Well, the generic answer is yes but the real answer depends on what you have and what you want.  Details are important.  ??
What do you mean by a tower and satellite?  If you're talking about a satellite in orbit, that requires a lot of power (but satellite phones can do it).
I cannot offer a solution with this limited infomation....please clarify your needs.

Thanks for your responses. Consider a digital equipment that needs to send a signal. Just an example, I'm using a micro-controller which using a sensor to calculate a phenomenon and now the results of this calculation is set of number and it is necessary to transmit the data to a receiver.  My question is that what kind of techniques are available to send that set of number of web server/application or any possible gateway to store them in a database.

If it's connected to a network, you can just perform some socket programming and write it directly to a remote server, or ftp it.  If it's not connected, you can store it in a file and schedule it to connect to a network or passively wait until it is connected, then transfer the files.  Local storage can be a flash drive.
