing the time at stations.
