We decided to go with an XBee-PRO because of its range. This is the only wireless technology that is able to send a signal far enough for our project. 2.7 WIRE TRANSMITTION TECHNOLOGY: 2.7.1 DIRECT WIRE COMMUNICATION: Wired technology has been around since the early with the introduction of 1900’s the telephone network.
