Appendix ABrief Introduction to Wireless Communication and Networking
A.1 Wireless Communication Basics
Similar to wired communication, a one-way (simplex) wireless communication requires a transmitter (transmitter electronics plus antenna) generating (electromagnetic) signals that can be properly received and deciphered by a receiver (receiving electronics plus antenna). Bidirectional communication requires a pair of transceivers—each transceiver consists of a transmitter and a receiver. Although it is possible for a transceiver to be designed such that it can transmit and receive at the same time, for various reasons such as the cost of the unit and its weight, a transceiver is designed with shared components (such as antenna) between its transmitter ...
