"There are" many things happen, "said Ron Schmidt, director for Network Systems Performance for Verizon Wireless in Minnesota.

"The phone's base station is here again, and joined our headquarters," he said.

wave cell phone use RF (radio frequency) to transmit voice and data. To learn mobile equipment antenna tower whose signal is stronger and closer.

If you click Send, the signal through the air, hit the tower.

"It is the transformation of our connection to our fiber network and then transfer to the subway, our business partners," said Schmidt.

fiber line to take your call to the central computer (switch), you find that you are calling from a landline or another. When the mountain "fixed call routing system. If the phone number, call routing has recently returned to the tower and then moves through the fiber.

According to the Federal Communications Commission, which held the most dropped calls, and the unit when you call Tata benefit from cell to cell.

"The cell radius on land and various buildings," he said.

And radio waves can be difficult to penetrate steel buildings or in underground cellar. Therefore, is not your imagination, as he sat down, you get a better signal than the front.

"It is the edge of the signal, even in the smallest moving head antenna signal strength is different," said Schmidt.
